Why Is Sleep So Important
One of the most important things I deal with in my practice is sleep. Sleep is defined as “a naturally recurring state of mind and body characterized by altered consciousness, relatively inhibited sensory activity, reduced muscle activity, inhibition of nearly all voluntary muscles, and lacking interactions with surroundings.” All animals need to sleep. Evolutionarily, in order to survive and successfully pass on genetics to another generation, sleep is a necessity. Humans are animals in this regard; we’re no different, as we require sleep to live too. And while it is a naturally occuring state, for some people, getting sleep is an absolute battle, fought tooth and nail every night.
Just some fun facts about how a few animals sleep… Can you imagine sleeping for as little as 30 minutes a day? How about for only five minutes at a time? Our giraffe friends can, because that’s exactly what they do. For a large animal in the middle of the open savanna, it’s risky to sleep because of predators. They must remain vigilant, so they nap in short intervals, usually standing up so that they are always ready to run. Dolphins and some of their marine mammal cousins are also unusual in that, unlike us, they must consciously think to breathe, even when they’re sleeping. They also have to be on guard 24/7 for predators or other potential dangers. So how do they do this? Well, they shut down only half of their brain at a time while sleeping. This is called unihemispheric sleep. This prevents them from drowning, while at the same time, allowing them to literally sleep with one eye open and remain on the lookout for potential danger or predators. Great Frigatebirds can stay in flight for months at a time, with their feet never touching ground. This is an impressive feat, but even more so when you think about how they sleep: in 7–12 second bursts. They spend approximately a total of 40 minutes sleeping like this per day while also flying. But when they are on land, they do sleep considerably more.
We humans can’t shut down half of our brains and we can’t fly or sleep underwater, which is a bummer. But really, how important is sleep for humans? Very! Rats are used in research because they accurately portray human systems, and there have been many sleep studies with them. One study showed that rats deprived of sleep for two weeks die. There is even an illness in humans called fatal familial insomnia, where if the people that have it do not sleep, they will eventually die from the cumulative lack of sleep. So let’s talk sleep. Sleep is basically the price we pay for the privilege of being awake, and there’s no way around it. So we have to pay the piper, but what’s the price? How much sleep do we need? The answer is that the vast majority of people need 7 to 9 hours of sleep per night. But, there is an exception. Five percent of the population has a genetic mutation where they only need five hours of sleep per night. Lucky ducks! Fun fact: in the past 50 years, the amount of sleep the average American gets has dropped by about an hour and 15 minutes to an hour and a half each night. That’s actually a lot, and there are consequences in our modern lifestyle. Also, you can’t bank sleep. You can’t say, ‘I slept an extra four hours over the weekend, so I can lose at least four hours of sleep tonight in order to get my big project done at work.” or “I won’t sleep much this week so I can study for a test, but I’ll make up the sleep this weekend.” Nope. It doesn’t work like that. More often than not, you really need to be on a regular sleep schedule, getting about the same number of hours each night. I treat sleep issues more than anything else in my practice. Hands down, every patient who comes in has a problem with sleep. With some people, I can do behavioral management; with others, I use meds or natural supplements. I’ll get to that later. When I’m lecturing, I always get questions about how one spouse gets up early and the other late and is that normal, etc. Yes, that is totally normal. There are certain genetic types, called chronotypes. There are larks, people who get up early, but then go to bed early. And there are night owls, who go to bed very late, and then wake up very late. Your genetic makeup determines what your chronotype is, whether you are a lark or a night owl, it’s perfectly healthy to be either. It doesn’t matter when you sleep, what matters is that you sleep. Ideally seven to nine hours a night. Adolescents sleep more, up to 12 or 14 hours per night, and newborns sleep for 16 or 17 hours each day, mainly because these are growth stages, and that tires the body. But by the time you reach adulthood, age 20 or so, you need that seven to nine hours. It is a myth that older people need less sleep. In reality, they need just as much sleep. The reasons they don’t sleep well can be because they are in pain, have bladder problems and need to use the bathroom, or all the medicines they are on disrupt the sleep architecture. A lot of neurostimulants, diuretics, and other drugs that make them drowsy during the day make it so they do not sleep well at night. It can be a really frustrating mess that’s difficult to untangle.
I want to talk about the reasons why we need sleep. Like many things in life, the reasons why are essentially based on the consequences of not getting it.
The brain makes up just two to three percent of our body mass, but it consumes 25% of the body’s energy. It’s like a car that’s running really fast; as the car burns gas, it makes fumes. Similarly, when the brain is burning calories, it creates waste. That waste is cleaned out when we sleep, and is why most people need 7 to 9 hours per night. Now, some people think they can avoid sleep and just drink coffee or energy drinks, but that’s wrong. One of the byproducts of our brain using all the energy it does is the production of a waste product called adenosine; and it takes sleep to get rid of it. Caffeine blocks the body’s sensors that this toxin is building up, not unlike having a car running in your house. If you ran your car in your garage or house, carbon monoxide would build up and eventually you would die of carbon monoxide poisoning. Caffeine blocks the body’s ability to determine how much adenosine is in it, so the body is tricked into thinking all is well, no need to rest. If it goes on too long, there are consequences to pay, and you eventually collapse.
A story on this topic that I find interesting is one about Randy Gardner, who holds the world record for sleep deprivation. There is some dispute about that, another dude named Tony Wright claims the record is his, but whatever. Anyway, Randy was a high school student in the 50’s and he had a science fair project to do. After much thought, he decided to study sleep deprivation. Randy decides he wants to prove all of his teachers wrong by showing them that people don’t really need sleep. He was normally a pretty affable guy, but right about day two, he started getting moody. Then he started having major problems concentrating at about third or fourth day. On day five, they tell him to start at 100 and to keep subtracting seven. He said “okay, 100 minus 7 is 93, minus 7 is 86, minus 7 is 79, minus 7 is…is…72, minus 7…no, minus 9 is 79, minus 7…wait…what am I adding? I mean…subtracting?” He was totally lost after just three subtractions. When they asked why he stopped, he couldn’t even tell them what he had been doing. And he was not a dumb kid, he was actually a straight A student. It was clear that missing four nights of sleep was clouding his mind to the point that he couldn’t remember simple directions. His inability to concentrate and his short-term memory loss was due to the fact that his brain and body were severely sleep deprived. But he still carried on with the experiment. Then something bizarre started happening around day six and seven. He started checking the windows in his house, making sure they were locked. Then he started looking for people watching him. He was sure that his friends were conspiring against him, and was constantly checking around corners, pulling down shades, and drawing the curtains on the windows in his house. If his mom opened them, he would freak out and hide in his room. Then he started saying that not only were they watching him, they were plotting against him. These people he was referring to were his best friends, but he was sure they had an evil agenda to get him. He still refused to stop his experiment, but his mother convinced him to see his doctor. It backfired: the doctor wanted to give him a B-12 injection, but when the syringe came out, Randy ran out of the room, convinced that the doctor was trying to poison him. He was going downhill very fast. On the eighth day, he started hallucinating, seeing and hearing things that weren’t there. Then he started having problems with pronunciation of simple words; a straight A student couldn’t pronounce everyday words. All because he had not slept, he had not allowed the brain and body to rest, to rid themselves of toxins. Then he stopped recognizing everyday objects. They would put a fork in his hand, and he couldn’t say what it was or what it was used for. By this time, he was like a zombie, walking dead. By the ninth and tenth day, he lost his sense of smell, and then his vision became progressively more blurry. By the eleventh day, he collapsed. He was emotionally, mentally, and physically done. His brain had given out first, then he started to lose normal bodily function, until his body finally gave up. He went 11 days without sleep. That’s 264 hours. 15,840 minutes. They didn’t say how long he finally slept. I suspect he was actually just unconscious at first. And they didn’t say what he got for a grade on his science fair project. I’d like to think it was an A, since the kid basically risked his life for the stupid thing. He went from a smart, gregarious kid to a babbling idiot in eleven days flat.
Lots of bad things happen when people don’t get enough sleep. In sleep deprived adolescents, the suicide rate goes up dramatically. In all ages, but more so in adolescents, the risk of car accidents also goes up considerably. There is also an increased tendency for moral lapses in people who do not get enough sleep; they do things that are typically out of character for them, like rob people or cheat on their spouses. Sleep deprivation also leads to learning problems, regardless of age; studies have shown that the capacity to learn is reduced by 40% when people are sleep deprived. That’s huge! It also causes an inability to recognize facial expressions. You may ask why that’s a big deal. Well, if you can’t tell that you’ve pissed off the big thug on the subway, you might continue to unwittingly irritate him and get yourself beat up… or worse. Reaction times are greatly affected by sleep deprivation; they’re slowed severely. That’s why car accidents increase. But researchers have thoroughly studied sleep and reaction times in sports. Many studies on sleep deprivation come from basketball players. Their accuracy and their performance metrics all go down relative to the hours of sleep missed. Hockey players’ reaction times, after just one night of missed sleep, were off by 30%. A goalie’s reaction time down by 30% is dramatic when it translates to the other team scoring on him 30% more often.
It’s all about getting that seven to nine hours. There are lots of physiological consequences of sleep deprivation. Blood pressure goes up, the risk of heart attack goes up, the risk of stroke goes up, you become obese, and often diabetic as a result. There’s actually a mechanism for it that I’ll explain in a moment. A host of psychiatric and mental illnesses can result from lack of sleep, and studies have shown that people who are chronically sleep deprived die much younger.
Now, let’s talk about your endocrine system. The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things. So, it pretty much controls like… everything. In young males, sleep deprivation makes the testosterone levels drop. The ability to produce testosterone is decreased in men who sleep less than six hours a night. What does that mean? Only that their testicles get smaller, they can have erectile dysfunction, and reduced sex drive. In adolescents, it can hamper the development of the bones and muscles, the deepening of the voice, and hair growth; all the stuff that helps boys start to look, sound, and act like men. It has an analagous affect on women, in that fertility goes down and estrogen levels decrease with chronic sleep deprivation. But in a cruel and ironic twist, a decrease in estrogen has been shown to cause insomnia and less productive sleep, or just very poor sleep. So for women, it’s often a vicious cycle.
What else happens to your hormonal system when you do not sleep? I’m sure you can correlate a lot of this stuff with your real life experiences. When you can’t or don’t sleep, do you notice you crave junk food? It’s 3am and you’re standing in the kitchen, scarfing down cold pizza? Or some other high fat or high sugar thing…a big bowl of cereal or ice cream or a doughnut, or three? Or a cinnabun? I love those and I must have one every time I’m at the airport, those are good. Anyway, that’s a distraction- I didn’t mean to bring that up. Remember earlier when I said that I’d explain why obesity is so much more common in people who are sleep deprived? Here we are. So what happens to you’re endocrine system when you don’t sleep? For one thing, you secrete a hormone called ghrelin. Ghrelin is a gnarly beast of a hormone, high on the list of the most hated hormones ever in the history of hormones. It even sounds like the name of a goblin, right? And not a nice goblin. A bad, mean, evil goblin. Ghrelin the gnarly goblin. Why the shade? Ghrelin is the hormone that makes you hungry…and hangry. So here you are, middle of the night, can’t sleep. And all of a sudden you’re starving! Why? Because not sleeping has triggered the release of a crap load of ghrelin, and it’s coursing through your body, making you crave sugary, fatty foods… whatever doesn’t run away when you reach for it is fair game. Ain’t that a bi-otch? But that’s not the worst of it. Ghrelin the goblin has a goody goody cousin named leptin. Leptin is the hormone that makes you feel full. He’s nowhere to be found when the gnarly goblin ghrelin is out on the prowl. So not only are you starving courtesy of ghrelin, but goody goody leptin is home studying, so you won’t be seeing him or feeling full anytime soon. So before you know it, you’ve eaten all the leftover pizza, a bowl of cereal, and a giant bowl of cookies & cream topped with more cookies and whipped cream! And you’re still eyeing the rest of that baked chicken in the fridge. But wait! The hormonal chemical conspiracy isn’t over friends. Without leptin to make you feel full, ghrelin the goblin has made you eat everything that’s not nailed down, but somebody else is coming to join the party…cortisol. Dahn dun duuuuuhhhnnn! Cortisol is the stress hormone, and he gets produced at higher levels when you don’t sleep. When he gets to the party, he pushes insulin around (they have a terrible history; don’t even ask) so insulin feels emasculated, so his levels go down. Why should you care about insulin levels? Well, remember all the carbs and sugar that ghrelin made you gorge on? Insulin is what helps your body break all that down. But since cortisol came to the party, pushing insulin around, all those sugars have nothing to do. What does that sound like? Begins with a “d”? Diabetes! Obvi you don’t become diabetic from one 3am rendezvous with the Frigidaire, but it sets up a diabetes-like condition that leaves those sugars all dressed up with nowhere to go. If that happens chronically, you can end up with diabetes. So what happens to these loose sugars at 3am? They go to fat. It’s squishy and warm there, a great place to land. It’s a whole cascade, a hormonal conspiracy to make you fat and…and…ugly! For real?! How does that happen? The cascade continues! Growth hormone doesn’t get along with cortisol either, so when cortisol shows up, growth hormone is outta there. When growth hormone leaves the party, that’s really a bummer, because he’s what basically restores the body, especially parts of it that are very important to a certain industry…the beauty industry. You now know that not sleeping can make you fat, but how can it make you ugly? Well, check back next week and I’ll tell you!

And people, for better or worse, it seems like the world is re-opening once again, so just please make wise choices. Maintain a little distance, don’t rush out to bars and dance floors to make up for lost time, and if you’re sick, stay home for God’s sake! And bosses, remember the lessons that corona taught us: let your people stay home if they’re sick; don’t make them choose between their health and their livelihood. I’ll now step down off my soapbox. Have a great week!

Learn MoreObesity:What Causes it and How to Combat it
We’re nearly six weeks into the new year, and this is right about the time that most people toss their new year’s resolutions out the window. Many of them had resolved to lose weight: surveys have shown that, of the people who make new year’s resolutions, an average of 45% of them resolve to lose weight and get in better shape. So that means that nearly half of resolution-makers are overweight at least. That number seems high, but given that obesity has reached epidemic status, I guess it’s not that surprising.
Obesity is broadly defined as the state of being well above one’s normal weight. Obesity often results from taking in more calories than are burned by exercise and normal daily activities, aka ‘eating too much and moving too little.’ A person has traditionally been considered to be obese if they are more than 20% over their ideal weight. That ideal weight must take into account the person’s height, age, sex, and build. Obesity has been more precisely defined by the National Institutes of Health (NIH) by utilizing a person’s BMI, body mass index. The BMI is a key index for relating body weight to height, and it is formulaic. The imperial BMI formula is weight (in pounds) multiplied by 703, then divided by height (in inches²). If you don’t feel like dealing with the math, you can google a BMI calculator. Having a BMI of 30 and above is considered obesity. Over 70 million adults (35 million men and 35 million women) in the U.S. are obese, while 99 million (45 million women and 54 million men) are overweight and at risk for becoming obese.
What are the causes of obesity? Obesity can be complex, going beyond eating too much and moving too little. Following are some other factors that cause or contribute to obesity.
Genetics
Obesity has a strong genetic component. Genetic predisposition means that children of obese parents are much more likely to become obese than are children of lean parents. Genetics also affect the rate at which the body uses energy (burns calories) when at rest, which is called the basal metabolic rate. People with higher basal metabolic rates naturally burn more calories than other people, so they are less likely to gain weight. The opposite is also true: people with lower basal metabolic rates burn fewer calories, so they are more likely to gain weight. But these facts don’t mean that obesity is completely predetermined, that there’s no way to change it. What you eat can have a major effect on which genes are expressed and which are not. This is demonstrated when people of non-industrialized societies come to the U.S., begin a western diet, and then rapidly become obese. Obviously, their genes didn’t change, but their diet did; that changed the signals they sent to their genes, which then changed the expression of the genes. Changing the expression of the genes resulted in obesity. The bottom line is that genetics do play a key role in determining susceptibility to gaining weight and obesity, but that is only one factor of many; it is not all genetically predetermined.
Diet: What and How You Eat
Obviously, eating an unhealthy diet is a major contributing factor in obesity. Overeating at meals and snacking throughout the day can also lead to obesity. An unhealthy diet would be high in complex carbohydrates, bad fats, and sugar, and low in fresh fruits, vegetables, and high protein lean meats. There are social factors that affect diet and therefore weight. If you spend a lot of time with overweight friends and family who eat too much of an unhealthy diet, the odds are that you’ll be overweight as well. Economic factors also play a role in obesity. If you can only afford cheap, ready-made packaged foods or fast foods from the dollar menu, you are much more likely to be obese. Economics may force you to eat a diet high in complex carbs like pastas, breads, potatoes and rice just to fill yourself up, because that is all you can afford. That type of diet greatly increases the risk of obesity. Unfortunately, eating unhealthy foods and overeating are easy in our culture today. Many things influence eating behavior, including time with family and friends, the low cost of unhealthy but filling foods, and the access to and expense of healthy foods.
Lifestyle
If you have a lifestyle that centers on eating and/ or drinking, this can contribute to excess weight. A chef, bartender, or baker, something that requires tasting various dishes and trying new recipes for example. Also, someone who travels a lot for their job so always eats at restaurants, which are notorious for hidden calories and fat; they are more likely to be overweight and at risk for obesity. A sedentary lifestyle, where there is little to no activity or exercise is a huge contributing factor in being overweight or obese. Our modern conveniences- elevators, cars, remote controls- have cut activity out of our lives. The problem is that the less you move, the less active you are, the more likely you are to be obese. Being active helps you stay fit. And when you’re fit, you burn more calories, even when you’re resting, so you’re less likely to be overweight or at risk for obesity.
Medical Conditions
There are a host of medical issues that can cause or contribute to significant weight gain. Some examples are hypothyroidism, diabetes, Cushing syndrome, polycystic ovarian syndrome (PCOS), menopause, depression, and endocrine dysfunction. Some medical issues don’t cause weight gain in and of themselves, but make weight gain more likely because they limit the person’s activity. Some examples would include conditions like osteoarthritis, uncontrolled rheumatoid arthritis, and chronic pain syndromes.
Medications
The list of medications that can cause weight gain is a long one. Everyday medications like corticosteroids (Prednisone, Celestone), diphenhydramine (Benadryl), hormone replacements/ birth control, and even insulin are among the culprits. Sometimes it’s not the drug itself causing weight gain, it’s a side-effect from the drug. Some drugs stimulate your appetite, and as a result, you eat more. Others may affect how your body absorbs and stores glucose, which can lead to fat deposits in your body. Some cause calories to be burned more slowly by altering your body’s metabolism. Others cause shortness of breath and fatigue, making it difficult to exercise, while some drugs cause you to retain water, which adds weight but not necessarily fat. Some medications don’t cause you to gain weight outright, they just make it more difficult to lose excess weight you may already carry. A lot of psychiatric medicines cause weight gain. The worst offenders generally include mirtazapine (Remeron), paroxetine (Paxil), risperidone (Risperdal), aripiprazole (Abilify), and quetiapine (Seroquel). With the exception of Wellbutrin, essentially all classes of psychiatric meds can be associated with serious weight gain. As a psychiatrist, I have to prescribe meds that may cause an unwanted side effect like weight gain. I have to weigh the cost to benefit with each patient. Unfortunately, I have patients who are trapped; they must take certain medicines to remain stable, so they have to severely alter their food intake and diet every day of their lives in an effort to avoid weight gain if possible. That’s the cost to benefit ratio- they pay the cost of a severe diet in order to get the benefit of being stable psychologically.
Why should you care about your weight? What health issues does being overweight cause? The answer is many. Obesity leads to type 2 diabetes. It causes high blood pressure, which can cause strokes. Obesity can increase cholesterol levels and cause coronary artery disease, which is where deposits line the blood vessels that feed the heart and partially or totally block them, so the heart does not get adequate blood supply; this results in a heart attack, aka a “coronary” and this can easily be fatal. Being overweight puts excess weight on the human body, and this commonly causes osteoarthritis of major joints like the knees, the hips, and the ankles. All parts of the body are stressed and strained because they are not designed to carry around that much weight, and this limits the range of motion, mobility, and ability to walk. Obesity increases the risk of cancer to several organs and body parts: the breast, colon, gallbladder, pancreas, kidney, prostate, uterus, cervix, endometrium, and ovaries. Another common medical issue from being overweight is sleep apnea. All the weight on the chest and throat causes you to temporarily stop breathing when sleeping, until you finally noisily gasp for air. Sleep apnea is serious, and very disturbing for anyone that you share your bed with. Obesity causes a fatty liver, which then leads to liver disease and the potential to cause the liver to shut down. Obesity can cause gallstones as well as kidney disease, which can cause your kidneys to stop functioning. Obesity can also cause fertility problems in both men and women. As a psychiatrist, I get obese patients referred to me because obesity can directly cause, or indirectly lead to, various syndromes and other issues, including chronic pain syndromes, depression syndromes, isolation syndromes, social problems, self esteem issues, and difficulty dating. People who develop obesity, especially when it is the result of something beyond their control, like from a medical issue such as hypothyroidism, have all sorts of social interaction issues and work problems, and I can treat them and help walk them through it with psychotherapy.
We defined obesity, discussed the risk factors and what can cause it, and then the issues it can cause. Now let’s discuss how we can lose weight and prevent obesity.
Food Diary
To offset weight gain or to help work off excess weight, consider keeping a food diary tracking what you eat and when you eat. Becoming a mindful and aware eater is a great first step to managing weight.
Eat Slowly
Another factor which helps with weight loss is eating slowly. It takes some time for your stomach to tell your brain that you’ve had enough to eat. If you mindlessly shovel huge amounts of food into your mouth, you’ll miss your cue and overeat, and that obvi will cause you to put on weight and increase the risk of obesity. Eating slowly also has the added benefit of reducing the chances of having indigestion.
Get Physical
Become more active whenever possible. Instead of meeting someone for coffee or a movie, meet them at a park, beach, or green space and go for a walk. Ideally, you want aerobic activity; that means getting your heart rate up, when it’s harder to breathe. Aerobic activities mean constant motion, like running, biking, swimming, soccer, basketball, anything where you’re moving constantly. Constant activity is aerobic activity, and daily aerobic activity will raise your basal metabolic rate and you’ll burn more calories, even when you’re at rest.
Resist It
Resistance training is good for targeting fatty areas on the body. Resistance training involves moving a specific muscle against resistance, either using your own body weight or using standard weights. Other activities like lifting weights, doing push-ups, and doing squats are good for reducing body fat.
READ LABELS!
…and make sure you understand them. If you don’t understand them, do some research, get a library book on nutrition, ask a friend if they understand, or ask your doctor what the values all mean and how much of the various components should be included in a healthy balanced diet or when dieting in an effort to lose weight. Pay close attention to calorie count, fat grams, protein grams, sugar grams, and carbohydrate count. Just because something says “light” doesn’t mean it should be included in your diet. So many people are ignorant about nutrition information on food packaging. Be sure to know what those values mean and how much you should have of each every day.
Know the Fats
Trans fats- Bad fats!
Historically, trans fats are an evil on par with Satan himself, to be avoided at all costs. The worst type of dietary fat, trans fat is a byproduct of the industrial process of hydrogenation, which turns healthy oils into solids to prevent them from becoming rancid. Eating foods rich in trans fats increases the amount of harmful LDL cholesterol in the bloodstream while reducing the amount of beneficial HDL cholesterol. Trans fats create inflammation, which is linked to heart disease, stroke, diabetes, and other chronic conditions. They contribute to insulin resistance, which increases the risk of developing type 2 diabetes. Even small amounts of trans fats can harm health: for every 2% of calories from trans fat consumed daily, the risk of heart disease rises by 23%. Mind blowing. Though they have no known health benefits, trans fats were found in most pre-packaged garbage foods and were the main component in margarine type spreads. I say ‘were’ because recent science found there is no safe level of consumption of trans fats, and as a result, trans fats have been officially banned in the United States and several other countries.
Monounsaturated fat- Good fats!
Evidence has shown that consuming monounsaturated fats has several health benefits, including reducing general inflammation in the body. Studies have also shown that a high intake of monounsaturated fats can reduce triglycerides, decrease the risk of heart disease, and lower bad LDL blood cholesterol while increasing good HDL cholesterol. A diet with moderate-to-high amounts of monounsaturated fats can also help with weight loss, as long as you aren’t eating more calories than you’re burning. These fats are liquid at room temperature. Good sources of monounsaturated fat include avocados, almonds, cashews, peanuts, cooking oils made from plants or seeds like canola, olive, peanut, soybean, rice bran, sesame, and high oleic safflower and sunflower oils.
Polyunsaturated fat- Good fats!
The two types of polyunsaturated fats (omega-3 and omega-6) are essential fats, meaning they’re required for normal bodily functions, but your body can’t make them, so you must get them from food.
Omega-3 fats are a type of polyunsaturated fat that, like other dietary polyunsaturated fats, can help to reduce your risk of heart disease. Omega-3s can lower heart rate and improve heart rhythm, decrease the risk of clotting, lower triglycerides, reduce blood pressure, improve blood vessel function and delay the build-up of plaque in coronary arteries.
Omega-6 is a polyunsaturated fat that lowers bad LDL cholesterol. Eating foods with unsaturated fat, including omega-6, instead of foods high in saturated fats helps to get the right balance for your blood cholesterol (ie lower bad LDL and increase good HDL). Sources of polyunsaturated fats include oily fish (like salmon, mackerel, sardines), tahini (a sesame seed spread),
linseed (flaxseed) and chia seeds,
soybean, sunflower, safflower, and canola oil, margarine spreads made from those oils, pine nuts, walnuts, and Brazil nuts.
Follow these easy ideas for getting the balance of blood cholesterol (LDL and HDL) right.
– Go nuts! Nuts are an important part of a heart-healthy eating pattern. They’re a good source of healthier fats, and regular consumption of nuts is linked to lower levels of bad (LDL) and total blood cholesterol. So, include a handful (30g) every day! Add them to salads, yogurt, or your morning cereal. Choose unsalted, dry roasted or raw varieties.
– Go fish! Include fish or seafood in your family meals 2 – 3 times a week. Fish are great sources of the good omega-3 fats. If you don’t eat fish, you can take an omega-3 supplement.
– Use healthier oils! Choose a healthier oil for cooking. For salad dressings and low temperature cooking, choose olive, peanut, canola, safflower, sunflower, avocado or sesame oils. For high temperature cooking, especially frying, choose olive oil or high oleic canola oil, as they are more stable at high temperatures. Store oils away from direct light and heat and don’t ever re-use oils that have been heated before.
Eating polyunsaturated fats in place of saturated fats or highly refined carbohydrates reduces blood pressure, raises good HDL cholesterol, reduces harmful LDL cholesterol, lowers triglycerides, and may even help prevent lethal heart rhythms.
Saturated fat- OK in strict moderation
Saturated fats are common in the American diet, and they are solid at room temperature- think along the lines of cooled bacon grease. Common sources of saturated fat include red meat, whole milk and other whole-milk dairy foods, cheese, coconut oil, and many commercially prepared baked goods and other foods. A diet rich in saturated fats can drive up total cholesterol and tip the balance toward more harmful LDL cholesterol, which can prompt heart disease from blockages formed in arteries in the heart and elsewhere in the body. For that reason, most nutrition experts recommend limiting saturated fat to under 10% of calories a day. Replacing excess saturated fat with polyunsaturated fats like vegetable oils or high-fiber carbohydrates is the best bet for reducing the risk of heart disease.
Diet Do’s
– Eat plenty of fiber. Fiber fights belly fat. When ingested, fiber goes into your system, binds to and then forms a sort of gel with the food, which slows down the absorption of food in the gut.
– Eat a high-protein diet. Eggs are eggsellent…high in protein and low in fat. Avoid red meat. All meats should be lean and high in protein, like chicken or turkey. Nuts are also good for a protein snack.
– Eat fish, as often as 2-3 times per week for good omega-3’s. As discussed above, oily fish like salmon, mackerel, and sardines are high in omega-3’s which are good for the brain, help to decrease weight, and have numerous other health benefits. If you don’t eat fish, take a good omega-3 supplement.
– Drink green tea; there are reports that it helps with weight loss, and it’s generally just good for you.
Diet Don’ts
– Don’t eat sugary foods or anything with sugar in it: sodas, candies, cakes, cookies, doughnuts; those are the main culprits. It’s a major bummer, but to avoid weight gain in your life, much less to try to lose weight if you’re already overweight, you must avoid sugar like the plague. Wah wah wah…
– Cut out the carbs! To lose weight or just to avoid putting weight on, anything with white flour must go, so say syonara to pasta and most breads. You have to cut way down on starches, if you’re allowed them at all, so there goes rice and potatoes. And while most people consider corn a vegetable, you must count it as a starch when dieting.
– Get on the wagon! If you drink alcohol, you won’t lose weight and keep it off. Won’t happen. When you consume booze of any sort- beer, wine, liquor- the alcohol is immediately converted to sugar, and if you’ve forgotten, see Diet Don’t 1 above. There’s no point in restricting calories, fats, etc by following a diet and also drinking alcohol at the same time, even a small amount.
Go to Bed!
Sleep is critical if you want to lose weight, so aim to sleep at least 7-8 hours each night. If you do not get proper sleep, it will be very difficult (if not impossible) to lose weight, and you will likely gain weight. This is all thanks to brain chemistry and hormones, which get all fouled up with sleep deprivation.
Stress Less!
You have to reduce stress if you want to lose weight. When you are stressed, your body produces the stress hormone cortisol, and cortisol increases appetite and increases belly fat by selectively placing fat deposits around the stomach and middle of the body.
A Fast Fast
We’ve always been told that starving ourselves will not result in weight loss, and that it will even result in weight gain because the body goes into ‘starvation mode.’ Well, there are some recent studies out there that conclude that intermittent fasting, 24 hours without eating, once or twice a week, actually helps with weight loss. Very interesting.
So that’s all about obesity: what causes it, what it causes, and how to combat it. We are a fat society, and the number of cases of obesity goes up every day. It’s disturbing because it’s essentially a preventable issue.

Learn MoreHow To Sleep Better At Night
Slumber, shuteye, repose, siesta, snooze…Sometimes we have a love-hate relationship with it…we love it when it’s good and curse it when it’s bad, but we all need it. Whatever you call it, one complaint I hear from patients day in and day out is that they have difficulty sleeping. It’s so prevalent that I want to discuss how to get better sleep. In my 30 years of practice, I’ve compiled a list of 14 things in no specific order that you can do that should have you snoozing at night night in no time.
Rule 1: Bright light during the day. Your body has to have bright light during the day; sunshine is best, but even sitting in a bright room, like by a window, is helpful. Bright light tells your brain that it is day time, time to be awake. Darkness or the absence of bright light tells the brain it is night time, time to sleep. If you’re in a dark room all day, you probably won’t sleep well at night. So remember, in the day time, bright light is right.
Rule 2: Limit blue light. What is blue light? Blue light is what is emitted from your computer, laptop, and smartphone. The more blue light you are exposed to, especially at night, the more disruption you’ll have in sleep, as it disrupts circadian rhythm. Lots of people climb into bed with their cell phone or iPad, and that’s the worst thing to do. You should avoid looking at bright screens beginning two to three hours before bed. There are apps you can install on your phone that filter out the blue light. There’s also something called “F. Lux” that you can put on your computer or iPad which will block out the blue light. You never hear about it, but blue light exposure, especially at night, is a major factor in hindering sleep.
Rule 3: Captain Obvious here with a newsflash. Caffeine will keep you up at night. Don’t think you’re going to have coffee or tea after dinner or before bed and expect to sleep. And if you’re drinking sodas, coffee, or iced tea all day, it’ll still disrupt your sleep. I tell patients to limit caffeine consumption to under 250 – 300mg a day. As a guide, an 8oz cup of coffee has about 100mg caffeine, the same amount of tea has 24mg, a 12oz can of soda has 34mg, and those gnarly energy shots have 200mg of caffeine! I strongly advise against consuming caffeine after lunch if you plan on a bedtime between 10pm and midnight.
Rule 4: No naps! Boo! Hiss! Why is it that as kids, just the word nap sent us into a tizzy tantrum, but as adults we love naps? If anyone has an answer, please let me know. Anyway, as satisfying as it is, napping disrupts your sleep-wake cycle, temporarily resetting it to where you’re not likely to be able to go to bed between 10pm and midnight. Bummer.
Rule 5: Melatonin. I recommend 2 to 4mg of melatonin at bedtime; it really seems to help a lot of my patients. I do find that some patients get daytime hangover from it though, so you’ll have to see where you fall on that one. But it’s definitely worth a shot if you’re suffering from insomnia.
Rule 6: Get up at the same time every day, and go to bed at the same time every day. Yeah, it’s kind of a drag not sleeping in on weekends, but a sleep routine can make a big difference in your relationship with Mr. Sandman. You can’t regulate when you’ll fall asleep, but you can regulate when you wake up. So set your alarm and get up at the same time every day, no matter how tired you are. Don’t nap and go to sleep between 10pm and midnight, and you should fall asleep. If sleep still eludes you, stick to the same plan, and you should surely sleep the second night. You can’t decide when you’ll fall asleep at night, but you can regulate your sleep-wake cycle by deciding when you wake up. Stick to setting your alarm for the same time every day, and hopefully your brain will get the idea.
Rule 7: I recommend taking a glycine or magnesium supplement at night as well as L-theanine and lavender. They don’t make lavender teas, pillow sprays, lotions, and sachets for nothing. I have heard from people that swear by lavender as part of their wind down routine before bed. You can find these supplements on Amazon.com. Shameless plug: handily enough, you can also find my book, Tales from the Couch for sale there too. Check it out.
Rule 8: This is the Mac Daddy, numero uno, absolute, not-to-be-broken rule. Alcohol. If you consume alcohol before sleep, you will not sleep. Why? As the body metabolizes the alcohol, it goes into a withdrawl-like reaction and disrupts sleep. I know what you’re thinking. You’re thinking that a little nightcap helps you sleep. Wrong. Some people will tell you differently, but trust me…alcohol and sleep do not play well together.
Rule 9: A comfortable bedroom. Your bedroom should be an oasis of calm serenity. There should be no office or desk in the bedroom. It should be uncluttered. Anything not conducive to sleep should be out. Make sure it’s dark and quiet at bedtime. The weight of multiple blankets can help sleep. You can even purchase weighted blankets expressly for this purpose. The weight is comforting and relaxing to the body.
Rule 10: This sort of goes hand in hand with #9 above. Try a low temperature in the bedroom. I personally make sure my bedroom is at 70 degrees. The blankets from rule number 9 come into play here too. There’s something very comforting about burrowing under fluffy blankets to go to sleep. I mean, they’re called comforters for a good reason.
Rule 10: No eating late at night. People seem to mostly make terrible food choices at night, all in the name of snacks…chips, candies, baked goods. Sugary foods are especially bad. When you eat, the body goes into digestive mode, not sleep mode; it is very interfering to sleep. Sugars especially are no bueno. Evening or night snacking is one of the worst things you can do If you want to sleep.
Rule 11: Relax and clear your mind. There’s an older pop song that has a lyric, Free your mind and the rest will follow. It’s true. We all have problems and stresses throughout the day, and they seem to pop up when your head hits the pillow. You have to come to some resolution on how you’re going to handle the problems in your life and put them to bed so that you can put the rest of you to bed.
Rule 12: Spend money on a comfortable quality mattress. You’re going to spend a third of your life in your bed. Just suck it up and spend the money on the mattress. Don’t cheap out. Another place to spend money is on good linens. Few things are as inviting as a comfortable mattress covered in minimum 1,000 thread count all-cotton sheets. If you’ve never had nice linens, try them.You can pick them up on a white sale or online. You can thank me later.
Rule 13: No exercising late at night. When you exercise late at night, you raise blood pressure and heart rate, which will hype up the body, which is the antithesis of what you want when it’s time to sleep.
Rule 14: No liquids prior to sleeping. No rocket science here. If you put liquids in, you’re going to need to get liquids out. In other words, you’re going to have to get up in the middle of the night to pee. And you’re probably going to stub your toe. Not good.
This is my handy dandy guide on the do’s and don’ts when it comes to sleep. Anything is better than counting sheep. I don’t know who came up with that, but I would like to inform them that I have never in 30 years heard of it working. I’ve never before wanted people to fall asleep as a result of reading something I wrote, so this is a first! I hope you’ve learned some things here that will put you out like a light.
