Why Some People Can Drink Alcohol Without Getting Fat

By Tom Venuto, NSCA-CPT, CSCS

Alcohol has been implicated as a factor that may hurt your efforts to lose body fat. Whether alcohol is "fattening" has been a very controversial subject because technically speaking, alcohol is NOT stored as fat; it is oxidized ahead of other fuels.

Whether moderate drinking is healthy has also been a subject of controversy. Many studies show that cardiovascular health benefits are associated with moderate beer or wine drinking (which has been of particular interest lately with reservatrol in the news so much), while other studies show improved insulin sensitivity. Some experts however, say that alcohol has no place in a fitness lifestyle.

A recent study published in the journal Obesity adds new findings to our knowledge about alcohol, insulin resistance and abdominal obesity. Analysis of the results as compared to other studies also gives us some insights into why some people seem to drink and get fat while others seem to drink and get thin!

The truth about the beer belly phenomenon
This new study, by Ulf Riserus and Erik Inglesson, was based on the Swedish Uppsala Longitudinal cohort. The researchers found that alcohol intake in older men did not improve insulin sensitivity, which contradicted their own hypothesis and numerous previous studies.

They also said there was a very "robust" association between alcohol intake, waist circumference and waist to hip ratio. They pointed out that a high alcohol intake, especially hard liquor, was closely associated with abdominal body fat, not just overall body mass.

Abdominal fat accumulation is not just a cosmetic problem, it can be a serious health risk. Abdominal fat, also known as "android" or "central" obesity, increases the risk for cardiovascular disease, high blood pressure, high blood lipids, glucose intolerance and elevated insulin levels.

Many other studies have also found a link between alcohol intake and abdominal fat, but this too has been controversial. A study that was widely publicized by the BBC in 2003 dismissed the concept of the “beer belly.”
Nevertheless, it looks like there’s some scientific support to it after all (or at least a “liquor belly” according to this newer study).

Hormones may be strongly involved because high alcohol intake has been shown to decrease blood testosterone in men, and also increase cortisol levels, which can lead to visceral fat accumulation.
Why is there so much controversy? Why the discrepancy in research findings about alcohol’s influence on obesity, abdominal fat, and insulin sensitivity?

Well, here’s the real story of why some people don’t get fat when they drink:
A lot of the confusion is because epidemiological research cannot show cause and effect relationships and mistakes can easily be made when drawing associations based on limited data.
With the nature of these longitudinal studies, you have to look at the lifestyle and nature of drinkers in general (or in this study, hard liquor drinkers). Also, the Swedish study focused on older men, so age may have been a factor. You may be more likely to deposit alcohol right on your belly as you get older.

When you hear that alcohol increases belly fat, you also have to look at what else is going on in the life of the drinker, particularly what the rest of a person’s diet looks like, and how alcohol intake affects appetite and eating habits.

Research says that alcohol can mess up your body’s perception of hunger, satiety and fullness. If drinking stimulates additional eating, or adds additional calories that aren’t compensated for and which lead to positive energy balance, then you get fat. You may also get fat in the belly, no thanks to what booze does to hormones.

Another thing that confounds the reports on whether alcohol contributes to weight gain is the fact that the game changes in heavy drinkers. We know that alcohol contains 7.1 calories per gram and these calories always count as part of the energy balance equation… or do they? With chronic excessive alcohol consumption, it's possible that not all of these calories are available for energy. Due to changes in liver function and something called the microsomal ethanol oxidizing system (MEOS), alcoholism may be a real case of where some calories don’t count. Many alcoholics also skip meals and eat less with increasing alcohol consumption.

Alcohol metabolizing pathways notwithstanding, even if binge drinkers, daily drinkers or heavy drinkers consume most of their calories from alcohol, if they eat very little, and remain in a calorie deficit, they will not get fat. Compound this with the hormonal effects and you witness the skinny, but under-nourished, unhealthy and atrophied alcoholic (the person you'd think would be most likely to have a beer belly).

It's the calories that count
The bottom line is, the idea that alcohol just automatically turns into fat or gives you a beer belly is mistaken. It’s true that alcohol suppresses fat oxidation, but mainly, alcohol adds calories into your diet, messes with your hormones and can stimulate appetite, leading to even more calories consumed. That’s where the fat gain comes from.

If you drink in moderation, if you’re aware of the calories in the alcohol, if you're aware of the calories from additional food intake consumed during or after drinking, and if you compensate for all of the above accordingly, you won’t get fat.

Now, with that said, you might be wondering: “You mean I can drink and still lose fat? I just need to keep in a calorie deficit?”
Yes, that's exactly what I mean. But before you rush off to the pub for a cold one, hold that thought for a minute while you consider this first: The empty alcohol calories displace the nutrient dense calories!

When you’re on a fat loss program you have a fairly small “calorie budget”, so you need to give some careful thought to how those calories should be “spent.” For example, if a female is on a 1500 calorie per day diet, does she really want to "spend" 500 of those calories – one third of her intake - for a few alcoholic drinks, and leave only 1000 for health-promoting food, fiber and lean muscle building protein?
I realize some people may answer “yes” to that question, but then again, if some people spent their money as frivolously as they spent their calories, they would be in deep trouble!

To summarize this into some practical, take-home advice, here are 7 of my personal tips for alcohol consumption in the fitness lifestyle:
(1) Don’t drink on a fat loss program. Although you could certainly drink and “get away with it” if you diligently maintained your calorie deficit as noted above, it certainly does not help your fat loss cause or your nutritional status.

(2) Drink in moderation during maintenance. For lifelong weight maintenance and a healthy lifestyle, if you drink, do so in moderation and only occasionally, such as on weekends or when you go out to dine in restaurants. Binge drinking and getting drunk has no place in a fitness lifestyle (not to mention hangovers aren’t very conducive to good workouts).

(3) Don't drink daily. Moderate drinking, including daily drinking, has been associated with cardiovascular health benefits. However, I don’t recommend daily drinking because behaviors repeated daily become habits. Behaviors repeated multiple times daily become strong habits. Habitual drinking may lead to heavier drinking or full-blown addictions and can be hard to stop if you ever need to cut back.

(4) Count the calories. If you decide to have a bottle of beer or a glass of wine or two (or whatever moderation is for you), be sure to account for the alcohol in your daily calorie budget.

(5) Watch your appetite. Don’t let the “munchies” get control of you during or after you drink (Note to chicken wing and nacho-eating men: The correlation to alcohol and body fat is higher in men in almost all the studies. One possible explanation is that men tend to drink and eat, while women may tend to drink instead of eating).

(6) Watch the fatty foods. When drinking, watch the fatty foods in particular. A study by Angelo Tremblay back in 1995 suggested that alcohol and a high fat diet are a combination that favors overfeeding.

(7) Enjoy without guilt. If you choose to drink (moderately and sensibly), then don’t feel guilty about it or beat yourself up afterwards, just enjoy the darn stuff, will you!

Did You Inherit Fat Genes? The Truth About Biology And Body Fat

By Tom Venuto, NSCA-CPT, CSCS


genetics and obesity
"Battle Your Biology? Fat Chance," proclaimed a headline recently in the health section of the New York Post newspaper. Quoting new research and citing psychologists, dietitians and physicians, the article says that more and more evidence proves that your weight is genetically determined, and if you're fat, "it's not your fault." "We've known for a while that genes - more than environment and behavior - explain obesity" argues Dr. James Rosen, an eating disorder specialist and professor at the University of Vermont.

While genetics are definitely a factor, believing you are destined to be overweight for life because you've inherited "fat genes" is the most disempowering and self-defeating attitude you could ever adopt. The only way you’ll lose weight permanently is to accept total responsibility for yourself and acknowledge the fact that you have the power to change, regardless what mother nature has given you to work with.

There's no denying that heredity plays a major role in how difficult it will be for you to lose fat. You inherited a body type, a predetermined number of fat cells, a metabolic rate and body chemistry just as you inherited your eye color and hair color. In the 1930's, Harvard psychologist Dr. William H. Sheldon developed a classification system for these different body types called "somatotyping." While there are no absolutes, Sheldon identified three basic somatotypes: ectomorphs, mesomorphs and endomorphs.

Ectomorphs are the lean, lanky types. They are usually very thin and bony, with fast metabolisms and extremely low body fat. An ectomorph can eat like a horse without gaining an ounce. Mesomorphs are the "genetically gifted." They are lean, muscular and naturally athletic. Mesomorphs lose fat and gain muscle with ease. Endomorphs are the "fat retainers." Characterized by round features, excess body fat and large joints ("big bones"), endomorphs usually have great difficulty in losing body fat. They have slow metabolisms, they are often carbohydrate sensitive, they gain fat quickly if they eat poorly or don't exercise, and they lose fat slowly - even on a healthy diet.

The tendency of endomorphs to store fat easily can be partly attributed to metabolic problems. For example, endomorphs often metabolize carbohydrates inefficiently. Normal people can eat lots of carbohydrates - up to 60% of their total calories - and they still stay lean. Endomorphs produce too much insulin when they eat carbohydrates and this leads to increased fat storage and difficulty in losing existing fat. This condition is known as "insulin resistance" or "Syndrome X."

Scientists claim that the tendency to gain weight easily may also be due to chemical imbalances in the brain that cause people to overeat. Researchers at Johns Hopkins recently announced the discovery a compound called C75 that blocks an appetite-regulating hormone in the hypothalamus. In mice injected with the substance, 30 percent more weight was lost because the drug caused the mice to eat less. More research is planned to develop a similar appetite-suppressing drug for humans. Unlike Xenical, which blocks fat absorption in the intestine, this new drug would affect the brain's chemistry so that people feel full sooner.

genetics and obesity
Many physicians and health professionals consider these metabolic disorders and chemical imbalances as genetically transmitted "diseases" that require medical treatment. "Obesity is a disease and should be treated like one" says Jackie Newgent, spokesperson for the American Dietetic Association . This idea should be viewed with a great deal of suspicion however, because weight loss is potentially the biggest market in the world for drug sales.

According to Justin Gillis, a staff writer for the Washington Post, more than 45 companies worldwide are trying to develop new obesity drugs, and the stakes couldn't be higher. Gillis writes, "In world where a blockbuster drug is worth $1 billion a year in sales, analysts give $5 billion as the low estimate for sales of an important obesity drug. If a company developed a truly safe, effective weight loss drug, and sold it for $3 a day to one quarter of the 97 million American adults estimated to be overweight, sales would exceed $26 billion a year in this country alone."

Basically, what the medical community is trying to tell you is that if you are overweight, it's not your fault; you were born fat, so don't feel guilty - and don't worry, we have a drug that can "cure" you. Sounds like there's an ulterior motive at work here, wouldn't you agree? Before you run to get a prescription for the next "miracle" drug, you'd better wonder whose interests are being served; yours or the pharmaceutical giants.

Besides, drugs can never be the solution if they treat the symptoms and not the cause. Drugs should be considered a last resort for the morbidly obese who have already tried everything else without success and who will face serious health consequences if they don't lose weight. The editors of obesity.com said it best: "Weight loss drugs do not take the place of diet, exercise, patience, and perseverance."

"Dieting can be an uphill battle against your genes." says Post writer Joyce Cohen. Unfortunately, if you're an endomorph, Cohen is right. Losing weight is definitely easier for some people than for others and that doesn't seem fair. But that's the way life is. Life isn't fair. Let's be honest; not everyone is going to become an Olympic Gold medallist, a Mr. America or a fitness model. But don't despair - you are not doomed to live a life of fatness if you don't have "athletic genes."

Obesity is the result of many influences. Genetics is only one of them. Like it or not, the primary cause of obesity is your own behavior. Most of the factors that affect body composition are entirely under your control. These factors include how much you eat, what you eat, when you eat, what type of exercise you do, how frequently you exercise, how long you exercise and how hard you exercise.
If you have the genetic predisposition towards obesity, you can lose fat like everyone else, you're just going to have to work harder and longer at it than other people. "There is a genetic component to weight," Says Dr. Thomas Wadden, a psychologist from Syracuse University, "but no one is destined to be obese. If weight has been a major problem in your family, you may not be able to become as thin as you'd like, but you can lose weight."

If you find losing weight to be a slow and difficult process, the empowering thing to do is to look at it as asset, because overcoming this obstacle will force you to develop discipline, determination and persistence. These traits will carry over to other areas of your life and make you a stronger person all around. Arnold Schwarzennegger said, "Strength does not come from winning. Your struggles develop your strength. When you overcome hardships, that is strength."

The first thing you must do if you want to lose weight or succeed in any area of your life, is to accept complete responsibility for your situation. In a short but powerful little book called "As Man Thinketh," the author James Allen wrote, "circumstances do not make a man, they reveal him." What he meant was that we are not products of our environment or our heredity (our "circumstances"), instead, we products of our own thinking and belief systems.

We create our own circumstances through positive thinking and positive action and we create negative circumstances through negative thinking and lack of action or wrong actions. In other words, we are responsible for where we are, what we have and how our bodies look.

Some people get very angry with me when I tell them this: They say, "Wait a minute. Are you trying to tell me that when bad things happen to me, it’s my own fault? That I brought unemployment, financial hardships, failed relationships, weight gain or even health problems onto myself? Because if that's what you're saying, that's totally unfair!"
Well, my friend, with very few exceptions, (some things really are out of your control) that is exactly what I am saying.

If you refuse to accept the fact that you are 100% responsible for your weight, you will never be successful. When people find themselves in undesirable situations or they aren't getting the results they want, it’s all too easy to make excuses: It's my genetics, I have big bones, I have a slow metabolism, I don't have enough time to exercise, etc. etc., etc. Making excuses is relinquishing control. It is conceding that you a victim of circumstances instead of the creator of your circumstances. Stop blaming and start taking responsibility for your life. Take action! Start working out. Eat better. Do something - do anything - but don't just sit there on the couch and curse your chromosomes.

So, are you a frustrated "endomorph?" Do you feel like dieting is an uphill battle against your genes? If your answer is "yes," please don’t just quit and chalk in up to "bad genetics," and don't believe that drugs are the answer either - they're not. Your genetics will largely dictate your athletic ability and how easily you will lose weight. That doesn't mean you can't get lean; it only means that you're going to have to adjust your diet and training to fit your body type and you may have to work harder and be more persistent than the "genetically lucky" ones.
Maybe obesity really should be classified as a genetically inherited "disease." But frankly, if you have a "disease" that forces you to learn more about exercise and nutrition, to eat nutritious foods, to adopt a healthier lifestyle, to develop a strong work ethic and to become a more persistent person, that sounds like a blessing in disguise to me.
