Why Dieting Can Make Us Fat

Since we are a nation obsessed by weight loss, it is so important to realize that chronic dieting itself can make some people overweight or obese as a result. There are many reasons why our bodies resist weight loss and more than likely it is due to a fear of starvation. This involves the neuro-endocrine system and we have many mechanisms to prevent this threat to our existence.

This is more than likely involving our set -points defined as “a level at which body fat or body weight seems to resist change despite changes in energy intake or output.” The set point for each of us is largely determined by genes. Signals related to food intake affect hunger and satiety (feeling of fullness) over short time periods while signals from the adipose tissue trigger the brain to adjust to both food intake and energy expenditure for long-term regulation. The  two primary hormones involved are ghrelin and leptin. Ghrelin is a peptide hormone produced  by the stomach that stimulates food intake and leptin is a peptide hormone produced by fat cells that signals information about the amount of body fat. The interactions are complex and better left to more academic discussions than in this blog post.

If you diet frequently, you should understand some of the implications of these interactions. The following article is a long read but it is important to know the facts – the best action is to prevent weight gain if possible so that we do not have to deal with its effects later on.

Weight management is possible by putting into practice the following simple suggestions.

Balance your intake and output, for example, weight yourself once a week; if the number goes up, cut down your calories.

Cut down on calories, e.g. bring your own lunch rather than eating out.

Don’t get too hungry – fill up on high fiber foods.

Increase activity – Take a walk during lunch break or after dinner.

Avoid fad diets – they only lead to the problem.

The Best Advice for Weight Loss

An article from Women’s Health provides sound and simple advice for weight loss that often gets missed or ignored when one follows fad diets. You have probably heard of most of these tried and true suggestions before, but when you put them all together, they just make a lot of good sense. No fads, just the facts based on evidence.

I might add to be aware of portion sizes. Follow the rules of measuring or estimating portions by using your hands: a fist = 1 cup; a cupped hand = 1/2 cup; a meat serving (3 oz) is about the size of your palm; a tablespoon = your thumb and a teaspoon = the tip of your  thumb. There is no need  to weigh foods on a scale. Keeping a food diary or journal is also a helpful idea to increase awareness of what you actually eat each day.

The Obesity Epidemic: Why?

Diet and Health: With key to the calories. Lulu Hunt Peters, 1918

By Sally J. Feltner, PhD, RDN

In 2013, the American Medical Association House of Delegates approved a resolution classifying obesity as “a disease state with multiple pathophysiological aspects requiring a range of interventions.” We now accept the fact that obesity can lead to diabetes, heart disease, and cancer risks.

Today, 2.1 billion people – nearly 30% of the world’s population – are either obese or overweight, according to new data from 188 countries. The U.S. Centers for Disease Control and Prevention analysis said, “About 38 percent of U.S. adults aged 20 and older are obese as are more than 17 percent of children aged 6 to 11, federal data shows.”

“The global problem affects all countries, income levels, age groups and accounts for over 3-4 million deaths a year with estimated health costs of over $2 trillion a year.” (International Journal of Obesity).

There is no one cause. Many people still continue to blame the obese person’s lack of willpower and insist that if they just ate less and moved more, their weight would not be a problem. This may explain some cases of obesity, but how could more than 2 billion people worldwide begin to make poor choices about their food intake and allow themselves to become fat. Moreover, this upward trend earnestly began in the late 1980’s and has continued to the present. Obesity rates were just 13.4% in 1980 but reached 34.3% by 2008. So what happened to cause this sharp rise? – More than likely a lot of things.

In 2016, an article by Bruce Y. Lee, Associate Professor of International Health at Johns Hopkins Bloomberg School of Public Health succinctly describes his opinions on what factors changed to help create this epidemic. He states that obesity is a result of the breakdown of three major systems that include biological, social, and environmental factors.

Biological Systems

Our metabolic systems have been affected to some extent by non-stop dieting. A plethora of fad diets and exercise gimmicks grew into a huge obesity industry. Diet books topped Amazon and best seller lists while the supplement industry went berserk over worthless and sometimes dangerous weight loss aids. Americans responded and when surveyed, a large majority of respondents said they were “on a diet.”

Even TV reality shows (The Biggest Loser) resulted in weight loss that lowered the metabolism of almost all participants gained back their hard-fought  loss. As each weight loss attempt occurs, the cycle of weight loss/regain occurs over and over again. The body is threatened by a perceived starvation state and attempts to prevent it by putting forth metabolic and hormonal mechanisms to alleviate the threat. Obesity research has shown that nearly 95% of dieters regain their weight loss in a few years.

Social Systems

Social media, friends and family, cultural beliefs, TV advertising, and personal responsibility are all important in shaping our behaviors about eating, appearance, and body image.

Advertisements in the media have promoted the obesity epidemic by making claims that their products will magically transform your body into a svelte image and allow you to finally wear that bikini you bought years ago and that weight loss is easy. Most weight loss diets promise success by showing us before and after pictures of supposedly successful weight losers. What they do not say but disclaim in the small print that you usually can’t read is that results don’t always occur as presented. Most weight loss programs do not include an exercise component nor do they offer any behavioral counseling. Almost all have no disclosure about their success rates of weight loss and maintenance.

Environmental Systems

Determining what a healthy diet consists of is difficult enough – opinions abound and debates continue. This results in confusion and misinformation for the average consumer. They tend to give up on just what exactly is the best way to eat.

So many individuals are exposed to reliance on cheap foods found in the fast food industry. They may live in food deserts defined as parts of the country usually found in impoverished areas devoid of easy access to fresh fruit, vegetables, and other healthful whole foods. This is largely due to a lack of grocery stores, farmers’ markets, and other healthy food choices.

The food industry has been instrumental in developing ultra-processed foods that hardly resemble “real” foods. Snacking has become a national pastime and is dominating several of the inner aisles of the supermarkets. Snacks are abundant in every gas station, convenient store, or vending machine that tempt you to increase their profits.

Additionally, the food industry promotes the intake of sugar, fat and salt by attempting to reach what they call “the bliss point,” defined by the precise amount of sweetness that makes food and drink most enjoyable. You can find the results in the sugary cereals and sweetened beverage aisles in the supermarkets.

People do not cook anymore leading to procuring your meals outside the home. Restaurant portions have become gigantic compared to what they were in past decades. For example, a typical serving of theater popcorn was 270 calories (5 cups) in 1970 compared to now that is typically 630 calories (one tub). Some restaurant meals contain as many calories as we need in an entire day. The average U.S. intake increased 455 kcal/day, a 20% increase from 1970 to 2009. (Dr. Stephen Guyenet, The American Diet, 2012). From research studies we have found that the more food that is put in front of people, the more they eat. We now are familiar with the term “supersize” and the concept of “all you can eat buffets.”

The complexities of the obesity epidemic/pandemic are impossible to fully comprehend as well as their need to be “fixed” to reverse or at least slow down the trend. There are some solutions to accomplish this but they will require much cooperation between politics, community, medicine, research, government, and the public.

If America’s obesity trend continues at its current pace, all 50 states could have obesity rates above 44 percent by 2030, according to a new report from Trust for America’s Health and the Robert Wood Johnson Foundation. Although important, we need to stop just focusing on what we eat, but equally important on how we eat to fix what contributed to the epidemic in the first place.

Don’t Diet, Live It

Anyone who has battled a weight problem know what it is like to feel guilty about every bit of food they eat.  They become obsessed with every new diet fad that come along especially those that promise unrealistic results and/or quick fixes. They can resort to eating a single food for days or choose foods that promise fat-burning properties. They follow the latest diet from the last issue of a tabloid from the supermarket. They may lose weight initially for a while, reach a plateau and give up to pursue another ill-fated attempt.  Dieting in itself can promote weight gain since with each attempt, your body adjusts to prevent weight loss.  The following article gives a more common sense and realistic approach.

Dieting Fatigue?

It appears that interest in weight loss is waning. People want to embrace a more positive approach to food, diets and dieting instead of obsessing about weight loss. They are becoming more involved in food and healthy lifestyles instead. This a plus for the concept of Health At Every Size approach.  Good news.
