Dieting, Making It Work For You
By Dr. Nina C. Franklin on October 13, 2012
The myriad of dieting gimmicks floating around in the mainstream media is one of today’s most annoying trends. Most popular dieting programs (i.e. Nutrisytem, Jenny Craig, The Atkins Diet, The Zone Diet) appeal to people’s vanity with claims that promise a substantial amount of weight loss in a given amount of time which leads to Americans spending an estimated $42 billion annually on weight loss foods, products, and services. Unfortunately, dieting for the purpose of good health is rarely, if ever, emphasized. This is primarily because “dieting” isn’t healthy. What’s healthy is a good diet. The term “dieting” describes the act of restricting calories (i.e. low/very low calorie dieting) or certain nutrients (i.e. no/low carb dieting) for the purpose of weight loss and is not to be confused with the term “diet” which simply refers to habitual eating patterns. Individuals who consume a diet rich in high-fiber whole grains, vegetables, fruits, and low-fat dairy, moderate in lean protein, and low in fat will inhibit weight gain and improve their overall health, in the long-term. As such, a good diet should be the focus of any weight loss program.
Research shows that 1 out of every 3 adults in the United States is trying to lose weight yet nearly 70% of American adults are overweight or obese suggesting that the popularized dieting programs are not working. Why aren’t they working? Well, it’s primarily due to a lack of compliance. Dieting programs that promote weight loss with calorie or nutrient restriction are problematic because they require dramatic alterations in habitual eating patterns that lead to an inability to fully comply in the short-term. This is why over 75% of individuals who resolve to lose weight each year abandon their weight loss programs by the end of January. Furthermore, it is quite difficult, if not impossible to restrict calories and/or nutrients in the long-term, which is why 95% of individuals who do lose weight regain it over time.
All dieting programs involve some sort of calorie manipulation. Calories are obtained from food sources (i.e. carbohydrate, fat, protein) and serve as fuel for the body to carry out vital functions like breathing, eating, and sleeping. There are 3,500 calories in one pound of fat; therefore, if 3,500 calories are accumulated within the body over a given period of time, a surplus will occur resulting in a net weight gain of one pound. On the flip side, if 3,500 calories are expended over a given period of time through physical activity, a deficit occurs resulting in a net weight loss of one pound. When the amount of calories consumed from food is equal to the amount of calories expended through physical activity, no weight gain or weight loss occurs, which represents a balancing of calories.
Dieting programs that focus on calorie restriction often promote reduced food intake by encouraging you to consume prepackaged meals, smoothies, shakes, and candy bars with a fixed amount of calories. The latest trend in calorie restriction involves point-counting systems, which are cool because they eliminate the intimidation of 4-figure numbers (i.e. 2,000 calories) by providing you with a simple system that equates to 50 calories per point (but why pay for these when you can use on line calorie trackers for free?). Those dieting programs that involve nutrient restriction tend to focus on reduced intake, or total elimination, of carbohydrates or fats from the diet in order to manipulate metabolic pathways in the body. The problem here is that carbohydrates and fats are key nutrients that the body requires in sufficient quantities for normal functioning; therefore, if these nutrients are withheld, malnourishment is an eventual consequence.
