Diets Make People Fatter
With each diet, the body will defend itself by fighting against restriction and weight loss for its own survival. As will be discussed in later sections, our physiology has been programmed through evolution and adaptation to respond to times of famine in ways that maximize species survival. Our bodies are wired to fight against weight loss! Each time the body defends itself against a diet, it becomes more efficient at storing fat. Studies have repeatedly revealed that compared to their non-dieting counterparts, dieters are more likely to gain weight in the long run. In fact, David Garner, an eating disorder specialist, has explained that the best way to gain weight is to go on a diet to lose weight!
Weight Cycling and Disease
The common response to a failed diet is to begin yet another weight loss plan, moving the dieter into a weight cycling paradigm. Along with the emotional toll of losing and regaining weight are the physical risks associated with yo-yo dieting. Glen Gaesser, author of Big Fat Lies: The Truth about Your Weight and Your Health, points out that the vast majority of dieters, whose weight fluctuates considerably through their adult lives, have a greater risk of health problems. For example, the risk for cardiovascular disease and type 2 diabetes increased for yo-yo dieters as compared to their non-dieting counterparts, who maintained higher but steady weights.
Dieting poses serious physical consequences, but it also contributes to psychological problems. The effects of caloric restriction include depression, fatigue, fatigue, irritability, social withdrawal, and reduced sex drive. Debra Waterhouse, dietician and author of Why Women Need Chocolate, notes the physiological effects of dieting that can lead to emotional sequences. She explains that dieting causes brain turbulence by reducing brain chemicals and brain sugar supplies, which results in increased food cravings and depressed mood. Dieting decrees serotonin levels, which are needed in order to maintain a calm and stable mood. Studies of adults have found that the more diets women had been on, the more severe their depressed symptoms were. Dieters score higher on measurements of stress and depression compared to non-dieters. Dieting affects a person's emotional life negatively and inhibits a positive connection between mind, body, and spirit.
