In his book, Why Diet and Exercise Fail, author Daniel Korn examines the myths of fat loss and attempts to uncover the true reasons why obesity rates in America are at epidemic proportions.
Korn questions current theories and beliefs about weight loss and cites many scientific studies to support his ideas that these concepts are actually wrong. Additionally he puts forward some interesting and unconventional hypothesis as to what are the true causes of stubborn weight gain.
Why Diet and Exercise Fail Basics
Why Diet and Exercise Fail is not a weight loss program in the traditional sense but rather is an exploration of the reasons why modern Americans have so much difficulty losing weight.
The book includes three sections.
Part I: Rethinking Conventional Wisdom
Korn observes the eating and lifestyle behaviors of different cultures and notes that while some cultures eat a diet that goes against conventional weight loss recommendations, they remain slim and healthy.
For example, people in Thailand consume 80% of their calories from white rice, a refined carbohydrate, yet remain free of obesity and chronic disease. The French consume higher levels of saturated fat than Americans but the prevalence of obesity is 70% less. In this way, Korn systematically aims to bring into question common theories or myths of weight loss by providing examples where they don’t apply.
Part II: Current Weight Loss Research
This section explores the current theories in relation to weight loss and provides information about the side effects of various common drugs and how they affect weight gain.
Part III: A New Theory of Weight Loss
Korn outlines new theories about factors he proposes to be the true causes of stubborn weight gain. He proposes that the biggest things influencing weight gain are caffeine intake and sleep deprivation. He also makes the point that they go hand in hand because a high intake of caffeine causes insomnia, which then causes more caffeine intake because you are feeling tired due to lack of sleep.
Other elements he believes play an important role in the modern obesity epidemic include food additives, soda (including diet soda), toxins and refined foods.
In an attempt to address the situation Why Diet and Exercise Fail does not prescribe a specific diet but does make some general recommendations. Korn suggests eliminating caffeine, emphasizing high-nutrient, preferably organic foods and ensuring the intake of essential omega 3 fats is adequate.
Organic fruit and vegetables, whole grains, grass-fed meat, free-range chicken, wild fish, organic dairy products, rice bran oil, wheat germ oil.
Sample Diet Plan
Oatmeal with fresh fruit and organic yogurt
Handful of walnuts
Why Diet and Exercise Fail challenges the idea that exercise is of major importance for weight loss and supports this theory with scientific research.
Korn states that, “The President’s Council on Physical Fitness found that exercise has a very small effect on weight loss. If exercise was a cure for obesity we would expect that exercise would have a more significant impact on weight loss.”
