Why all diets fail

Why all diets fail
Excerpt from Dr. Max Sawaf’s new book "Anti-Aging Made Simple"
More than one half of the Western population is trying to lose weight. After more than 2000 diet books and 1500 different diets the world epidemic of obesity is spreading like fire. People are tired of dieting, depressed about their failures and totally confused with thousands of conflicting messages from experts who do not seem to agree on anything, except that you should eat less and exercise more. In order to understand why diets fail you need to understand a little bit how your metabolism work. The term basic metabolic rate refers to how much your body burns when you are asleep or sitting behind a desk or a TV screen, which is the majority of your time. A small change in metabolism has a huge impact on your weight. Someone who eats a lot and does not gain weight has a higher metabolism than someone who eats very little but gains weight. Genetics play a certain role. How active or lazy your thyroid gland also plays a role. But the biggest role by far is how much muscle you have. Fat is very light in weight…Think of it like snow. One kilogram of fat fills more than a two liter bottle of Coke but burns only five calories per day. One kilogram of muscle is half that size and burns 100 calories per day. The truth is that all diets succeed in the first few weeks for various reasons. But they all fail for the same reason: more than half of the weight loss in most diets is loss of water and muscle, which will slow down your metabolism. Stop obsessing with your scale, kilograms and weight and think more about your muscles, your belt and the size of your waist in terms of inches or centimetres. The danger of all diets especially when they are not balanced, in terms of providing enough protein, is that you end up losing so much muscle that when you eventually stop dieting, and all dieters eventually get tired of dieting, the same amount of food will make you gain even more weight since your metabolism is now slower creating what we call the yo-yo dieting.
