I thought carbs help me, why are so many people on this low/no carb diet?
A low/no carb diet is not appropriate for extremely active people. If you train and or compete on a regular basis you will begin to feel an energy loss if you restrict your carbohydrate intake. A low/no carb diet is most appropriate for inactive or sedentary people who would normally not use the energy that is provided by foods high in carbohydrates. Dieters really have to look closely at what they are consuming for carbohydrates. With the low carb diet at its peak in 2004, many people were indeed losing weight. But, remember, sugar is a carbohydrate. Sugar turns to fat when the body does not burn it for energy. Case in point: The capsizing of Krispy Kreme.
