For some people, at some times, a low-carb diet may really be the answer, at least in the beginning. The reason low-carb diets work is that your body normally uses carbs as a first fuel. When you give your body no carbs (the "induction" phase of most low-carb diets), your body needs to use something for fuel, and so turns to burning your own fat. These diets have proven very successful for many people, but should be undertaken with care as people do need some carbs in their diet. Most low-carb diets nowadays move from an induction phase into a much healthier maintenance phase, where "smart carbs" (high-fiber, lower-calorie choices) are reintroduced. Curb your late night snacking if you want to see good results in your diet and weight loss plan. Eating close to bed time puts calories in your system that will be burned off during your sleeping hours when metabolism slows to a crawl and your calories burned per hour are at their lowest levels.
