Most of those symptoms apply to any diet, not just a low carb one. One loses weight on a low carb diet by starving the body of its preferred energy source, carbohydrates in the stomach. Over a two week period, known as induction, the body starts to use its second favorite source of energy: body fat. That transition can be a difficult time. The good news is after that, there are fewer symptoms than a low calorie diet.
