Most diets rarely give you the energy your body requires. When you start low-carb dieting, you should do the opposite. You need to eat to give your body more energy. This will improve your metabolism and make your body work for you. As a way to conserve energy, your metabolism tends to slow down when you are hungry.
When you are starved, the body will work against you. You’ll begin to feel cranky and tired. Also, you will find it hard to concentrate or lose weight.
