Many people believe carbohydrates are making their body fat high. So they start working out, and try to loose weight by cutting carbs from their diet. What they may not know is that carbohydrates are the body's main source of energy.
The real problem is eating too many carbs and not burning any of them off.
The trick is to eat healthy carbs such as oats, sweet potatoes, vegetables, and brown rice. When you eat these types of carbs they will give your body energy to workout, as well as heal from previous workouts.
The same energy you use to run, jump and swim, is the same energy you use to synthesize proteins and heal the body.
So if you don't eat any carbs you will have no energy to workout or heal from workouts you do accomplish. Also after you do end up eating carbs, you will binge and gain all your weight back.
So try eating small servings of healthy carbs mentioned above in every meal along with proteins and you will achieve the lean healthy body you desire.
