Losing weight on a low carb diet is easier than losing weight on a low calorie diet, because you’ll have more constant energy and you’ll have fewer cravings. The less carbohydrate calories you eat, the less hungry you will be. The fewer calories you eat, the faster you will lose weight. The less protein you eat, the fewer sweet and starch cravings you will experience. The most important determinant in how much you weigh, in the long run, is your carbohydrate intake.
