If you’re following a low calorie, high carbohydrate diet – you’ll be ravenous, and you’ll lose weight more slowly than if you’re following a low calorie, low carbohydrate diet. When it’s been studied, you lose weight twice as fast on 1500 calories of protein and fat, compared to weight loss on 1500 calories of carbohydrate. The less carbohydrate you eat, the less hungry you will be, and the faster you will lose weight.
