For many beginners who want to lose weight they think that the less they eat, the better. NOT TRUE. Starving yourself is NOT the answer, you need to eat the right amount. I know you are in a hurry to lose the fat but you spent years adding the fat, you cant lose it overnight. Many beginners end up on a starvation diet which lowers their metabolism and can start burning muscle.
So how do you know how much you should eat? I know I sound like a broken record but use my calorie calculator! Its easy, in 20 seconds you can tell exactly how many calories your body burns off in a day and how much you should cut your intake so you will lose fat at the optimal rate. A 20% caloric reduction is a very good compromise between speed of fat loss and retaining muscle.
