You need fat to burn off fat. Even probably the most scorned fattener is really a fat burner. Athletes that avoid fat will soon gain pounds while their muscles get smaller. And no wonder! Essential fatty acids are as important as vitamins. Without them, your body is unable to product fat-burning hormones. Fat isn't just the number of yours one supply of energy; it calms your nerves, builds the cells of yours, makes your skin smooth and younger looking, and cushions your nerves and organs - and with no fat, you wouldn't be able to produce some hormones!
