From the early age of 12 Jessica Alba decided to modify her diet so she wouldn't follow in the foot steps of her heavily overweight family. She eats a balanced diet and shies away from eating carbs to keep her body in svelte shape for many of her more revealing roles.

Jessica sticks to a diet of lean meats, vegetables, egg whites and cottage cheese, and snacks on dried fruit and frozen yogurt to satisfy her sweet tooth.
