I'm not very experienced in dieting and I can't really set the right amount of the small portions of food I should eat 6 or 7 times a day. I'm 6'2 , 170lbs (183, 77 kgs) , and for one portion I ate one skinless chicken breast, is one average sized skinless chicken breast too much for one meal. How should I know how much lbs or grams of meat or food to eat on one meal.
