Lots of protein will help him loose weight at not gain at 128 depending if your in high school . (Amino acids are protein basically,) Foodstuffs that lack essential amino acids are poor sources of protein equivalents, as the body tends to deaminate the amino acids obtained, converting proteins into fats and carbohydrates. Here is what happens when you eat too much protein. Therefore, a balance of essential amino acids is necessary for a high degree of net protein utilization, which is the mass ratio of amino acids converted to proteins to amino acids supplied. Therefore, causing you to not gain weight but be a stronger 128 to 135 lbs. You wanna eat less protein to gain weight with lots of fats and carbohydrates. The weight you gain will be all fat though, but will help you gain muscle with working out when you get to 150lbs then usually you can get as big or as small as 145 as you want. Some people have their own opinions or theorys on workout diets for high schoolers this is mine. Your body does not work as adults do with protein.
