The average adult only needs about 0.8 grams of protein per kg body weight to stay healthy. To estimate your protein needs, multiply your body weight in pounds by 0.36. For example, a 115 lb (52 kilos) dancer would require about 41 grams of protein a day (115 lb x 0.36 + 41.4 grams of protein).
It is necessary that dancers maintain a standard intake of proteins on a daily basis. Recommended intake for dancers: protein - 15-20 % of total intake, 20% of protein intake should be essential amino acids (Chicken, fish, beef, pork or nonanimal complimentary proteins).
