It is used to determine the nutritional efficiency of protein in the diet, [ 1]: 11 that is, it is used as a measure of "protein quality" for human nutritional purposes. [ 2]
A good rule of thumb is to eat 0.55-1 g of protein per pound of body weight if your goal is to lose weight. Athletes and heavy exercisers may require even more protein. Work with a registered ...

But both of the experts WH spoke with agreed that within two hours is optimal. “Don't go longer than two hours, and if you have big goals for gaining muscle and repairing muscle, get it closer ...
Biological value. Biological value (BV) is a measure of the proportion of absorbed protein from a food which becomes incorporated into the proteins of the organism's body. It captures how readily the digested protein can be used in protein synthesis in the cells of the organism. Proteins are the major source of nitrogen in food.
Final Thoughts. Protein powders are a convenient way to up your protein intake. But if you’re using protein powder to lose weight, it can backfire and lead to weight gain if you don’t make ...

A leucine intake of at least 3g per meal, achieved through 25-30g of high-quality protein, is necessary for effective muscle protein synthesis. [ 168 ] Data from the National Health and Nutrition Examination Survey III indicates that the average protein intake among the elderly is 0.9g/kg of body weight per day, with half of this intake ...
