Related questions
Questions this research helps answer.
Protein and recomp answer
How much protein do you need for body recomposition?
Protein is one of the most reliable supports for body recomposition, but it is not magic by itself. Training creates the adaptation signal; protein helps support satiety, recovery, and lean-mass retention while calories are managed.
Protein and aging answer
Does protein help preserve muscle as you age?
Protein is a useful floor to protect as you age, but it is not enough by itself. Pair it with resistance training, enough calories for your current goal, and medical guidance when health conditions affect your needs.
