Why am I eating protein but not gaining muscle?

Unfortunately, a protein-centric diet without exercise will not lead to significant muscle growth. Why? Because muscle development is a dynamic of protein synthesis and protein breakdown. If you're not stimulating your muscles through exercise, the synthesis-to-breakdown ratio will not be in favor of growth.

Why am I working out a lot but not gaining muscle?

What is the 20 minute protein rule?

It recommends the consumption of 20g of protein within 20 minutes of exercising. The body is most receptive to amino acids in this period and can optimally utilise them to repair muscle tissue that has been damaged during exercise and maximally stimulate protein synthesis (muscle building).
