Combining strategic protein intake with fasting is one of the most powerful tools for body composition, longevity and metabolic health. But not all protein is equal — and the type of protein you consume during and around your fasting window matters enormously.
Collagen-rich proteins, like those found in bone broth, are particularly valuable during fasting protocols. Unlike muscle meat proteins which are high in methionine, bone broth is rich in glycine — which balances methionine, supports glutathione production, preserves lean muscle, and enhances the fasting-mimicking effect.
