Even when the body is in starvation mode, one specific part of the muscle growth system (4E-BP1) becomes more active — which is confusing because other parts are shutting down.

Protein synthesis signaling in skeletal muscle is refractory to whey protein ingestion during a severe energy deficit evoked by prolonged exercise and caloric restriction

Randomized Controlled Trial

Human

2019 Apr

Even when the body is starved of energy, a specific muscle protein (4E-BP1) still gets activated at one spot, even though other muscle-building signals are turned down — showing the body is regulating different parts separately.

Similar Assertions

When you lift weights, a specific protein in your muscles (4E-BP1) temporarily stops being activated in one way, even though another related protein (mTOR) stays just as active as before—this suggests that mTOR might be controlling 4E-BP1 through a different, hidden method.
