The Claim

In sedentary adults, four weeks of resistance exercise alone reduces circulating free fatty acids, whereas four weeks of resistance exercise combined with whey protein supplementation at 1.5 g/kg body weight per day does not reduce circulating free fatty acids, indicating that whey protein supplementation suppresses fat mobilization during recovery.

How it works
1 study reviewed
In plain English

In sedentary adults, four weeks of resistance training alone lowers levels of free fatty acids in the blood, but adding daily whey protein supplementation at 1.5 grams per kilogram of body weight prevents this reduction.

See the scientific wording

In sedentary adults, resistance exercise alone for four weeks reduces circulating free fatty acids, while resistance exercise combined with whey protein supplementation at 1.5 g/kg body weight per day does not, suggesting that protein intake may alter fat metabolism during recovery by suppressing fat mobilization.

Why this might work

When someone lifts weights and drinks whey protein, the protein signals muscles to grow by turning on a pathway that builds muscle and stops fat from being broken down. This causes the body to use less fat for energy, so fat levels in the blood don’t drop like they do when only lifting weights without extra protein.

  1. Study: Correlation between physiological and biochemical variables during short term adequate protein intake combined with resistance exercise in sedentary adults

    When sedentary people lift weights without extra protein, their bodies burn more fat, shown by lower fat levels in the blood. But when they take a lot of whey protein while lifting, those fat levels don’t drop — meaning the protein might tell the body to stop breaking down fat and instead build muscle.
