The Claim
In adults with metabolic dysfunction-associated steatotic liver disease (MASLD) undergoing 30% caloric restriction for 4 weeks, consuming 1.5 g·kg−1·day−1 of whey protein does not consistently enhance improvements in muscle strength or endurance beyond those achieved with resistance training alone.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
For adults with MASLD who are reducing calories by 30% for four weeks, taking 1.5 grams of whey protein per kilogram of body weight daily does not produce greater improvements in muscle strength or endurance than resistance training alone.
See the scientific wording
In adults with metabolic dysfunction-associated steatotic liver disease (MASLD) undergoing 30% caloric restriction for 4 weeks, consuming 1.5 g·kg−1·day−1 of whey protein does not consistently enhance improvements in muscle strength or endurance beyond those achieved with resistance training alone.
When muscles are repeatedly stressed during strength training, nerves send stronger signals to muscle fibers, making them contract more forcefully and efficiently. This happens even when the body is burning more calories than it takes in, and adding extra protein does not make this process any stronger.
What the research says
1 studyFor people with fatty liver on a low-calorie diet, doing weight training alone improved muscle strength just as much as doing weight training plus extra whey protein. So, the protein powder didn’t help them get stronger or more enduring than training by itself.
