The Claim
In obese adult men, postprandial muscle protein gain is reduced by approximately 20% compared to healthy-weight men due to impaired suppression of muscle protein degradation during the first 2 hours after ingestion of a meal containing 26 grams of protein, indicating that obesity disrupts the normal anabolic response to feeding independently of amino acid availability.
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.
Obese adult men experience a 20% smaller increase in muscle protein after eating a meal with 26 grams of protein compared to men of healthy weight, because their bodies do not reduce muscle protein breakdown as effectively during the first two hours after eating.
See the scientific wording
In obese adult men, postprandial muscle protein gain is reduced by approximately 20% compared to healthy-weight men, primarily due to impaired suppression of muscle protein degradation during the first 2 hours after a meal containing 26 grams of protein, suggesting that obesity disrupts the normal anabolic response to feeding independently of amino acid availability.
In obese men, high levels of insulin resistance prevent the muscle from stopping protein breakdown after eating, so even when protein is consumed, the muscle keeps breaking down instead of building up, leading to less net gain. This happens because the muscle doesn't respond properly to insulin, not because there isn't enough protein available.
What the research says
1 studyIn men with obesity, their muscles don’t stop breaking down as much after eating protein like they do in men of healthy weight, so they gain less muscle — even when they get the same amount of protein. The study shows this happens because of how the muscles respond, not because they’re not getting enough nutrients.
