The Claim
Obesity reduces the postprandial suppression of muscle protein degradation by 50–70% relative to healthy-weight individuals, leading to sustained amino acid release from muscle during the postprandial period and contributing to reduced net muscle gain.
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.
In people with obesity, muscle continues to break down and release amino acids after eating, whereas in people with healthy weight, this breakdown normally stops after a meal. This persistent breakdown reduces the amount of muscle that can be built after eating.
See the scientific wording
Obesity impairs the postprandial suppression of muscle protein degradation by 50–70% compared to healthy-weight individuals, resulting in sustained amino acid release from muscle despite meal ingestion, which may contribute to reduced net muscle gain.
In obesity, high levels of insulin resistance stop muscles from slowing down their breakdown after eating, so amino acids keep leaking out of muscle tissue even when food is present, which prevents the body from building muscle effectively.
What the research says
1 studyIn people with obesity, their muscles don’t slow down breaking down after eating like they do in healthy-weight people — this means their bodies keep releasing amino acids from muscle even after a meal, making it harder to build muscle. The study proved this happens.
