The Claim
Skeletal muscle hypothyroidism during weight regain impairs muscle regeneration by suppressing the transition of satellite cells from proliferation to differentiation, leading to delayed or incomplete recovery of muscle mass.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When thyroid hormone levels are low in skeletal muscle during weight regain, satellite cells fail to shift from multiplying to maturing, resulting in slower or incomplete restoration of muscle mass.
See the scientific wording
Skeletal muscle hypothyroidism during weight regain may impair muscle regeneration by suppressing the transition of satellite cells from proliferation to differentiation, contributing to delayed or incomplete recovery of muscle mass.
After weight loss, muscle tissue becomes less responsive to thyroid hormone, which keeps muscle repair cells stuck in a growing phase instead of turning into mature muscle fibers. This prevents muscle from regaining its mass, while excess energy gets stored as fat instead.
What the research says
1 studyAfter losing weight, your muscles may become less responsive to thyroid hormones, which are needed to help repair and rebuild muscle. This makes it harder for your body to regain muscle even if you eat enough protein, leading to more fat gain instead.
