How does muscle affect health? in c/health@lemmy.world

Oh, lets see the data to back up your assumptions. Muscle is genetic and highly heritable - https://pmc.ncbi.nlm.nih.gov/articles/PMC4816288/ -- people less genetically blessed can be consistent and still struggle, especially the more they are up against the genetic 8 ball. You are grossly oversimplifying a very complex matter.

Muscle is genetic and highly heritable. (pmc.ncbi.nlm.nih.gov)
 

"Skeletal muscle is a highly heritable quantitative trait, with heritability estimates ranging 30–85% for muscle strength and 50–80% for lean mass. That strong genetic contribution indicates the possibility of using genetic information to individualize treatments for sarcopenia or even aid in prevention strategies through the use of genetic screening prior to the functional limitations."

TIL Muscle directly affects metabolism, glucose uptake, and insulin-sensitivity (www.sciencedirect.com)
 

"As the principal tissue for insulin-stimulated glucose disposal, skeletal muscle is a primary driver of whole-body glycemic control. Skeletal muscle also uniquely responds to muscle contraction or exercise with increased sensitivity to subsequent insulin stimulation. Insulin’s dominating control of glucose metabolism is orchestrated by complex and highly regulated signaling cascades that elicit diverse and unique effects on skeletal muscle."

Muscle is the key. But it is genetic and highly heritable. Some people are born with more, some less. And muscle fiber ratio matters. Some people put on muscle easily and maintain it easily, others not so much. Proper diet, exercise, and lifestyle are vital.
