what it claims

You should stop focusing on weight loss (fat) and prioritize the development of muscle mass, which is described as an essential metabolic organ for health and longevity.

The assertion that muscle is an active endocrine and metabolic organ is widely supported by scientific research (meta-analyses on myokines, published in journals such as 'Nature Reviews Endocrinology'). Muscle indeed plays a key role in insulin sensitivity and glucose metabolism, which is validated by numerous observational and clinical studies. The concept of 'Muscle-Centric Medicine' rightly highlights that caloric restriction alone can lead to sarcopenia (muscle loss), particularly in the elderly, a phenomenon documented by randomized controlled trials (RCTs). However, presenting fat loss as secondary or disconnected from metabolic health is a nuanced view: excess adipose tissue, particularly visceral fat, remains a major inflammatory risk factor. Therefore, the idea regarding the protective role of muscle is scientifically robust, but the 'fat vs. muscle' contrast here is a rhetorical simplification intended to encourage muscle strengthening. It is not a matter of denying the impact of adiposity, but rather of rebalancing the priority toward body composition rather than a simple number on the scale.

What the graded evidence says

Evidence
B

Linked to, not proven to cause.

Effect
all-cause mortality by muscle strength (grip) and by muscle mass vs strength — grip strength: HR 1.16 (95% CI 1.12-1.20) per 5-kg lower grip, 42 cohorts, ~3M people; low muscle strength independently ~2x mortality odds regardless of muscle mass
Measured on
community-dwelling and older adults

What’s uncertain

This is an association from observational studies, not proof that adding muscle causes longer life. Strength is a stronger predictor of survival than muscle mass by itself.
