Prendre de l'acarbose pour lisser la glycémie

what it claims

Take acarbose (200 mg per day) to smooth out post-meal sugar fluctuations and mimic the effects of caloric restriction to optimize longevity.

Acarbose is a molecule that slows the digestion of complex carbohydrates directly in the digestive system, which allows for the highly effective smoothing of post-meal sugar fluctuations. Regarding longevity, the most robust data comes from rigorous animal studies: the National Institute on Aging (NIA) Interventions Testing Program (ITP) has repeatedly demonstrated that this molecule extends the lifespan of rodents. This research suggests it acts in part as a caloric restriction mimetic by reducing the body’s energy assimilation. However, in healthy humans, direct scientific evidence for life extension is lacking. Although meta-analyses confirm its efficacy in stabilizing sugar and fat management, there are no randomized controlled trials (RCTs) evaluating its long-term effects on aging in healthy individuals. Furthermore, its local action frequently causes transient digestive discomfort. Thus, while the stabilizing effect on energy is validated, the transposition of its longevity benefits to humans remains a promising but unproven hypothesis.

Even if every other cause of aging were eliminated, irreversible somatic mutations in neurons and heart cells (which don't regenerate) would still cap median human lifespan at roughly 146-194 years, according to a recent mathematical model.

Strength training has benefits for women beyond aesthetics — it reduces the risk of aging poorly and losing independence.

Not all recovery methods are equal: the fundamental pillars (quality sleep, appropriate training volume, and sufficient nutrition) far outperform trendy gadgets like the cold plunge (which may hinder muscle gain) or the sauna, which are merely secondary bonuses.

Other advice in the Register that leans on the same research.

Regular sauna use (especially dry sauna) is associated with better cardiovascular longevity — but the claim that jumping into cold water right after "undoes" that benefit, or that icing your testicles protects fertility, are untested extrapolations layered on top of a real association.

Dry Finnish sauna is the best-studied form for long-term cardiovascular benefit, at several sessions a week; but the claim that sweating clears microplastics from the body has no source — it's a leap from a study about heavy metals, not microplastics.

There's a real mechanism behind part of this idea — heat trapped by tight underwear affects male fertility — but stretching it into a universal "anti-aging" habit (circulation, inflammation, skin barrier, hormones, deep sleep, for everyone) goes well beyond what the research shows.
