Is the gut microbiome really the magic key to fitness gains?
So I've been hearing all this hype about how the gut microbiome can predict everything about our health and fitness, like it's the holy grail of gains or something. But honestly, the methodology behind these claims is kinda sketchy, right? Lots of studies are based on correlations rather than causation, and sample sizes can be way too small. For example, one study (Zhao et al., 2021) found some links but only had like 50 participants. That's not a solid base to back up claims that gut health is gonna turn me into the next Arnold, bro. Like, I'm all for gut health, but let's not pretend it's the end-all-be-all when I can still hit my PRs with a solid split routine. Anyone else think this gut hype is getting out of hand?
