who are tweaking anything (and everything) related to their bodies.
The first: those coveting weight loss. This is the largest contingent and the reason why damn near all health writing is geared toward weight loss.
The second: those trying to perfect themselves just ’cause. Some get off maximizing their minds, some get off maximizing their bodies. Both are worthy undertakings.
The third: those aiming to correct some underlying issue(s) unrelated to weight. This group is often mistaken for the second, even as there are far more participants in this one. Thus, if you observe some ostensibly fit person measuring out iron/phosphate ratios and organizing bags of supplements, it’s at least 70/30 that this individual is suffering in ways superficial appearance betrays.
