Crypto. Most LLM based AI. 80-90 percent of the startup world after 2009.
Anything related to toxins or detox. Keto and Carnivore diets.
Most online college programs.
Those vibram finger shoes and barefoot running. Most gym memberships; honestly half of the gym bros need to diet more than they need to slam weights and HIIT
Probably ozempic, since people going off it immediately balloon back up
I've wondered for a long time what the long term impacts of aggressive teeth bleaching are on enamel, too, but not sure if I'd call that snake oil; it works entirely as intended
Im 90% sure the case with keto is the same as with ozempic. It is a fairly specilized diet that by coincidence works fairly well for losing weight.
From the little i read its apparently for the same reason osempic works. It leads to loss of apetite.
Keto works, but whether the supposed science behind it is the reason it works, I have no idea.
People say something about ketones and so on, but for me, it's just that eating carbs makes me hangry again soon after I'm done eating them, so I'll want to eat again. Eat less carbs, get less hangry, easier to eat less.
I really like the vibram shoes. They were fine for running, granted you could also get running shoes. But they also work very well for squats and deadlifts. And I do make proper lifting shoes too. But that's already too many pairs of shoes to bring to the gym for me.
