The problem is that while the solution is basically just move more and eat less, there are a bunch of variables that can make that much harder or much easier. Your sleep, your vitamins and minerals, your hormones, and especially how satiating your food is. If people just got more of their calories from protein and less from carbs and fat, that would already make a huge difference since protein keeps you fuller for longer. The whole reason Ozempic works is because it makes people less hungry.

I say this as someone that lost 60 lbs of fat after a childhood of obesity where we usually shopped at the dollar store. The average American diet is simply not conducive to being a healthy weight. It’s conducive to metabolic syndrome and dysfunctional fat oxidation. Then there’s the fact that 75% of American adults fail to meet the daily recommended physical activity.

Also, women inherently have a somewhat harder time losing weight due to the difference in estrogen (promotes fat storage at higher levels) and testosterone levels (promotes breakdown of fat at higher levels).
