A 5 s search leads to this page from the US gov: https://www.consumer.ftc.gov/articles/truth-behind-weight-lo...
Note that this page warns against weight loss ads — not weight loss, which they argue is a more complicated topic than an ad will convey.
I'm not the one who carries the burden of proof, but I appreciate the sources. Thank you.
> Among patients whose PCPs discussed weight loss, 20.1% achieved ≥ 10% weight loss if they did not perceive judgment by their PCP as compared to 13.5% who perceived judgment.

Most sustainable ways to be healthy are not as easy to monetize as quick "fixes" like pills and shakes. Don't drink sugar or artificially sweetened products (I haven't kept up on the more recent artificial sweeteners, so maybe they're not as bad - idk). Eat more vegetables and less processed food. Get some exercise - even if it's just walking.
It's good for people to understand that beauty comes in all shapes and sizes and that your goal should be whatever size/shape is healthy for you. This is more of a range than an exact size/shape.
So, yeah, shaming, presenting unrealistic goals, selling bs products/fixes, it's mostly all bad, and it's good for people to push back against these ads and the POV's they create.
