Any [emphasis added] weight loss pill

Nope. There's one that actually works really well. It's called 2,4-dinitrophenol. It works by fucking up the way that your body makes/uses ATP; instead of being available for cellular respiration, it gets wasted as heat. It's like constantly doing cardio; you're burning tons of calories without doing anything. Users have reported losing up to seven pounds of fat--not water--in a week. The downside is that this heat can lead to hyperthermia if you take too much, and since the half-life is quite long, by the time you start seeing the negative side effects from OD'ing--about a week after you OD--it's way to late, and your brain cooks. Oh, and you're gonna sweat like a watermelon at a Baptist barbecue the whole time.

It was thought that it also caused cataracts, but that seems to have been incorrect.

It's been banned since the 40s, I think, as a diet pill, because people had a tendency to take too much and die. If you know where to look, you can still find it. I wouldn't recommend it for the overwhelming majority of people though.

I tried one if those weight loss food systems once. I'll say it's not really a scam, but if you knew what you were doing, you could do better.

They basically controlled what you could eat so that you ultimately consumed less calories so you could lose weight without having to count calories, or manage macronutrients. But it was also expensive and the food was terrible, and as you said, as soon as you get off of it, you go back to the way you were. ****

However, I do have to thank it for opening my eyes and helping me understand calories and macros a whole lot better. Not to mention proving to me that I could in fact lose weight, back when I thought it was just the way I'd be forever. Because then I started looking into why it worked and what I needed to do to stop buying that crap and eat real food again.
