@xfaca Never heard of dnp but having just looked it up, I can't quite believe that you'd consider that death trap a viable dieting method.
Rather than Keto, which basically makes fat your primary energy source, so that it naturally burns said fat. This dnp shit just blindly burns carbs and fat out of your body, not for use by your muscles or organs, but just converting it into raw heat.
That's the dumbest, most suicidal method of weight loss I've heard of since liposuction. And I don't even know if that could be called "promoting metabolism" since it's spiritually closer to just hacking off your love handles with a hedge trimmer.
