So, is it possible to top diet pills as a method of losing weight? To be honest, not having ever taken any, I can’t speak from personal experience, but I can’t help being sceptical about most pills, at least those with dubious claims such as ‘watch the pounds melt away’. If they raise your metabolism, and you eat more healthily whilst exercising, then perhaps they can help you to hit your ideal weight - other than that, make sure you research before purchasing.
