Weight Watchers

Weight Watchers in the 'Greatest Weight Loss Diets of All Time'? Oh, the tales I could tell. Picture this: counting points like they're precious gold nuggets, and that friend who won't shut up about their newfound 'flexibility' while side-eyeing your pizza. It's a cultural icon, the diet version of comfort TV—everyone knows it, everyone's tried it once, and everyone has an opinion. It's like the Marvel Universe of diets—always expanding, always rebooting, and somehow, always there when January rolls around.
