During your workout you saw a fellow gym-goer for the first time in several weeks. You hear her telling another member about her recent weight loss. “I swear, the ketogenic diet is the best thing ever. I dropped 10 pounds in four weeks,” she raved.

The next day in the break room, one of your co-workers is incessantly chatting about the meal plan she’s been following for a few weeks, because she’s already lost five pounds.

Intrigued and curious, you try these diets too. But, when you try them, they just don’t seem to produce the same holy crap I’ve found “the one” experiences as the women who sing their praises.
