I had a gf that joined a female dance/pilates type gym and went religiously, yet actually gained weight over the year. When I told her that the two scoops of protein powder she was taking at lunch were probably causing weight gain because no girl needs an additional 60 grams of protein on top of a well balanced diet we already had, she got mad. Eventually we broke up because I can't deal with someone that can't have a logical discussion. She's now even heavier, yet still going to that gym years later.
