Dieting does not lead to obesity or an eating disorder. Over-eating leads to obesity, and eating disorders are a result of mental illness. He didn't say she was on any unhealthy crash or fad diet. It's entirely possible she's simply altering her diet to contain a healthy amount of daily calories and watching what she eats.

Restricting what she eats to an extreme level (which most girls do, especially when they're young, by the way) is what will lead to weight gain and obesity. I speak from experience; I did restrict my eating so much that I ended up gaining weight in the long run. How is that possible? When your brain is starved of that many calories, it goes into panic mode and slows your metabolism to a ridiculous rate. Your metabolism's speed won't change immediately after stopping the diet, which is what leads to weight gain. Dieting like that can also lead to problems with impulse control. Food for thought: women should NOT be eating less than 1300 calories a day. Men should, at bare minimum, be eating slightly more than that (about 1500 calories a day). Next time you try to correct someone, know all your facts, not just some.

And where exactly does it say she's practicing extreme calorie cutting? It's completely healthy to take stock of where all your calories are coming from if you're in the process of changing your diet to something more healthy. Unless you're a doctor or a dietitian, you have absolutely no right to give out dieting advice simply because you've discovered something anyone with the ability to do an internet search can easily find. Just because you had problems with impulse control while on an unhealthy diet does not mean that everyone trying to alter their diet to something more healthy for the long run is going to have the same issue.

I didn't say "all" girls have that problem. I know they don't. Take the stick out of your ass; I didn't look any of that up. It was told to me by my doctor, so yes I have every right to give my two cents. Don't like it? Deal with it anyhow. It's perfectly good advice. Advice, by the way, isn't something that needs to be taken; OP or anyone else for that matter can choose to take it or not. Finally, yes, it's alright to monitor caloric intake when getting used to a new/switching to a new diet. However, one teaspoon (or tablespoon, since there was conflicting information given) of semen shouldn't be avoided purely for the sake of a diet. If she doesn't like to swallow, that's one thing, but if it's the 9 calories (an educated guess) she's worried about, she has an issue. You missed my point entirely.
