I bet she's a liar of course. But that aside, some people indeed feel starved on a 1500 calorie diet. Take into account, activity level, muscle size, height. I remember stopping my period for months at one point because I got way too lean eating 1600 calories (I mostly weight lift). So rare instances of course. Anyways she'd be very thin eating 1500 calories and expending so much energy...but nope she's a big fat liar and eats probably close to 3000-3300 daily.
