Yo. My girlfriend is new to the dieting game and recently decided to track her calories in an attempt to lose a few pounds. It's been about 3 weeks, and she's telling me now that she's been experiencing mood swings for a couple of days, possibly PMS-related. She's wondering if the dieting might have had something to do with the more powerful swings. She hasn't yet managed to track down a scale to measure her progress, so I can't say much about that (I'm also pretty observationally inept). She's trying to keep under 2000 calories daily, and usually sits somewhere between 1700-1900 per day. I know she's been keeping her protein up at the expense of her carbs and fat, so that might have something to do with it too. I don't understand much about women, and in assuming this extended to physiology and hormone fluctuations, I figured I could bring the question here. Let me know if any more relevant information is required. No you can't have pics.
