Why am I craving fruit?

For the last three weeks or so my desire for fruit has been stronger than ever. I know I’m not pregnant so it can’t be that. The only things that have changed for me are that I’ve been doing a better job of eating well (instead of splurging like once a week on junk I’m not cheating at all), and also my boyfriend broke up with me a little over three weeks ago. I’m not sure that has any connection but I wasn’t craving fruit pre-dumping. I wouldn’t say I’m going too crazy eating it, I’m just curious as to why my appetite for it has heightened so much. It just tastes amazing lately! I take a multivitamin everyday as well as workout for at least an hour. I am 5’1 and weigh 116 pounds in case that matters
