Hi and welcome. That was going to be my question/comment: whether or not you were experiencing any hormonal weirdness yet. Once I turned 40, crap hit the fan. Big time body changes, despite not really changing much about my eating (I've been LC since I was 28.) My periods started getting further apart, thinning hair, different body fat distribution... bleh!

I don't have any particular advice except maybe to start a journal here or elsewhere, and just keep track of what you're eating and doing, even if you're not weighing and measuring. Others can pop in and share their thoughts, and it's handy if you want to try to go back and connect some dots later on.

Best of luck.
