First time on myfitnesspal

Hi, and welcome!

This tends to be a very helpful Community, in general . . . but it helps us help you if you can post specific questions.

Other than that, I think this post is the best single on-ramp to using MFP successfully, so maybe read it, if you haven't:

Don't let the joke-y clickbait title put you off: It's sensible, solid information.

Wishing you success here!
