Back (again - kinda) :)
Ok, so I've been in and out of MFP for a long time - mainly because I don't 'get' the whole calories in / out thing. I work out 3-4 times a week, with calorie losses of 400-700 calories per workout. I'm 5'6, 145 and want to get back down to 130. I can't make it work! I can't get it through my head what I should start with…
