I am disguisting fat body. My weight has been all over the place in the last two years. First I went from 220 pounds to 140 in the course of three months because I was depressed and rarely wanted to eat, along with giving up sugary drinks and only drinking water. I got a girlfriend and it's vastly improved my quality of life and I've started eating too much and went back to soda, now I'm back up to 180 and it doesn't feel or look good. I've been off soda again for about a month, so there's that.

The college I go to throws in a free membership to their gym with tuition, it's really new and nice, I plan to start going there but I'm ignorant of proper nutrition or fitness. My body hardly ever eats anything that isn't extremely processed frozen foods or fast food. I need advice on where to start, my life needs a drastic overhaul. I'll be going to college with 15-18 hours a semester while also working 25-30 hours a week at my job so time will be a little tight but I'm ready to do whatever it takes.
