I kind of did the same thing. I put on about 10 pounds freshman year of college and I decided to eat a little healthier this summer. I lost about 15 pounds(now I only weigh 150, so I need to bulk up some, I went from being pudgy to being scrawny, but I'll worry about that when I get back to college and have gym access. I basically cut out soft drinks(I have like one a week maybe), and tried to get something healthier when I go get lunch after work. I was running for about 2 months, but I got my wisdom teeth off and had to take a week off and haven't started back. But I haven't put on any weight since I quit running, and it doesn't really bug me because I don't want to lose any more.
