Awesome thread.
I got a little too big for myself a little while ago, and began a diet and exercise regimen. I exercise for at least 10 minutes a day (although my average is closer to 30 now), with some of my exercise time spent on cardio and some of it spent on weightlifting.
For a diet plan, I still eat fairly shitty, but I never, never stuff myself. I eat until I'm not hungry, instead of eating until I feel full. My restaurant portions, of say, a cheeseburger (I did stop ordering bacon cheeseburgers) can last me breakfast, lunch, and dinner. I have made substantial, subtle diet changes, and I'm eating more veggies than I used to, but it has been a matter of portion control for the most part.
I was 192 about a month and a half ago when I said "no more," and now I'm 183 and dropping. I'm aiming for about 5 pounds a month. My goal is a long term healthy lifestyle change rather than an actual diet, and I plan on getting down to 160-165, which is my healthy weight (5-7 with a very large frame), and maintaining that shit.
I still don't feel that I look any better at 183 than 192, but meh, I just have to keep going until I see the difference in the mirror.
