The two simple things I did for the last 8 months was:
changing my diet around and walking. really, I cut out a lot of pop and Mc foods and went out for strolls to a coffee shop and did drawing and walk home.
I went from being a 46 to a 34 and 260 to 220. It was really easy.
It only takes a couple of small changes to improve your body. losing weight isn't the hardest thing.
