Good for you man. You just gotta make sure you stick to it. Cleaning all the junk food out of the house is very helpful in that aspect. You'll be amazed at how much better you feel just by changing your diet and drinking a ton of water.
I packed on 40 pounds since my back injury. I'm just now starting to clean up my diet, etc. Aiming to get back down to 215 myself. There's nothing positive about being overweight. There are infinite benefits that you will experience every day to being in shape.
Watch yourself. I'll light you up.
