Hiking, eating correctly, and realizing that I weighed over 300lbs at the age of barely 17. Now I'm 240 (and apparently sexy). I'm going to keep trying until I'm about 220 and then just be happy with it. Keep in mind that 220 is a good weight for me since I'm about 6'3'' and am naturally just a broad, big guy.
I'm telling you, I did NOTHING special. Fuck diets, fuck pills, fuck chronic exercise. If you're patient and you can eat healthy food (and even not healthy stuff in moderation) then you're totally going to be fine.
Go hiking too. Everyone, do it. Best thing in the world.
