27M.  I lost 15 lbs of fat since June, which took me down to about 19% bodyfat and a BMI of 23. I quit smoking almost 4 months ago. I've been lifting and have gained a few lbs of muscle.  I got bloodwork done and everything came out textbook.  I've never felt better in my life. If I were obese, I might as well not have made any of the positive changes.
