I ended on reddit, damn, but for 2 years I just lurk from time to time, never vote/comment/post

It takes a long time to lose weight, and it’s about 80% diet and 20% exercise. But after a few weeks your heart/breathing should already be better. I’m 55 and wen I started jogging I was without breath and heart in top after 400 yards. Now I can run 2 or 3 miles non stop without too much suffering :)
