Bought a Peloton a few weeks ago.
From 25-45, I stayed in pretty good shape but still a little heavy. Ran a lot from 26-30, when I completed my one and only marathon, and haven't really ran since. 30-45 I belonged to gyms and did a little of everything (Insanity, Spin classes, etc).
A couple of years ago when I had cancer, I was on a feeding tube for a couple of months and lost 30lbs. Since then I've gained the weight back plus 10.
For me, it really is all about food/beer. Even when I was training for a marathon and running 30+ miles per week, I wouldn't lose weight unless I didn't eat like a pig.
Besides the feeding tube, which I hope to never do again, IF has probably worked best for me. My best results were 20/4 with zero exercise. I have to think doing 20/4 combined with a little Peloton should produce some good results. I plan on moving that way once I get back from vacation in a few weeks.
