Gotta find exercise that is fun though. Don’t just try one thing and give up, it takes time to find what you enjoy.

I’ve been swimming for 15 years, but only got into bouldering 1.5 years ago. I tried running and cycling but it always felt like a chore so I could not stick with it.

The food problem is much harder to solve for IMO, even shops are designed to get you to impulse-buy junk. Although one minor tip is to do groceries when you’re full, not when you’re hungry.
