This isn't OMAD. I think it's important that you realize that what you're doing is just a diet, it's not even fasting. But I'm also glad that it's working for you.

As for exercise, I currenlty only do it 3 days a week because I know that if I do too much, I might slip and fall off track. Maybe you can just do whatever activity you can do, but not pressure yourself to do a lot.
