I am somebody who can exercise a tremendous amount while eating mostly LCHF and not lose, or even gain slowly. This has happened to me while biking 50-70 miles a week, or more recently while swimming 5 miles a week. And all that exercise makes me more hungry! However, the exercise has it's definite benefits for me, a much lower blood pressure and better mood amongst other factors. So I'm not willing to give it up. The only thing that works for me to lose weight is daily IF with once a week 36 hour fast, combined with strict LCHF. It's a daily struggle!
