My problem is I'm not exercising.
I doubt that. Most likely it’s what you’re putting in your mouth. I haven’t exercised at all. Intermittent fasting helps kick you deeper into ketosis. Ketosis helps burn fat. There’s lots and lots of information out there that talks about not exercising to lose weight. Exercise stimulates your appetite so most people eat more which negates weight loss. Fasting improves your metabolism which also helps lose weight.
