I find it a little confusing that I can eat day on day off and not lose any weight.
My fast lasts approximately 36 hours each And I have been doing this for three weeks now..

I realize the metabolism probably slows down to some extent, But if this calories in calories out argument holds… Then why, if I am only eating a few days a week am I not losing any weight?

On the days that I do eat, I eat healthy and I try to eat 2,000 calories. No alcohol, of course, and I am a non-smoker.

I am 50 years old.

I walk and cycle everywhere.

What could I be doing wrong to stop me from losing weight?
