I'm 57 and 5'5. I've lost a stone in 8 months- from 9.3 to 8.3 through intermittent fasting and moderate exercise. With me, as long as I don't feel I'm depriving myself that's when i do better.
Every day I buy the smallest bar of chocolate you can get- a couple of mouthfuls. I don't stock up or I'll eat it all. So when I've finished dinner and want something sweet I have that with some fruit. It hasn't affected my weight and I don't feel hard done by.
Just wanted to share as it's works for me.
