I have lost 47lbs on a calorie restricted diet since February last year. By calorie restriction I mean a 15% cut from my TDEE which was 1800 cals a day so not restrictive at all and I certainly never felt deprived

But the main motivation for trying IF is the health benefits as Alheimers, strokes and cancer run in my family. Therefore I hope that I will continue to fast once or twice a week even after I reach goal.
