i honestly don't know
@Magsx1.
that was what i was always told BUT since i started LCHF more than a year ago i do not think it is that simple.
my ketones are at 2-4 throughout the day, so I am metabolising a lot of fat rather than storing it.
putting aside weight loss for a moment, for a T2 like me, getting my blood sugars under control was the priority & LCHF did that. the weight came off as a consequence. when i started to obsess about weight loss again, i found it distracting.
Going on to these 24hr fasts has given me fantastic blood sugar control and by focusing on that aspect, i suddenly find myself a stone down.
Fasting isn't for everyone. But if you want to try, start with pushing your meals closer together (and leaving wide spaces where you don't eat including sleeping hours), keep yourself well hydrated by drinking lots of water & my one meal of the day has a good amount of fish/lamb/duck/eggs & butter/coconut/olive oil so i am well fed.
good luck.
