Also looking for an answer to this question! I’ve been trying 16:8 for a week or 2 and it’s just not matching up with my schedule at all with uni/work/hobbies/my partner’s schedule.
I’m wondering if a 15:9 fast would still have benefits!
Anything can work depending on your calorie input, but at a certain point you’re not really doing IF. But if it works for you that’s what’s really important. There’s some debate, but a lot of people consider IF to be a minimum of 16/8. For the poster that asked about 15/9, sure and it’s just going to come down to eating behavior/calories in that 9.
