hey all! so I was wondering when I will know when my body is ready to fast? My husband and I have been on keto for 37 days now and neither of us is ever ok with fasting for long periods of time. he is still hungry a lot of the time and I wake up hungry. I have tried the BPT because I hate coffee and I just cant get past the taste of it. just tastes like drinking liquid fat…which duh…lol. I seem to do a lot of IF on weekends because I’m so busy doing everything that I had no time for during the week. Also the last week I am struggling with getting enough fat in versus carbs and protein. I’m still under or within all my macros but my fat is the lowest of the three. any advice would be great. thanks and keep it going all my keto friends!
How do i know when my body is ready?

I think it really just comes down to it happening spontaneously, right @mikki? 
There may be confounders where the body is fat-adapted and in terms of pure available energy ready to fast, but hunger is based on many hormonal signals as well as behaviors, so you might still feel hungry.
It might also be that the body is healing from past calorie-restriction or other metabolic damage and is demanding nutrients to repair the damage.
That being said, if someone is like me and wants to force the issue before natural satiety kicks in, I would go with the largest eating window that fits your schedule and stay with it - typically the most logical large window is 12 hours and exercise your fasting muscles while gradually reducing that window to something like 16:8 or 20:4 and then do a 24 hour fast.
While you’re practicing whatever fasting interval is working for you at the time, you’ll be learning new strategies for coping with fasting in a world where we’re bombarded with food and social situations where we’re expected to eat.
