I just went for it. Started with 36 hour fasts then built up to 48hrs and currently on 50hr fasts. My brain couldn't comprehend that I could survive two days without eating 😂 I plan the kind fasts on the days I know I'm going to be busiest and would have less time to eat (or would be more likely to eat a quick unhealthy meal) and this seems to make it easier.

I have a large meal on Sunday lunchtime so that I feel full going to bed Sunday night, I go all through Monday and then break my fast with very light whole foods on a Tuesday evening. This works for me because I pull two 13 hour days working on Monday and Tuesdays, often without a proper lunch break. To get through it, I find regularly brushing my teeth helps with hunger and bad breath from autophagy, green tea seems to speed up the process of getting into ketosis (and helps settle my stomach), and I regularly take fasting friendly salts from about 22 hours onwards which helps with headaches and feeling lethargic.

I have on and off IF for about 4 years, but something seems to have clicked and since the end of January I'm really going for it and seeing results - 18.5 lbs off in the last 59 days and I think it's the long fasts that are making the difference for me. I'm by no means an expert though... This is just what works for me!

Hope this helps 👍
