When i first started paleo i lost lotsa weight, when i started IF the next plateau shattered and i lost weight i thought was permanent.
At that point i decided to go for another goal and fasted 24 to 36 hours followed by a giant 5 to 6000 calorie high fat meal over the course of 2 hours and back to fasting. That combined with lots of movement and heavy lifting, body weight exercises, and a 5 to 8 hour hard hike/climb every week got me down to a ripped 160 lbs
I am certain however that the fasting and carb avoidance was 90% of the weight loss
Felt great but life gets in way and its not easy to maintain that lifestyle
Sounds about right by what I’ve read and experienced.
