I tried IF for 3 months after hearing all the hype, and also recorded bodyfat and muscle mass figures from weekly scans. Consistent with your experience I lost weight but it was almost all lean mass -fat was reduced only slightly. I switched to a ketogenic diet after that and watched the fat melt away. IF clearly works for some people but it sure didn't for me.

> I switched to a ketogenic diet after that and watched the fat melt away. I can't IF with high carbs. It has to be keto for me. I wonder how many other people who can't make IF work have the same issue. I'd wager it's most of them.

  I was eating very low-carb when I ran into the aforementioned problem.

Can you say more about these weekly scans? Specifically, I am curious if they involve any x-rays.

  They are probably referring to DEXA scans: https://en.wikipedia.org/wiki/Dual-energy_X-ray_absorptiometry https://en.wikipedia.org/wiki/Dual-energy_X-ray_absorptiomet...

    Aren't those like 100 bucks a pop?

      There's a Dexa scan truck in my area that does them for $60, with discounts for multiple scans (e.g. quarterly). https://www.bodyspec.com/pricing https://www.bodyspec.com/pricing

Were you doing maintenance workouts at the same time? The human body, counterintuitively, consumes muscle mass first before fat when it is not in active use. Thus to maintain musculature you need to maintain not just protein but activity. A ketogenic diet, from the literature I have read, has no actual benefit in terms of body fat loss. This is due to the fact that the metabolic pathways shift, but towards dietary fats first and foremost. The pathways that eat muscle and then body fat continue to exist, meaning muscle tone is still at risk without a proper workout regime. However, I am glad to hear it worked for you! At the end of the day what matters is you reached your fitness goals and can maintain them in a healthy lifestyle.

the thing is that IF is a keto diet. The theory is that during IF period your body depletes all carbs stores and is forced into ketosis o produce energy.
