Clean dieting. Reached a decent shape and BF %. Struggling with the last pounds.

[Renholder]

If you don't feel like you can eat less food then I would up the cardio or up the intensity of the workouts.

I bet I could, but I also fear eating 'too little' already with 4 days of PSMF per week. Is that a real concern? Or might it be that I simply need to eat even less than I already do?

I considered cutting fat on my workout days. But in truth, I was considering perhaps just starting with a completely new regime.

keto always helps push me over the last little hump.

Any specific keto diet?

I used to follow something called Timed Carb by Ironaddict back in the day. Not sure if that one's still relevant.
