I love the carnivore diet when I'm eating at a maintenance or bulking level, but what about in a 800-900 calorie deficit?

I haven't found it sustainable after three months of cutting.

I already introduced 50-60g carbs pre-workout, but I've had to add another 50-60g carbs post-workout. After accounting for my protein goals, there aren't enough calories remaining for fat to fuel me.

Anyone else have experience with this?
