So, high insulin levels and fat will pack fatcells. That means that if
you eat carbs and fat, than your body is more likely to put on fat

In which case my suggestion of eating carbs-protein or protein and fat
makes sense. Is that correct?

Partially correct. The plans from Suzanne Sommers do this. A
meal either has carby foods or fatty foods but not both.

For the same total calories, a low-carb/medium-protein/high-fat plan
triggers less muscle loss than a high-carb/medium-protein/low-fat
plan. So if your only goal is to preserve lean staying low carb most
of the time works better.

But so long as you have sufficient protein intake the difference is
small. And it appears you do have sufficient protein intake.
