Should be quite possible.
Seems incompatible with your prior post,
You’re so far distanced from fat it’s not even on the horizon.
If you adjust nutrition you are just perpetuating the issue by again adjusting the equation of training/nutrition to a self-harm balance. You’re just finding it at a point of less nutrients and less expenditure.
My guess is that if you want to get back to a state where you’re not medically required to reduce your activity you are going to have to gain weight. Some of that will be fat.
If you reduce calories in you’re looking down the barrel of further reductions to your activity down the line.
