I'm truly baffled by this entire thread.
How do you normally eat when you're at home?
How do you know you're insulin resistant?
How is eating a baked potato going to make you fat exactly?
You have to have your protein shake with almond milk? Seriously?
Fat gain or loss is a matter of calories. If you're doing "intense cardio" and watching your portion size this seems like a lot of histrionics for what is going to last only three more weeks.
