Eat a steak?
I don't want to confuse you, but here is what i currently do. I set a minimum protein and fat requirement for the day, make sure i hit that, and then whatever other calories i get, i get.
So something like
gets me to essentially 2600 calories. the rest is whatever i feel like eating more of to hit my goal of 3000 a day on this cut. One night recently, it was another 75g of carbs from some epic roast potatoes, where as last night i used the rest for extra beef with my tacos.
It doesn't have to be complicated, especially starting out. Switch up to something where you are getting good protein and fat and see how it goes for a couple weeks. Adjust from there.
