Dietary carbohydrate is not necessary for strength training/muscle building, although it is obviously beneficial for some, and I don’t doubt that it’s essential if you’re very serious about body building. But as a type 2 I personally recommend lifting in ketosis and seeing how you get on.
No snacks. Just steak & eggs after training. And good luck with everything. Please keep the thread updated, as this is an area I’m currently into. Still a weakling, but getting stronger and more defined on a carnivore diet with around 10g carbs per day, all from dairy and incidentals.
