Doesn't just have to be chicken & steak.
You've got eggs you could have for breakfast some decent protein, fats & minerals there. Very good for you and gives you excellent arse ammo if you need to drop the bomb on someone. Takes about 3 minutes to scramble them.
Turkey, Beef, Pork, Lamb are some other meats to work in.
Fish, Tuna, Salmon, Mackerel, Cod, Plaice, Haddock etc.
So much food & flavour I don't think I could make do with just supplements alone!
What is it you find difficult about eat solid food out of interest?
you're just going to be missing out on lots of other vitamins & minerals by sticking to mostly supplements. Yes there are multi vit tablets but these aren't really the same and as a result of your current diet I think you're compositioning at the end of it may be quite different?
You've got decent macro's etc and plenty of the food groups but I just think there are healthier options out there. As I'm not sure of the implications on your health of eating mostly supplements. As the deffinition is to 'supplement' (aid) an incomplete diet. not to replace meals. Don't mean to be condescending or patronising just trying to help
