The protein in my meals I alternate slightly on two day cycles , tend to be bacon rashers and amoked cheese and milk, for breakfast, salmon, for lunch, and sirloin steak, and milk for dinner
On the other day, I swap bacon rashers for a large bag of cashew nuts for breakfast,aberdeen angus mince with a spicy stir fry sauce for lunch, and salmon steaks for dinner.
I of course add in carbs, including ready made potato salad, whole meal bread, ,and also a large raw salad every day, with red peppers and tomatos,All that stuff I get ready made from the supermarket, and really I think anyone can fry a steak or put some fish in an oven,it isn't rocket science.
I only swap around the protein due to the difference as fish and red meat and nuts for instance is slightly different in what it gives you, while I would love to subsist on sirloin steak I wouldn't be getting the complete amount of proteins . I don't bother with chicken or eggs (I would love to add in eggs, but I might be slightlyintolerant to them) because I find it hard to digest in the large amounts needed quickly, fish and steak go down like butter though, so I don't need to bother with protein shakes. I do however take animal nitro and amino acid supplement,If you can get your protein only from whole foods, if you can afford to do it, it is preferable but not essential, you need to be able to eat and afford large amounts of good quality meat and fish to do this though.
Have to be training hard though I train twice a day , or you will get fat even if the food isn't junk food,
