Eggs are probably your cheapest food on a budget. You don't need coconut flour, you need meat, veggies and fat (spices that you like but salt and pepper go a long way).
In an ideal world we would all eat grass fed, free range, wild animals preferably killed and butchered with our own hands. We can't all do that so do what you can with what you have and enjoy not eating the poisons like whole grains, wheat, fructose etc.
And you will have to forget the CW notion that fat raises cholesterol out modern western diet is based on the work Ancel Keys and the government at the time- cherry picked data and poor analysis has lead to the dietary epidemic we see now.
Eating primal is not a diet, it is a way of life.
Don't forget to play!
