It depends on your personality but here are a few rules
Beef - it is best to get grass fed/finished organically grown
Fish - best to get wild
Chicken - Free range, run around the barnyard type of life. (personally we can't eat raw chicken)
Other meats basically as wild as possible.
You can eat grocery store meat but it tends to be very low grade with antibiotics etc in it.
Fat - don't be afraid of it. The more the merrier, unless you are very obese. Then you might want to experiment.
Let your taste buds be your guide in regards to what to eat.
Some people (us) went full blast 100% from day 1. Some do the half pregnant deal LOL. Whatever you like.
There will be a transition period of anywhere from a week to maybe months where the digestion will build up steam, where you may feel a bit less energized or have differing symptoms but once past that you will find you eat a less. We eat significantly less, don't feel stuffed, tired, or interested in a big meal. The cook's day gets longer. Sitting down for a meal is not necessary.
Gradually you will find your health improves. My teeth have stopped going rotten. Haven't seen a dentist or had a toothache since I started. My body is smoothed out without gaining any weight.
As far as protein and fat goes, eat what you like and let your taste buds and desire be your guide. We fond that since there is less taste there is less desire to eat too much. We just eat what is needed. Hard to explain, easy to do.
