My basic plan has been to eat 2 meals a day, no mammals, very little bird, little seafood, as much egg, grain, fruits and veggies as necessary. I have done this for 20 years. For seven years before that I was not eating birds (I never gave up seafood). Before that I was a 3-meal-a-day, meat-eating lad. In the 70s autopsies indicated that the mammal-heavy (red meat) diet was clogging arteries in the cadavers of 19-year-olds coming back in bags from Vietnam.
In the past 20 years I have been eating two meals a day with a lighter lunch than dinner. At dinner time (preparing for the fast) I satisfy my hunger. While I am sleeping at night I am digesting (most mammals sleep post eating). So 0.25-0.30 of the day I am metabolizing. The rest of the day I am burning what I eat.
Metabolism rate is the rate of the cellular clock. The faster this clock runs the shorter time the clock can run, similar to the hour glass or the egg timer.

I am not religious, totally guided by hard and fast rules, once in a while I eat 3x a day and snack. When I do, I find that I enjoy each meal less. Passing the day and actually getting hungry until I feel like going out and killing prepares me to really enjoy eating. I think this is likely healthier; eat it and burn it is my philosophy.
Strangely enough glycosylation of proteins (chemistry of protein and sugar, Maillard reaction) is a process that runs out of control in diabetics. Proteins are the gene product; proteins are us. The same process happens at a much slower rate during normal senescence. Diabetes basically is galloping aging on the biochemical level.
Chemistry between proteins and carbohydrates abounds in the cooking process, but these are not our proteins. They are the protein of the stuff we eat. Humans have been cooking food for all our historical time and throughout much of our prehistory--likely before we were human. We certainly can break down these cooking derived glycoproteins (there are many naturally produced glycoproteins) to simple sugars and amino acids. Cooked food is likely not more toxic than raw food.

We know however that a diet overly rich in mammal fat will not contribute to overall health. If you eat and burn a meat heavy diet, I think it still can be very healthy.
I feel like I am pontificating. Health, diet and longevity is a cross section of biochemistry that had my attention off and on for quite a while since my undergrad days. I have modified my diet relative to what I know and relative to my aging/ slowing metabolism as I move toward my 50's.
Watch me not last the week.
