I eat quite a lot of red meat, ribeye when I can, ground beef. Also pork, some fish. I prefer beef with a bit of fat. I am convinced that dietary fat and cholesterol are not the problem as we have been told for decades. My blood work is excellent. In fact, my doctor is on board with what I am doing but she also doesn’t quite know what to make of it. I think she still has some cognitive dissonance with someone eating…

Ah well my concern with eating red meat is related to the cancer risk and the impact on climate change. Are you worried about these issues in relation to your diet?

The health "risks" of red meat have been really overblown, see this meta-review (there are also two others by the same others, looking at slightly different questions): https://www.gwern.net/docs/longevity/2019-zeraatkar.pdf

>Most people can't maintain a caloric deficit 1. Do you have an evidence or is this just an assumption based upon your perceived "feeling"? 2. Why?

1. People on western diets. This isn't some hidden mystery.. it's in plain view. Plenty of studies done, or just ask _any_ doctor that sees patients, or any of your friends/family who have tried diets. Or search pubmed for diet adherence. 2. Because their base metabolic rate reduces over time to match their new reduced caloric intake.

So no evidence, you just have an unsupported opinion. Cool.

How do you feel about the climate change impact due to red meat production? I can't really imagine any way to decrease that other than drastically decreasing red meat consumption.

> the only thing that dieticians are consistently against is sugar in large doses. Not all sugar is the same. In fruit is in fructose form and "fiber bound". Refined sugar is the devil, but so are most refined products. Fructose be absorbed by cells with little to non insulin. Also, in the company of fiber it gets absorbed slower into the blood (less sugar spike). Finally there's the fat-sugar issue: in the company o…

Fructose, in fact is the villain. Check out https://peterattiamd.com/rickjohnson/

This to me is like telling a cow it should not eat grass. lol

Can someone explain why ketosis is the secondary energy system in the body and not the primary?

It is the primary energy system. When a woman get pregnat, weeks before giving birth, she starts to produce ketones for the baby (it doesn't matter how many sugar the mum takes). And when the baby is born, meanwhile he drinks from mum milk he is in ketosis, because more than 50% of human milk is saturated fats. So yeah, we are in ketosis until we start to eat "food" high in carbs. The body can't burn fats if insuline…

I think you mean 50% of the calories in human milk comes from saturated fats, not that the milk itself is 50% (by mass?) saturated fats.

I honestly haven't looked into it. I have heard some people say the idea that it's vastly more polluting than farming (farming what exactly?) is not entirely accurate. So there is at least some amount of controversy.

I know that in my country (Belgium), cattle is often fed the excess and/or unused part of some local productions (beetroot, hay from the farm ...). So that actually sounds useful to prevent waste.
