I'll give it a look
Yes, indeed. Grains for instance - which receive so much of a bad wrap these days - are meant to be eaten by farms that worked the fields all day. Not by sedentary couch potatoes.
Full carnivore dies are unnecessary at best; and potentially harmful at worse. Yeah, the Inuit and some Siberian tribes traditionally eat fully carnivore, often raw meats at that; but their foods are of much higher quality than what the standard westerner can buy at a market, and they eat all the organs as well. And even then, those peoples are particularly adapted to the fully carnivorous diet and metabolize excess animal fats and proteins more efficiently than other groups of people.
Honestly, just exercise/live and active life and get decent sleep for starters. And eat real food without additives. Real meats, with occasional organs; real whole grains like rice and beans; oils like olive oil (but avoid most seed oils); eggs (preferably from a good source like a local farm if possible, but you can't be too picky in the modern western world); and some fruits and vegetables from time to time. Nuts to snack on. It doesn't have to be over complicated; just like an active life, get some good sleep and eat a bunch of whole foods.
The biggest "x factor" that none of us can really control at the moment, is environmental pollutants like pesticides, micro plastics, genetically modified foods, and other industrial pollutants in the environment and thus, the food supply. All of this stuff is in the foods we eat; very few people are lucky enough to avoid this i.e. they live around a bunch of local farms in rural areas, and even then they can't completely avoid environmental pollutants. It's just a fact of the modern world, and it is taking a heavy toll on humanity, particularly the testosterone levels of men.
And one more thing: bread is not an evil word. It's just that most people do not eat actual, real bread. Same thing with dairy; not an evil word. But comparing store bought cows milk to actual fresh farm milk from grass fed cattle, is like comparing drinking chalk to drinking the richest milk shake you can imagine. Doesn't even compare.
For example, this:
and this:
Do not combine to make, or in any way compare, to real food like
this:
Not being a food snob. But that's just facks.
Real bread and
real cheese is some of the most nourishing foods a person can eat and entire nations still live on food like this.
Also, the crock pot is your friend. Every Sunday I'll make a Sunday roast. Beef or pork roast with potatoes, carrots, maybe a leek if I have one, and olive oil. Simple meal can last for days if it is a big enough roast. Can slow cook chicken breast in the crock pot at well, comes out great.
