Уточню, по поводу соотношения белков и жиров , как написала выше - 80/20 или 70/30 - имеется в виду калорийное отношение, получаемое от жиров и белков - а если учесть что на 1 жира - 9 ккал , а на 1 г. белка - 4 ккал, то количество жира по весу уменьшается...

Lex, perhaps you can help me to understand fat to lean meat ratios in a low-carbohydrate diet. When people are asked how much they eat of fat relative to lean meat, they often answer somewhere around 80%. Does this mean that one would be eating 80% fat by weight or caloric content? This is something I've never understood.

We usually mean 80% of calories from fat. This equates to about 30% fat by weight. I personally stay in the region of 70% to 75% of calories from fat (about 20% to 25% of fat by weight)most of the time. When I get upwards of 80% of calories from fat or above, I find that a lot of the fat is not digested and it is eliminated as soft pasty stools that float. With too much fat in the diet, a bowel movement is akin to squeezing a tube of toothpaste. Since the fat is not digested, it is calories wasted so why eat it.
Remember that I'm eating ALL the fat in my meat because I eat it raw. Most people purchase ground beef with 30% fat (and therefore 80% of calories from fat) because it is the cheapest, but then they cook it until much of the fat is rendered out and they eat the cooked meat and throw the fat away. Meat cooked medium to well done can lose 75%-95% of its fat content. If you throw the fat away, the cooked meat might only contain between 15% to 35% of calories from fat.
