The phrase "low-carbohydrate diet" is a no-no in some circles, because it implies that a diet is high in fat. Often, the euphemism "high-protein diet" is used to avoid the mental image of a stick of butter wrapped in bacon. It's purely a semantic game, because there is no such thing as a diet in which the majority of calories come from protein. The ability of the human body to metabolize protein ends at about 1/3 of calories (1, 2), and the long-term optimum may be lower still. Low-carbohydrate diets (yes, the ones that are highly effective for weight loss and general health) are high-fat diets.
Healthy cultures around the world tend to consume roughly 10 to 20% of calories from protein:
Masai - 19%
Kitava - 10%
Inuit - 20%, according to Stefansson
Kuna - 12%
Sweden - 12%
United States - 15%
Human milk - 6%
The balance comes from fat and carbohydrate. Ask a traditional Inuit. If there's no fat on your meat, you may as well starve. Literally. "Rabbit starvation" was a term coined by American explorers who quickly realized that living on lean game is somewhere between unhealthy and fatal.
I learned about sugar VS corn syrup firsthand at team BBQ's; The times we drank Jarritos rather than Coke or Pepsi, I could not eat as much food.
Very true.. i find if I don't want to eat too much in the morning, I will have a small glass of milk/chocolate milk, about 15 mins before thinking about what to have for breakfast, turns out after that, I really don't want too much.
