A calorie is a calorie (absorbable calories, that is)
Yes, Nathan. Fiber is good. There should be no negative connotation implicit in fiber.
I like the calorie is a calorie idea–because it's true. The body maintains blood sugar within a range through transformation of excess into fat and through metabolism of fat to reconstitute blood sugar after anaerobic metabolism of blood sugar–gluconeogenesis–to restore a deficit. Sugar becomes fat. The energy from fat becomes the energy in sugar. (I realize I am oversimplifying–animal starch, glycogen, has a role, for example–but I think this describes the fundamentals of it.)
The rule of thumb for fat is to avoid fat-dense foods because ounce-for-ounce you get more calories from fat, but a calorie–*available* (absorbable) calorie, that is–is a calorie, regardless of its source.
Someone studied women in America and women in Africa. They thought they were going to find similar consumption but more expenditure of calories in Africa–but, no, they found and reported the converse, similar expenditure but more consumption in America.
