Then you would know that metabolisms differ (apparently) and perhaps absorption differs from individual to individual. That may account for the differences

Unless someone has small bowel disease of some sort or is an alcoholic and is starving that way, absorption is almost 100% in everyone (unless you're swallowing whole kernels of corn or grains of cereal). The body is really REALLY good at absorption. If it weren't, a whole lot more of us would be dead. The two most basic facts of nutrition are 1. if it's available, it's always easier to take in energy than it is to burn it off through basal metabolism (the biggest single chunk of energy expenditure) and voluntary physical activity and 2. no society has ever had more nutritious, cheaper food in an environment that requires so little voluntary physical activity in the course of a day.

I don’t know, since of course I don’t have a PhD. Where did you get your PhD? When I was doing my course work we didn’t have enough classes for a minor in nutrition which disappointed me greatly.

The University of Chicago and, no, I never saw Obama in the flesh or Michelle, either.

I don’t really disagree with what you’re saying, however, there seems to be something else at work. Maybe my skinny husband really doesn’t eat anything (altho he sure appears to). I know what we were taught, I also know that it doesn’t always jibe with reality.

And, a lot of the things I used to tell people (because it’s what I was taught) REALLY don’t seem to fit as I”ve aged. I have not real answer for why, I just know what is. On the other hand, my neuro thought my 2 miles per day at a pace of 3 miles per hour was really good, so that made me feel better!
