The KMUD thing was a body fat percentage of 30%, so potentially lower than people are picturing from a BMI. Context:
Andrew: Would you start with what you think the ideal body fat percentage should be?
Ray: I think it varies according to gender and age. For example, young women who are overweight have better outcome of breast cancer (a lower incidence of breast cancer) than those who are underweight.
Sarah: And what are you saying [as] young women?
Ray: In the 20's and 30's. And one of the greatest increases in cancer is occurring among women between the ages of 25 and the early 30's. It's tripled in the last 30 or 40 years in that age group. But because of that relationship it's better for a young woman to be on the plump side...
Andrew: With saturated fats...
Ray: Yeah, if it's a good diet. And then in older people, being somewhat leaner for women is reducing the risk of breast cancer. But in old people in general mortality is lower with heavier body weight. They just have a greater resistance to stresses. So you have to look at the individual, and their age and gender. And overall mortality goes down in old people who are slightly on the heavy side.
Andrew: So it's very much relative to age then. Age and gender then, because obviously that percentage will change.
Sarah: I thought you said that older people who are slightly more plump have...
Andrew: Yeah, he did...
Sarah: Have a more decreased mortality.
Ray: Yeah, same with increased cholesterol. And a slight increase in blood pressure in old age is good. Same thing with...
Andrew: What do you think that body fat percentage would be then? 20%? 24%?
Ray: I think a little higher.
Sarah: That's pretty low.
Andrew: That's too low, huh?
Sarah: I remember when I was 19 I had it measured at 19%
Andrew: Ah, ok.
Sarah: The person said, "I don't think you'd ever be able to get pregnant at 19%."
Andrew: So how about 30%?
Ray: Yeah, I think 30%.
