John 'the Man said:The biggest bunch of crock being pushed with absolutely no evidence is that skinny is healthy.
Your idea of skinny seems to be someone in the advanced sector with anorexia, or a starving peasant
in a famine-stricken sub-Saharan country. Of course, these individuals aren't healthy! They're
malnourished. It's easier to be malnourished when one is thin than otherwise, simply because food
intake is lower. But skinny is healthy when one has a balanced diet emphasizing energy-dense foods.
Quoted message said:The ideal body weight is at the high end of your normal body weight and even slightly overweight is
good, too.
You're claiming that body mass index (BMI) over 25 ("slightly overweight"😉 is good. The evidence
doesn't support this claim. For males above a BMI of 24, mortality rises, according to the appended
Norwegian study. (There's another issue raised in this study that needs to be discussed, but I'll
save it for a subsequent post)"

BACKGROUND: The relation between body mass index (BMI) and mortality is not clear in the
literature. An inverse relation between height and mortality has been suggested. We explore
these relations in a very large cohort in Norway. METHODS: We studied two million men and women,
age 20-74 years, who were measured during 1963-2000. These persons were followed for an average
of 22.1 years. We used Cox proportional hazard models in the analyses. Also, the optimal BMI
(the BMI at the time of measurement that was subsequently related to the lowest mortality) was
estimated. RESULTS: Over the study period, 723,000 deaths were registered. The relative risk of
death by BMI showed a J- or U-shaped curve, with the lowest rates of death at BMI between 22.5
and 25.0. In men, the optimal BMI increased from 21.6 when measured at age 20-29 to 24.0 when
measured at age 70-74. In women, the optimal BMI was consistently higher, increasing from 22.2
to 25.7. Mortality decreased with increased height in men; in women, mortality decreased with
height only up to heights of about 160-164 cm and then increased among the tallest women.
CONCLUSIONS: The relation between BMI and mortality was J- or U-shaped, with the "optimal" BMI
men and in women up to a height of 165 cm.
