Re: question for CR support group about cr effects

[Guest guest]

Heed Francesca's advice for moderation. The fact that you lost 1

pound per day while you were sick means that your organism needs at

least that much reserve for when you get sick next time. The

consequences of being sick when your body does not have enough

reserves for healing itself may be harmful or fatal. Clinging to

life by a thread through minimal optimal nutrition may lengthen life

for mice in sterile cages, but it seems to me that for humans we are

still far from knowing with certainty what is optimum nutrition for

each individual taking into consideration age, sex, exercise,

allergies, genetic factors, etc. ... and we don't live in sterile

cages.

From the information in the files about probability of

diseases vs. BMI, I don't see an advantage for having a BMI less than

21.

Subject: question for CR support group about " cr effects "

Hi All,

I'm relatively new to the list and had a couple questions I was

hoping you guys could help me out with. First, a little background: A

few months ago I lost about 8 pounds in 8 days do to being

hospitalized for a while. I was not on CR then, and still haven't

started it yet. (at least not to any significant degree) I'm 24

and

(on the suggestion of some) am planning on waiting till I'm 25 to

make sure that my brain if fully developed before I start

significantly restricting calories.

In this study, those with BMIs between 18.5 and 21.9 seemed to be at

the lowest risk...

" Impact of Overweight on the Risk of Developing Common Chronic

Diseases During a 10-Year Period

Background: Overweight adults are at an increased risk of developing

numerous chronic diseases.

Methods: Ten-year follow-up (1986-1996) of middle-aged women in the

Nurses' Health Study and men in the Health Professionals Follow-up

Study to assess the health risks associated with overweight.

Results The risk of developing diabetes, gallstones, hypertension,

heart disease, and stroke increased with severity of overweight among

both women and men. Compared with their same-sex peers with a body

mass index (BMI) (calculated as weight in kilograms divided by the

square of height in meters) between 18.5 and 24.9, those with BMI of

35.0 or more were approximately 20 times more likely to develop

diabetes (relative risk [RR], 17.0; 95% confidence interval [CI],

14.2-20.5 for women; RR, 23.4; 95% CI, 19.4-33.2 for men). Women who

were overweight but not obese (ie, BMI between 25.0 and 29.9) were

also significantly more likely than their leaner peers to develop

gallstones (RR, 1.9), hypertension (RR, 1.7), high cholesterol level

(RR, 1.1), and heart disease (RR, 1.4). The results were similar in

men.

Conclusions: During 10 years of follow-up, the incidence of diabetes,

gallstones, hypertension, heart disease, colon cancer, and stroke (men

only) increased with degree of overweight in both men and women.

Adults who were overweight but not obese (ie, 25.0BMI29.9) were at

significantly increased risk of developing numerous health conditions.

Moreover, the dose-response relationship between BMI and the risk of

developing chronic diseases was evident even among adults in the upper

half of the healthy weight range (ie, BMI of 22.0-24.9), suggesting

that adults should try to maintain a BMI between 18.5 and 21.9 to

minimize their risk of disease.
