Losing weight can be as bad as being overweight.

by Tanya Zilberter, PhD

Concerns and uncertainty about weight loss advice and education.

Recent clinical studies have revealed that not only weight gain, but also
weight loss may increase risks for heart diseases. This finding has led to
concern and uncertainty about weight management advice and education.

The relationship between weight change and subsequent risk of a heart attack
was examined in 7100middle-aged British men.

+ Men who gained 4-10% body weight had the lowest rate of heart attack.
+ The men who lost weight had an increased risk of heart attack.
+ However, when other risk factors like hypertension, diabetes, serum total
cholesterol, blood pressure, social class, initial body mass index, lung
function, and smoking status, were excluded, these men had a similar level
of risk to the stable group (no weight changes).
+ The men who gained10% bodyweight had a significantly increased risk oaf
heart attack after the above adjustment.
+ The bad news is, however, that men who were initially overweight or obese
showed no benefit from weight loss.

But haven't we been taught that:

Obesity is one of the cardiac risk factors along with elevated blood
pressure and bad blood cholesterol numbers?

Everybody knows this, right? But how about the following:
"Mexican Americans, a population with a high incidence of obesity, have the
same mortality rate as non-Hispanic white Americans, suggesting that obesity
does not increase death rate. In the United States, the percentage of the
population that is overweight has increased sharply since the 1970s, but the
mortality rate has actually decreased. The increase in body weight has had
little effect on mortality."

What's the matter?! Maybe obesity is not the reason for heart disease but
one of the consequences that cause both overweight AND heart disease?

"Obesity is a relatively weak risk factor for coronary heart disease but it
is closely associated with almost all other coronary risk factors. Thus,
becoming obese on a Western high fat diet, with development of excess
central fat, promotes thermogenesis through a wide range of biochemical and
hormonal parameters. Weight loss in middle-aged populations does not
apparently lower coronary heart disease incidence, possibly because flack of
specificity in methods of weight reduction."


The similar conclusion has been made by the National Institute on Aging,
Bethesda, MD, after following up 621 men and 960 women since 1982-84, when
they were an average 77 years old.

* Weight loss or weight gain history during previous years mattered more
than body weight at any given age in late life.
* Women who displayed greater weight variability (especially the yo-yo type
of weight changes) had an increased risk of dying in later life
* Age-adjusted risks of death were highest in women who had a large ( 10%)
weight loss.

In the study by the School of Public Health, University of Minnesota,
Minneapolis, among 33834 women aged 55-69, higher body weight
Variability was associated with higher risk of developing chronic diseases
(myocardial infarction, stroke, diabetes, bone fractures (especially hip
fractures).

Quite to the contrary, among 121,700 nurses participating in the Nurses'
Health Study program initiated in 1976 by Brigham & Women's
Hospital, Boston and followed up every 2 years, even moderate weight gain
after age 18 increases risk of diabetes, coronary heart disease,
certain types of cancer and total mortality. However, in this particular
study they did not seem to look at the weight variability and to
weight loss.

Looks like the best way to stay healthy is maintaining a stable weight no
matter how much you already weigh.

If you are already above your ideal weight, staying there is better than
both gaining even more swell as than losing pounds.

Exercise is always good for you, whether you lose weight or not.

So is healthy eating. Luckily, information about these two aspects of a
healthy life style is abundant and not controversial like that of
weight loss.

For instance:

A low calorie diet (800-1200 kcal/day) and bicycle ergometer training (15
min, 8 times a week) reduced body weight, cholesterol, and low-density
lipoprotein (bad cholesterol) levels, resting and working heart rate, and
blood pressure. Even better news is that it didn't matter how intensive the
exercise was, both 50% maximal and 30% maximal workouts worked just well
reducing those numbers. However, people working out harder were able to get
stronger and leaner than those working out less hard.

Oh well. I didn't want to live forever anyway. When I lose the weight and
keep it off, I'll at least look good in my casket. ;-) I think that
they're wrong about some of it too. I think that losing weight slow is the
way to go. If someone loses it fast is where the problems with the heart
may come into play, IMHO.

I don't know what these people were doing to lose the weight
but if they weren't exercising -- and weren't doing aerobic
exercise -- they did it wrong. The fact that the site didn't
include that issue in the report means that they either didn't
know what they were talking about, had an agenda, or made up the data.

By the way, the idea of not looking at smoking data when
looking at heart attack risk is NUTS.
