I must admit, I’ve been conflicted about obesity. “Why conflicted”,
you may ask? “What’s to debate? If you’re fat or overweight you should get down
to the normal BMI”, right? Not so fast.
The two sides I struggle with
Diabetes and heart disease conferences bombard me with slides linking
obesity with an increased risk of Type 2 diabetes. And I’m warned that obesity
is the underlying problem responsible for our ills, including hypertension and
even some cancers. For the record, I have had high blood pressure since my 20s
as did my father—and no amount of weight loss with our in range BMIs
would have been appropriate to lower our risk. So I have my biases when it
comes to making assumptions about disease and body weight.
The focus on weight loss is unrelenting. Doctors, for instance, will
often refer their diabetic patients to me, pounding them with the message that
it’s all about their weight. Sure, weight loss may improve their levels. But simply
modifying aspects of their intake, and their activity, regardless of weight
change, can yield great improvements in blood sugar. Yes, regardless of whether
they have had much shift on the scale. And we’ve become so focused on those
darn BMI charts, using norms for the population as our targets, that we’ve
failed to consider what normal truly is for the individual.
Good outcomes with minimal weight change
A recent diabetes webinar referenced a few large, well done studies
about obesity, weight loss and development of type 2 diabetes. On average, a
weight loss of only 7% was enough to reduce the risk of developing Type 2 diabetes by 50-68 %, in these 3 studies (one referenced above)!
That’s right. If you are a 200 lb individual (regardless of your BMI), a 14
pound weight reduction can dramatically lower your chances of getting diabetes.
A 5-6 % to 10% loss in body weight in obese individuals significantly
decreased BP in those with hypertension. That said, an even greater improvement
was seen in those who also followed a diet high in fruits, vegetables, and low
fat dairy products—consistent with the DASH diet for lowering blood pressure.
They’d still be considered obese, mind you. But that amount of weight
loss may be just fine!
Why pushing for weight loss may be a bad idea
Recently, I attended a 2 hour presentation at the Renfrew (Eating
Disorder) Center by a Dr. Lowe, from Drexel University, a researcher who
studies weight suppression. Weight suppression
(WS) is the difference between your highest, non-pregnant, non-ill BMI and
your current BMI. It was truly fascinating and in some ways depressing, what
his and other studies show.
|
Priceless. |
The degree of WS predicted many undesirable effects. CBT, the
treatment strategy that engages your thoughts and feelings to change your
actions, was less effective in those with greater WS. In addition, the impact
of staying at a lower BMI (lower than your historically normal BMI) doubled the
rate of binge eating (although this was not seen in some other studies). Higher
weight suppression predicted worsened symptoms, including depression and ED psychopathology
in anorexic patients, too. In ‘weight restored’ AN individuals who do not
resume menstruation, there was a correlation with higher WS; even though they were at healthy BMIs (based on population norms) at program discharge, their
normal-by-the-population-based-BMI-charts were not necessarily healthy and
normal for them!

Larger sized, and beautiful. Seemingly content, too. |
Residual symptoms in those we view as ‘weight recovered’ may be a red
flag indicating that weight may further need to increase. I know, I know, this
is not what you hoped hear.
Also of note, (and also depressing), is the data on
pre-eating-disorder weights, even in young kids (think elementary school and
up). Before their eating disorder, those who went on to develop anorexia or
bulimia were at higher weights than their peers. Maybe healthy and appropriate
for them—just higher.
In other words, pushing your body to get to or to maintain a less than
ideal weight for you based on your history may add to your risk
of getting an eating disorder, will increase your odds of being unable to use
well-known strategies to change your thinking and actions, and is associated
with more subsequent weight regain.
The Fat Nutritionist also gives a great summary of why it’s a constant
battle to lose weight in her recent post Why Diets Don't Work.
If you struggle with bulimia, and have not had significant weight
suppression, your weight may possibly drop as behaviors improve.
Are you confused now? Do you question whether your actions can really
make a difference? Or frustrated that you are hopelessly unhealthy, given your
obesity?
So where am I at in this debate?

We come in all varieties--& we are not all at the 50% percentile for weight! |
I know all too well that modifying lifestyle factors can both improve
your health and support weight loss and well being, in those who are
overweight. I have witnessed significant weight loss—up to 150 lbs.—with a high
degree of weight suppression—that has been maintained over many years in my
patients. Perhaps the weight suppression data isn’t looking at weight loss via
mindfulness and healthy lifestyle changes, but rather just focuses on absolute
weight shift? That may be true for some studies.
But I have also seen some patients do all the right things while their
weight stayed steady. Which leads me to this: if you are doing your part—eating
mindfully and listening to your body, staying (or getting active), and you’re
not losing weight, then the answer is simple: you shouldn’t torture yourself.
You are doing what’s in your hands to do, to keep your risk low and to be fit
and healthy—in spite of the population-based links between weight and disease.
So don’t let these study summaries bring you down!
Being responsible for change. A case in point
A recent experience when I was traveling leads me
to clarify my position on weight change. I was eating dinner in a remote town
in Washington state, far from the foodie finds in the not so distant Seattle
and Vancouver cities. To set the scene, let me describe: the place was a dive,
to the point that my husband selected a deep fried entree figuring that that
was the greatest assurance that any contamination would be killed. There was a
salad bar—but it looked like week-old decay ready for the compost. If we
weren't so hungry, there's no way we would have stayed. But there was truly
nothing else around.
A family walked in. Dad, a very large mom, and a
very large school-aged girl, dressed in a snug-fitting cheerleading
uniform. And here's what I observed. The
girl wanted to order the steak tips and vegetables, but was urged to get the
cheeseburger and fries platter—it was cheaper. The dinner came with the salad
bar, so she chose from the limited options—a fruit salad and sad looking
iceberg, with creamy dressing. And she ordered a large soda—it just might’ve
been part of the package deal.
From my limited observation of her and her
family, (admittedly being in the booth behind them, I overheard much of their
conversation), they have frequent meals out, and rely on hunting season to put
food on the table seasonally. Food insecurity might play a role in their
decision to pack in the calories when the price is right at the diner. Her
parents’ role modeled consumption of large sodas and desserts in addition to
calorie rich entrees. And from what I heard, cooking wasn’t something that the
missus had any inclination to do. So eating in might have been no
healthier than a frozen pizza and a regular soda.

Some things just might need to change. |
It was quite enlightening, this uninhibited
overeating which was seemingly the norm for this family. Seeing this, I would
be foolish to believe that the young girl’s large size was solely due to
genetics, uninfluenced by her environment and limited alternatives.
Perhaps when she gets older she may decide to
shift her lifestyle—if she has the financial means to do so. But changing
behaviors and patterns is quite a process. In the meanwhile, she may suffer the
bullying of weight stigma and the weight yo-yoing consequences of fad diets.
Perhaps the impact of her weight will make team sports too challenging to
partake in—kids can be cruel. So in the end, her activity may decrease as she
continues on her path, living in her current environment.
She may embark on many attempts to lose weight
when she is a bit older, each attempt leaving her more despairing as the weight
regain exceeds weight loss, in spite of her good intentions to restrict her
intake and lose weight.
Or she may have success modifying her eating
behaviors and physical activity in a sustainable way. She might learn to cook
healthier balanced meals, and eat out less frequently. Perhaps she’ll learn to
trust that the food will still be there, that she can stop when she’s eaten
enough. Addressing eating behaviors—separating eating from distraction and
distinguishing physical need for fuel from all the other reasons we eat—may
result in significant weight change. I see this in my patients, and I’ve
written about a couple of them in past posts.
But don’t look at her at 25 or 30 years old with
scorn and disgust—she is not to blame for her situation and your sneers will do
nothing to better her situation.
And let me restate what I wrote in the Cupid post
about kids and BMI. If a child is high on the charts, but gaining each year
like any other healthy child, they may be just fine—if their behaviors are
appropriate. But if they are sedentary, or spending too many screen time hours,
or eating in front of the TV, or eating minimal amounts of fruits and
vegetables, and low fat dairy, for instance, then yes, I would address those
behaviors. And you know what? I’d suggest the very same thing if I saw an
average weight child, too.
Final words

Rethink being the 'skinny girl'. |
So think again about your idealized goal weight.
If you’re a normal weight by the standard BMI, but you deny your hunger and
restrain your eating, then weight gain may be the key to release the hold of
your disorder. And if you are overweight or obese and have been adhering to
healthy eating behaviors and physical activity, staying where you’re at—even
though you remain many pounds from your goal weight—may be just what you need.
And if you haven’t changed anything and maintain
unhealthy eating habits, some weight loss may result from more healthy
behaviors. Modest change may be enough to improve your health measures, even if
your weight remains in the obese range.
Pushing yourself by denying your body’s signals
and its history will only create harm. You will struggle with your thoughts and
your weight will likely climb as a rebound to over restriction.
There’s no simple answer. Significant weight loss
has its risks. And staying at a high weight without addressing lifestyle
factors also places you at risk. But focusing on healthy behaviors may be the
most reasonable solution.
