I write today's post, fully aware that yesterday I ate four gingerbread cookies, two spritz cookies, one
"Beurre and Sel Jammer" (Butter and Salt Jammer), one blueberry strudel cookie, part of a brownie, and part of a chocolate-covered Rice Krispy treat. In my defense, I had come from a Christmas party, but nevertheless, this post should probably be labeled Do-As-I-Say-Not-As-I-Do.
People magazine tweeted this morning that, for the first time,
thirteen-year-olds will appear on the show
The Biggest Loser. And why not? In the last thirty years, obesity and its attendant health ills have crept downward to become a problem of even the young. Nor are Americans the only people getting fatter.
The Biggest Loser and its local spin-offs are hit shows in twenty-five countries worldwide and counting. Obesity is a big deal and big business. But what could be causing the worldwide weight gain?
If you're Dr. Robert Lustig, you think you've found the smoking gun. In his new book entitled
Fat Chance (Penguin, coming December 27, 2012), he shares his alarming findings and provides plenty of evidence to back them up.

Lustig, a pediatric endocrinologist at
UCSF whose
"Sugar: The Bitter Truth" lecture video got lots of hits on
YouTube, has been watching the rise of obesity and its attendant ills in
his practice over the last umpteen years. While not every obese person
is unhealthy (and many people with acceptable BMIs still suffer from
metabolic syndrome), obesity frequently brings in train "the cluster of
chronic metabolic diseases...which includes...type 2 diabetes,
hypertension (high blood pressure), lipid (blood fat) disorders, and
cardiovascular disease," along with "co-morbidities associated with
obesity, such as orthopedic problems, sleep apnea, gallstones, and
depression." Lustig even mentioned the increase of dementia as tied to
this whole mess, as insulin resistance leads to dementia!
Consider some of his alarming statistics:
- 1/4 of U.S. children are now obese;
- Greater than 40% of death certificates now list diabetes as the cause of death, up from 13% 20 years ago;
-
The percentage of obese humans GLOBALLY has doubled in the last 28
years; there are now 30% more overnourished (obese) people than
undernourished, worldwide;
- Fructose (all the sugars you can think of, apart from the sugar in milk) is "inevitably metabolized to fat";
- Fructose consumption has doubled in the past 30 years and increased six-fold in the last century;
-
The majority of humans, regardless of weight, release double the
insulin today as we did 30 years ago for the same amount of glucose;
this hyperinsulinemia leads to insulin resistance, the body thinking
it's starving, and increased eating, especially for foods high in fat
and sugar because our dopamine receptors aren't getting cleared--a
vicious cycle;
- The processed food industry has turned to
increased sugars of all kinds to improve flavor and shelf life; we eat
lots of processed foods; therefore, 20-25% of all calories we consume on
average come from sugars; in adolescents this number can approach 40%
of daily calories.
Because I was blitzing through this, I didn't
absorb the science as well as I might have, but Lustig helped me
understand that how often, how much, and how unhealthily we eat can be a
function not of choice but of our biochemistry. The feedback systems
and processing systems which served humans so well for eons were not
built to handle as much food as we eat nowadays, particularly the
avalanche of empty sugar calories. Sweets and fats used to be hard for
us to come by--if we hit a surplus, of course our bodies stored it up
(as fat) for a rainy day! Unfortunately, there are no more rainy days,
so we keep storing and storing and overloading the system.
Lustig's
book is not about dieting or losing weight--in fact he says we have
natural weights we gravitate toward, and there isn't a heckuva lot we
can do about it, exercise or no exercise. But obesity is a new thing
that is environmentally-aided, and that can be fought against.
His
conclusion? You can probably guess. Lots of fruits and vegetables and
fiber. The fiber in fruits requires enough work to digest that it
effectively negates the fructose. Milk or water to drink (lactose is not
processed like fructose). Meats (not corn-fed) and dairy (ditto) are
fine, but don't skip the produce. Whole grains (all the brown in
them--exactly how my son doesn't like them), but even then there's no
need for tons of grain. And, if it has a nutrition label, it's a
processed food. Use sparingly.
The low-hanging fruit Lustig
tackles first is ridding your life of soda, smoothies, frappucinos, and
fruit juice. (8 ozs of orange juice has more sugar than 8 ozs of Coke.)
If you do alcohol, do just enough wine to get the
resveratrol benefits
and then lay off. (Another source of resveratrol? Peanuts!)
As Lustig points out, changing one's food
environment is all but impossible for the poor. After all, corn and soy
receive massive government subsidies, making the processed foods based
on them cheap, cheap, cheap. Even if you have access to fresh produce,
your money goes farther on the stuff in boxes, and food stamps cover
soda. One of the more disheartening bits of the book was when he talked
about meeting with Michelle Obama's personal chef Sam Kass, the point
person for the White House Obesity Task Force. Kass admitted everyone in
the White House (including the President) had read Lustig's NYTimes
article "Is
sugar toxic?" but they would do nothing to help. "Because they don't
want the fight, this Administration has enough enemies." Sigh. Not that
the Republicans mentioned fared any better. Basically, changing our food
landscape is up to us. For those of us with the dollars, vote with our
dollars! If we don't buy it, not all the food stamps in the world will
make it profitable.
As I mentioned at the beginning of this post, it's kind of a bummer to read this going into
Christmas-cookie season, but one of my New Year's Resolutions will be to
improve the food environment for my kids. I'm already talking up the benefits of fiber and fruits and vegetables, and the juice boxes are history. (How I wish I had a time
machine! I would never have introduced our biggest consumption area for
processed foods--breakfast cereal. I can only comfort myself that we
don't eat any off of his "Ten Worst Children's Breakfast Cereals" list! In the meantime, I've converted my youngest to occasional oatmeal and have started making bran muffins for my oldest. The middle child's cereal tooth can only be tempered with homemade waffles, full of colon-busting whole grains and flaxseed.)
I highly, highly recommend this book. Pre-order it for your family as a Christmas gift that will keep on giving!
