(A great post from my buddy Dave Soucy of The Truth about Diets)
Did you catch the latest diet study news that came out a week or so ago?

The
National Institutes of Health funded a study called "Preventing
Overweight Using Novel Dietary Strategies" or POUNDS LOST. Very catchy.
Apparently science is better when attached to a cute acronym.
They
certainly needed something going for them, because the conclusions the
researchers drew from this study are so simplistic and asinine that I
really thought my head was going to explode when I read them.
But
I’ll get to that in a moment. First, here is the premise of the study.
Basically they took a group of 811 obese people, split them to four
subgroups, and assigned a different type of diet to each subgroup.
The target nutrient compositions of the four diets were:
- Low-fat, average protein: 20 percent fat, 15 percent protein, 65 percent carbohydrate
- Low-fat, high protein: 20 percent fat, 25 percent protein, 55 percent carbohydrate
- High-fat, average protein: 40 percent fat, 15 percent protein, 45 percent carbohydrate
- High-fat, high-protein: 40 percent fat, 25 percent protein, 35 percent carbohydrate
The first point I’d make here is that I don’t agree that 25% protein would qualify as "high protein".
The
second point I’d make is that, despite the catchy name of the study,
there is absolutely nothing "Novel" about these dietary strategies.
Macronutrient manipulation isn’t novel. Ornish, Atkins, South Beach,
etc. are all diets based on macronutrient manipulation. But, as long as
we have a catchy acronym, who cares, right?
Anyway,
the results of the study showed that, regardless of whichever "novel"
approach the participants followed, they all lost about the same amount
of weight after 6 months and 2 years.
At 6 months, the average weight loss was 13 lbs, and at 2 years it was only 9 lbs.
Based
on this, the researchers concluded that macronutrient manipulation
wasn’t important and that all you should worry about is focusing your
"weight loss approaches on reducing caloric intake rather than any
particular proportions of fat, protein or carbohydrate."
The abject stupidity of this boggles my mind. Where do I begin?
Well,
how about with the fact that they made no distinction on body
composition and only looked at weight loss. So, a subject could have
lost 15 lbs of muscle mass and gained 6 lbs of fat, but the study would
just look at that as a successful 9 lb weight loss.
Next,
if you take a group of 811 OBESE people and they only average a 9 lb
weight loss over the course of 2 YEARS regardless of which diet they
were on, you’re right, the diets pretty much worked the same. That is, THEY ALL SUCKED!
9 lbs in 2 years?? Are you kidding me? And, after month 6, they actually started gaining back the weight they lost.
Hellloooo.
If someone is on a diet for 24 months, and they gain weight from months
7 through 24, well, I don’t think your diet is really working so well,
do you?
Here’s the conclusion that my independent review of the study came to:
"Research
shows that simply counting calories and not learning how to eat right
sucks if you truly want to lose weight and get healthy." Dave Soucy, 3/09.
To
further that point, research shows that a loss of 10% of body weight
will help reduce risk factors for heart disease and other medical
conditions. In this study, only 15% of the participants achieved a 10%
weight loss!
Let me do the math for you. That means that out of 811 people, over the course of 2 years, 690 of them did NOT achieve the 10% loss needed to reduce those risk factors. Unbelievable.
Okay,
here are a couple of takeaways for you. One, the news media reports on
new diet studies just about every day, and just about every day the
news media gets the story wrong.
Don’t
just blindly take what some reporter (who most likely knows nothing
about fitness and weight loss) spits out as fact. You need to really
read through the details to get to the truth of the matter.
And
two, if you’re obese and want to lose a little bit of weight and start
gaining it back again in 6 months, just go ahead and cut some calories.
It doesn’t matter what you eat, just cut some cals.
But,
if you really want to lose fat, improve your health, look and feel
better, and not start regaining the weight in 6 months, then admit to
yourself that you need to learn to eat right, get the proper nutrients
on a daily basis, exercise and stay away from lame researchers from the
National Institutes of Health.
