Study Finds Activity (not calorie intake) is Key in Weight Gain

Study Finds Activity Key in Weight Gain

PORTLAND, Ore. (April 17) - Staying active may be more of a factor in fending off weight gain for adults than cutting calories, according to a new study.

The study on monkeys at the Oregon National Primate Research Center found no strong relationship between the level of food intake and weight gain.

The most active monkeys gained less weight despite being fed the same high-fat diet, researchers said.

"Considering the fact that 60 percent of adult Americans are overweight or obese, this is a finding that affects a large percentage of the adult population in this country," said Judy Cameron, an Oregon Health & Science University neuroscientist who led the study.

Cameron and her colleagues studied 18 adult female monkeys during a nine-month period. About a year before the study, the ovaries were removed from the animals to simulate menopause in humans. In addition, all of the animals were placed on a high-fat diet, similar to the diet of a middle-aged woman.

Food intake, body weight and body fat were closely tracked. Researchers also tracked the activity levels of the individual monkeys using a small device called an accelerometer, which was worn on a collar.

The results suggest that, while increased food intake has the potential of increasing body weight, it does not appear to be the primary cause of weight gain during the adult years.

"This is especially important to middle-aged Americans who typically witness a jump in weight," Cameron said.

The study was released online this week before publication in the American Journal of Physiology: Regulatory, Integrative and Comparative Physiology.
 
You mean exercise helps your metabolism, and the added muscle mass helps keep weight gain down even on a high calorie diet? No way!!!!

Way!
 
People seem to need the obvious stated.

How many people try and lose weight by exercise?
How many people try and lose weight by dieting alone?

Tell me if this study is worthless.

Well, actually this isn't as "obvious" as you all seem to think it is.

In fact, the majority of people on this forum mistakenly believe weight loss is as simple as mere calorie restriction, i.e., "take in fewer calories than you burn."
 
I've always said it isn't about restricting calories but changing what you eat. That still cannot be ignored. Exercising is good, but so is eating better. And you want to do both. Studies like this almost make it seem like eating healthier is a waste of time, which it clearly is not.

Here is what I don't understand:
"The most active monkeys gained less weight despite being fed the same high-fat diet, researchers said. "

Shouldn't the inactive monkeys been eating less?

That doesn't make it less obvious. I wouldn't exactly call ATOT the source of all knowledge or anything.

Basically, anyone who ever speaks to a doctor, physical therapist, physical trainer, exercise guru, health nut, etc. knows this.
 
Is this the same group of "scientists" that figured out having sex was more enjoyable than self service?

No, but AT has, on average, a higher intelligence than the general population. These are bright, educated kids and adults here (if not a little naive and immature). If they think weight loss is that simple, what does the general public think?

They think that diet pills sold on the game show network are the trick to weight loss. Think Requiem For a Dream.

Now there's a depressing movie.
 
Well, I've lost about 25 pounds since January, mostly through better eating. Initially my cardio had increased but that has tailed off in the past 2 months. I have been doing more weight training since the cardio tailed off, but I believe the caloric intake has been the biggest factor in my weight loss.

I've been saying for years that energy balance is NOT the correct balance to look at. It is not:

[*][calories in] - [calories out] = [mass change]

Instead, you need to look at mass balance:

[*][mass in] - [mass out] = [mass change]

And all I get is flames at my posts and anger from the public. They want to believe that energy change = mass change. They don't want to believe that mass change = mass change. This is obvious to any scientist, yet the general public thinks otherwise. So, Amused, you are correct any truth in weight loss is NOT obvious to the public.

This study is just one more reason that the first equation I wrote is wrong. Increasing calories in doesn't necessarilly mean increased mass. I like this quote from the abstract:
there was no difference in weight gain between the monkeys with the highest versus the lowest caloric intake, total metabolic rate, or basal metabolic rate.

Calories don't matter. Metabolism rate doesn't matter. Forget these silly, unfounded, and scientifically false notions. Stop taking weight loss advice from a heath nut, nutritionist, trainer, therapist, etc who has never studied mass change in their life.

..that's the truth that so many don't want to hear.

 
You need a negative net calorie intake over a given period to lose weight in that period.

It's not science, it's not voodoo. The media has been obsessed with "finding the cure to obesity". Well, here it is.

/thread
 
So they kept all the monkeys on the same diet, then said that the ones that exercise the most gained the least weight, therefore activity matters most and diet matters little? Someone doesn't understand the scientific method.
