Whey protein and weight loss

[Guest guest]

All protein may not be created equal when it comes to weight loss.

Whey, or milk, protein may offer people who want to slim down a slight edge

over soy, a new study shows.

Researchers at the U.S. Department of Agriculture's Human Nutrition Research

Center randomly assigned 90 overweight and obese middle-aged adults to one

of three groups. The first group was asked to add protein drinks made with

whey to their normal diets, the second group drank protein drinks made with

soy protein, and the third group drank carbohydrate drinks.

Study participants weren't told which group they had been assigned to. All

the drinks, which were drunk twice daily, at breakfast and dinner, had the

same number of calories: 200. They also all had had 52 grams per packet, for

a daily total of 104 grams of added protein or carbs.

Researchers tracked participants' physical activity levels, weights, waist

sizes, lean and fat body mass, and blood levels of hormones related to

hunger and metabolism.

They also had people keep records of the other foods they were eating. The

researchers made sure participants were drinking the shakes during random

urine tests for levels of a chemical tracer they had added to the powders.

Seventy-three people completed the study, which is published in the Journal

of Nutrition.

*Whey Protein vs. Soy Protein*

When the study started, there were no significant differences between

groups, researchers report.

Men weighed an average of 218 pounds, while women weighed an average of

about 190 pounds.

Throughout the study, all the groups ate roughly the same number of average

daily calories, about 2,200.

After six months, people drinking the carbohydrate shakes had gained a

little bit of weight, about 2 pounds, which appeared to be mainly added fat,

compared to where they started.

People drinking the soy shakes had stayed about the same weight as where

they started.

But people drinking the whey protein had lost a little bit of weight and

body fat, about 2 pounds. Additionally, while the other groups saw little

change in the size of their waists, the whey protein group lost about an

inch around the middle.

The study was partially funded by the dairy industry.

*How Whey Protein May Affect Weight*

Researchers say a couple of things may help to explain the weight and fat

loss seen with whey protein.

People in the whey protein group had significantly lower blood levels of the

hormone ghrelin than people eating the soy protein or carbohydrate.

" It's a hormone that helps regulate food intake, " says J. Baer, PhD,

research physiologist at the USDA's agriculture research service in

Beltsville, Md. " So the higher concentration, the more hungry somebody

feels. The lower concentration, the fuller somebody feels. "

And though researchers really can't explain why this happened or what it

means, they found that people drinking the whey protein had cut back on

their carbohydrate intake by the end of the study, even though they weren't

eating fewer total calories and didn't know what kind of supplement they

were getting.

Though people drinking soy protein saw little change in their weight or body

composition during the study, they had higher levels of thyroid hormones

compared to those drinking whey. Thyroid hormones control metabolism and

higher levels may indicate a metabolic boost, though more research is needed

to fully explain what that may mean for weight loss.

For people who are hoping to replicate the results at home, researchers

advise picking a whey product that is also low in calories and fat.

" A lot of the whey products on the market also have a lot of calories in

them, " Baer says, " Consumers just need to read those labels. "

2 pounds in 6 months? I can say this hardly has any statistic significance. Also

if there were 3 groups the wey protein group only had 30 patients.

" 1 inch around the middle " is this of any significance as well? Considering it

was over 6 months...

" The study was partially funded by the dairy industry "

I wonder how much over production of milk USA has, and the advantage of the

department of agriculture to find new ways of selling milk products.

I believe it is significant - remember they were not trying to lose weight

and exercise was not part of the equation. PLUS one inch on the waistline,

where the indication is poor health as it " grows " . It certainly needs to be

studied further...
