PYY (hormone) Triggers Weight Loss
September 19, 2006
According to the British researchers -Eating protein rich diet triggers a natural weight-loss hormone. Recent studies suggest the hormone known as PYY (peptide YY 3-36) dramatically reduced appetite in both obese and normal weight individuals. When released in the gut, PYY reduces hunger.
Current studies suggest PYY is ingredient of the solution to obesity. Contrast with a normal-weight person, for example, an overweight person has to eat twice as many calories to trigger PYY.
"We've now found that increasing the protein content
of the diet augments the body's own PYY, helping to
reduce hunger and aid weight
loss," Batterham says, in a news release.
If this sounds like the Atkins
Diet, Batterham and colleagues say it's not. They
note that many people on the Atkins Diet eat a lot of
saturated fat as well as a lot of protein.
Research conducted study whether PYY really the key
to obesity.
They trialed the test on nine obese men and 10 normal-weight
men, team first looked at what kind of food best satisfies
hunger. They provided the meals - a high-protein meal,
a high-fat meal, and a high-carbohydrate meal - had
the same number of calories.
When team asked all the men said "the high-protein
meal best satisfied their hunger. Interestingly, the
normal-weight men found the high-fat meal more satisfying
than the high-carb meal, while the obese men did not".
Dimensions showed the high-protein meal triggered the
most PYY in all of the men. In the normal-weight men
- but not the obese men - the high-fat meal triggered
more PYY than the high-carb meal.
After observation nine obese men and 10 normal-weight
men Batterham's team genetically engineered a mouse
strain that did not have the PYY gene. These mice ate
massive amounts of food, and swiftly became obese.
Usually, obese mice fed a high-protein diet will eat less and lose weight. But a high-protein diet didn't help the PYY-defective mice lose weight - unless they also got PYY treatments.
