Dieters typically eat further protein to stave off hunger and forestall loss of muscle tissue that always comes with weight reduction.
However in a study of 34 postmenopausal ladies with weight problems, researchers at Washington University Faculty of Drugs in St. Louis discovered that consuming an excessive amount of protein eliminates an important well being benefit of weight loss : enchancment in insulin sensitivity, which is critical to reducing diabetes danger.
The findings can be found Oct. 11 in the journal Cell Stories.
"We discovered that ladies who misplaced weight eating a excessive-protein food regimen did not expertise any improvements in insulin sensitivity," mentioned principal investigator Bettina Mittendorfer, PhD, a professor of medication. "Nonetheless, women who lost weight whereas consuming less protein were significantly more sensitive to insulin on the conclusion of the research. That's important as a result of in lots of chubby and obese people, insulin doesn't effectively control blood-sugar levels, and ultimately the result is kind 2 diabetes."
Insulin sensitivity is a good marker of metabolic well being, one which usually improves with weight reduction. In actual fact, the ladies in the research who lost weight whereas consuming much less protein experienced a 25 to 30 p.c improvement of their sensitivity to insulin.

Mittendorfer and her colleagues studied 34 women with weight problems who had been 50 to sixty five years of age. Although the entire girls had physique mass indices (BMI) of at the very least 30—a BMI of 30 or extra signifies vital weight problems—none had diabetes.

The contributors had been randomly placed into one in all three groups for the 28-week research. In the control group, girls were asked to take care of their weight. In one other group, the ladies ate a weight-loss food regimen that included the advisable each day allowance (RDA) of protein: 0.8 grams per kilogram of body weight. For a 55-yr-outdated lady who weighs 180 kilos, that will come to about sixty five grams of protein per day.
In the third group, the women ate a weight-reduction plan designed to assist drop a few pounds, however they consumed more protein, taking in 1.2 grams per kilogram of physique weight, or nearly a hundred grams for that very same one hundred eighty-pound woman.
"We offered all the meals, and all the women ate the same base food plan," Mittendorfer defined. "The only factor we modified was protein content material, with very minimal adjustments in the amount of fat or carbohydrates. We needed to hone in on the effects of protein in weight loss."

The researchers targeted on protein as a result of in postmenopausal ladies , there is a widespread belief that consuming extra protein might help protect lean tissue, protecting them from losing an excessive amount of muscle whereas they lose fat.
"If you drop some pounds, about two-thirds of it tends to be fat tissue, and the other third is lean tissue," Mittendorfer mentioned. "The ladies who ate more protein did are inclined to lose a bit of bit much less lean tissue, however the whole distinction was solely a few pound. We question whether or not there's a significant medical benefit to such a small distinction."
The ladies who ate the recommended amount of protein noticed huge benefits in metabolism, led by a 25 to 30 % enchancment of their insulin sensitivity. Such improvements lower the risk for diabetes and cardiovascular disease. The women on the high-protein food regimen, in the meantime, didn't experience those improvements.
"Changing the protein content material has very large results," Mittendorfer stated. "It's not that the metabolic advantages of weight reduction have been diminished—they had been fully abolished in ladies who consumed high-protein diets, though they misplaced the same, substantial amounts of weight as girls who ate the weight-reduction plan that was decrease in protein."
It is nonetheless not clear why insulin sensitivity didn't enhance within the high-protein group, and Mittendorfer stated it's not known whether the identical results would happen in males or in ladies already recognized with kind 2 diabetes. She plans to continue researching the subject.
