Why Do High-protein Diets Work?
May 9, 2003 Carnivores, rejoice! Red meat ability be key to your high-protein diet. That's the award from a new study, presented at an annual meeting of the American Affection Association.
"This is not the Atkins diet," says advance investigator Manny Noakes, PhD, a analysis dietitian with the Commonwealth Scientific Industrial Research Organization in Adelaide, Australia. "This is a high-protein diet, but it includes added fruits and vegetables than Atkins," she tells WebMD.
The Atkins diet, which has fatigued criticism from dietitians, is a high-protein diet but allows few carbohydrates (at atomic in the aboriginal few weeks). Later, dieters are accustomed to gradually add in bound amounts of fruits and vegetables. Atkins allows too abundant saturated fat and is too skimpy on fruits and vegetables, abounding dietitians say, but analysis has apparent that people on the Atkins diet do lose weight after advancement their cholesterol.
In their study, Noakes and colleagues set out to assay red meat's effects -- actual angular red meat, that is -- on accident factors for affection ache and diabetes, she explains. However, the after-effects angry up a surprising conclusion.
But aboriginal the data: 100 women were enrolled in the abstraction -- all overweight, with an boilerplate physique accumulation basis (BMI) of 33. For 12 weeks, bisected the women ate a high-protein diet of 34% protein, 46% carbohydrate, and 20% fat. The added half ate a high-carbohydrate diet that was 17% protein, 63% carbohydrate, and 20% fat. Each diet consisted of about 1,340 calories, and protein in both diets was from angular red meat.
Who Absent Added Weight?
After 12 weeks, both groups absent weight -- but some of the high-protein-diet women absent essentially added weight. Those women who had triglyceride levels higher than 133 mg/dL -- a fat in the claret -- at the study's alpha lost 25% added weight, letters Noakes. At the study's end, the high-meat eaters also had 22% lower levels of triglycerides, she says. Top triglyceride levels are often apparent in humans at accident for diabetes.
Other measures of bloom -- "good" HDL and "bad" LDL cholesterol, claret sugar, and abnegation insulin levels -- fell in both groups.
"You can lose weight in lots of altered ways," Noakes says. "But assertive humans ability do bigger on a assertive comestible arrangement with less carbohydrates, added protein. They will feel beneath hungry, be able to tolerate eating beneath for best periods of time. We acquisition that's about accurate of high-protein diets."
Whether or not you accept top triglyceride levels in your blood, this blazon of red meat, high-protein diet ability plan for you, she adds. "It's whether or not a accurate arrangement apparel you. A high-carbohydrate diet -- rice, pasta, fruit, vegetables -- hasn't consistently formed for people. There are lots of strategies to lose weight, and this is one of them."
