Obese people with diabetes are able to lose weight on high-protein diets and see improvement in both cardiovascular and renal health, without facing increased risks, according to new research reported by Medical Xpress.
The study, conducted by University of Adelaide PhD student Eva Pedersen, compared the effects of a high-protein and standard diet in a year-long study involving 45 obese people with Type 2 diabetes.
The results show that weight loss achieved by both diets resulted in a range of benefits for the participants.

"High-protein diets are commonly used in our community, but concerns have been raised about the potential harmful effects of these diets on diabetic people's renal function, which is often already compromised due to their condition," said Peter Clifton, affiliate professor at the University of Adelaide's School of Medicine and Eva Pedersen's supervisor.
Within the first six months of the study, both diets helped the participants to lose weight, with almost 9 percent of body weight lost by those on the high-protein diet and more than 6 percent by those on the standard diet.
"Far from seeing any problems caused by the high-protein diet, the participants' weight loss resulted in improvements to their renal health, as well as to their overall cardiovascular health and the control of their blood-sugar levels," said Clifton.
The results were published online in the journal Nutrition, Metabolism & Cardiovascular Diseases and in the American Journal of Clinical Nutrition.
