September 21 (UPI) – A small study has found that dieting by limiting protein intake may be as effective as restricting calories for people trying to combat obesity, diabetes and high blood pressure.

This means leaving the steak aside, passing the mashed potatoes.

The study By researchers in Brazil and Denmark, they compared the effects of protein and calorie-restricted diets in patients with metabolic syndrome, and it was published in the journal Nutrients.

They said their findings confirmed previous studies that included experiments on mice.

according to Mayo Clinic, up to one in three Americans has metabolic syndrome, which is defined as a group of conditions that occur together to increase the risk of heart disease, stroke and type 2 diabetes.

These conditions include high blood pressure, high blood sugar, increased body fat around the waist, and abnormal levels of cholesterol or triglycerides.

“The study showed that reducing protein intake to 0.8 grams per kilogram of body weight was sufficient to achieve approximately the same clinical outcomes as caloric restriction, but without the need to reduce caloric intake,” said Rafael Ferraz-Panitz, lead author of the study.

Dieting by restricting the amount of protein eaten may be a “more attractive and easy-to-follow nutritional strategy for people with metabolic syndrome,” Ferraz-Banitz, a postdoctoral researcher at Harvard Medical School’s Joslin Diabetes Center, said in a news release. .

The study was conducted by an interdisciplinary team of scientists, including those affiliated with the University of Copenhagen in Denmark, the University of São Paulo and the National Cancer Institute in Brazil.

It involved 21 volunteers with metabolic syndrome, who were analyzed for 27 days while the researchers monitored their diet. Throughout this period, they were transferred to the teaching hospital of the Ribeirão Preto School of Medicine in São Paulo, Hospital das Clinicas in Ribeirão Preto.

Each volunteer’s daily calorie intake was calculated as a function of basic metabolism, given resting energy expenditure, the statement said.

One group ate what the researchers called a Standard Western diet: 50% carbs, 20% protein, 30% fat, but with 25% fewer calories.

In the placebo group, protein intake was reduced to 10%, and calorie intake was adapted to each volunteer’s baseline energy expenditure.

After 27 days of monitoring, both groups achieved similar results in terms of lower blood sugar, weight loss, blood pressure control, and lower triglyceride and cholesterol levels, the researchers said.

Both regimens improved insulin sensitivity after treatment. Body fat decreased, as were waist and hip circumferences, but no loss of muscle mass, Maria Cristina Vos de Freitas, study co-author and professor at the Brazilian College of Medicine, said in the statement.

Scientists noted that it is known that lower body fat is associated with lower blood sugar and higher levels of normal lipids and blood pressure.

Despite the promising results of their research, they noted that the participants’ meals were customized. They focused on a specific category of patients with metabolic syndrome: obesity, diabetes, high blood pressure and abnormal cholesterol levels.

But the researchers said it’s tempting to extrapolate the results, noting that research has shown that plant-based diets benefit people with metabolic syndrome and that the excessive protein intake common in the standard Western diet could be a problem.
