Researchers from the University of Navarra in Spain studied nearly 5,000 people between the ages of 55 and 75.
All participants were overweight or had metabolic syndrome, but none had diabetes at the start of the study.
One group followed a standard Mediterranean diet. The other group also followed a Mediterranean diet, but with fewer calories, more physical activity, and support from healthcare professionals to help with weight loss.
The study was published in the journal Annals of Internal Medicine.

Growing problem
Type 2 diabetes is one of the world’s most widespread diseases. According to Science Daily, more than 530 million people worldwide are living with diabetes.
Researchers point out that sedentary lifestyles, unhealthy diets, and rising obesity rates are contributing to the increasing number of cases.
Temple University also highlights that many people struggle to access healthy food and opportunities for exercise in their daily lives.

Participants who combined the Mediterranean diet with exercise and reduced calorie intake had a 31 percent lower risk of developing type 2 diabetes.
The group also lost more weight and had smaller waist measurements than participants who only followed the traditional Mediterranean diet.
Researchers therefore conclude that moderate lifestyle changes can play an important role in preventing type 2 diabetes.
