The Mediterranean diet is a popular choice among health experts for good reason. Rich in fruits, vegetables, and whole grains, it offers protection against various diseases. Recently, researchers from Spain and the U.S. found ways to enhance its benefits.
Their study focused on nearly 5,000 obese adults. Researchers discovered that combining the Mediterranean diet with regular exercise, a calorie deficit, and professional weight loss guidance significantly lowers the risk of developing type 2 diabetes—by nearly 31%.
Professor Miguel Martínez-González from the University of Navarra emphasized that these simple changes can make a big impact on public health. “A modest, sustained change in diet and lifestyle could prevent millions from facing this disease,” noted Professor Frank Hu, a nutrition expert involved in the study.
In their research, published in the Annals of Internal Medicine, participants with metabolic syndrome—conditions that increase the risk of diabetes—were divided into two groups. One group followed the Mediterranean diet while reducing calorie intake by about 600 calories daily and incorporating moderate exercise. They also received professional coaching. The other group simply followed the diet.
After six years, those who embraced the additional lifestyle changes showed a significant drop in weight and waist size, compared to the control group. The findings are particularly timely, as nearly 4.3 million people in the UK were living with diabetes in 2021/22, with another 850,000 unaware of their condition.
Type 2 diabetes occurs when insulin production is insufficient, causing high blood sugar levels. This can lead to serious complications, including heart disease and nerve damage. Symptoms often include excessive thirst, fatigue, and frequent urination, though many remain asymptomatic.
During the study, participants who followed the diet and lifestyle changes lost over 3.3 kg and trimmed their waist sizes by 3.6 cm, while the control group saw minimal changes. This stark contrast highlights the importance of a holistic approach—diet alone is not enough.
As we face a growing diabetes epidemic, integrating healthy eating with exercise and support is crucial. A well-rounded approach can not only improve quality of life but also prevent the onset of serious health issues.
