A new study found that combining a lower-calorie Mediterranean diet with exercise and nutritional support can prevent type 2 diabetes in overweight adults aged 55-75. The study, published in Annals of Internal Medicine, involved 6,874 participants who followed either a Mediterranean diet or received no dietary restrictions.
The participants who followed the Mediterranean diet reduced their daily calories by 600 calories, limit added sugar, refined breads and cereals, butter, cream, processed meats and sweetened drinks. They also engaged in moderate exercise daily, with at least six days of aerobic exercise per week, along with exercises to improve strength, flexibility, and balance.
The results showed that the intervention group had a 31% lower risk of developing type 2 diabetes compared to those who only followed the Mediterranean diet. This is attributed to improved diet quality, increased physical activity, and modest weight loss. The study also found significant reductions in body fat percentage and visceral adiposity (belly fat) among participants.
The key to the study’s success was the combination of multiple components: a healthy diet that emphasizes plant-based foods, healthy fats, and lean protein, along with regular exercise and professional support. This approach resulted in lasting lifestyle changes, with minimal recidivism over six years.
The Mediterranean diet, which is not a restrictive diet but rather an eating style, has been linked to various health benefits, including reduced risk of diabetes, high cholesterol, dementia, depression, breast cancer, stronger bones, and a healthier heart. The diet emphasizes simple cooking methods, social interactions during meals, and mindful movement.
