Study: Plant-Forward Diet Helps Reduce Body Fat and Muscle Loss as We Age

A study published in the journal JAMA Network Open found that a plant-forward Mediterranean diet combined with increased physical activity can reduce body fat and prevent muscle loss in middle-aged and older adults. The study involved 1,521 participants aged 55 to 75 without a history of cardiovascular events who were either overweight or obese. The group following a lower-calorie Mediterranean diet with exercise experienced significant reductions in body fat mass and an increase in lean mass compared to those receiving general dietary advice.

The researchers emphasized the metabolic significance of reducing visceral fat and preserving muscle mass, as excess visceral fat and muscle loss are associated with an increased risk of various health issues. The Mediterranean diet focuses on plant-based foods, fruits, vegetables, whole grains, nuts, legumes, and healthy fats like olive oil while limiting processed foods and red meat. Additionally, consuming enough fruits and vegetables is important for gut health, as microorganisms from these foods play a role in shaping the human microbiome and promoting overall health.
