A recent survey found that nearly half of U.S. adults plan to start a new diet in 2025, with the most common diets being low-calorie and low-carbohydrate options. However, plant-based diets have been shown to be effective for weight loss without restricting or counting calories, and also reduce the risk of obesity-related diseases.
Engaging in 30 minutes of aerobic exercise per week modestly reduces body weight, waist circumference, and body fat measures. Aerobic training exceeding 150 minutes per week may be needed for clinically important reductions.
