Diet programs are structured plans designed to help individuals manage their weight and improve their overall health. These programs often include guidelines on what to eat, portion sizes, and meal timing. They may focus on specific dietary approaches, such as low-carb, Mediterranean, or plant-based diets, to cater to different preferences and health goals. Many diet programs also incorporate physical activity recommendations and behavioral strategies to support long-term success. Some popular diet programs include Weight Watchers, Keto, and Paleo. Participants may choose a program based on their lifestyle, dietary restrictions, and personal objectives for weight loss or health improvement.
