A diet plan is a structured approach to eating that helps individuals achieve specific health goals, such as weight loss, muscle gain, or improved overall wellness. It typically includes guidelines on what foods to eat, portion sizes, and meal timing. A well-balanced diet plan often emphasizes a variety of food groups, including fruits, vegetables, whole grains, lean proteins, and healthy fats. Creating a diet plan can involve consulting with a nutritionist or using resources like dietary guidelines and food pyramids. Many people also track their food intake using apps or journals to stay accountable. Following a diet plan can lead to better health outcomes and improved energy levels.
