Various types of diets can significantly impact health outcomes by influencing body weight, nutrient intake, and the risk of chronic diseases. Diets rich in fruits, vegetables, lean proteins, and whole grains promote better health and reduce the risk of conditions such as obesity, diabetes, and heart disease. Conversely, high-calorie, high-sugar, and low-nutrient diets may lead to adverse health effects, including increased weight gain and metabolic issues. Therefore, dietary choices are critical determinants of long-term health.
