The Nutritarian diet, created by Dr. Joel Fuhrman, emphasizes plant-based foods like leafy greens and non-starchy vegetables, making up 60% of your intake. This diet avoids processed foods, oils, dairy, refined grains, and deli meats, focusing on high-fiber, low-calorie foods like fruits, legumes, nuts, and seeds. Benefits include weight loss, feeling full longer, heart health improvements, and nutrient-dense food intake. However, it can be time-consuming due to meal prep, may require supplements for certain nutrients, restricts snacking, and might cause stomach discomfort for some. Consulting a doctor or dietitian before starting is recommended.
