A meat-based diet primarily consists of animal products, including red meat, poultry, and fish. This type of diet emphasizes protein intake and often includes fewer carbohydrates and plant-based foods. Proponents argue that it can lead to increased muscle mass and improved satiety. However, critics of meat-based diets raise concerns about potential health risks, such as heart disease and certain cancers. They also highlight environmental impacts, as livestock farming contributes to greenhouse gas emissions. Balancing meat consumption with fruits, vegetables, and whole grains is often recommended for overall health and sustainability.
