I've been trying to lose weight. What diets are effective?

The most popular and effective diet is the Mediterranean diet, which focuses on eating whole grains, fruits, vegetables, nuts, legumes, fish, olive oil, and moderate amounts of dairy products. It also encourages physical activity and limits red meat and processed foods. Other diets that may be beneficial include low-carbohydrate diets, intermittent fasting, and veganism.
