The healthiest diet backed by the most consistent evidence is the Mediterranean diet: abundant vegetables, fruits, legumes, whole grains, nuts, olive oil, fish, and moderate amounts of poultry and dairy. Red meat and processed foods are eaten rarely.
This isn't about tracking macros or counting calories — it's a food pattern. Practically: most of your plate should be vegetables, you cook with olive oil instead of vegetable oil, you eat fish 2-3 times per week, and you snack on nuts instead of crisps.
For weight loss specifically, the evidence suggests that any diet you can actually stick to works. Consistency beats perfection. Some people do better with lower carbohydrate diets, others with lower fat. The key is reducing processed food intake, increasing protein (it keeps you full), and eating more vegetables.
Be sceptical of any diet claiming miraculous results. If it eliminates entire food groups unnecessarily or requires expensive supplements, it's probably not worth doing long-term.
