Eat smaller portions but more frequently to boost metabolism and lose weight effectively. Specifically, eat at least 5-6 times per day with 3 main dishes and 3 snacks, including an omelette or boiled egg for breakfast, fruit for a morning snack, fish and brown rice for lunch, roasted meat for an afternoon snack, beef and vegetables for dinner, and milk before sleeping. Frequent smaller meals throughout the day helps metabolism more than eating less at fewer sittings.
