Follow the same routine when you serve meals to ensure you put together a healthy meal. Start by filling a third of your plate with veg or salad, then fill the next third with starchy foods like potato, rice, bread or pasta. Fill half of the remaining space with low-fat, protein-rich foods like meat, fish, chicken, eggs or beans. Reserve the final space for low-fat dairy products such as a glass of semi-skimmed milk, lower-fat cheese or low-fat yogurt. Just make sure you don't pour them on the rest of your food!
