Healthy weight-loss diet (part 3)

To maintain good health, we need to eat a variety of foods from the five food groups. Eating them in the right proportion 

will help to keep your weight under control.

A sensible rate of weight loss is around 0.5kg to 1kg (1lb to 2lb) a week. To achieve this, you need an energy deficit of 3,500kcal to 7,000kcal a week, which means eating 500 to 1,000 fewer calories a day. You can do this by replacing high-fat foods with those that are low in fat such as fruit, vegetables, unrefined carbohydrates and lower-fat dairy products, and by being more physically active. It's also important to watch the size of your portions. This can be difficult, because over time you can lose touch with what's a sensible amount of food.

Fruit and vegetables

Fruit and vegetables provide essential nutrients such as vitamins and minerals, and contain many other compounds associated with good health.

Everyone should aim to increase the amount of fruit and vegetables in their diet.

Because fruit and vegetables are bulky and contain a lot of water, they can help to control your calorie intake. Aim for at least five portions a day.

A portion weighs about 80g and can include fresh, canned, frozen and dried fruit and vegetables. A portion is equivalent to:

• Two large tablespoons of vegetables, such as peas, carrots, swede or broccoli
• Whole fruits, such as one apple, one orange, one pear
• A handful of grapes
• Two tablespoons of strawberries or raspberries
• One small glass of fruit juice
• A handful of dried fruit
