eating well your weight wise plan


If you prefer a structured approach to weight loss, this section is for you. You don't have to count calories, and you don't have to weigh your food. Using the 'Balance of Good Health' we've worked out how many servings or portions you need from each food group, to make up a range of daily calorie (energy) requirements.

Please note: these calorie ranges are NOT designed for people under 18 years, breastfeeding or pregnant women. Also, if you have any medical problems, it's best to seek the advice of your doctor before embarking on any structured weight loss programme.

How many calories do you need?

We all have different needs, depending on: age, gender, activity levels and body weight.

Your energy requirements will probably be higher the younger and fitter you are. If you are overweight, your energy input is higher than someone who is a healthy weight. So, to lose weight you need to take in fewer calories and/or be more physically active.

Ideally, you need to eat 500-600 calories fewer than your daily calorie needs in order to lose a healthy 0.5kg/1lb per week - you may lose more if you're more active too.

Most women will lose about this amount of weight on 1500 calories and most men on 1800 calories. That's why we've chosen these in the following examples. Using the food groups, we've worked out how many servings to have each day to make up these calories in a healthy balanced diet.

Daily calorie ranges and servings from each group

Food group 1500 calories 1800 calories
  Starchy   7   8
  Fruit   3   4
  Vegetables   3   4
  Milk   2   2
  Meat/alternatives   2   2
  Fat   3   4
  Extras/snacks   150 calories   200 calories
Note: kcal is the technical term for calorie. They mean the same. 1kcal = 4.2 kilo joules (kJ), which you see on nutrition labels.

  • For more about serving sizes of fruit and vegetables for good health, go to the 5 A Day section on the Department of Health's website at:

Meat, Fish and Alternatives

  • Use smaller amounts of stronger-flavoured cheese in cooking

Mixed meals

What about meals made up of a mixture of foods such as pizza or lasagne? How do you decide on the serving size? All you have to do is break the meal down into its main ingredients e.g.

Pizza and salad

Main ingredients Portions / serving sizes
Dough base 2 starchy servings
Mushrooms, tomatoes, peppers 1 vegetable serving
Ham 1 meat servings
Cheese 1 milk and dairy serving
Side salad 1 vegetable serving
Dressing (1 teaspoon) 1 fat serving

The good news about the Weight Wise plan is you can still enjoy the foods you like best, with no rigid meal plans to worry about. Just mix and match your portions from each group, remembering to keep a diary along the way, to help you keep on track.
