Have healthy meal portions
Explain to your child how to get the balance of their diet right using The Eatwell Guide – it shows how much (the proportion) of what we eat overall should come from each food group. Always aim for your 5 A Day.
All you need to know about calories for the whole family
Calories are a measure of the amount of "energy" in food and drinks. Having a rough idea of how many calories your child has each day, and balancing that with the amount of physical activity they do, will help them reach and stay at a healthy weight.
Remember, we don't all need to eat the same amount of calories – children need less than adults. So keep an eye on portion sizes and offer "me-sized meals" for kids. For example, a five-year-old needs less than a 10-year-old, and a 10-year-old needs less than a grown-up.
The rule of thumb for calories is simple! Just eat:
So remember: 400-600-600
That leaves you with just enough left over to enjoy a few healthy drinks and snacks throughout the day.
Women should aim to eat no more than 2,000kcal each day, men 2,500kcal. Using calories as a guide is the easiest way to make healthier food choices and to make sure we're not eating too much.
