Being overweight or obese can lead to health conditions such as type 2 diabetes, certain cancers, heart disease and stroke. Being underweight could also affect your health.

If you're trying to lose weight, aim to eat less and be more active. Eating a healthy, balanced diet will help: aim to cut down on foods that are high in fat and sugar, and eat plenty of fruit and vegetables.

Physical activity can help you to maintain weight loss or be a healthy weight. Being active doesn’t have to mean hours at the gym: you can find ways to fit more activity into your daily life. For example, try getting off the bus one stop early on the way home from work, and walking. Being physically active may help reduce the risk of heart disease, stroke and type 2 diabetes. For more ideas, seeGet active your way. After getting active, remember not to reward yourself with a treat that is high in energy. If you feel hungry after activity, choose foods or drinks that are lower in calories but still filling. 6.Don't get thirsty We need to drink about 1.2 litres of fluid every day to stop us getting dehydrated. This is in addition to the fluid we get from the food we eat. All non-alcoholic drinks count, but water, milk and fruit juices are the most healthy. Try to avoid sugary soft and fizzy drinks that are high in added sugars and can be high in calories and bad for teeth. When the weather is warm, or when we get active, we may need more.

In fact, research shows that eating breakfast can help people control their weight. A healthy breakfast is an important part of a balanced diet, and provides some of the vitamins and minerals we need for good health. Wholemeal cereal, with fruit sliced over the top is a tasty and nutritious breakfast.
