5 FACTS ON...

1 Weight loss should be slow and steady – not a quick crash. Eating 500-600 fewer calories a day will help shed 1-2lbs a week.

2 Adults should do at least 150 minutes of moderate exercise every week. Over-65s or anyone with a medical condition, should speak to their GP first.

3 Men need an average 2,500 calories daily and women 2,000. Calories measure the amount of energy in food and drink – the more active you are, the more energy and calories are burned.

4 Drinking sensibly can help healthy weight loss – no more than 14 units per week for men and women.

5 Eating healthily is key to weight loss. Eat more fruit and veg – at least five a day or seven if you have high blood pressure – and reduce saturated fat intake.
