Your BMI is just part of the story. Health risks such as diabetes and heart problems vary depending on where any excess fat is stored. Fat around the tummy or belly causes more health problems than fat in other places, such as your bottom or thighs

Weight loss needs to be done steadily and sustainably. To lose 1lb a week, reduce your daily calorie intake by 500 calories. Seek medical advice about your target weight and how to achieve it.

If your BMI result suggests you are underweight, do not attempt to lose more weight and seek medical advice.

Managing your weight is about balancing the fuel you take on board through calories in food and drink with the calories you burn through everyday activities and exercise.

UK guidelines recommend taking 150 minutes of exercise a week to maintain health. Do least 150 minutes (2 hours and 30 minutes) of moderate-intensity aerobic activity such as cycling or fast walking every week, and muscle-strengthening activities on 2 or more days a week that work all major muscle groups - legs, hips, back, abdomen, chest, shoulders and arms.
