Addressing obesity

How much weight do you need to lose to improve your health?

A modest weight loss of 5%-10% can help improve your health and reduce the risk of obesity-related diseases including: 

  • Type 2 diabetes
  • Heart disease
  • High blood pressure
  • Bad cholesterol
  • Sleep apnoea

While healthy eating and physical activity should always be part of your weight loss efforts, they are not always enough to keep off any weight that you have lost. This is why it is important to work with your healthcare professional to develop a comprehensive and individualised approach to obesity and weight management. 

About your BMI

Knowing your current weight and BMI, and evaluating your weight loss history, can help you and your healthcare professional develop a weight loss plan.

Your body mass index (BMI) is worked out by dividing your body weight (kilograms, kg) by the square of your height (meters, m)2

BMI = body weight (kg)
              height (m)2
