Nutrel's advice based on your BMI
(Disclaimer: It is best to see a qualified doctor)


After you have calculated your BMI score, this chart from Nutrel will help you work out if your weight is likely to cause a health risk

Find your score on the BMI graph and the health risk for which it is assessed. For example, a BMI score of 20 - 25 is associated with the lowest health risk based solely on BMI scores. If your score is over 27, you are considered to be at increased risk for health problems that are negatively impacted by obesity, such as diabetes, heart disease, high cholesterol or hypertension. Exceptions to a high BMI score include competitive athletes and body builders, whose BMI is high due to increased muscle mass, and women who are pregnant or lactating. The BMI is also not intended for use in measuring growing children or elderly individuals.

If your BMI and body weight are low, you should consider gaining weight through good diet and exercise habits to increase your muscle mass.
