BMI, or Body Mass Index, is a calculation used by healthcare professionals and the general public to determine whether or not you’re at a healthy weight. Although it sounds complicated, the equation used is quite simple – your weight in KG, divided by your height squared (BMI = KG/m2).
For most adults, the ideal BMI is between 18.5 and 25. The calculator above can work this out for you, while also giving you some other important metrics so as BFP (Body Fat Percentage – what percentage of your weight is fat) and BMR (Basal Metabolic Rate – how many calories you need to maintain your current weight).
BMI on its own can’t be used as a reliable diagnostics tool – it should always be interpreted as part of the bigger picture. Athletes for example, may have a high BMI although a low Body Fat Percentage because muscle is heavier than fat. Ethnic groups can also be impacted differently based on the BMI calculation. Pregnancy is another instance where BMI should not be solely relied upon.
Waist size is also something that should be considered alongside BMI when trying to gain a better understanding of your body. Men should aim to lose weight if their waist size is greater than 37 inches while for women it would be 31.5 inches.
As with anything medical or clinical, it’s always best to consult your doctor if you’re concerned but our BMI calculator can help you along your journey and assist you in tracking your performance and improvement.
Being underweight may be a sign you’re not eating enough food for your body composition, or that there could be other underlying health conditions. If you’re underweight, it’s recommended that you consult your GP.
