Frequently Asked Questions
1. How accurate is this BMI calculator?
Our calculator uses the standard Body Mass Index formula recognised by the NHS and World Health Organization. It’s a useful screening tool to estimate whether you are within a healthy weight range for your height. However, BMI doesn’t measure body fat directly and may not be suitable for everyone, such as athletes or those with high muscle mass.
2. What should I do if my BMI is outside the healthy range?
If your BMI is too high or too low, it may indicate a need for lifestyle changes or further health checks. Speak to your GP for personalised medical advice. Our online dietetic assessment can help you create a tailored plan to reach a healthier weight, reduce your risk of type 2 diabetes, and improve overall wellbeing. For more information, please see our Services page to get started.
3. Can a registered dietitian help me manage my weight?
Yes. A UK registered dietitian is a healthcare professional trained to provide personalised, science-based advice. We can help you improve your eating habits, activity levels, and lifestyle in a way that works for you.
