What is a Healthy Weight?

The most common way of measuring if you’re a healthy weight for your height is to calculate your body mass index (BMI). It can also be useful to look at your waist circumference, which gives a better idea of where you store fat on your body. 

BMI (body mass index)

BMI is used to estimate if you’re a healthy weight for your height.

You can work out your BMI using our BMI calculator.

BMI is classified as follows.

  • Less than 18.5 = underweight
  • 18.5–24.9 = healthy weight
  • 25–29.9 = overweight
  • 30– 39.9 = obese
  • Over 40 = morbidly obese

As your BMI increases, so does your risk of various diseases.

BMI Healthy Weight Calculator


To find out if you’re a healthy weight for your height, work out your body mass index (BMI).

You can easily check your BMI by using this BMI calculator. A BMI between 18.5 and 24.9 is considered healthy.

The BMI calculator can also be used to check if you or your child is a healthy weight.

But that doesn’t mean you have to totally blow your healthy eating plan this festive season.Check out our new alternative healthy recipes to traditional festive favourites that taste delicious  but are far better for you.

Three reasons to eat well


BMI is a measure that adults can use to see if they are a healthy weight for their height. For most adults, an ideal BMI is between 18 and 25. If your BMI is over 25, you weigh more than is ideal for your height.


You can also attend a free informative, two hour, Healthy Eating Workshop covering a range of subjects designed to motivate, energise and educate towards making small changes around healthier eating.


Eating healthily can cost less than you might think. There are plenty of healthy options available which will not just help you to live a healthier lifestyle but will also help your bank balance.
