The physician Dr Sara Gottfried has devised the Healthspan Score, her method of measuring how quickly you’re ageing — and how to slow it down. Answer the questions and see how you rate.
Demographics
1 Are you . . .
female = 1 point
male = 0 points
2 Age
Under 40 = 2 points
40−65 = 1 point
Over 65 = 0 points
3 What’s your waist size (measure waist circumference at belly button)?
If female, less than 88cm (35in) = 2 points
88cm (35in) or greater = 0 points
If male, less than 102cm (40in) = 2 points
102cm (40in) or greater = 0 points
4 Let’s calculate your present BMI
Enter height in metres or inches:
Enter weight in kg or pounds:
Use a calculator, or the formula BMI = weight ÷ height2.
If you used kilograms and metres, you have your result. If you used pounds and inches, you need to multiply the result by 703. For example, for a woman who is 150lb with a height of 64in, BMI = (150 ÷ 642) × 703 = 25.7
BMI less than 18.5 = 0 points
BMI 18.5−24.9 = 2 points
BMI 25.0–29.9 = 1 point
BMI 30 and above = 0 points

What your score means
You now have a baseline measurement of the most important factors determining your rate of ageing. Now, interpret your score.
Less than 40
Very low healthspan
You are ageing excessively. See your doctor for help.
40-49
Low healthspan
You are ageing fast and are at high risk of a compromised healthspan. There’s no time to waste.
50-59
Below-average healthspan
You are ageing moderately fast.
60-69
Average healthspan
70-79
Above-average healthspan
You are doing a lot right, but need to address several gaps.
More than 80
Excellent healthspan
You have good practices in place and need to establish them as habits, looking for the small tweaks that will improve your score.
Why do these measurements matter?
They indicate how your genes are performing. Every one of them affects your genetic expression and helps to highlight, even prioritise, the functional medicine solution. Each section reflects a key aspect of ageing, from disease risk to oxidative stress, and suggests where you need the most help.
