Is 72.5 kg a Healthy Weight?
72.5 kg equals 159.8 pounds — but whether this is a healthy weight for you depends entirely on your height. The same weight can be healthy for a tall person and overweight for someone shorter. Using NHS guidelines and a simple BMI calculation, you can discover exactly where your weight sits relative to healthy ranges. This guide shows you how, with practical examples for different heights.

What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Healthy Weight Ranges at Different Heights
At 72.5 kg (159.8 lbs), your health status depends on your height. Here are three real examples showing how the same weight produces very different health outcomes:
- If you are 5ft 10in (178 cm): 72.5 kg gives a BMI of 22.9 — this falls in the healthy weight range (18.5–24.9). Your weight is appropriate for your height.
- If you are 5ft 6in (168 cm): 72.5 kg gives a BMI of 26.8 — this is in the overweight category (25–29.9). You may benefit from weight loss to reach a healthier range.
- If you are 5ft 2in (157 cm): 72.5 kg gives a BMI of 29.5 — this is in the overweight category, closer to obese. A GP or weight management service could discuss options.

NHS Healthy Weight Guidance and Next Steps
According to NHS guidelines, a healthy BMI is 18.5 to 24.9 for most UK adults. However, the NHS also recommends measuring waist circumference alongside BMI: men over 94 cm (37 inches) and women over 80 cm (31.5 inches) face increased health risk, even at a healthy BMI. If you fall outside the healthy weight range for your height, the NHS recommends speaking to your GP. Your doctor can assess your individual health, discuss weight loss approaches, and check whether factors like blood pressure, blood sugar, or cholesterol are affected. Remember: healthy weight varies by frame size, muscle mass, and genetics — your GP provides personalised guidance based on your complete health picture.
