What is 79 kg in stone and pounds?
79 kilograms converts to 12 stone 5.6 pounds (or 12st 5.6lbs). However, whether this is a healthy weight depends entirely on your height. Using our free BMI calculator above, you can see what BMI this weight gives you and where you fall on the NHS weight categories. BMI is a useful screening tool, though it has limitations — it doesn't account for muscle mass or where fat is stored on your body. Let's explore what 79kg means for your health at 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.
79 kg BMI at Different Heights
BMI depends on both weight and height, so 79kg creates different BMI values depending on how tall you are. Here are examples at common UK heights:
- 5ft 4in (163cm): BMI of 29.8 — falls in the overweight category
- 5ft 6in (168cm): BMI of 27.4 — falls in the overweight category
- 5ft 8in (173cm): BMI of 26.5 — falls in the overweight category
- 5ft 10in (178cm): BMI of 25.4 — falls in the overweight category
- 6ft 0in (183cm): BMI of 23.6 — falls in the healthy weight range
- 6ft 2in (188cm): BMI of 22.3 — falls in the healthy weight range
As you can see, at 79kg, taller individuals are more likely to fall into the healthy weight category, while shorter individuals may be classified as overweight. This is why height matters so much when assessing weight health.

Understanding NHS Weight Categories
The NHS uses standardised BMI categories to classify adult weight status. A healthy BMI is between 18.5 and 24.9. If your BMI from 79kg falls into the overweight range (25.0–29.9), it means your health risks from excess weight are starting to increase, though you're not yet in the obese category. For adults of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends lower thresholds because these groups face higher health risks at lower BMI levels. Try our weight converter to check 79kg against your exact height, then use the BMI calculator to get your personal result and health recommendations from your GP.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 79 kg in stone and pounds exactly?
79kg equals 12 stone 5.6 pounds (12st 5.6lbs). To convert kilograms to stone, divide by 6.35029. To convert to pounds only, multiply 79 by 2.20462, which gives 174.1 pounds. Our weight converter tool above lets you switch between all these units instantly.
Is 79 kg a healthy weight?
It depends on your height. At 79kg, a person who is 6ft tall would have a healthy BMI of around 23.6. Someone 5ft 4in would have a BMI of around 29.8, which is overweight. Use our free BMI calculator to find your personal result based on your exact height.
What BMI does 79 kg give at 5ft 8in?
At 5ft 8in (173cm), a weight of 79kg gives a BMI of approximately 26.5, which falls into the overweight category according to NHS guidelines. The healthy weight range for this height is roughly 55–73kg.
How much weight would I need to lose from 79kg to be healthy?
If you're in the overweight category, losing 5–10% of your body weight (approximately 4–8kg) can bring meaningful health benefits, according to NHS guidance. For someone at 79kg, this means aiming for around 71–75kg. Your GP can advise on a safe, sustainable target for your height and health profile.
Are there limitations to using BMI?
Yes. BMI doesn't distinguish between muscle and fat — athletes may have a high BMI but low body fat. BMI also doesn't account for where fat is stored (waist circumference matters too) or age-related muscle loss. Always discuss your personal weight and health with your GP for tailored advice.
