79kg in Lbs — Is This a Healthy Weight for You?
79 kilograms equals 174.2 pounds, but whether this is a healthy weight depends entirely on your height. The same weight can be perfectly healthy for one person and overweight for another. Using NHS guidelines, we'll show you how to check if 79kg falls within a healthy range for your height, and what to do if it doesn't. Our free BMI calculator above can help you find your exact health category in seconds.

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 79kg, your health status depends on your height. Here's how 79kg compares across common UK heights:
- At 5ft 2in (157cm): 79kg gives a BMI of 32.1 — this falls in the obese category
- At 5ft 7in (170cm): 79kg gives a BMI of 27.7 — this is overweight but not obese
- At 5ft 11in (180cm): 79kg gives a BMI of 11.0 — this is within the healthy weight range
For a healthy BMI of 18.5–24.9 at 79kg, you'd need to be approximately 5ft 9in (175cm) or taller. If you're shorter, this weight may be above the healthy range. If you're taller, it's likely healthy.

NHS Guidance: What the Weight Range Means
The NHS defines healthy weight using BMI ranges that account for both weight and height. At 79kg, you're in a position where height is critical — just a few centimetres can shift you between healthy, overweight, and obese categories.
What to do next: Measure your height accurately in centimetres, then use our BMI calculator above to find your exact BMI. If you're outside the healthy range, a simple step is checking your waist measurement — the NHS recommends under 94cm (37in) for men and under 80cm (31.5in) for women as a health marker. If you're concerned, speak to your GP, who can give you personalised guidance on weight management and health.
