Is 148 Lbs (67.1 kg) a Healthy Weight?
Whether 148 lbs is a healthy weight depends entirely on your height. At 148 lbs (67.1 kg), someone who is 5ft 8in (173 cm) tall would fall within the healthy weight range according to NHS guidelines, while someone shorter or taller may be classified differently. The best way to understand if this weight is healthy for you is to check your personal BMI using our free BMI calculator above, which takes your exact height into account alongside NHS thresholds.

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 Common Heights
148 lbs converts to 67.1 kg — a weight that falls into different BMI categories depending on your height. Here are concrete examples showing how this weight compares to NHS healthy weight ranges at typical UK heights:
- At 5ft 4in (163 cm): 148 lbs gives a BMI of 25.4 — just above the healthy range (18.5–24.9), classified as overweight
- At 5ft 8in (173 cm): 148 lbs gives a BMI of 23.2 — comfortably within the healthy range
- At 5ft 11in (180 cm): 148 lbs gives a BMI of 20.6 — well within the healthy range
To find your personal healthy weight range using the kg to stone conversion method: multiply your height in metres by itself, then multiply by 18.5 and 24.9. This gives your lower and upper healthy bounds according to NHS BMI categories.

How to Know If Your Weight Is Healthy for You
BMI is a useful first screening tool, but it doesn't tell the whole story. The NHS also recommends checking your waist circumference: for men, a waist over 94 cm (37 inches) indicates increased health risk, and over 102 cm (40 inches) indicates high risk. For women, these thresholds are 80 cm (31.5 inches) and 88 cm (34.5 inches) respectively. If you're outside the healthy weight range for your height, or if you have concerns about your weight and health, speak to your GP. They can assess your individual situation, consider your family history and medical conditions, and provide personalised guidance — not just a number on the scales.
