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.
Why Prawns Are Great for Weight Management
Prawns are one of the leanest protein sources available. A 100g serving contains around 24g of protein but only 99 calories and less than 1g of fat, making them ideal for reduced-calorie eating. Protein helps you feel full longer, which naturally reduces overeating—particularly valuable if you're managing your weight UK through diet or taking prescription weight loss medication like Mounjaro or Wegovy.
Prawns also contain minerals like selenium and iodine, supporting metabolism and thyroid function. They're quick to cook—ready in minutes—so they fit easily into busy weekdays. Unlike many animal proteins, prawns have minimal saturated fat, making them heart-healthy too. For weight loss medication users, adequate protein intake is especially important to preserve muscle mass during weight loss. Try using our GLP-1 weight loss calculator to estimate your potential results and plan meals accordingly.
