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.
How to Create and Use a Printable Weight Loss Chart
An effective weight loss chart records your starting weight, target weight, and weekly or monthly measurements. NHS guidance recommends losing weight at a rate of 0.5 to 1 kg (1 to 2 lbs) per week for sustainable results. Your chart should include columns for date, weight in both stone and kilograms, and progress percentage.
To set realistic targets, use our free BMI calculator above to determine your healthy weight range. For an adult of average height, a healthy BMI falls between 18.5 and 24.9. Your GP can advise on a personal weight loss goal based on your current health status and weight-related conditions.
- Record your weight consistently (same day, same time, ideally weekly)
- Track both kg and stone for UK context
- Calculate percentage weight loss: (starting weight − current weight) ÷ starting weight × 100
- Celebrate milestones at 5%, 10%, and 15% loss

Weight Loss Charts for Different Approaches
Your chart structure depends on your weight loss method. If using prescription weight loss medication like semaglutide (Wegovy) or tirzepatide (Mounjaro), you may want to record your medication dose alongside weight to see how each dose adjustment affects progress. Clinical trials show participants on these medications lose an average of 15–21% of body weight, though individual results vary significantly.
For general weight loss through diet and exercise alone, a simple weekly tracker with date and weight is sufficient. Our free progress tracker on this page makes logging easier. If combining lifestyle changes with medication, track both separately so you understand which factors most support your progress. Many people find visual charts motivating — plotting progress on a graph makes success tangible.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What should I include on my weight loss chart?
Include date, current weight (in both stone and kg), percentage of body weight lost, and notes on diet or exercise changes. If using medication, record the dose. This helps you see patterns and understand what works. Our progress tracker automates much of this.
How often should I weigh myself?
Weekly weighting is ideal — ideally on the same day and time. Daily weighing can be misleading due to natural fluid fluctuations. NHS guidance supports weekly or fortnightly weighing as a sustainable approach for long-term tracking.
What's a realistic weight loss target to put on my chart?
NHS recommends losing 0.5 to 1 kg per week. On a monthly chart, expect 2 to 4 kg loss. If using GLP-1 medication, average loss is higher — approximately 15–21% of body weight over several months, though individual results vary.
Can a printable chart work if I'm taking Wegovy or Mounjaro?
Yes. Both prescription medications work alongside diet and exercise. Chart your weight weekly and note which dose you're on. This helps you and your prescriber see how your body responds. Many people find this motivating during treatment.
What weight should I aim for?
Use our free BMI calculator to find your healthy weight range for your height. A healthy BMI is 18.5 to 24.9 for most adults. Your GP can discuss a realistic personal target based on your health, genetics, and circumstances. Even a 5–10% loss brings health benefits.
