Weight Loss After 60 — What You Need to Know
Losing weight after 60 is entirely possible and can bring significant health benefits — but it does require a different approach than younger adults. As we age, metabolism naturally slows, muscle mass decreases, and hormonal changes affect how our body manages weight. The good news is that even modest weight loss (5–10% of body weight) can improve blood pressure, blood sugar control, joint health, and mobility. NHS weight loss guidance applies to all ages, and your GP can help you find an approach that suits your individual health needs and circumstances.

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 Weight Loss Gets Harder After 60
Several natural changes happen as we age that make weight management more challenging:
- Slower metabolism: Your body burns fewer calories at rest after 60 due to declining muscle mass and hormonal changes
- Muscle loss (sarcopenia): Without regular strength exercise, we lose approximately 3–8% of muscle mass per decade after age 30, accelerating after 60
- Hormonal shifts: Changes in oestrogen, testosterone, and other hormones affect how fat is stored and distributed
- Medication effects: Some common medications for blood pressure, heart conditions, or arthritis can slow weight loss or increase appetite
- Reduced activity: Joint pain, reduced mobility, or health conditions may mean less physical activity than in earlier years
Understanding these changes helps you set realistic expectations and choose sustainable strategies. Weight loss isn't impossible after 60 — it just requires patience, consistency, and often professional support from your GP or a weight management specialist.

Safe Weight Loss Strategies for Over 60s in the UK
The NHS recommends losing weight at a rate of 0.5–1 kg per week for all adults, including those over 60. Focus on:
- Protein intake: Eating adequate protein (1.0–1.2g per kg body weight) helps preserve muscle during weight loss
- Strength training: Regular resistance exercises twice weekly can slow or reverse muscle loss and boost metabolism
- Consistent activity: Aim for 150 minutes of moderate activity weekly — walking, swimming, or cycling are joint-friendly options
- Medical support: Your GP can assess underlying health conditions, review medications, and refer you to NHS weight management services if needed
- Prescription options: For adults with a BMI of 30 or above, or 27+ with weight-related health conditions, GLP-1 weight loss medication may be appropriate alongside lifestyle changes

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Is it safe to lose weight after 60?
Yes, weight loss after 60 is safe and beneficial when done gradually. The NHS recommends losing 0.5–1 kg per week. However, always consult your GP first, especially if you take medications or have underlying health conditions. Your GP can assess what's appropriate for you personally.
How much weight should I aim to lose?
Even a 5–10% reduction in body weight brings measurable health benefits — improved blood pressure, better blood sugar control, and reduced joint pain. Rather than focusing on a specific target, work with your GP on realistic milestones. Use our free progress tracker to monitor your journey.
Can I use weight loss injections if I'm over 60?
Yes. GLP-1 medications like Wegovy (semaglutide) are approved for adults over 60 with a BMI of 30 or above, or 27+ with weight-related conditions. Clinical trials included older adults. A prescriber will assess your individual health and suitability. These medications work alongside, not instead of, lifestyle changes.
How do I check if I'm overweight?
Use our free BMI calculator on this page to find your personal BMI. For adults, a healthy BMI is 18.5–24.9 according to NHS guidelines. Your GP can also discuss whether your weight poses health risks specific to your circumstances.
What's the best diet for weight loss after 60?
The best diet is one you can sustain long-term. Evidence supports Mediterranean diets, lower-calorie eating (creating a 500 kcal daily deficit for ~0.5kg weekly loss), and intermittent fasting. Your GP or a registered dietitian can advise on what suits your health conditions and preferences.
