What We’ll Cover:
Muscles do much more than help you exercise. They help you move, lift, carry shopping, climb stairs and stay independent.
Looking after your muscles is important at every age, especially during weight loss. When you lose weight, the aim is to lose body fat while keeping as much muscle as possible.
Muscle also supports your balance, posture and strength. Keeping your muscles healthy can make everyday activities feel easier now and as you get older.
It is normal to slowly lose muscle as we get older. This natural loss of muscle is called sarcopenia.
Some things can increase the risk of losing muscle, including:
People taking GLP-1 medicines often eat less because they feel fuller. This can make it harder to get enough protein, so including protein regularly and staying active becomes even more important.
1. Eat enough protein
Include a source of protein with each meal where you can.
Examples include:
For more ideas, read our Practical Guide to Protein.
2. Stay active
Walking is great for your health, but your muscles also benefit from activities that make them work a little harder too.
Strength exercises help keep muscles strong and can also support your balance as you get older.
You do not need to join a gym. Try:
Aim to include strength-based activities at least twice a week if you can.
Small amounts of activity done regularly are more helpful than doing lots of exercise once in a while.
3. Support your bones
Muscles and bones work together to keep you strong and active. Including enough calcium and vitamin D, alongside regular strength-based activity, helps support healthy bones and muscles.
Vitamin D comes mainly from sunlight, and some people may need a supplement during the autumn and winter months or throughout the year. If you are concerned about your vitamin D levels or think you may be at risk of deficiency, speak to your healthcare professional for advice.
For more information, read our Practical Guide to Calcium.
Looking after your muscles is an important part of healthy ageing and successful weight loss. Protecting your muscles can help you stay strong, active and independent.
Eating enough protein, staying active and including strength-based activities can all help protect your muscles.
Small habits today can make a big difference to your future health.
