Weight loss after 40 and after 50

“I used to just skip dinner, and now nothing works.” Sound familiar? After 40, weight really does change differently. But the reasons are usually not the ones we think, and they can be changed.

Information checked on 2026-09-26. General information, not medical advice. How we calculate

In short: protect your muscles (protein + strength exercises), move every day, sleep and keep your calorie deficit small. After 40, strict diets especially often take muscle, not fat.

What changes after 40

  • Muscle mass slowly goes down if we don't train it. Less muscle means less energy used and a weaker body.
  • We move less every day: desk jobs, the car, being tired in the evening.
  • Sleep and stress: work, children, looking after parents. When you're short on sleep, you crave sweet things more.
  • Hormones: for women – the perimenopause and menopause (more here), for men – slowly falling testosterone.
  • Medicines: some medicines can affect your appetite or weight. Don't stop taking them on your own – talk to your doctor.

What helps: 6 principles

  1. A small deficit. 300–500 kcal, no more. You'll find your number in the calculator – it takes your age into account.
  2. Protein at every meal. For example, curd cheese (quark) or eggs for breakfast, fish or poultry for lunch, beans or lentils for dinner. The protein calculator shows your target.
  3. Strength exercises twice a week. Sit-to-stand squats from a chair, wall press-ups, exercises with a resistance band or bottles of water. You don't need a gym.
  4. A walk every day. 15 minutes after a meal is already a lot. More ideas in weight loss without exercise.
  5. Sleep. At a similar time, 7–9 hours, with less screen time in the evening.
  6. Patience. After 40, the pace is often slower. 0.25–0.5 kg a week is an excellent result.

For people over 60

In later life, what matters most is often not losing weight but keeping your muscle and strength. Unintended weight loss can be dangerous for older people. Before trying to lose weight after 65, it's worth talking to your GP. More on how Dumpli helps older people and their families – here.

When to talk to a doctor first

Before you change how you eat to lose weight, talk to your doctor first if:

  • you are pregnant or breastfeeding;
  • you have diabetes or take medicines that affect your blood sugar;
  • you have kidney disease, heart disease or another long-term condition;
  • you are under 18;
  • you have or have had an eating disorder;
  • you are losing weight without trying.

If your relationship with food worries you, you can talk to a doctor or a psychologist. If you're struggling right now, call your local emergency number or find a free helpline at findahelpline.com.

Frequently asked questions

Does your metabolism really slow down after 40?

Less than people often think. Large studies show that between the ages of 20 and 60, metabolism changes little once body composition is taken into account. What usually changes is other things: we move less, lose muscle, sleep worse and have more stress.

How much protein do you need after 50?

Older people are often advised to have about 1.0–1.2 g of protein per kilogram of body weight a day, and more when losing weight or exercising. If you have kidney disease, discuss how much protein you have with your doctor.

What's the best exercise after 50?

The one you'll do regularly. It's most useful to combine brisk walking or another endurance activity with strength exercises at least twice a week – they help you keep your muscles and bones.
