💥 Does Your Metabolism Really Slow Down with Age? Here’s the Truth

We’ve all heard it — “Your metabolism slows down after 40.”

But here’s the thing… that’s only half true. And I’m about to tell you the bit no one explains properly.

💬 First, let’s clear up the myth

A big international study published in Science (2021) looked at thousands of people aged from babies to 95 years old. They found that your metabolism — the number of calories your body burns to keep you alive — stays surprisingly stable from your 20s right up to your 50s!

So no, your metabolism doesn’t suddenly fall off a cliff just because you’ve had a few birthdays 🎂

💪 The real reason it feels slower

As we get older, we naturally lose muscle (that’s called sarcopenia).

And muscle is your body’s metabolic engine — it burns more calories, even when you’re resting.

Less muscle = less energy burned = “my metabolism feels slower.”

Add in less daily movement, more sitting, and a few hormonal changes… and there you have it — not a broken metabolism, just a body that needs a little strength boost!

⚡ The good news

You can absolutely turn this around.

Here’s what keeps your metabolism firing:

✅ Strength training (lifting weights, resistance bands, bodyweight workouts)

✅ Moving more throughout the day

✅ Getting enough protein

✅ Sleeping and recovering well

Basically — keep those muscles alive, active, and challenged.

🌟 Quick takeaway

Your metabolism doesn’t slow down because you’re older.

It slows because you lose muscle — and that’s something you can totally change.
