The Women’s Guide to Longevity: 5 Things That Matter More Than You Think

When we talk about longevity, the conversation often focuses on living longer.

But as a woman in my 40s, that's not really the part that interests me most.

I don't just want more years. I want more healthy years.

I want to be strong enough to travel, exercise and carry my own bags in my 70s. I want the energy to be involved with my family. I want to protect my brain, bones, heart and overall health for as long as I can.

That is the difference between lifespan and healthspan.

And the more I've learned about longevity and healthy ageing, the more I've realised that many of the things that may influence how well we age aren't particularly futuristic.

They're things we can start paying attention to now.

Here are five that I think deserve much more attention from women.

1. Muscle is about much more than how you look

For a long time, women's fitness was largely sold to us through the lens of weight.

Lose weight. Burn calories. Get smaller.

I'm much more interested in getting stronger.

We naturally lose muscle as we age, which makes maintaining it increasingly relevant to strength, mobility and metabolic health.

That has completely changed the way I think about exercise.

I'm not strength training simply because I want my body to look a certain way. I'm thinking about the woman I want to be decades from now.

Can she get off the floor easily?

Can she carry her groceries?

Can she lift her suitcase into the overhead compartment?

Can she keep doing the things she loves?

Those might not sound like traditional longevity goals, but to me, that's exactly what longevity looks like.

Worth thinking about: Instead of measuring every workout by calories burned, consider strength and muscle as things you're building for your future self.

2. Your bones deserve attention before they become a problem

Most of us don't spend much time thinking about our bones.

They're just... there.

Until suddenly bone density becomes something we're told we should be paying attention to.

But here's what I didn't really appreciate until I became more interested in healthy ageing: we build most of our bone mass relatively early in life, with peak bone mass generally reached by our late 20s to early 30s. From there, maintaining bone health becomes increasingly important as we age.

For women, this deserves particular attention because hormonal changes later in life can accelerate bone loss and increase the risk of osteoporosis.

That doesn't mean bone health is something we should suddenly start worrying about at a certain age. If anything, I've come to see it as another reason to think about longevity earlier.

Nutrition matters. So does movement and maintaining muscle and strength. Our individual risk is also influenced by things like family history, lifestyle, certain health conditions and medications.

I've started thinking about bone health in much the same way I think about other areas of preventative health.

Why wait until there's a problem before we start paying attention?

Worth thinking about: We spend a lot of time thinking about how our bodies look on the outside. Our bones are one of those things we can't see, but they're an important part of staying strong and capable as we age.

3. Heart and metabolic health deserve more attention than the scale

For years, one of the main health metrics women were encouraged to care about was weight.

But the number on the scale is only one tiny piece of information.

As I've become more interested in longevity, I've become much more curious about what's happening underneath it.

Blood pressure. Cholesterol. Blood glucose. Cardiovascular fitness. Family history.

Our health and our individual risks also change throughout our lives, which is another reason I think it's important to look beyond appearance or weight alone.

That doesn't mean we need to become obsessed with numbers or test everything imaginable.

For me, it's simply about shifting the focus from:

“What do I weigh?”

to:

“How healthy am I on the inside?”

That's a very different conversation.

Worth thinking about: Keeping up with appropriate health checks and understanding your own family history and risk factors can give you a much fuller picture than the bathroom scales ever will.

4. Nutrition isn't just about weight

This is another mindset I've had to change.

For so much of our lives, women are taught to think about food in terms of restriction.

How many calories?

How many carbs?

Will this make me gain weight?

I'm increasingly interested in a different question:

What does my body actually need?

- Protein to support muscle.

- Fibre and a variety of plant foods.

- Healthy fats.

- Vitamins and minerals.

- Enough food to support an active body.

And, where appropriate, supplements that complement rather than replace a good diet.

As a co-founder of Keeper Health, I spend a lot of time thinking about ingredients, supplementation and the emerging science of longevity. But the more I learn, the more convinced I am that there is no single magic ingredient.

Supplements make the most sense to me when they sit on top of good foundations.

Worth thinking about: Rather than only asking what you should remove from your diet, it can be useful to ask what you might need more of.

5. Sleep and recovery are part of the longevity conversation too

Sleep is probably one of the least exciting longevity strategies.

There is no fancy equipment required. No complicated protocol.

But the older I get, the more obvious its importance becomes.

I notice the difference when I haven't slept properly. My energy changes. Training feels harder. I'm hungrier. My concentration isn't as good. And I don't recover as well.

I've stopped thinking of rest as something that happens after everything else is finished.

There will always be another email, another job, another load of washing or another episode to watch.

Sleep has to earn its own place on the list.

Worth thinking about: Pay attention to what consistently helps or disrupts your sleep and recovery. Sometimes the least glamorous habits are the ones worth protecting most.

What I actually want from longevity

When I put all of this together, I realise that my definition of longevity has changed.

I don't spend much time thinking about whether I'll live to 100.

I think about capability.

I want to move well.

Think clearly.

Have energy.

Travel.

Work if I choose to.

Stay socially connected.

Have the energy to enjoy my family for decades to come.

And remain independent for as long as possible.

That's why muscle matters.

That's why bones matter.

That's why heart and metabolic health matter.

That's why nutrition, sleep and recovery matter.

I'm not interested in trying to stay 30 forever.

I want to see what 50, 60, 70 and beyond can look like when we start investing in our health earlier.

Because maybe the most useful way to think about longevity isn't simply:

How do I live longer?

It's: What can I do today to give myself the best chance of living well later?

And for me, that's a much more interesting conversation.
