I didn’t think I’d be writing this.  But the data doesn’t lie.

.

Over the past two weeks, three of us — very different bodies, very different lifestyles — ran a simple experiment.

.

🍽️ No crazy dieting.
💊 No pills.
💦 No suffering.

.

Just a couple of controlled changes.

And what we found… might change how you think about fat loss completely.

.

THE SET-UP

.

Right now, we’ve been walking around like human science experiments.

Each of us wearing:

.

..........🩸 A Continuous Glucose Monitor (CGM)

..........🩸 A Continuous Ketone Monitor (CKM)

.

In simple terms:

👉 We can see, in real time, whether our body is running on sugar… or fat

.

WHY THIS EVEN MATTERS

.

Most people still believe fat loss comes from:

.

..........⚖️ Training harder

..........⚖️ Sweating more

..........⚖️ Eating less

.

But the body doesn’t work like that.

.

👉 You don’t burn fat because you try harder…
👉 You burn fat when the body allows it

.

THE SIMPLE VERSION (FOR MOST PEOPLE)

.

..........✅ High glucose → insulin up → fat burning OFF

..........✅ Low glucose → insulin down → fat burning ON

..........✅ Ketones present → body using fat for fuel

.

So instead of guessing… 📈 We measured it.

.

 

.

THE CREW

.

👱‍♂️ Me — 55, still moving ok… a few wobbly bits

👩 Jessica – 52, structured lifestyle, hormonally dynamic (adaptative)

👩‍🦱 Wilko – 38, roofer, 8-hour physical days

.

Three very different humans.

.

SO… WHAT DID WE FIND?

.

👉 First surprise:

.

Even with ~30% more morning exercise… fat-burning signals 'didn’t' increase during the day.

.

Let that land.

.

DURING THE DAY (INCLUDING EXERCISE)

.

Across all three of us:

.

.......... • Glucose stayed the same or even went UP a tad

.......... • Ketones stayed LOW

.

👉 Meaning:

Your body is mostly in performance mode - Not pure fat-burning mode

.

“When Does Fat Burning Actually Happen?”

 

.

Now here's where it gets interesting...

.

DURING THE NIGHT (SLEEPING SOUNDLY)

.

All three of us showed:

.

.......... • Lower glucose

.......... • 3x–5x higher ketones (ketones are the lipids broken down to fuel energy)

.

Meaning👉 A clear shift into fat-burning mode

.

 

“Same People. One Change. Big Shift.”

.

LET ME SAY THAT AGAIN

.

We trained. We worked. We moved more than usual.

But…

👉 We burned the most fat while we were asleep

.

WHY THIS HAPPENS

.

When you:

.

.......... • Eat late

.......... • Eat carbs at night

.......... • This can often influence sub-optimal sleep

.

👉 Your body stays in sugar-burning mode

.

When you:

.

.......... 👉 Eat early - Remove carbs at night

You create:

.

.......... • Low insulin

.......... • Low glucose

.......... • Rising ketones

.

👉 The perfect environment for fat burning

.

.

.

THE REAL TAKEAWAY

.

This isn’t about:

.

..........❌ “Exercise doesn’t work”

.

Because it absolutely does:

.

......... 👉 Fitness

..........👉 Strength

..........👉 Longevity

..........👉Mental health (extraordinary gains)

.

But if your goal is:

.

👉 Fat loss

.

Then this matters:

👉 Your body burns fat when the conditions allow it — not when you’re working hardest

.

FINAL WORD

.

I should also add that, for each of us, across the 1–2 nights where we experienced poorer sleep, our ketone levels dropped.

❄️ Winter rolls in…

.

Cold mornings. Dark afternoons. Motivation dips.

.

But here’s the flip...

.

.👉 Winter is the BEST time to rebuild strength, tone, and consistency — without the pressure of “summer ready.”

🔧 Sitting for hours on end — particularly when highly focused — can become a postural disaster.

🔧 Jammed hips, tight lower back, guitar-string hamstrings… and a pain in the neck!

🔧 I find that if I don’t break up this cycle, not only do I feel it physically, but mentally, I start drifting off the mark as well.

Here’s my “Super Six” go-to reverse-sitting loosen-up routine.

If practical, find yourself a little 1 x 1 space and give them a whirl - holding each stretch on both sides for 10-30 seconds.
