If you didnโ€™t read my previous two posts, this is a continuation of something Iโ€™ve been learning about from Why We Get Sick by Benjamin Bikman, PhD.

The subject?

๐—œ๐—ป๐˜€๐˜‚๐—น๐—ถ๐—ป ๐—ฟ๐—ฒ๐˜€๐—ถ๐˜€๐˜๐—ฎ๐—ป๐—ฐ๐—ฒ ๐—ฎ๐—ป๐—ฑ ๐—ต๐˜†๐—ฝ๐—ฒ๐—ฟ๐—ถ๐—ป๐˜€๐˜‚๐—น๐—ถ๐—ป๐—ฒ๐—บ๐—ถ๐—ฎ - ๐—ฐ๐—ต๐—ฟ๐—ผ๐—ป๐—ถ๐—ฐ๐—ฎ๐—น๐—น๐˜† ๐—ต๐—ถ๐—ด๐—ต ๐—ถ๐—ป๐˜€๐˜‚๐—น๐—ถ๐—ป.

Very simply:

๐Ÿ‘‰ Insulin resistance is when your body stops responding properly to insulin.

So your body has to produce ๐—บ๐—ผ๐—ฟ๐—ฒ ๐—ฎ๐—ป๐—ฑ ๐—บ๐—ผ๐—ฟ๐—ฒ ๐—ถ๐—ป๐˜€๐˜‚๐—น๐—ถ๐—ป to get the same job done.

And this can be happening for years without you knowing.

Some common clues include:

Cravings, especially sugar and carbs
Energy crashes
Feeling hungry soon after eating
Struggling to lose fat around your middle
Brain fog / low energy

These aren't a diagnosis, but they're certainly clues.

Now, the next part of Bikmanโ€™s book really caught my attention...

๐—ง๐—ต๐—ฒ ๐—ฐ๐—ผ๐—ป๐—ป๐—ฒ๐—ฐ๐˜๐—ถ๐—ผ๐—ป ๐—ฏ๐—ฒ๐˜๐˜„๐—ฒ๐—ฒ๐—ป ๐—ถ๐—ป๐˜€๐˜‚๐—น๐—ถ๐—ป ๐—ฎ๐—ป๐—ฑ ๐˜†๐—ผ๐˜‚๐—ฟ ๐—บ๐˜‚๐˜€๐—ฐ๐—น๐—ฒ๐˜€.

And especially if you're a woman over 40, this matters.

Bikman explains that in the average middle-aged person, muscle makes up around ๐Ÿฎ๐Ÿฑโ€“๐Ÿฏ๐Ÿฌ% ๐—ผ๐—ณ ๐˜๐—ต๐—ฒ ๐—ฏ๐—ผ๐—ฑ๐˜† - making it the largest insulin-sensitive tissue we have.

Why is that important?

Because your muscles are one of the main places your body can put glucose after you eat.

Think of muscle almost like a ๐—ด๐—น๐˜‚๐—ฐ๐—ผ๐˜€๐—ฒ ๐˜€๐˜๐—ผ๐—ฟ๐—ฎ๐—ด๐—ฒ ๐˜๐—ฎ๐—ป๐—ธ.

๐Ÿ‘‰ More muscle = more room to take glucose out of your bloodstream.

And that helps your insulin levels return to normal.

But here's the problem...

Bikman explains that muscle is also ๐—ผ๐—ป๐—ฒ ๐—ผ๐—ณ ๐˜๐—ต๐—ฒ ๐—ณ๐—ถ๐—ฟ๐˜€๐˜ ๐˜๐—ถ๐˜€๐˜€๐˜‚๐—ฒ๐˜€ ๐˜๐—ผ ๐—ฏ๐—ฒ๐—ฐ๐—ผ๐—บ๐—ฒ ๐—ถ๐—ป๐˜€๐˜‚๐—น๐—ถ๐—ป ๐—ฟ๐—ฒ๐˜€๐—ถ๐˜€๐˜๐—ฎ๐—ป๐˜.

In someone with insulin resistance, muscle can be around ๐—ต๐—ฎ๐—น๐—ณ ๐—ฎ๐˜€ ๐˜€๐—ฒ๐—ป๐˜€๐—ถ๐˜๐—ถ๐˜ƒ๐—ฒ ๐˜๐—ผ ๐—ถ๐—ป๐˜€๐˜‚๐—น๐—ถ๐—ป ๐—ฎ๐˜€ ๐—ถ๐˜ ๐˜€๐—ต๐—ผ๐˜‚๐—น๐—ฑ ๐—ฏ๐—ฒ.

And it works both ways.

Insulin resistance can make it harder to maintain muscle...

While having less muscle gives your body less capacity to deal with glucose.

And we already have another problem as we get older.

According to the book, after middle age we can lose roughly ๐Ÿญ% ๐—ผ๐—ณ ๐—ผ๐˜‚๐—ฟ ๐—บ๐˜‚๐˜€๐—ฐ๐—น๐—ฒ ๐—ฒ๐—ฎ๐—ฐ๐—ต ๐˜†๐—ฒ๐—ฎ๐—ฟ.

So maintaining - and ideally building - muscle becomes increasingly important.

Not because you need to look like a bodybuilder.

But because muscle is one of your biggest tools for:

๐Ÿ‘‰ Better insulin sensitivity
๐Ÿ‘‰ Better glucose control
๐Ÿ‘‰ Staying stronger as you age
๐Ÿ‘‰ Maintaining your metabolism and independence

This is another reason why I keep banging on about ๐˜€๐˜๐—ฟ๐—ฒ๐—ป๐—ด๐˜๐—ต ๐˜๐—ฟ๐—ฎ๐—ถ๐—ป๐—ถ๐—ป๐—ด ๐—”๐—ก๐—— ๐˜„๐—ต๐—ฎ๐˜ ๐˜†๐—ผ๐˜‚ ๐—ฒ๐—ฎ๐˜.

They work together.

And this is exactly what we'll be focusing on during our
๐Ÿฐ-๐—ช๐—ฒ๐—ฒ๐—ธ ๐—ฆ๐—ฒ๐—ฝ๐˜๐—ฒ๐—บ๐—ฏ๐—ฒ๐—ฟ ๐—ฅ๐—ฒ๐˜€๐—ฒ๐˜ - resetting your eating habits, reducing unnecessary insulin spikes and learning simple ways to keep insulin at healthier levels even when you eat foods that would normally elevate it.

The signal your body keeps sending
Insulin resistance explained in plain English

After my last post, quite a few of you asked:

๐Ÿ‘‰ โ€œWhat actually is insulin resistance?โ€
๐Ÿ‘‰ โ€œHow would I know if I have it?โ€

Hereโ€™s the simple version:

Insulin resistance = your body not responding properly to insulin.

So your body produces more and more of itโ€ฆ
and insulin stays chronically high.

And remember - insulin isnโ€™t just about blood sugar.
๐Ÿ‘‰ Itโ€™s a growth signal in the body.

How do you know if you have it?

Most people donโ€™t.

It can build for years with no obvious signs.

Tests can help (fasting insulin, HOMA-IR)โ€ฆ
but theyโ€™re not always done.

So instead, look for clues:

* Cravings (especially sugar/carbs)
* Energy crashes
* Struggling to lose fat (especially around the middle)
* Hungry soon after eating
* Brain fog / low energy

Not a diagnosis - but common patterns.

Why does it matter?

Because insulin resistance is linked to:

* Type 2 diabetes
* Heart disease
* And certain cancers

The good news?

๐Ÿ‘‰ Itโ€™s one of the most controllable things for your health.

Thatโ€™s exactly what my 4-week September Reset is about:

โœ” Reset your eating habits
โœ” Lower insulin levels
โœ” Learn how to keep insulin stable
โœ” Even when you eat foods that would normally spike it

NOT WHAT YOU'D EXPECT ABOUT CANCER.

NEW BOOK CHAPTER MADE ME STOP AND THINK - THIS IS WORTH READING.

I started reading the book Why We Get Sick by Benjamin Bikman, PhD, and one chapter really made me stop.

Itโ€™s about cancer - but not in the way you might expect.

This isnโ€™t about fear.
Itโ€™s about what we can actually influence.

Because while cancer can feel randomโ€ฆ
๐Ÿ‘‰ your metabolic health isnโ€™t.

One of the strongest links discussed is between
insulin resistance (chronically high insulin) and cancers like:

โ€ข Breast
โ€ข Prostate
โ€ข Colorectal

A few facts:

โ€ข Breast tumours have 6x more insulin receptors than healthy tissue
โ€ข High insulin resistance = up to 250% higher risk of prostate cancer
โ€ข Colon cancer patients with insulin resistance are ~3x more likely to die

This matters because insulin isnโ€™t just about sugarโ€ฆ

๐Ÿ‘‰ Itโ€™s a growth signal.
And when it stays high, it can create an environment where disease is more likely to progress.

Hereโ€™s the good news:

๐Ÿ‘‰ This is something you can influence.

Not perfectly.
But meaningfully.

And it doesnโ€™t require extremes - just a simple, structured approach.

๐Ÿ‘‰ Thatโ€™s exactly what my 4-week Reset Programme https://28daybootcamp.info/ in September is designed to do.

โœ” Reset your eating habits
โœ” Lower chronically high insulin
โœ” Stabilise your energy (and fat loss)
โœ” Help you feel back in control again

No extremes.
No guesswork.

Weโ€™re halfway through 2026โ€ฆ

Be honest.

How far have you actually gotten with your New Yearโ€™s resolution?

If your goal was โ€œget fitโ€, โ€œlose weightโ€, or โ€œtone upโ€โ€ฆ

Thatโ€™s not really a goal.

Itโ€™s too vague.

And vague goals = vague results.

Think about itโ€ฆ

No successful company just says โ€œwe want to make moneyโ€.

They know exactly what theyโ€™re aiming for and by when.

And your body works the same way.

Thatโ€™s why inside my 28 Day Kickstart, the goal is simple:

Drop at least one clothing size in 28 days.

Not โ€œfeel a bit betterโ€โ€ฆ

But actually feel confident in your clothes.

Especially nowโ€ฆ

Holidays, photos, lighter outfitsโ€ฆ

No more hiding behind baggy jumpers.

And the best part?

Most people who follow the plan properly lose 7โ€“14 lbs and drop a size.

So hereโ€™s the question:

Whatโ€™s your goal for July?

Because the next 28 days will pass anyway.

You can either drift through themโ€ฆ

Or come out the other side fitter, lighter, and more confident.

The next 28 Day Body Transformation Kickstart starts Monday 6th July
๐Ÿ“ Meadowhead School (S8)
๐Ÿ“ King Edward Lower School (S10)

Youโ€™ll get:
โœ”๏ธ 12 training sessions
โœ”๏ธ Full eating plan
โœ”๏ธ Structure and accountability
โœ”๏ธ Results guarantee

08/05/2026

After sending a couple of emails this week, quite a few people have asked me about Ozempic, Wegovy and similar medications.

Mostly:

Are they safe?
What are the side effects?
And who should actually be using them?

So hereโ€™s my honest answer.

Do they work?
Yes.

These medications can reduce appetite and quiet what many describe as "food noise" - constantly thinking about food.

For some women, that alone makes a big difference.

Side effects?

The most common ones include nausea, digestive issues like constipation or diarrhoea, and occasional vomiting.

In many cases, these can be managed with proper dosing, hydration and medical guidance.

There are also more serious risks, such as pancreatitis, but these are rare.

Who are they for?

Typically, theyโ€™re prescribed in the UK for people with a BMI of 30 or above, or 27 or above if they have weight-related health conditions, such as type 2 diabetes and high blood pressure.

But in reality, thereโ€™s also a grey area.

Women who have struggled for years.

Those who feel constantly hungry.

Who are doing "everything right" but still not seeing results.

Some of them may benefit from this kind of support.

And I understand that.

But hereโ€™s the part most people ignoreโ€ฆ

๐Ÿ‘‰ If you use these medications without strength training, you will lose muscle as well as fat.

โŒ That means you get weaker.

โŒ Your metabolism slows down.

โŒ And your risk of osteoporosis and sarcopenia increases.

And it doesnโ€™t stop there.

๐Ÿ‘‰ When you come off the medication, if your habits havenโ€™t changed, you often go back to eating the same way.

โŒ The weight comes back.

โŒ And very often, it comes back as more fat, not muscle.

Thatโ€™s the cycle most people donโ€™t see coming.

So whatโ€™s the right approach?

๐Ÿ‘‰ If someone chooses to use these tools, then in my opinion:

โœ” Strength training is non-negotiable

โœ” Protein intake needs to be prioritised

โœ” And habits have to change

Otherwise, youโ€™re just delaying the problem.

Where do I stand?

Iโ€™m not against these medications.

But I am strongly against losing weight and ending up weaker.

Because what most women actually want isnโ€™t just a lower number on the scale.

They want to feel strong.

Have more energy.

Feel confident in their body again.

And that comes from building strength, not just losing weight.

๐Ÿ‘‰ If you want to do it properly, thatโ€™s exactly what we focus on inside my programmes.

โœ” Small groups.

โœ” Proper coaching.

โœ” Learning how to lift safely and confidently.

โœ” No gym intimidation.

๐Ÿ‘‰ If youโ€™re thinking about starting, reply with "STRONG", and Iโ€™ll add you to the waiting list.

Or just reply with any questions - Iโ€™m always happy to help.

You donโ€™t have to wait to get started.

While those two small groups, the 4-week Strength Training Kickstart (max 4 women in each group) in my private studio in Meersbrook S8, are currently fullโ€ฆ

Iโ€™ve got a few spaces available in our 28-Day Body Transformation Kickstart Programme starting next week:

๐Ÿ“ Sheffield S8 - Meadowhead School
๐Ÿ“ Sheffield S10 - King Edward Lower School

And yes - we do strength training there too.

Youโ€™ll be doing:

โœ” Bodyweight strength training
โœ” Resistance band strength training
โœ” Boxercise sessions (great stress buster)

Which means:

โœ” Youโ€™ll burn a lot of calories
โœ” Get fitter (fewer out-of-breath moments)
โœ” Feel stronger and more energised
โœ” And fit much better in your clothes over the 28 days

Itโ€™s fun, supportive, and results-focused.

And for many women, itโ€™s the perfect starting point before moving into small-group strength training in the studio later.

If you donโ€™t want to wait, this is your opportunity to start now.

Let me ask you somethingโ€ฆ

4 weeks from nowโ€ฆ where will you be?

Still feeling tiredโ€ฆ
Still putting yourself lastโ€ฆ
Still thinking โ€œI need to startโ€โ€ฆ

Orโ€ฆ

Feeling stronger.
More energised.
More confident in your clothes.

Because hereโ€™s the truth most women over 40 already know deep down:

Itโ€™s not that you donโ€™t want to change.
Itโ€™s that life gets busyโ€ฆ
Youโ€™re tiredโ€ฆ
And the idea of starting feels overwhelming.

So you wait.

For the โ€œright time.โ€
For more energy.
For things to calm down.

But that time never really comes, does it?

And another 4 weeks pass anyway.

This is your reminderโ€ฆ

The second-best time to start is now.

Thatโ€™s exactly why Iโ€™ve opened a few spaces in our 28-Day Body Transformation Kickstart, starting next week.

๐Ÿ“ Sheffield S8 โ€“ Meadowhead School
๐Ÿ“ Sheffield S10 โ€“ King Edward Lower School

This is designed specifically for women 40+ who want to:

โœ” Lose body fat
โœ” Get stronger (without feeling intimidated)
โœ” Boost energy levels
โœ” Feel better in their clothes again

And noโ€ฆ itโ€™s not just random workouts.

Youโ€™ll be doing:
โœ” Bodyweight strength training
โœ” Resistance band strength training
โœ” Boxercise (great stress relief + calorie burn)

So youโ€™re not just โ€œexercisingโ€โ€ฆ

Youโ€™re actually changing how your body feels and functions.

More energy.
Less out of breath.
Stronger.
More confident.

And for many women, this becomes the turning point.

So hereโ€™s your choice:

Do nothingโ€ฆ
And be in the same place in 4 weeks.

Or start nowโ€ฆ
And feel like a different person.
