I was invited on to Kate Thompson-Duwe ‘s podcast to talk all things fasting with her.

I’ve extracted a section speaking to my favourite analogy when it comes to the different fasting lengths, as most fasting advice treats duration as the only thing that matters… Longer equals better, harder equals more effective. I don't buy that, and I said as much and more on Kate's podcast, The Joy Movement.

The goal is not to grab the biggest tool straight away. It's knowing which level your body actually needs right now, and how to then work with it.

This is the sequence and foods to prioritise/avoid that I use with clients coming off supervised extended or prolonged fasts, adjusted individually for the length of fast and existing conditions.

Not a universal rule, but the principles, slow and sequenced, hold for almost everyone.
Save this for your next fast.

Last week I had ch*****ne at a friend's birthday, ate late, and finished with a sugary pudding. I slept badly and woke up feeling heavy and slow.

By the following evening I felt like myself again.

That quick recovery has little to do with willpower. It comes from the foundation I keep the rest of the time: satiating meals through the week, protected sleep, and a regular fast that gives my liver and gut the space to reset. Alcohol and late sugar both disrupt sleep and blood sugar overnight. A body with a solid baseline clears that quickly. A body without one can carry it for days until it becomes their new normal.

I've written about how I live on an 80/20 principal, what happens in the body after a night like that, and how I use fasting to get back to baseline without treating it as a punishment.

This is the piece most fasting advice skips entirely, especially inside chronic illness spaces, because it was written without a female cycle, perimenopause, or a chronic diagnosis in mind at all.

Save this and check back against it or DM me before you try a new protocol.

Most autoimmune and hormonal protocols are still built on male research.

That’s not a small gap.

Restriction, stress and recovery don’t behave the same way in a female body, and much of the clinical research chronic-illness protocols are built on was conducted on men.

Push through fasting, training or extended stress the way that research assumes a male body will respond, and something eventually breaks, usually your hormones first, especially if you’re already managing an autoimmune or inflammatory condition.

Your cycle, your hormonal stage and your specific diagnosis aren’t details layered on top of a protocol. They’re what the protocol has to be built around from the start.

Follow for the version of this built for your actual body, not the research gap.

None of this is a diet philosophy.

It's the filter I use with every client, chronic condition or not, and once it's a habit, it takes about three seconds.

Save this for the next time you're standing in a supermarket aisle overthinking a label, or wondering if a flare was something you ate.

The system doesn't profit from you leaving it. Mine only works if you do.

If you've been "managed" for years with no end point in sight, that's not treatment, that's retention.

Turns out unstructured time is uncomfortable when you've spent years being the one who runs the household's schedule. It took a few days on our month long holiday before we actually settled into doing nothing, and stopped treating it like a problem to solve.

The school term and new schools for my kids started last week and the mental list came back almost immediately, which told me something... The issue was never really the holiday. It was that I don't really give myself permission to stop the rest of the year, and neither do most of the women I work with.

There's a physiological reason this sits harder on women specifically. Under stress, the female nervous system tends toward what researchers call a tend-and-befriend response rather than the fight-or-flight pattern most stress advice is built around, meaning the stress response itself often shows up as doing more for other people, not less. Female stress physiology also involves a stronger release of corticotrophin-releasing factor, the hormone that switches the stress response on, and fewer of the receptors that switch it back off. Add a mental load that UN Women data puts at over 40% of global GDP if it were ever paid for, and "just rest more" stops being simple advice.

Most of the people I work with don't need convincing that rest matters, they need someone to tell them they're allowed to take it before their body makes the decision for them.
