Fiona O'Donnell MSc Nutritionist Empowering change for a healthier, fitter you. Nutritionist and lifestyle coach. Founder of Feedback is more than welcome and is very much appreciated.

I built this page initially to chronicle my journey from marathon running to competing in figure competition. I love training and I also love eating - so dieting is a big challenge for me. For this reason, I try to develop new recipes which are gluten free, sugar free, low carb (for the most part) and highly nutritious. I am open to learning as much as I can whilst on this journey. Following completion of my MSc in Exercise & Nutrition Science, I am now working through a post grad in Applied Nutrition with the CISSN.

Kiwis & Sleep.

Another fad? Or does the science support it?

The research is pretty limited - but here’s the thing ….

Kiwis are good for you.
They are a great source of fibre & vitamin C (with or without the skin).

They contribute to gut health & are a precursor to serotonin production in the gut which supports vagal and muscle tone in the gut (peristalsis and gut motility).

While they don’t have the direct effect that we are hearing about on social media - they do support better sleep through a number of indirect mechanisms.

In this age of UPF fearmongering - I am far more supportive of research that translates into encouraging people to add whole foods to their diets.

It’s simple.
It’s an easy step.
It’s cost neutral (kiwis can be purchased cheaply) compared to something like a punnet of blackberries (€4 for 10 😬 in a local supermarket)

And there is no shame, guilt, moral higher ground or superiority in the messaging.

Any thoughts?

I’m asking the question because what I’m seeing is the chronic and systematic exploitation of women’s insecurities about their bodies.

“Oh….. you don’t like those lumps and bumps?…. I can make those smaller….. here’s your 1400 calorie diet - now go starve and come back to me when you’re in a pit of guilt, shame and failure and I’ll make it worse for you”

Look - I get it….

Thousands of you feel uncomfortable in your bodies.

Whether it’s because your clothes were made to fit someone that stepped off the catwalk in Milan or because you’ve put up/lost a few kilos.

Maybe life has gotten busy and suddenly your work pants don’t fit.

Maybe you don’t feel sexy anymore and you prefer to get changed with the light off.

I really do understand!

Perpetuating the narrative that hard restriction is the way forward, really does just bring you back into the cycle where you lose it, gain it back, lose it again, gain back a little more…..

And what’s the outcome?
At a time when your body prioritises bone development (for women up to age 35), you’re withholding nourishment in favour of being thin.

And it’s not your fault.
I’m not judging.
It’s what we’ve been taught is RIGHT.

Chronic low energy availability contributes to increased bone resorption and reduced bone formation.

Hormonal changes (reduced oestrogen) contribute to lower bone mineral density.

Inadequate intake of calcium, protein, vitamin D and other vitamins and minerals are common in energy restricted diets.

If you are going to engage in a weight loss diet - quality matters!

Duration matters!

Understanding where you are in terms of energy intake as a first step can allow you to create a small but effective deficit without compromising your physical health.

I’ve been watching the 2016 trend with interest…

Seeing how life in 2016 has influenced where people are now.

My life in 2016 was so full.
I had started peritoneal dialysis for the first time -

AND I was in the gym four days a week, riding horses most days, swimming, biking running….

The last decade has been so full.
And for a moment, I felt sad.

I felt like I had lost something, as though my life was a little less full right now…

Isn’t it funny these thoughts that pop up - and they are completely inaccurate.

The adventures I’ve had over the last decade have been epic…. And I’m still having them.

I’m in a phase of hard growth…. And that always takes energy.

Onwards.

What’s your yoghurt choice?

Yes, lots of them say ‘protein yoghurt’ and all that….

And many of them have amounts varying from 5g/100ml to 20g/100ml ….

But let’s look at what we actually need to know.

Why do you want a yoghurt?

Is it a pre training snack just to fill your tummy?

Or are you struggling to get enough protein in your day and you are using dairy to bump those bottom lines?

Do you want something tasty for a mid afternoon snack?

Or is a yoghurt part of your breakfast meal?

I remember when ‘muller lights’ were a thing (around the same time as Marlboro lights for me 😫)

They were the wateriest, blandest yoghurts I had ever tasted and I usually ended up having two of them!

I hadn’t really put any mass in how satisfied I felt by my choices.

Now, satisfaction and nourishment are my two deciders when it comes to food choices!

If I made choices based on labels all the time, I’d be pretty miserable - especially as I’m on a pretty strict renal diet!

So…. Here’s your reminder today to eat what works for you….

And where you can, get in your fruit and veg 😀

Pyjama Sundays…

Here’s hoping this is the last of the forced rest Sundays this month and I get to do a bit of training eventually!

At least Alfie is in on the joke!
