'I ditched Diet Coke for four weeks – my body and mind totally changed'


One avid Diet Coke fan who had been told for ‘years’ he was drinking too much of the carbonated beverage has described a ‘spectacular’ difference after giving it up for one month.

Wales Online writer Paul Turner says he always defended his Diet Coke habit as it was ‘zero sugar and zero calories’ – and with Paul being a pescatarian, and avoiding tea or coffee, he wasn’t keen to give up his favourite drink.

But he gave it a go for four weeks, and despite some challenges along the way, he noticed huge changes both in his body and in the way he felt mentally too.

On an average day, Paul was going through around five Diet Cokes, with the fridge always stocked full. He decided to stop drinking it during the week – as he still wanted to enjoy an occasional Tia Maria and Diet Coke on the weekends.

Here’s everything that he discovered whilst on his Diet Coke-free journey for four weeks.

Day 1:

Weight: 14st 7

Waist: 104cm

While day one saw no dramatic physical effects from my sudden change in liquid refreshment, and I found drinking water ok, I did crave sweetness a little. But I did have an epiphany of sorts. I realised that my glass of Coke with a meal was not just for liquid refreshment – I was drinking it because my body had got used to, either by design or desire, having a mouthful of something sweet after every bite of savoury. Now, when I ate – there was no sweet to sandwich the savoury – it was a big change and a transformative moment in my understanding of my own body and habits.

Day 2:

I wouldn’t really call it cold turkey – it wasn’t like I was giving up nicotine or something – but if I had any withdrawal symptoms, today was when they kicked in. I was a little tetchy and short-tempered. I also had a headache in the afternoon. Of course, I have no idea if any of these things were related or just coincidence.

Day 3:

I felt like I’d turned a corner today – felt up for the challenge. I was on holiday at the time which no doubt helped.

Day 4:

The big test – I was back at work – how would I cope with no Diet Coke hit when I had to concentrate all day? Whether it was being back in a normal routine, without my routine beverage, I did start to miss it today.

Day 5:

I went for a 55k cycle in beautiful warm weather this morning and how I craved an ice cold Coke with little bubbles forming on the outside of the glass – I could almost taste it, hear the ice cubes clinking together. That furious debate in my head started all over again.

Day 6:

I felt the need for fruit today, not a feeling I’m accustomed to – so I went out and bought some – also not like me. The fruity, juicy, naturally sugary taste of strawberries and grapes helped a little to soothe my coke cravings.

Day 7:

The first weigh in and the scores on the doors are:

Weight: 14st 5.75

Waist: 101cm

Wow! Not a huge difference weight-wise, but I had lost three centimetres off my waist according to my measurements. I know there is a margin for error here and natural body fluctuations, but it seemed like a great start and spurred me on to continue.

Day 8 onwards:

I stopped recording daily changes at this point. I was in a rhythm now and used to my routine. I still missed my Diet Coke, but I wasn’t craving it, and I found other ways to satiate my sweet tooth – with fruit!

One thing I did find was that I was less tired at work. I found I had peaks and troughs before – perhaps the low after the high of the Diet Coke caffeine and fake sugar rush. If I was tired that day, it was smoothed out, rather than up and down, and much more manageable as a result.

End of week 4 weigh in:

Weight: 14st 4.5

Waist: 99.5cm

My weight is back to its normal fluctuations but still 2.5lbs less than when I started. But I have shaved another half a centimetre off my waist.

End of week 5 weigh in:

Weight: 14st 2.5

Waist: 98.5cm

One month later:

Total weight loss: 4.5lbs

Total waist loss: 5.5cm

Conclusions:

As I said, I set out on this journey, part hoping it would make a difference. I wanted a slimmer waist and exercise alone and some dietary changes hadn’t really made much difference. I also felt like I should shave off a little weight – but my waistline was my main motivation.

I also part hoped it would all make not a jot of difference. I love Diet Coke, have always defended it – and if giving it up proved a waste (or waist) of time, then I could go back to drinking it like I had before. But I can’t ignore 5.5cm off my waist in just a handful of weeks – that seems quite spectacular to me. And the weight loss was also not to be sniffed at. Whether it was all down to the Diet Coke ban, or a combination of things – the numbers do not lie.

So, since the end of this experiment, I have stuck to the plan. I have allowed myself a Diet Coke with food on an occasional meal out (if I’m driving), but other than that, I have ditched it pretty much. I do miss it a little – but not hugely. I’m hoping the weight and the waistline will keep shrinking – but I’ll let you know how it goes if I can.
