With summer cocktails and al fresco dinner parties behind us, it's safe to assume that nutrition over the last few months hasn’t been perfect. One of the biggest complaints that I head after summer is that people are a little jacked up on sugar - whether it be from holiday desserts, those extra iced creams on hot summer days or too much wine. Unfortunately it doesn't take much to throw your blood sugar off balance - even 6 weeks of indulgence can take quite a long time to rebound from. But there’s no point in dwelling (or worse - continuing bad habits out of guilt or anxiety).

It’s time take action and be bold. Enter the 30 day no-sugar challenge.


30 days without sugar is the perfect time to actually feel the benefits, but not too long that it feels like an impossible task. People always gush about the wonderful effects of giving up sugar, and that's because they’re pretty much all true – better skin, concentration, mood, energy, weight loss, more motivation… you name it, and it’s waiting for you on the other side. BUT, what a lot of people don’t talk about are the strange, uncomfortable and potentially sabotaging effects of sugar withdrawal that you need to get through first. By acknowledging them it’s actually far easier to cope with them, so here goes.

The first few days….

These are pretty easy actually. We generally store enough glycogen in our muscles & liver that if sugar isn’t readily available, we just tap into these reserves. If you have loads of sugar, you’ll still have cravings for the post lunch chocolate square (bar), however nothing too dramatic that a little dedication can’t override.

"This is normal and means it's working. Be strong!"

Days 4-8

This is when it could get a little spicy and is when you should expect the main bulk of discomfort. Headaches, mood swings (think angry one minute, crying the next), foggy head, insomnia, body aches, cravings that occupy your mind for hours at a time, agitation….I'm not going to lie - it’s all possible, and you need to be prepared for this. But here’s the important part – this is normal and means it's working. Be Strong! What’s important here is how you set yourself up to beat this phase.

  • Exercise. Cardio will give your mood a great boost, yoga can calm you down, anything really (even a long walk). Make sure you exercise, hydrate, and refuel well during these days.
  • Remember to still eat carbs (yes you can!). Just make sure they’re healthy and paired with some protein. Brown rice, lentils/beans, oats and if you’re really needing a sweet boost use sweet potato and squash to help get you through.
  • Drink water, lemon & cayenne. This will help with your headaches, energy and concentration.
  • Reduce coffee – this is the exact opposite of what you’ll want to do, but if you can grab a green tea instead it’ll be far easier to get through this phase. Keep coffee to one or two per day.
  • Consider supplements. Chromium GTF helps your body deal with blood sugar imbalances and is helpful for cravings. B Complex is another must for any sugar baby looking to make a change.

Days 9-15

Depending on your normal sugar intake, this is when you’ll get a surge of the good stuff. You’ll start to sleep better, energy improves, concentration will get a boost and your skin will have an unusual glow. You’ve definitely made it through the hardest part!

Days 16-18 (ish!)

Ok, you’re through the hard part but usually you have a little rebound effect in week 3 – it’s nowhere near as strong as the first low, but you can get a little grumpy and cravings can come back a bit. This is less likely to happen if you’re still on top of your nutrition, so do a little check in and make sure you’re still getting those fibre rich carbs, good protein and fat.

"A better use of your time and energy would be to focus on what changes you are going to commit to keeping."

Day 19 onwards

Once you’ve made it to hear it’s usually smooth sailing…. Enjoy the rest of the month and feel proud of your strength, discipline and new sense of balance!

Day 30

You’ve made it! Two very important things need to happen now.

Take some time to actually feel proud and acknowledge what you have done. Be aware of the positive effects you’ve seen, and take note of the hard times too so that you can cultivate a stronger awareness of what sugar actually does to your body. If you’ve lost a lot of weight, it means you were eating way too much sugar. If you feel any dramatic shift towards something more positive, you were eating too much sugar.

Most people get to the end of the challenge and spend hours or even days obsessing about what their first treat will be once they’re free. But, a better use of your time and energy would be to focus on what changes you are going to commit to keeping. Write them down and keep yourself accountable. You don’t need to be as strict, but it’s important to set yourself some guidelines. Then, enjoy your first treat within those guidelines.


Not all sugar is created equal, and eating an apple should by no means be synonymous with eating a bowl of ice cream. Yes fruit has sugar, and a lot of it is – gasp – fructose, but fruit also has some of the best profiles of vitamins, minerals, antioxidants, fibre and phytonutrients. The hype around fruit has gone a little crazy to be honest. True - 500g of grapes is probably not the best choice. False - fruit should be avoided full stop.

I’ve prioritised cutting out white and refined flours as a part of this plan as their effects can be just as detrimental on blood sugar fluctuations. I’ve also put skimmed milk on the list, as it’s high in sugar and better to swap to semi skimmed if you’re a milk drinker for the duration of the challenge. This plan has 3 levels, depending on how you want to play it.

Level one is your intro level, and is for anyone who wants to make a change but isn’t up for a full a banishment. This is good for people who are quite sugar heavy but have never really tried a plan before so still allows a fair amount of leeway on fruits.

Level two is starting to get more serious, and is a good challenge for anyone wanting to take their health to the next level. Great for people who eat sugar multiple times per week and probably rely on foods with hidden sugar quite a lot.

Level three is the full monty, and is good for people who want to make a big change, lose weight and see the effects of a full banishment.


What to avoid at all levels:

  • All added granular forms of sugar – think castor sugar, brown, muscavado, coconut sugar etc.
  • All liquid or chemical forms of sugar – think honey, agave, maple syrup, corn syrup, molasses, HFCS, fructose, dextrose, sucrose
  • White/refined flours and all products derived from these
  • All candy, chocolate, sweets, desserts that have any of the above in them
  • Most processed food has some form of sugar in it, so is best to avoid
  • Dried fruit, except fig & date (small portions, only within foods like smoothie or salads)


  • Limit to 2 servings of fruit per day, avoid mango,
  • Avoid skimmed milk


  • Limit to 1 serving of fruit per day
  • Avoid corn
  • Avoid all alcohol except white spirits
  • Avoid all skimmed/low fat/fat free dairy


  • Make sure you still eat carbs. This is not a keto diet! Healthy carbs & fruit are full of nutrition and will help balance blood sugar, regulate digestion & bowel and are great for energy
  • Plan your meals. This doesn’t mean a massive amount of meal prep, but if you’re going to drastically change how you eat you’ll need to set yourself up with ideas and go to lunch spots that will ensure you can be successful.
  • Do it with a friend, it’ll be easier, more motivating and you’ll have someone who will understand when you’re a tad on the moody side on day 3.

There you have it. 30 days sans sugary indulgences….looks like you’ll have to get your sweetness from loved ones instead.
