Welcome to 20 No-Sugar Days Diet


20 no sugar days challenge by days to fitness

For 20 days we’ll avoid all food containing added sugar. To read my 20 Days No-Sugar story check here.

2 Simple Rules

1. No added refined sugars (white sugar, corn syrup, brown sugar etc.)

2. No added artificial sweeteners (Truvia, Splenda, NutraSweet, aspartame etc.)

Most processed food contains added sugar, even the ones you don’t suspect like ketchup, granola, flavored yogurt, salad dressing, and potato chips.

How do you identify added sugar in food? Easy… 

Read any food nutrition labels you have at home and before you buy your groceries at the supermarket. That way you’ll know how much sugar is in your food. Food manufacturers also use a lot of different names in an attempt to disguise sugar so make sure you read this article on identifying “hidden” added sugars  “61 different Names For Sugar”.

What about naturally occurring sugars? Are they okay? Yes!

Milk, plain yogurt, fresh vegetables and fruit contain sugar, and that’s totally okay.

Eat fruit: Enjoy the natural sugar found in fruit. Make a fruit smoothie for breakfast. Try a Mango and avocado smoothie (with milk).

Drink Milk or yogurt (I prefer kefir): Enjoy a yogurt smoothie as a healthy snack or a banana smoothie with kefir superfood for breakfast.

Eat vegetables: Prepare a superfood green smoothie with spirulina to add protein to your diet (Spirulina Green Smoothie)


20 days. You’ll be impressed by the results and, after only this short time, you won’t want to go back to eating tons of added sugar like before.

What can I expect once I finish this challenge?

More energy and focus: Sugar makes you feel tired

Flatten your belly: Most added sugar that you eat is converted into fat

Reduce fat, lose weight:  Less sugar means less fat

Reduce your calorie intake: When you eat less sugar, the two hunger hormones start to working properly and you feel fuller after your meals. No more all-day snacking and feeling constantly hungry.

Enjoy the real taste of foods: Sugar often masks the real taste of food. Coffee and tea, for example, taste so much better once you learn to ditch the sugar.

Be discipline, stay strong, and avoid added sugar in all forms. That means soda, sweetened beverages, candies, cookies, most breakfast cereals and processed food.

No Added Sugar Recipes

Low sugar recipes can help you to avoid buying processed and fast food. Cooking your own low-sugar meals means you know exactly what you ear eating and that makes it much easier to keep your sugar intake low.


Kefir (more about kefir here) was an amazing discovery and I love to mix it with fruit.

Fruit smoothies are also an easy and quick way to have fruit in the morning. Combined with kefir, fruit provides a healthy, light start to the day and the natural sugars taste great – all in under five minutes.

Add some no added sugar muesli to your bowl of fruit and kefir for the perfect breakfast, available at amazon.com.

Recipes for Lunch & Dinner

I’ve put together all the sugar free recipes here so I could easily find and share them with you. They are easy, healthy, and of course, have no added sugar.

Check the recipes, make your grocery list, and organize your meals. This will make the 20 No Sugar Days Challenge much easier.


Amazingly, reducing your sugar intake does not have to mean no desserts. You still can have great-tasting sweet treats without the high levels of added sugar. My no added sugar dessert recipes here.

Questions and Answers

One can of 12 fl oz (335 ml) contains 39 grams of sugar. The American Heart Association recommends 6 teaspoons (24 grams) of sugar per day for women and 9 teaspoons (36 grams) per day for men.  One can has way more sugar than you should have in a single day!

How do I avoid added sugar?

Sugar is addictive and you can find it everywhere. Most processed food contains added sugar. 5 tips at “How to Avoid Sugar ?”

The difference between added sugar vs natural occurring sugar?

Unlike added sugars, natural sugars are present in food already. They are also accompanied by vitamins, minerals, fiber, and amino acids. As such they are healthy when consumed in moderation.

Added sugars are, in contrast, not naturally occurring. They are added to food to alter its taste, texture, or simply to make you crave and buy more of it. It’s often included to make foods borderline addictive which helps increase sales and profits for food manufacturing companies. More at my recent article “Added Vs Natural Sugar”

Learn more about the differences at “Added versus naturally occurring sugar whats the difference?

Where can I find no added sugar foods?

There are healthy sugar alternatives to enjoy, fight your sugar cravings and perfect for your 20 No Sugar Days Challenge. You can find some examples at “Looking for No-Sugar foods” article.

How much added sugar should I really be eating?  

The American Heart Association recommends 6 teaspoons (24 grams) of sugar per day for women and 9 teaspoons (36 grams) per day for men.  

Why I should I reduce my added sugar consumption?

The 5 Most import reasons for avoiding added sugars are…

Sugar is fat: Most of the added sugar we drink or eat is converted and stored by the liver as fat. Sugar is considered one of the main reasons for the current obesity epidemic

Diabetes Type 2: Too much sugar makes your pancreas produce a lot of insulin for long periods of time. This can cause insulin resistance. When you have insulin resistance, it gets very hard for your body to reduce high blood sugar levels which can increase the risk of developing type 2 diabetes

The more sugar you eat, the hungrier you feel: Our hunger and satiety hormones (leptin and ghrelin), are responsible for informing the brain that we are full. When we eat too much sugar, they do not work properly and we never feel full. This leads to overeating and weight gain.

Get tired and sleepy: Metabolizing sugar consumes a lot of energy. That’s why you often feel tired after eating a lot of chocolate or candy. Eating less sugar will give you more energy.

Heart diseases: The liver converts excess sugar into fat which raises the cholesterol levels in your blood. High “bad” cholesterol levels are a major risk factor for heart diseases.

These reasons are supported by studies by The American Heart Association, Harvard University, NCBI, and American Diabetes Association. This is a short version of our full article “5 Healthy Reasons to Avoid Sugar” that you can find here.

Why do I see so many different names for sugar?

Today, there are, 61 different names for sugar. This trick is used by food manufacturers to hide added sugars in food. I’ve published the list at “61 different names for added sugar.”.

How to identify sugar on nutrition labels?

Learn how to read and easily identify sugar on any nutrition label. I’ve created an easy guide called “How to Identify Sugar on Nutrition Labels”.

What about cravings? 

During the first 3-5 days, you’ll probably feel the temptation to eat high-sugar foods like chocolate or drink soda. That’s normal because sugar is very addictive and your body has been used to high levels of sugar for a long period.

Drink water, don’t think about it, channel your energy into distracting tasks to help you forget about sugar. Have a piece of fruit for a natural sugar fix. After a couple of days, these cravings will disappear and you’ll be free of your sugar addiction.

What to do if I slip?

What’s done is done. Don’t look back but, instead, look forward. Continue with the challenge; tomorrow is a new day.

What should I do when having lunch or dinner out?

Don’t be afraid to ask the restaurant if there is added sugar in their meals. Most sauces and salad dressings contain added sugar. Grilled and boiled food are usually safe options regarding added sugar.

What about sugar on coffee or tea?

Please, do yourself a favor and stop adding sugar to your coffee or tea. The first time it’ll taste strange, because with no sugar, you really taste the flavor of coffee and tea. After your 3rd coffee/tea, the strange taste goes away and will start enjoying more the natural flavor of different coffees and the differences between types of tea.

Do you have any no sugar added deserts? 

Yes. You can find them here

What about lunch and dinner, do you have any recipes?

Yes, and yes! You can find all my sugar-free recipes here.

What about cereals?

Most cereals contain high levels of added sugar. Check the nutrition facts and find a low sugar or sugar-free cereal. You may need to visit your local health food shop to do this.

Hi, my name is Sarah and I’m so happy that you’re here! I've shared my story here


    • Hello !

      Thanks for your comment. Yes, of course. I do avoid added sugar but I eat, and recommend, to eat fruit. Fruit provides nutrients, vitamins, fibers and natural sugar, very important elements to our body. Have a great day.

        • Hi Andrew,

          Thanks for your comment. I can’t give you an exact number. AlthoughI can promise you, you’ll lose weight. But it all depends how much sugar are you eating today and how much can you stop eating. Give it a try for at least 10 days, no added sugar, only natural occurring sugar like fruit, milk, etc no soda, candies, chocolates, or any processed food. I’m sure you’ll lose weight, get more energy and way more relaxed. Focus on fighting the cravings and I’m sure you’ll love your days without sugar. Hope I’ve helped, have a great day.

  1. Sara! Starting this 20 day challenge tomorrow, I need it… Now just a quick question, when you say 24 grams does that include natural fruit, do you measure the grams in the fruit??? I like bananas a lot but know that they are quite high in sugar. Also, did you cut out white flours (bread, pasta) and change to whole what for this challenge? Thank you so much for getting this information out to us!

    • Hi Kylee,

      Thanks for your comment. Natural occurring sugar (fruit, milk, etc) does not count for the 24 grams. 24 grams are only for added sugar. There are a lot of different opinions here, I love fruit and fruit provides a lot of vitamins, fiber and nutrients very important to your body, and the natural occurring sugar in fruit is not processed the same way as added sugar. All to say, I’ve fruit every day on my breakfast, what I avoid is all kinds of added sugar, which means, avoid processed food, avoid/reduce adding sugar to my coffee/juices/smoothies, no more sodas. White flours would be an extra step. If it’s your first time trying to get rid of sugar addiction, I would start by the ones I’ve mentioned before. Once you’ve done that first step than you can start with other carbs like bread and pasta. Hope I’ve helped. Have a great day.

    Thank you for making this website I was actually curious about it. I am not the slimmest for my age and I hope that with this diet I will become a bit more fit.

  3. Sara before i seen your post i quit sugar & carbs over a week and the pounds just melted.
    11 pounds in just two wks.
    I do eat a very very small portion of whole grain but i donot include carbs in every meal.
    I still eat a balanced meal everyday and even nuts as a snack so i am never hungry and the pounds are just dropping.
    For many many years I would excercise daily for atleast an hour but the weight would come off slowly. Until my doctor told me sugar was my culprit in which i already knew he just confirmed it.
    Once I decided to give it up for good the cravings also went away as well.
    I plan on losing more weight naturally and finally take back my life with healthier choices .

    • Hi Deb,

      Thanks for your comment. I was so surprised when I start reading about sugar, I didn’t had any idea how sugar can really make you fat. That’s why I decided to read, investigate and publish so many articles about the subject. It’s not easy to say no to sugar, but it feels so good to enjoy your life without sugar. Have a great day.
