Sugar Withdrawal:

Comment by Project Body Smart: We’re talking processed sugars. Sugars naturally found in whole foods don’t have the same levels of addiction because they are consumed in lower doses and along with many other macronutrients.  That being said, the readily available whole foods like fresh and frozen fruits does make it possible to over consume even naturally occurring sugars. So be warned. Moderation is key even with whole fruits and other whole foods containing natural sugars.  A little common sense and education goes a long way.

How to Beat Your Cravings and Give Up for Good

Sugar Withdrawal - Give Up Sugar For Good
SHARES603

Sugar withdrawal is an increasingly common problem as people try to move toward healthier food choices.

In recent times, the world is eating far too much sugar, and this has disastrous health consequences.

Unfortunately, upon trying to give up sugar, many people experience sugar withdrawal symptoms.

This article will explain what these symptoms are and how to beat them.

What is Sugar Withdrawal?

Sugar Withdrawal

Giving up sugar is tough. When you eat something every day and then cut it out, it’s always a challenge. In addition to this, sugar has some unique properties that make it especially addictive:

  • Sugar stimulates dopamine release in a similar way to class-A drugs. Dopamine is a hormonal chemical that affects our feelings and emotions, making us feel good (1, 2).
  • People regularly consuming sugary foods have a delayed satiation response. As a result, they do not feel satisfied when full and seek out more food (3, 4).
  • Animal studies show sugar to be even more addictive than cocaine (5).

As you can see, sugar can be an extremely addictive substance. Therefore, making a choice to give it up isn’t quite as straightforward as we’d like.

The symptoms of sugar withdrawal are both physically and emotionally draining.

Later on in this article, we will go into these symptoms in more detail, but first, let’s take a look at sugar addiction.

In order to understand sugar withdrawal, it’s critical to comprehend why sugar addiction happens and how to control it.

Key Point: Sugar withdrawal refers to the negative effects experienced when trying to give up sugar. Sugar is very addictive, and cutting it out of the diet can be difficult.

Symptoms of Sugar Addiction

If you eat a lot of sugar, one of the first questions you should ask yourself is whether you are addicted.

When does just liking the taste and being “a little greedy” morph into full-blown addiction? Is there a difference? Could you quit sugar right now without difficulty?

The truth is this: our society normalizes sugar consumption. As a result, the majority of people don’t even realize they may have an addiction.

Here are some common signs of sugar addiction:

  • Emotional eating – had a bad day at the office and need a sugar fix?
  • The desire to eat more food, even when you are full.
  • Visiting a bakery and instead of buying one thing, choosing several and eating them all in one sitting.
  • Making excuses to justify eating sugary food (to yourself!)
  • Feeling guilty about what you ate afterward. Often this guilt is because you didn’t want to eat the food but couldn’t resist the urge.
  • Eating sugary food only when alone – hiding it – and making sure there’s no evidence left behind (receipts/packaging).

Does any of this sound like you?

Key Point: There’s a fine line between overdoing it and an addiction: many people don’t realize they might have a sugar addiction.

Craving Sweets and Products Full of Sugar

People suffering from sugar addiction often find themselves craving sweets. As a natural side-effect of this, they seek out and choose more highly processed foods.

In other words, sugar addicts will also be eating lots of refined carbohydrates, vegetable oil, and possibly trans fat.

All of these industrial products are very damaging in their own right (6, 7, 8, 9, 10).

Unfortunately, these foods are what most people are eating every single day.

In view of a recent study into American dietary habits, ultra-processed food contributes 57.9% of all consumed calories. On average, processed food contains 21.1% sugar by weight.

A quick calculation suggests this means 12% of the average diet is pure sugar. When you consider that many people are eating upward of 3000 calories per day, this is pretty scary.

We can also understand how hard it is for the average person to cut sugar from their diet.

If any of this sounds like you, then the next step is to think about cutting sugar out.

Key Point: Sugar addiction is very real and it’s often not recognized. Uncontrollably strong urges to eat sweet food despite not wanting to is a big warning sign.

How to Give Up Sugar

How to Give Up Sugar

In truth, there’s no easy way to give up sugar.

Despite this, knowing how to stop eating sugar gives you the best possible chance to succeed.

Here are some ways to give sugar up:

  • Go through your kitchen and remove any sugar-containing products (and no, you don’t have to finish them first!) If you feel bad about throwing food out, then how about donating it to a food bank?
  • Tell your friends and family about quitting sugar – don’t be shy about it. This honesty provides two benefits – the first is that you can gain support and motivation from the people close to you. Secondly, you don’t have to make excuses for turning down random snacks they might give you.
  • Eat enough food. This one is of particular importance. If you want to lose weight, forget about that for a while and concentrate on beating your sugar addiction. If you are hungry and addicted to sugar, you will fail. Energy-dense, nutritious foods like nuts, avocado, cheese and dark chocolate (85% or above) will help. Eat whatever, whenever, and as much as you want for the first several days because this is the hardest time.
  • Make smart substitutes for the foods you currently eat. Instead of milk chocolate, replace it with dark chocolate. Rather than drinking a big glass of sugary fruit juice, eat a piece of fruit.

Another key point to realize is that dietary fat is not harmful. In fact, the idea that eating fat will cause us to get fat is one of the biggest lies of conventional nutrition.

If this idea seems new to you, then I suggest reading some of the top nutrition books to improve your understanding.

Key Point: Giving up sugar is extremely tough, but it can be done. Remember to include lots of nutritious food and don’t let yourself get hungry while making the transition.

Sugar Withdrawal Symptoms

Sugar Withdrawal Symptoms

What are the symptoms of sugar withdrawal?

Symptoms include extremely intense sugar cravings, headaches, and fatigue. Unfortunately, though, these are just a few of many.

A full list of possible symptoms of sugar withdrawal:

  • Anxiety
  • Depression
  • Dizziness
  • Fatigue and general tiredness
  • Feeling lightheaded
  • Headaches – usually mild but can sometimes be intense
  • Hunger cravings, even if you are full
  • Insomnia and trouble getting to sleep
  • Irritability
  • Moodiness/mood swings
  • Muscular aches and pains
  • Weight loss (finally a positive one!)

Sugar withdrawal headaches and fatigue are two of the most commonly reported symptoms of giving up sugar.

Often, many of these symptoms are simply down to not eating enough food, though. When people cut out sugar, they don’t replace it with healthier options.

As a result, this amplifies sugar cravings and fatigue.

It’s important to realize that these sugar withdrawal symptoms are short-term. It may feel like they will never subside, but they will in due time (usually less than five days).

Key Point: Many people experience unbearable sugar withdrawal symptoms when they try to give up. Don’t panic though as they are only temporary – stay strong and they will pass.

Healthy Lifestyle Choices to Beat Sugar Withdrawal

Healthy Lifestyle Choices Are Important

You can help minimize sugar withdrawal difficulties by adopting healthier lifestyle practices.

  • Try and ensure at least 7 hours sleep per night. Studies show that sleep deprivation alters hormones that regulate appetite. In other words, less sleep may equal more cravings (11, 12, 13).
  • Consider starting an exercise program. In addition to the direct benefits of working out, studies suggest that it also reduces cravings and decreases hunger hormones (14, 15).
  • If you have any stress in your work/family life, then take some time for yourself. Find something you love doing and set some time aside for it each week. The enjoyment factor is important in life – and it’s essential to managing stress. Not surprisingly, stress also impacts food cravings and causes people to overeat (16, 17, 18).

Key Point: Lifestyle factors such as exercise, sleep and stress all play an important role in health. They can also strongly impact food choices. Paying attention to overall health will help you beat sugar withdrawal.

Sugar Withdrawal: Foods to Avoid While You Give Up

Foods to Give Up During Sugar Withdrawal

Not only should you give up sugar, but also starch, grains and other significant sources of carbohydrate should be restricted while you quit.

If you wish to restart these foods after you give up sugar, then you can do so. However, carbohydrate-dense foods spike blood sugar levels, which is known to stimulate hunger and cravings (19, 20).

As a result, we want to keep carbohydrate levels down while you go through sugar withdrawal.

Here is a full list of foods to avoid when you first give up sugar:

  • Added sugar
  • Artificial sweeteners
  • Bagels
  • Biscuits
  • Bread
  • Bread buns
  • Brownies
  • Cakes
  • Candy/Sweets
  • Canned fruit
  • Cereal
  • Chocolate
  • Cookies
  • Corn
  • Crackers
  • Croissant
  • Donuts
  • Dried fruit
  • French Fries/Chips
  • Fruit Jam/Jelly
  • Fruit juice
  • Ice cream
  • Milk
  • Muffins
  • ‘Natural’ sweeteners
  • Oats
  • Pasta
  • Pies
  • Pizza
  • Potatoes
  • Potato chips
  • Pretzels
  • Puddings / Desserts in general
  • Rice
  • Sauces and Condiments such as ketchup, BBQ sauce, etc
  • Tacos
  • Tortillas
  • Wheat in general

Each of these foods will impact blood glucose levels, which may trigger more intense sugar cravings.

In spite of sweeteners not affecting blood sugar, it’s best to avoid them for anyone going through sugar withdrawal.

Key Point: Avoiding all sources of sugar and starchy carbohydrate is the best option to beat sugar withdrawal.

Sugar Substitutes: Why You Should Avoid Them

Sugar Substitutes

Whenever I see a discussion about sugar addiction or quitting sugar, I often see sugar substitute recommendations.

Sugar substitutes come in three sizes, below are a few examples:

Sugars processed from food: agave syrup, high fructose corn syrup, honey, yacon syrup

Artificial Sweeteners: Aspartame, Acesulfame-K, Saccharin, Sucralose

Natural sweeteners: Erythritol, Stevia, Xylitol

However, if we look to the science then maybe it’s best to avoid any sugar substitute during the early stages of sugar withdrawal. You can add them back in once you are over the worst.

Sugar withdrawal is a tough process to go through, and many studies suggest that sweet taste alone is enough to trigger hormonal cravings for sugar.

Let’s take a look at some of the evidence:

  • Sweetness without calories provides only partial activation of food reward systems in the brain, which may cause us to seek more sweet food. Artificial sweeteners encourage sugar craving and sugar dependence, precisely because they are sweet (21).
  • Out of 3682 individuals monitored for 7-8 years, those who drank artificially sweetened drinks had a 47% higher increase in BMI than those who did not (22).
  • A controlled study showed that drinking aspartame-sweetened drinks increased appetite in young men compared to those who didn’t (23).

Most of this research is on artificial sweeteners, but limited data is available on newly popular natural sweeteners at this time.

If you want to beat sugar withdrawal and give up sugar for good, then you don’t want to be craving a sweet taste.

Key Point: Despite being non-caloric and free of sugar, sweeteners may also increase sugar cravings.

Sugar Withdrawal: is it Necessary to Give Up Sugar?

Dangers of Sugar

Often, people make the decision to quit sugar with the best possible intention.

Sadly, when they see the amount of food products that contain sugar, they get overwhelmed.

If they manage to get past this, then the symptoms of sugar withdrawal can often be too much.

Maybe you are even struggling with sugar withdrawal symptoms right now as you are reading this.

Generally speaking, many people know that sugar can cause weight gain and diabetes. The real extent of the damage sugar causes is lesser well known.

With this in mind, let me outline the dangers of sugar consumption.

The Dangers of Sugar

  • Sugar and cancer: Sugar’s impact on inflammatory pathways increases the risk of cancer (24).
  • Sugar and heart disease: those getting 17-21% of calories from sugar have a 38% higher risk of dying from heart disease than people eating less than 8%. This association persists as sugar intake rises; increased sugar intake, higher risk of death from heart disease (25).
  • Sugar and Alzheimer’s: Higher blood glucose levels lead to increased amyloid beta plaque in the brain. This plaque is a major factor in the development of Alzheimer’s disease (26).
  • Sugar and Diabetes: Many large-scale studies suggest sugar consumption is a driver of diabetes independently of obesity (27).
  • Sugar and mortality: Controlled animal studies show human-relevant sugar consumption increases all-cause mortality and reduces lifespan. Further, this remains the case when the diet is highly nutritive except for the sugar content (28).

As you can see from this, losing a few pounds isn’t the only reason to give up sugar.

Going through sugar withdrawal may potentially save your life.

Key Point: Sugar doesn’t only cause weight gain – it is linked to the worst chronic diseases in the world. The more you eat, the higher the risk.

How to Beat Sugar Withdrawal: Some Expert Tips

Ask the Experts

Here are a few expert tips from people in the nutrition world.

Go slowly and, if applicable, involve the whole family. We must involve the children and all eat sugar free, because chronic health conditions don’t happen overnight, they take decades to develop. Start now to reap the benefits later.

Make simple changes to begin with, start slow and learn to make your family favorites by simply removing the sugar and processed carbs. Strive for improvement, not perfection.

Libby, founder of www.ditchthecarbs.com – one of the biggest low-carb websites in the world.

Here Libby from Ditch the Carbs gives some great advice on how to involve the whole family. Additionally, she makes an excellent point: perfection doesn’t always happen straight away. In other words – keep at it!


I like to prevent sugar cravings before they start. For many of my clients, eating enough fat and protein, particularly at breakfast, helps minimize sugar cravings throughout the day.

Lily Nichols, Registered Dietitian and founder of the popular pilatesnutritionist.com

Registered Dietitian Lily Nichols makes a great point here. The best way to deal with sugar withdrawal is to stop cravings before they start – from breakfast onwards.

For anyone who is seeking guidance and support, Lily also offers nutrition consulting services on her site.


What worked for me was to replace sugar with low carb sweeteners like stevia and erythritol. As time went on, I slowly reduced the amount of sweets I consumed and my cravings for sweet foods have diminished. Cutting carbohydrates and increasing fat has also helped me to break away from eating sugar.

Further great advice to follow from Lisa. Increasing healthy sources of fat and cutting carbohydrate does a great deal for satiety. Making sure you eat enough fat will also make getting through the sugar withdrawal phase easier.


My recommendation to beat sugar cravings is to eat healthy food regularly. If you need to snack, then snacking on dark chocolate, fruit and vegetables are a great way to curb those desires for sugar.

Jenny also provides some excellent advice here – if we are craving sugar, then making sure we eat enough is essential. If we are full, then the intensity of cravings reduces. Regarding fruit, a mixture of fresh berries with cream is a great, tasty way to fill up.


The words of Karen Thomson also hold a lot of weight concerning sugar withdrawal, addiction, and the will to give up sugar.

Karen is a self-confessed former sugar addict, and you can read her thoughts in my earlier article on sugar addiction.

Final Thoughts

The motivation to give up sugar is a great start, but quitting for good requires commitment and persistence.

Depending on the person, how much sugar you used to eat, and some other factors, it will be different for everyone.

At times, detoxing from sugar will be very tough – I hope that the advice contained within this article can help you out.

To sum up, please remember these three points:

  • Seek help and support from people close to you in your life.
  • Remember all the benefits you will get if you give up – use them as motivation.

If you do all these things, and you have the true desire, then I’m confident you can beat sugar withdrawal.
