The benefits of a sugar detox and 7 tips for how to do one effectively, according to dietitians (2024)

• Sugar detoxes are when you cut added sugar for a period of time, either 7, 21, or 30 days.
• To detox from sugar, snack on fruit, eat more protein, and stay hydrated.
• Sugar detoxes can help reduce sugar cravings, aid in weight loss, and improve oral health.

The average American consumes about 20 teaspoons of added sugar per day — a far cry from the recommended amount of six for women and nine for men. As an antidote to excessive sugar consumption, sugar detoxes have grown in popularity.

To be clear, not all sugar is bad. In fact, it occurs naturally in many types of vegetables, fruits, grains, and dairy. But, health problems arise when most of our sugar comes from added sugars, like those in cookies, cakes, bread, plant-based milk, condiments, and more.

So from that perspective, a sugar detox could help you reduce your added sugar intake and in turn embrace a more nutrient-dense diet. Here's what you need to know before trying a sugar detox.

What is a sugar detox?

A sugar detox is when you abstain from eating sugar, specifically added sugar, for at least a week and up to a month in order to reduce sugar intake, curb sugar cravings, and improve overall health.

There are no hard or fast rules when it comes to sugar detoxes, but your focus should be on cutting out added sugars from your diet: that means paying attention to nutritional facts and avoiding sugary sodas, most desserts, processed foods, and even some condiments like ketchup, which can include four grams of sugar per tablespoon.

"There's now lots of emerging research that too much sugar can lead to heart disease and cancer and inflammation," says Lisa Young, RDN, an adjunct professor in the Department of Nutrition and Food Studies at New York University. "So while you might not see the results of cutting out added sugar tomorrow, over time, it's a very big positive for your health."

In fact, a 2017 study estimated if Americans cut their added sugar intake by 20% for 20 years, about 20 fewer people per 100,000 would develop type 2 diabetes, and 10 fewer per 100,000 would develop heart disease. These effects increased the more added sugar was cut.

You might think of detoxes as a short-term mission, but the goal of a sugar detox is to help you re-assess your relationship to sugar in the long term. For some, that means cutting added sugar out of their diets indefinitely, and for others, it may mean re-introducing it in small amounts post-detox. Over time, reducing your added sugar intake can lead to multiple health benefits.

Additionally, your sweet tooth could be impacting your heart: A 2014 study found people who consumed between 17% to 21% of their total daily calories from added sugar had a 38% greater risk of dying from heart disease than people who ate less added sugar —about 8% of their total calories.

Understanding sugar withdrawal

However, cutting out sugar is harder than it seems. Many people begin to feel sugar cravings and withdrawal symptoms a few days into a detox — similar to the craving and withdrawal cycles seen in those quitting nicotine.

"Sugar is a substance that has been shown to release dopamine and opioids in the brain, both of which have addictive potential," says Ilene Ruhoy, MD, a board-certified neurologist and the founder of Center for Healing Neurology.

Receptors in the brain are rewired to compensate for the release of these extra neurotransmitters. Therefore, it's possible when you reduce your sugar intake, your brain craves the extra opioids and dopamine, resulting in withdrawal symptoms.

Symptoms of sugar withdrawal can include:

• Headaches
• Dizziness
• Irritability

Sugar withdrawal symptoms can last between a few days to a week, but there are steps you can take to mitigate them.

7 tips to detox from sugar

Adding certain foods to your diet can help curb sugar cravings and make saying goodbye to added sugars less painful. Here are some tips to combat sugar cravings:

1. Eat breakfast

Eating breakfast with proteins, complex carbohydrates, fiber-rich foods, and healthy fats can keep blood sugar balanced and prevent sugar cravings throughout the day.

2. Start small

If quitting cold turkey is too difficult, gradually reduce added sugar intake before cutting it out entirely. "There's nothing wrong with having a couple of teaspoons of added sugar a day if you stop there," Young says.

3. Eat more healthy fats

Eating healthy fats like those in nuts and fatty fish can help reduce cravings for sugary foods. Try adding some natural (read: no added sugar) nut butter into your diet, or adding a serving of avocado to your lunch.

4. Add protein

Adding extra protein keeps you full and subsequently reduces food cravings. A small 2017 study of people with type two diabetes found a low carbohydrate, high fiber, fat, and protein diet increased feelings of fullness and reduced sugar cravings.

5. Snack on fruit

Embracing natural sugars found in fruits like watermelon, berries, and bananas can help satisfy your sweet tooth. "Opt for foods like fruit that will give you sweetness with fiber to keep your blood sugar steady," says Young.

6. Swap your drinks

Fruit drinks and other packaged beverages can be a sneaky source of added sugar. Replace sodas and lemonade with club soda, unsweetened tea, or just plain water.

7. Stay hydrated

Dehydration can exacerbate sugar cravings, so be sure to drink 3.7 liters of water per day for men, or 2.7 liters for women.

Insider's takeaway

A little bit of sugar isn't a bad thing — but if you find yourself feeling dependent on sugary foods, a sugar detox could help you address your cravings and embrace healthier eating habits.

If you do decide to do a detox, be sure to up your intake of protein, healthy fats, fruit, and fiber and drink plenty of water to keep withdrawal symptoms like headaches and irritability under control.
