Did you know that the average person in the United States consumes about half a cup of sugar every day? Cutting back on sugar can be tough because it often leads to cravings, and some people even experience symptoms similar to withdrawal. So, what exactly happens to your brain and body when you decide to quit sugar?
Within the first day of cutting out refined sugar, you might start losing some water weight. This happens because your body manages blood sugar levels using the pancreas, which releases two hormones: insulin and glucagon. When your blood sugar is too high, insulin is released, and when it’s too low, glucagon is released. Without sugar, your blood sugar levels drop, prompting the pancreas to release glucagon. This hormone breaks down glycogen, the stored form of sugar in your body, to provide energy. Since glycogen is bound to water, breaking it down results in losing water weight.
On the second day, you might feel tired and crave sugar as your body looks for new energy sources. This process, called gluconeogenesis, involves converting proteins into sugars, while fats are broken down into ketones for energy. This can make you feel tired, give you headaches, and increase your sugar cravings. Although animal studies show that sugar can trigger dopamine release, there’s no solid evidence that sugar is as addictive as drugs like cocaine in humans.
By the third day, you might notice a metallic taste in your mouth and changes in your breath. This happens because breaking down fat into ketones can produce a smell similar to nail polish remover. These changes can last from a few days to a few weeks, especially if you’re avoiding all forms of sugar, including fruits.
Between days five and ten, your taste buds may become more sensitive to sugar. Research shows that people who fast for several days can detect sweet flavors at lower levels. This increased sensitivity occurs because consuming a lot of sugar can dull your taste receptors, making you add more sugar to get the same sweet taste.
After six weeks without sugar, you might notice that your digestion improves, with more regular bowel movements and less bloating and cramping. Conditions like IBS affect many people, and reducing refined sugars can help alleviate symptoms.
After ten weeks of low sugar intake, you may see improvements in your skin, as sugar has been linked to acne. Clinical trials have shown that reducing sugar can lead to fewer acne breakouts.
After a year without added sugar, you might experience better sleep quality. Some studies suggest a link between low sugar intake and reduced insomnia, although the relationship between sugar and sleep is still being explored.
After one to five years of avoiding added sugars, your risk of high blood pressure, heart disease, type 2 diabetes, and obesity may decrease. High sugar intake is associated with various health issues, mainly because of its link to obesity.
It’s interesting to note that nearly 46% of added sugar in our diets comes from soda, and the consumption of sugary drinks has been declining in recent years. If you’re thinking about cutting out sugar, you might wonder if replacing it with artificial sweeteners is a good idea. We have a podcast discussing this topic, which you can check out.

The average American consumes half a cup or more of sugar every day, and surveys suggest that eating less sugar can lead to increased cravings. Some individuals even report experiencing withdrawal-like symptoms. So, what happens to your brain and body when you try to quit sugar?
After 24 hours without refined sugar, you may start to lose water weight. Our bodies regulate blood sugar levels through the pancreas, which releases two hormones: insulin and glucagon. When blood sugar levels are too high, insulin is released, and when they are too low, glucagon is released. In the first 24 hours without sugar, blood sugar levels drop, prompting the pancreas to release glucagon, which breaks down glycogen (the storage form of sugar in our bodies) to provide energy. Glycogen is bound to water, so this breakdown contributes to the initial loss of water weight.
On day two, you might start to feel fatigued and crave sugar as your body seeks new energy sources. This process, known as gluconeogenesis, involves converting proteins into sugars, and fats are broken down into ketones for energy. This can lead to feelings of tiredness, headaches, and sugar cravings. While animal studies have shown that sugar can activate neurochemical pathways related to dopamine release, there is no conclusive evidence that sugar is as addictive as drugs like cocaine in humans.
By day three, you may notice a metallic taste in your mouth and changes in your breath due to the breakdown of fat into ketones, which can produce a smell similar to nail polish remover. This change can last from a few days to a few weeks, especially if you are avoiding all forms of sugar, including fruits.
From days five to ten, your taste buds may become more sensitive to sugar. Research has indicated that individuals who fast for several days can detect sweet flavors at lower thresholds. This increased sensitivity occurs because high sugar consumption can dull taste receptors, leading people to add more sugar to achieve the same sweet flavor.
After six weeks without sugar, you might find that your bowel movements become more regular, with reduced bloating and cramps. Conditions like IBS affect a significant portion of the population, and reducing refined sugars can alleviate symptoms.
After ten weeks of low sugar intake, you may notice improvements in your skin health, as sugar has been linked to acne. Clinical trials have shown that reducing sugar can lead to a decrease in acne lesions.
After one year without added sugar, you may experience improved sleep quality. Some studies have suggested a correlation between low sugar intake and reduced insomnia, although the relationship between sugar and sleep is still being studied.
After one to five years of avoiding added sugars, your risk of high blood pressure, heart disease, type 2 diabetes, and obesity may decrease. High sugar intake is associated with various health issues, primarily due to its link to obesity.
It’s worth noting that nearly 46% of added sugar in our diets comes from soda, and consumption of sugary drinks has declined in recent years. If you’re considering cutting out sugar, you might wonder if replacing it with artificial sweeteners is a viable option. We have a podcast discussing this topic, which you can check out.
