How to End Your Carb Cravings on the Keto Diet

Carbohydrates have always been a staple in the modern diet, but they can also be incredibly addictive. This is because of the way they interact with our bodies and our hormones. From a young age, we are exposed to a variety of sugary and carb-rich foods, including baby food, cereal, candy, and processed foods. These foods are designed to be appealing and to keep us coming back for more. The reason for this is that carbohydrates trigger the release of two hormones, dopamine, and serotonin, which are responsible for feelings of pleasure and happiness. Over time, our bodies become increasingly dependent on these hormones and our addiction to carbs grows stronger. This is why cutting down on carbohydrates can be such a challenge, but it is also why it is so important to learn how to do it effectively.

Breaking the Cycle: Understanding the Role of Dopamine and Serotonin in Carbohydrate Cravings

Dopamine and serotonin are two hormones in the brain that play a major role in regulating our mood and pleasure centers. When we eat carbohydrates, particularly sugary and refined carbs, our bodies release these two hormones in high amounts, creating a temporary feeling of pleasure and happiness. Over time, this leads to the development of a strong addiction to carbs, as our brains start to associate eating carbs with feeling good.

Dopamine is a neurotransmitter responsible for producing feelings of pleasure and reward. When we eat carbs, the dopamine receptors in our brains are triggered, resulting in a rush of dopamine that creates a feeling of pleasure. Over time, our brain becomes conditioned to expect this pleasure response when we eat carbs, leading to stronger and stronger cravings for these foods.

Serotonin is another neurotransmitter that affects our mood and feelings of happiness. Like dopamine, consuming carbs leads to a release of serotonin, creating a temporary feeling of happiness and well-being. Over time, this also contributes to the development of a strong addiction to carbs, as our brains start to associate eating these foods with feeling good.

By understanding the role of these hormones in regulating our cravings for carbs, it becomes clear that breaking the addiction to carbs requires more than just willpower and self-control. It requires taking steps to heal the neurotransmitter receptors in our brain, such as through fasting and exercise, and avoiding the environmental triggers that initiate cravings. Additionally, supplementing with vitamin B1 may help to reduce the addiction to carbs by improving the function of neurotransmitters in the brain.

There is hope for those looking to break their carb addiction. Here are four steps you can take to end your carb cravings on the ketogenic diet.

4 Steps to End Your Cravings

1. Begin Fasting

Fasting and entering into a state of ketosis can be highly effective in reducing sugar and carbohydrate cravings.

When the body is in a state of glucose burning, it is fueled by the sugar in carbohydrates. This can lead to a vicious cycle of high insulin levels, low blood sugar, and intense sugar cravings. Fasting and ketosis, on the other hand, promote fat burning, which can help to balance hormones, reduce inflammation, and reduce sugar cravings.

During fasting, the body will enter into ketosis, which is when it starts to burn stored fat for fuel instead of glucose. This shift in energy source helps to reduce insulin levels and increase glucagon, which promotes fat burning and reduced sugar cravings. Additionally, ketosis has been shown to improve the function of neurotransmitter receptors in the brain, which can help to further reduce cravings for sugar and other addictive substances.

Overall, fasting and ketosis are powerful tools for reducing sugar and carbohydrate cravings, promoting fat-burning, and supporting overall health and well-being. By incorporating these strategies into a ketogenic diet, you can help to break the cycle of carbohydrate addiction and take control of your cravings.

2. Exercise

When you engage in exercise, your body burns glucose (carbohydrates) for energy. This can help to reduce the amount of glucose in your system, which can in turn reduce cravings for carbohydrates. Exercise also releases endorphins, which are natural painkillers that can boost feelings of pleasure and happiness. This can help to counteract the effects of the pleasure and happiness hormones that are triggered by carbohydrates, reducing the desire to consume them.

In addition, exercise has been shown to have a positive effect on insulin sensitivity, which is an important factor in regulating carbohydrate cravings. When you have high insulin sensitivity, your body is able to use insulin more effectively, which helps to reduce cravings for carbohydrates. By improving insulin sensitivity through exercise, you can help to reduce the desire for carbohydrates and improve your overall health and well-being.

The benefits of exercise for reducing carbohydrate cravings are further supported by scientific research. Studies have found that regular exercise is associated with reduced cravings for sweets, reduced consumption of high-carbohydrate foods, and improved overall dietary habits. By incorporating exercise into your daily routine, you can help to break the cycle of carbohydrate addiction and achieve greater control over your cravings.

3. Avoid Triggers

The goal of avoiding triggers is to limit exposure to stimuli that may trigger an urge to consume carbohydrates and sweets. This is because when we encounter these stimuli, they activate the release of pleasure hormones such as dopamine and serotonin, which drive us to seek out more of these foods. These triggers are powerful because they are often linked to positive experiences and emotions in our past, making it difficult to resist the cravings they evoke.

By removing these triggers from our environment, we reduce the frequency and intensity of our cravings, making it easier to resist the urge to consume carbs and sweets. This includes removing all sources of carbohydrates and sugars from your home, avoiding restaurants and other places where you may be exposed to tempting foods, and avoiding cookbooks and other resources that showcase sweets.

It is important to note that this process may take time and effort, as habits and cravings can be deeply ingrained. However, by consistently avoiding triggers and building new habits, it becomes easier to break the cycle of carb addiction and maintain a healthier diet.

Overall, avoiding triggers is an effective strategy for reducing carb cravings and breaking the cycle of addiction. By taking control of your environment and limiting exposure to trigger foods, you can take the first step towards a healthier diet and improved well-being.

4. B Vitamins

Consuming B vitamins, specifically, B1 can help curb carb cravings by providing support to the nervous system and helping to regulate metabolism. B1, also known as thiamine, is involved in the conversion of carbohydrates into energy, which can help to regulate cravings for sugary or carb-rich foods. Additionally, B1 helps to maintain healthy neurotransmitter levels, which are responsible for regulating mood and appetite. Studies have shown that a deficiency in B1 can lead to decreased energy levels and increased food cravings, making B1 an important nutrient for those looking to overcome their carb addiction. By incorporating foods high in B1, such as eggs, nuts, and meat, into your diet, you can help support your nervous system and reduce your cravings for sugary or carb-rich foods.

Foods high in Vitamin B1 (Thiamine) on a ketogenic diet:

  1. Pork: Pork is an excellent source of thiamine and other B vitamins. A 3-ounce serving of pork contains approximately 0.5 milligrams of thiamine.
  2. Nuts and Seeds: Nuts and seeds, such as almonds, sunflower seeds, and pumpkin seeds
  3. Shellfish: Oysters, clams, and mussels are all good sources of thiamine.
  4. Fish: Fish such as salmon, cod, and halibut
  5. Leafy Greens: Leafy greens including kale and spinach
  6. Eggs

It is important to note that thiamine is a water-soluble vitamin and it is possible to overdose on it if large amounts are consumed. It is best to consult with a healthcare professional before taking any supplements.


In conclusion, breaking a carb addiction can be challenging but with the right strategies in place, it can be done. Fasting and exercising are two key ways to reduce carb cravings and get your body into a fat-burning state of ketosis. Avoiding triggers such as sugar, carbohydrates, and certain environments that trigger cravings is also important. Lastly, incorporating B vitamins, particularly B1, into your diet can help reduce the addictive properties of carbohydrates. By following these tips, you can effectively cut your carbohydrate cravings and achieve a healthier, more balanced diet. Remember to be patient and persistent, and to always listen to your body. With the right mindset and approach, you can successfully break your carb addiction and achieve your health and wellness goals.
