We are excited to dive into the topic of belly fat and how to lose it through the power of nutrition. It is important to note that belly fat, also known as visceral fat, can be a result of high levels of cortisol in the body. Cortisol is a stress hormone that turns protein into sugar, causing the liver to create new sugar from non-carbohydrate sources such as fat, ketones, and protein. When cortisol levels are high, insulin levels rise as well, leading to weight gain and potentially diabetes. The foods we consume can either help or hinder our efforts to reduce belly fat.
In this article, we will be discussing the top 10 foods that can help a person lose belly fat. These foods work by either lowering insulin, lowering cortisol, or helping with a fatty liver. Let’s get started!
- Eggs – Eggs are an excellent source of protein and virtually no carbohydrates. When protein is low carb, it triggers the opposing hormone to insulin, which is glucagon. Glucagon helps you burn fat, and eggs are also loaded with lecithin, which helps break down fat in the liver. Additionally, eggs contain choline, which is an excellent fat dissolver for the liver.
- Salmon – Salmon is high in omega-3 fatty acids, which can help reduce insulin resistance and cortisol levels. Omega-3 fatty acids can be found in many other types of fish as well.
- Cod Liver or Cod Liver Oil – Cod liver is an excellent source of omega-3 fatty acids, which can help make insulin more sensitive and reduce cortisol. If you don’t like the taste of cod liver, you can try taking cod liver oil capsules.
- Sauerkraut – Sauerkraut can help increase liver function, reduce inflammation, and feed the microbiome in the gut. It is also high in vitamin C, which is essential for the adrenal gland that produces cortisol.
- Cruciferous Vegetables – Vegetables such as kale, broccoli, brussels sprouts, and arugula are high in minerals such as potassium and magnesium. These minerals can help lower stress and cortisol levels and are essential for reducing insulin resistance.
- Hamburger – A high-quality hamburger that is grass-fed and grass-finished can be an excellent source of protein and fat. It is low in carbohydrates and nutrient-dense, making it a great choice for reducing belly fat.
- Avocado – Avocado contains a chemical called avocatin B, which can help make insulin more sensitive and reduce insulin resistance. It is also a great source of healthy fats and is low in carbohydrates.
- Broccoli Sprouts – Broccoli sprouts contain sulforaphane, which can help reduce visceral fat and liver fat. They are also nutrient-dense and an excellent source of vitamins and minerals.
- Asparagus – Asparagus contains a natural chemical called asparagine, which can help detoxify ammonia from the liver. This chemical can also help make insulin more sensitive and reduce insulin resistance.
- Nutritional Yeast – Nutritional yeast is an excellent source of B vitamins, which are essential for reducing stress and cortisol levels. It is also a great source of protein and can be added to salads for an extra boost of flavor.

While the foods mentioned above can help reduce belly fat, it is also important to avoid certain foods that can hinder our efforts. These foods include:
- Sugar – High levels of sugar can cause insulin spikes and lead to weight gain.
- High-Carb Foods – High-carb foods can also cause insulin spikes and lead to weight gain.
- Processed Foods – Processed foods are typically high in sugar and unhealthy fats, making them a poor choice for reducing belly fat.
- Sugary Foods and Beverages: High sugar intake is one of the biggest culprits of belly fat. This is because consuming too much sugar causes a spike in insulin levels, which in turn promotes fat storage, particularly in the abdominal region. Additionally, high sugar intake can lead to insulin resistance, which can further exacerbate the issue. If you’re looking to lose belly fat, it’s important to cut back on sugary foods and drinks like candy, soda, and baked goods.
- Refined Carbohydrates: Refined carbohydrates like white bread, pasta, and pastries can also contribute to belly fat. These foods are high in simple carbohydrates, which can cause a spike in blood sugar levels and insulin. This can lead to increased fat storage, particularly in the abdominal region. If you’re looking to lose belly fat, it’s important to cut back on these foods and opt for healthier, whole grain alternatives instead.
- Processed Foods: Processed foods like chips, crackers, and pre-packaged meals are often high in calories, unhealthy fats, and added sugars. These foods can contribute to weight gain and belly fat. If you’re looking to lose belly fat, it’s important to limit your intake of processed foods and focus on whole, nutrient-dense foods instead.
- Alcohol: While moderate alcohol consumption may have some health benefits, excessive alcohol intake can contribute to belly fat. This is because alcohol is high in calories and can promote fat storage, particularly in the abdominal region. Additionally, excessive alcohol consumption can lead to poor food choices and a lack of physical activity, which can further exacerbate the issue. If you’re looking to lose belly fat, it’s important to limit your alcohol consumption or avoid it altogether.

Now that we’ve discussed the foods to eat and avoid, let’s take a look at some additional lifestyle changes that can help you lose belly fat.
- Exercise: Regular exercise is one of the most effective ways to lose belly fat. Not only does it help to burn calories and increase metabolism, but it can also promote the release of hormones like cortisol and testosterone, which can help to reduce belly fat. Additionally, resistance training can help to build muscle, which can further increase metabolism and help you burn more calories.
- Sleep: Getting adequate sleep is important for overall health and can also help with weight loss and belly fat reduction. Lack of sleep can disrupt hormone levels, particularly cortisol, which can contribute to weight gain and belly fat. Aim to get 7-8 hours of sleep each night to promote weight loss and overall health.
- Stress Reduction: Chronic stress can lead to the release of cortisol, which can promote belly fat. Engaging in stress-reducing activities like meditation, yoga, or deep breathing can help to reduce cortisol levels and promote weight loss.
- Hydration: Staying hydrated is important for overall health and can also help with weight loss and belly fat reduction. Drinking plenty of water can help to flush out toxins, reduce bloating, and promote a feeling of fullness, which can help to reduce calorie intake.
In conclusion, losing belly fat can be a challenging process, but it’s important to remember that it’s possible with the right approach. By incorporating the right foods into your diet, avoiding the wrong foods, and making lifestyle changes like exercise, sleep, stress reduction, and hydration, you can effectively lose belly fat and improve your overall health. Remember, it’s important to be patient and consistent, and to consult with a healthcare professional before making any significant dietary or lifestyle changes.
After 4 weeks of being on keto + IF had my bi-annual check up with naturopathic doc. She was amazed at the affect it had on my triglycerides, cholesterol and inflammation numbers. Glucose and insulin numbers were down too. What I have learned from Dr Berg in 8 weeks is more than the numerous medical doctors I’ve gone to in the past 25 years!
Finally, someone can explain to me why I have high sugars and rarely eat it!! I had my cortisol checked and it was high. Countless doctors could not answer this question…. I gave up my 2 decade low fat diet and immediately lost 25 lbs.
I love eating Sauerkraut as a salad with pieces of parmigiano, boiled egg, walnuts and avocado, some apple cidre vinegar and lots of olive oil on it. Also adding spices such as thyme, rosemary and marjoram.
Nutritional yeast is great on a salad! My family and I have been using it with ACV and EVOO for over 2 years. It’s a great replacement for ranch dressing.
So many of these foods are great for so many aspects of our health. Great information as always!
