The ketogenic diet is a low-carbohydrate, high-fat diet that has been reported to help alleviate acid reflux and heartburn. While the relationship between diet and acid reflux is well-recognized, the underlying mechanism is not well understood. However, certain ingested foods can alter gastric motility and contribute to a weak anti-reflux barrier, which is the underlying cause of acid reflux or gastroesophageal reflux disease (GERD). Hiatal hernia, where a part of the stomach pushes up through the diaphragm into the esophagus, is a common factor leading to a weak anti-reflux barrier. While there are mixed experiences with the ketogenic diet for individuals with a hiatal hernia, some report that their gastric distress symptoms disappeared on a low-calorie ketogenic diet.

What You'll Learn
Ketogenic diets are low-carbohydrate diets
A ketogenic diet is a low-carbohydrate, high-fat diet that has been used in medicine for almost 100 years. It was initially used to treat drug-resistant epilepsy, especially in children. The diet causes the body to release ketones into the bloodstream, which can supply energy for the brain. This metabolic state is called ketosis, where the body uses fat for fuel instead of carbohydrates.
Ketogenic diets can cause weight loss and provide numerous health benefits. For example, it has been shown to improve blood sugar control for patients with type 2 diabetes, and it may also have neuroprotective effects. However, it is hard to follow, and it can be heavy on red meat and other fatty, processed, and salty foods. It may also cause side effects, such as a drop in blood pressure and blood sugar levels, which can be dangerous for people with diabetes.
The relationship between diet and GERD is well-recognized, although not well-studied. A study published in 2006 in the journal of Digestive Diseases and Sciences demonstrated that a very low-carbohydrate diet in obese patients with GERD significantly reduced distal oesophageal acid exposure. All patients reported improvements in heartburn, chest pressure, excessive burping, and other GERD-related symptoms. However, the study is too small to draw any major conclusions, and the underlying mechanism of GERD is not limited to lower oesophageal sphincter pressure and relaxation.
While a ketogenic diet may help alleviate GERD symptoms for some people, it is not a cure-all. The underlying cause of GERD is a weak anti-reflux barrier, which can be affected by factors such as a hiatal hernia, poor oesophageal motility, and delayed gastric emptying. Whether you eat fatty foods or simply drink water, acid reflux is likely to happen if you have a weak anti-reflux barrier. Therefore, it is important to consult a doctor before starting any new diet, especially for an extended period, as it may have side effects, and there is limited research on its long-term effects.

GERD is a gastroduodenal motility disorder
GERD, or Gastroesophageal Reflux Disease, is a gastroduodenal motility disorder. It occurs when acid flows backward out of the stomach and into the lower esophagus. Symptoms include a sour or acidic taste in the mouth, heartburn, chest pain, difficulty swallowing, or a hoarse voice. GERD is a multifactorial problem, with underlying causes including a weak anti-reflux barrier, a hiatal hernia, poor esophageal motility, and delayed gastric emptying. The anti-reflux barrier is a complex anatomical and physiological mechanism that prevents gastric content from refluxing back into the esophagus. The weaker the barrier, the higher the frequency and severity of acid reflux episodes.
The relationship between diet and GERD is recognised but not well studied. For instance, spicy food, alcohol, and chocolate exacerbate acid reflux, but the underlying mechanism is not known. A heavy meal rich in fat is more likely to cause heartburn than a light meal of lean meat and fresh vegetables. Obese patients with GERD often suffer from abnormal carbohydrate digestion, absorption, and metabolism, leading to elevated post-prandial blood glucose and insulin levels. A study published in 2006 in the journal of Digestive Diseases and Sciences found that a very low-carbohydrate diet in obese patients with GERD significantly reduced distal esophageal acid exposure. All patients reported improvements in heartburn, chest pressure, excessive burping, and other GERD-related symptoms.
There are several treatment options for GERD, including medication, endoscopy, high-resolution imaging, balloon dilation, minimally invasive surgery, and incisionless GERD surgery. Medication is often used in combination with lifestyle changes to treat GERD symptoms. Doctors may recommend over-the-counter medications to control acid or prescribe H-2-receptor blockers or proton pump inhibitors. Laparoscopic Heller myotomy is a minimally invasive surgical procedure used to treat achalasia, a condition where the lower esophageal sphincter muscle contracts too strongly. Esophageal balloon dilation is a procedure that widens a narrowed portion of the esophagus. Transoral incisionless fundoplication (TIF) is an incisionless GERD surgery that reinforces a weak esophageal sphincter.

Hiatal hernia is a stomach and esophagus issue
A hiatal hernia is a stomach and oesophagus issue. It is caused when the diaphragm weakens, allowing the stomach to push up through the diaphragm and into the oesophagus. This results in symptoms such as a lump in the throat, nausea, and other gastric distress symptoms such as heartburn and stomach pain.
The underlying cause of acid reflux disease or GERD is a weak anti-reflux barrier. This barrier consists of a complex anatomical and physiological mechanism that prevents gastric content from refluxing back into the oesophagus. A hiatal hernia is one of the factors that contribute to a weak anti-reflux barrier, along with poor oesophageal motility and delayed gastric emptying.
The ketogenic diet is a low-carbohydrate method of eating that has been shown to help alleviate heartburn and acid reflux symptoms in some people. The relationship between diet and GERD is well recognised but not well studied. However, it is important to note that the ketogenic diet did not help everyone with GERD, and some people continued to experience symptoms despite maintaining a healthy lifestyle.
For obese patients with GERD, a very low-carbohydrate diet has been shown to significantly reduce distal oesophageal acid exposure and improve symptoms such as heartburn, chest pressure, and excessive burping. This is because obese patients suffer from abnormal carbohydrate digestion, absorption, and metabolism, which can lead to elevated post-prandial blood glucose and insulin levels, as well as dysfunctional gastric emptying.
While the ketogenic diet may help reduce symptoms of a hiatal hernia and GERD for some people, it is important to consult with a healthcare professional before making any significant dietary changes. Additionally, other treatments such as chiropractic adjustments and massage therapy may also be considered to help soothe symptoms.

Acid reflux is caused by a weak anti-reflux barrier
Acid reflux is a common condition, with almost everyone experiencing it from time to time. It occurs when stomach acid rises into the oesophagus, causing heartburn and other symptoms. While diet is not a cause of acid reflux, certain foods can contribute to it. For instance, spicy food, alcohol, and chocolate can exacerbate acid reflux. However, the underlying cause of acid reflux or GERD is a weak anti-reflux barrier.
The anti-reflux barrier is a complex anatomical and physiological mechanism that prevents gastric content from flowing back into the oesophagus. It consists of the lower oesophageal sphincter (LES), the angle of His, the crural diaphragm, and the phrenoesophageal ligament. The LES is composed of tonically contracted circular smooth muscles, with its resting pressure higher than intra-abdominal pressure, preventing reflux of gastric contents. The angle of His acts as a valve, functioning as another antireflux barrier.
A weak anti-reflux barrier results in an increased frequency and severity of acid reflux episodes. Hiatal hernia, poor oesophageal motility, and delayed gastric emptying are factors contributing to a weak anti-reflux barrier. Obese individuals often suffer from abnormal carbohydrate digestion, absorption, and metabolism, leading to elevated post-prandial blood glucose and insulin levels. This can result in disrupted gastric emptying, which is another cause of acid reflux.
While the relationship between diet and GERD is recognised, it is not well studied. A low-carbohydrate diet has been found to reduce heartburn events in obese patients with GERD, suggesting that a ketogenic diet may help alleviate acid reflux symptoms. However, it is important to note that the study had a small sample size, and more research is needed to draw definitive conclusions.

Obese patients suffer from abnormal carbohydrate digestion
Carbohydrates are macronutrients that play a crucial role in providing energy to the human body. They are broken down into glucose during digestion and absorbed into the bloodstream, leading to an increase in blood sugar levels. The body then releases insulin, which directs glucose to cells for energy. Excess glucose is stored in the liver and muscles for future energy needs. Obese individuals may have a reduced ability to effectively break down and process carbohydrates, leading to abnormal carbohydrate digestion.
Research has identified a link between obesity and the AMY1 gene, which codes for the enzyme salivary amylase. Salivary amylase is crucial in initiating starch digestion in the mouth. The number of copies of the AMY1 gene varies significantly between individuals, and those with fewer copies have a higher likelihood of obesity. This suggests that the physical handling of carbohydrate digestion may contribute to obesity.
Furthermore, obese individuals often experience abnormal post-prandial hormone secretion. Post-prandial hormones such as GLP-1 and PYY are secreted by the gastrointestinal tract after eating. These hormones regulate blood glucose and insulin levels. Obese patients exhibit diminished secretion of these hormones, resulting in elevated post-prandial blood glucose and insulin levels, further contributing to abnormal carbohydrate metabolism.
Interestingly, a low-carbohydrate diet has been found to reduce heartburn events in obese patients with GERD. A study showed that obese patients with GERD who consumed less than 20 grams of carbohydrates per day experienced significant improvements in heartburn, chest pressure, and other GERD-related symptoms. This suggests that a low-carbohydrate diet may help alleviate GERD symptoms in obese individuals, potentially due to the reduction in distal oesophageal acid exposure.
