Keto Diet: Effective Strategy To Alleviate Gerd Symptoms?

The ketogenic diet, commonly known as the keto diet, is a popular weight-loss strategy that involves reducing carbohydrate intake and increasing protein and fat consumption. While the keto diet has gained traction for its potential health benefits, there are concerns about its impact on acid reflux or gastroesophageal reflux disease (GERD). Acid reflux occurs when stomach acid flows back into the oesophagus, causing irritation and heartburn. The high-fat content of the keto diet may increase the likelihood of acid reflux by relaxing the lower oesophageal sphincter, allowing stomach acids to back up into the oesophagus. Additionally, certain keto-friendly foods, such as dairy, fried foods, and processed meats, can also contribute to acid reflux symptoms. However, some studies suggest that a very low-carbohydrate diet may improve GERD symptoms, especially in obese individuals. The conflicting evidence highlights the need for further research to fully understand the connection between the keto diet and acid reflux.

A low-carb diet can reduce GERD symptoms

Gastroesophageal reflux disease (GERD) is a common digestive disorder affecting around 30% of North Americans. Symptoms include heartburn, problems swallowing, regurgitation, and a sore throat. While acid-blocking drugs are often used to reduce symptoms, they don't address the underlying causes of GERD.

A GERD-friendly diet typically restricts carbohydrates, at least in the short term. This is because undigested carbohydrates can be a key driver of heartburn. When carbs are not properly broken down, they ferment, producing gas. This leads to increased intra-abdominal pressure (IAP), which can cause GERD symptoms.

A low-carb diet can, therefore, be an effective way to alleviate GERD symptoms. In this diet, 10-15% of calories come from carbs, which equates to 65-100 grams of carbs per day for men and 50-75 grams per day for women. It's important to note that the quality of carbs matters, with cellular carbohydrates found in plant foods being preferable to acellular carbs found in products like flour or sugar.

Non-starchy vegetables are naturally low in carbs and don't need to be counted toward the daily limit. Starchy plants and fruits like berries, tomatoes, plums, and peaches can make up the bulk of your carb intake.

The ketogenic (keto) diet is a more restrictive form of a low-carb diet, limiting carbs to 5-10% of daily calories. While it can be beneficial for those with serious GERD symptoms or other conditions like type 2 diabetes, it may not be suitable for everyone.

It's worth noting that a low-carb diet may not be a long-term solution, as carbohydrates are also important for feeding beneficial gut bacteria. However, reducing carb intake for a limited time can be an effective early step in reducing GERD symptoms and improving gut health, in conjunction with other treatments.

In addition to dietary changes, there are other lifestyle modifications that can help manage GERD. These include staying upright after eating, limiting liquids during meals, and avoiding activities that require bending over or physical exertion right after a meal.

Fatty foods can cause acid reflux

Fatty foods, such as fried foods, full-fat dairy, and fatty meats, can increase the likelihood of acid reflux. This is because fatty foods take longer to digest, delaying the stomach from emptying, which is a known cause of acid reflux. Fatty foods also cause the release of the hormone cholecystokinin (CCK), which relaxes the lower oesophageal sphincter (LES), a valve that prevents acid from travelling up from the stomach into the oesophagus. When this valve relaxes, it fails to prevent the backflow of stomach acid into the oesophagus.

The National Institute of Diabetes and Digestive and Kidney Diseases states that fatty foods lower pressure on the LES and delay stomach emptying, increasing the risk of reflux symptoms. Fatty foods that may cause acid reflux include deep-fried onion rings, fatty meats like bacon and sausage, high-fat creamy salad dressings, and creamy sauces and dips. Saturated fats, such as butter, cream, and cheese, are particularly likely to cause acid reflux.

A 2006 study found that obese individuals with GERD who followed a very low-carbohydrate diet experienced a reduction in symptoms. The keto diet, which involves reducing carbohydrates and increasing protein and fat intake, may therefore help with acid reflux. However, the keto diet may also spell trouble for those with acid reflux, as high-fat foods can cause acid reflux symptoms.

GERD is caused by low stomach acid

Gastroesophageal Reflux Disease (GERD) is a chronic digestive disorder that affects millions worldwide. It occurs when stomach acid flows back into the oesophagus, causing symptoms such as heartburn, regurgitation, chest pain, and difficulty swallowing. While it was previously believed that acid reflux was triggered by excess stomach acid, an emerging perspective suggests that low stomach acid may be the culprit. This condition is known as hypochlorhydria.

The Role of Stomach Acid

Stomach acid, or hydrochloric acid (HCl), plays a crucial role in the digestive system. It aids in the initial digestion of food by creating an acidic environment in the stomach, which helps break down complex carbohydrates, proteins, and fats. Additionally, stomach acid activates digestive enzymes such as pepsin, which is essential for protein digestion. Stomach acid also acts as a defence mechanism against harmful microorganisms that may be present in ingested food or beverages.

Hypochlorhydria

Hypochlorhydria is a condition characterised by low levels of stomach acid. This can be caused by various factors, including aging, chronic stress, certain medical conditions, and nutrient deficiencies. As a result, individuals with hypochlorhydria may experience impaired digestion, nutrient deficiencies, and gastrointestinal discomfort.

The Alternative Hypothesis

The alternative hypothesis challenges the conventional belief that acid reflux is caused by excess stomach acid. Instead, it proposes that insufficient stomach acid may be the underlying issue. When stomach acid levels are too low, the digestive process is compromised, leading to undigested food particles that can put additional stress on the lower oesophageal sphincter (LES). This can cause the abnormal relaxation of the LES and allow stomach contents to flow back into the oesophagus, resulting in acid reflux.

Clinical Observations and Research

Several studies and clinical observations support the alternative hypothesis, suggesting a link between optimising stomach acid levels and improvements in acid reflux symptoms. Interventions aimed at increasing stomach acid production have shown promising results in relieving GERD symptoms in some individuals. Additionally, research has demonstrated an association between low stomach acid conditions, such as hypochlorhydria, and the presence of GERD symptoms.

Challenges and Controversies

While the alternative hypothesis is intriguing, critics argue that the evidence supporting the link between low stomach acid and acid reflux is not yet conclusive. They emphasise the multifactorial nature of GERD, with diet and lifestyle also playing significant roles. Additionally, there are questions about the effectiveness and safety of therapies aimed at boosting stomach acid production. More research is needed to fully understand the complex relationship between stomach acid levels, LES function, and acid reflux.

Acid reflux is a common problem on the keto diet

The keto diet is a popular choice for many people, with its promise of quick weight loss and health benefits. However, one common problem that people may experience on this high-fat, low-carb diet is acid reflux. Acid reflux occurs when stomach acid flows back into the oesophagus, causing irritation, heartburn, and other uncomfortable symptoms. So, why does this happen, and what can be done to prevent it?

The connection between acid reflux and the keto diet

The exact link between acid reflux and the keto diet is not yet fully understood. However, it is believed that the high-fat content of a ketogenic diet may be a contributing factor. High-fat foods can cause the muscles in the lower oesophagus to relax, allowing stomach acids to back up into the oesophagus and cause irritation. Additionally, certain foods commonly consumed on a keto diet, such as dairy, fried foods, and processed meats, can also increase the risk of acid reflux.

Preventing and managing acid reflux on keto

There are several strategies that individuals on the keto diet can employ to reduce their risk of experiencing acid reflux:

• Limit liquids during meals: Drinking too much liquid can dilute digestive enzymes and lead to indigestion and increased gas and air in the intestines, causing bloating and cramping. Instead, try drinking liquids between meals or limiting yourself to a few sips during a meal.
• Eat slowly and carefully: Avoid overeating, especially fatty foods, in one sitting.
• Stay upright after eating: Eating and sitting upright helps keep food and stomach acids in the stomach. Avoid lying down or doing any strenuous activities that require bending over right after a meal, as this can cause stomach contents to be pushed upward into the oesophagus.
• Focus on fibre-rich vegetables: Include plenty of fibre-rich vegetables, such as broccoli and Brussels sprouts, in your diet to help reduce inflammation in the digestive tract.
• Drink plenty of water: Water can help keep stomach acid at bay and aid in digestion.
• Limit trigger foods: Cut down on dairy, processed meats, and fried and fatty foods, as these can be difficult to digest and increase the risk of acid reflux.

By following these guidelines, individuals on the keto diet can help reduce their risk of acid reflux while still enjoying the potential weight loss and health benefits of the diet. However, it is important to note that the keto diet may not be suitable for everyone, especially those with underlying health conditions. It is always advisable to consult with a healthcare professional before starting any new diet.

A cyclic keto diet is less restrictive

The cyclical ketogenic diet (CKD) is a less restrictive form of the standard keto diet. It involves adhering to a standard keto diet for 5-6 days a week, followed by 1-2 days of higher carb consumption. During the standard keto days, fat should deliver approximately 65-90% of your total calorie intake, with proteins making up 10-30% and carbs under 5%. On the higher-carb days, carbs should make up 60-70% of your total calories, with protein at 15-20% and fat at 5-10%.

The CKD is a form of carb cycling, which is popular among athletes as it is believed to enhance exercise performance. The high-carb days refill glycogen stores, helping athletes recover and prepare for the next exertion. The CKD may also be easier to stick to than the standard keto diet as it allows for occasional carb consumption, which can boost morale and make the diet more sustainable in the long run.

However, there is limited research on the CKD, so the benefits are somewhat speculative. It is also important to note that transitioning from a standard to a cyclical keto diet may result in temporary weight gain due to the body storing each gram of carbs in muscle with at least 3 grams of water. Additionally, it may be easy to consume too many calories on refeeding days, counteracting the weight loss benefits of the standard keto diet.

Overall, the cyclical keto diet is a less restrictive option that may offer benefits for exercise performance and diet adherence. However, more research is needed to fully understand its effectiveness and potential drawbacks.
