Keto For Bariatric Patients: Does It Work?

The ketogenic diet, or keto, is a popular weight loss strategy that involves eating a lot of fat and very few carbohydrates. This diet puts the body into a state of ketosis, where it burns fat for energy instead of glucose. While keto can be effective for weight loss, it may not be the best choice for bariatric patients.

Bariatric patients need a diet that is low in carbs and fat but high in protein. A traditional keto diet could be problematic for those with altered stomachs. A modified version of keto that excludes foods like cream cheese, cheddar cheese, bacon, and butter may be a better option for bariatric patients. This modified keto diet focuses on seafood, meats, poultry, low-carb vegetables, cheese in moderation, avocados, eggs, berries, and unsweetened coffee and tea.

While keto can be effective for weight loss, it is not recommended as a long-term approach for bariatric patients. Bariatric patients should always prioritise a high-protein, low-carb, and moderate-fat diet.

The keto diet is not recommended for bariatric patients long-term

• The keto diet is high in fat and low in carbs, which can be problematic for bariatric patients with altered stomachs. Bariatric patients need a diet that is low in carbs and fat but high in protein.
• The keto diet can lead to weight regain if stopped. Bariatric patients who have worked hard to lose weight may find themselves back at square one if they stop following the keto diet.
• The keto diet often includes unhealthy foods, such as saturated and trans fats, which can be dangerous for long-term health. These fats can lead to heart and kidney disease and insulin resistance, which can result in diabetes.
• The keto diet leaves out fruits and vegetables, which are essential sources of vitamins, minerals, and other compounds that promote human health.
• There are concerns about the long-term safety and efficacy of the keto diet. Some studies have found long-term adverse health effects, including kidney stones, hepatic steatosis, and nutrient deficiencies.
• The keto diet can be difficult to follow and may not be sustainable for bariatric patients in the long term. It requires strict tracking of macronutrients and can be challenging to get the right balance of nutrients.
• The keto diet may not be effective for weight loss in bariatric patients. Calorie restriction has been shown to be one of the best methods for weight loss, and the keto diet does not necessarily restrict calories.
• The keto diet can cause the "keto flu," which includes symptoms such as brain fog, headaches, dizziness, fatigue, nausea, insomnia, constipation, trouble exercising, and vomiting. These symptoms can last from a few days to a few weeks and can be difficult to tolerate for bariatric patients.
• The keto diet may not be safe for bariatric patients with certain health conditions. For example, those with micronutrient deficiencies may be at risk of worsening their condition on the keto diet.
• The keto diet may not provide adequate nutrition for bariatric patients. The diet's focus on fat and protein may not provide enough carbohydrates, which are a crucial source of energy for the body.

In summary, while the keto diet may be tempting for bariatric patients looking for a quick fix, it is not a recommended long-term solution. A high-protein, low-carb, and moderate-fat diet is generally a safer and more effective approach for bariatric patients to lose weight and improve their health.

Bariatric patients should eat a high-protein, low-carb, moderate-fat diet

Bariatric Patients: A High-Protein, Low-Carb, Moderate-Fat Diet

Bariatric patients are advised to follow a specific diet plan to ensure optimal health and weight loss results. This typically involves a high-protein, low-carbohydrate, and moderate-fat approach, which may include elements of the popular ketogenic (keto) diet. However, it is important to note that the keto diet is not always suitable for bariatric patients and should be approached with caution.

Phases of Bariatric Dieting

Post-bariatric surgery, patients are guided through different diet phases by their bariatric surgeon. The initial phase typically involves a clear liquid diet, gradually progressing to pureed foods, soft foods, and eventually solid foods. This process helps patients adjust to their new digestive system and promotes weight loss.

The Ketogenic Diet

The ketogenic diet, or keto, is a popular weight-loss approach that involves significantly reducing carbohydrate intake and increasing fat consumption, with adequate protein intake. This dietary shift causes the body to enter a state of ketosis, where it burns fat for energy instead of carbohydrates. While keto can be effective for weight loss in certain instances, it may not be suitable for everyone, especially bariatric patients.

Bariatric Keto Considerations

For bariatric patients considering keto, it is essential to consult a healthcare professional first. Some studies suggest that keto can be beneficial for pre-operative weight loss in bariatric patients, leading to a reduced surgical risk. However, other studies indicate that keto may increase oxidative stress, potentially impacting surgical outcomes negatively. Therefore, it is crucial to assess the benefits and risks for each individual.

Bariatric-Friendly Keto Foods

When adopting a keto diet, bariatric patients should be mindful of their food choices. While high-fat foods like cheese, bacon, and cream cheese are typical keto staples, they may not be suitable for bariatric patients due to their altered digestive systems. Instead, they should focus on:

• Seafood, meats, and poultry: These protein-rich foods contain minimal carbohydrates.
• Low-carb vegetables: Cauliflower, zucchini, and spaghetti squash are great substitutes for higher-carb options.
• Low-fat cheese: Opt for low-fat varieties and use cheese as a garnish rather than a main ingredient.
• Avocados: Avocado halves provide healthy fats and nutrients while being low in net carbs.
• Eggs: Eggs are versatile, protein-rich, and contain minimal carbohydrates.
• Berries: Most fruits are high in carbs, but berries are an exception, offering low-carb, high-fiber options.
• Unsweetened coffee and tea: These beverages contain zero carbs and can boost metabolism and alertness.

Ketosis and Bariatric Surgery

Ketosis, a hallmark of keto diets, may be challenging to achieve for bariatric patients due to their altered digestive systems. Instead of focusing on ketosis, bariatric patients should prioritize a consistent, balanced diet that meets their nutritional needs and promotes sustainable weight loss.

In conclusion, while bariatric patients may benefit from a high-protein, low-carb, moderate-fat diet, they should approach the keto diet with caution and under professional guidance. A modified version of keto, tailored to their specific needs, may be a more suitable and sustainable approach to weight loss and improved health.

The keto diet can be altered to be more bariatric-friendly

The ketogenic (keto) diet is a diet that involves eating lots of fat and very few carbohydrates. By doing so, the body enters a state of ketosis, where it burns fat for energy instead of glucose (carbs). This can lead to weight loss and improved health. However, this diet may not be suitable for bariatric patients as it is high in fat and low in carbs, which could be problematic for those with altered stomachs.

To make the keto diet more bariatric-friendly, it is recommended to focus on a diet that is low in carbs and fat but high in protein. This modified keto diet excludes foods such as cream cheese, cheddar cheese, bacon, and butter. Instead, it includes seafood, meats, poultry, low-carb vegetables, cheese in moderation, avocados, eggs, berries, and unsweetened coffee and tea.

For example, cauliflower can be used as a substitute for rice or mashed potatoes, and zucchini can be turned into "zoodles". One ounce of Parmesan cheese provides 1 gram of carbs, 10 grams of protein, and 35% of the daily requirement for calcium, which is essential for bone health after bariatric surgery. Eggs are also a great option as they contain less than 1 gram of carbs and 7 grams of protein.

It is important to note that post-bariatric patients might not respond to the keto diet in the same way as others. Therefore, it is crucial to focus on a well-balanced, protein-rich diet and stay consistent.

The keto diet can lead to rapid weight loss in the first few weeks

The keto diet is a popular weight-loss strategy, especially for bariatric patients. It involves a significant reduction in carbohydrate intake and a corresponding increase in fat consumption. This dietary shift can lead to rapid weight loss in the initial weeks, primarily due to reduced water retention and the body's transition to burning fat for energy.

Initial Rapid Weight Loss

During the first week of the keto diet, individuals often experience a rapid drop in weight, ranging from a few pounds to as much as 10. This initial loss is largely attributed to the body shedding water weight. Carbohydrates bind with water in the body, and when carb intake is restricted, the body releases this stored water, leading to noticeable weight loss on the scale.

However, it's important to distinguish between water weight loss and fat loss. While the initial phase of the keto diet may show promising results, it's not indicative of long-term fat loss. The rapid water loss may also lead to dehydration and constipation, so staying adequately hydrated is crucial during this period.

Transition to Ketosis

As the body depletes its glycogen stores, it transitions to a metabolic state called ketosis, where it starts burning fat for energy instead of carbohydrates. This shift typically occurs within a week of starting the keto diet, but it may take longer for some individuals. During this transition, many people continue to experience dramatic weight loss.

Long-Term Weight Loss

After the initial rapid weight loss phase, weight loss on the keto diet tends to stabilize, and the rate of loss slows down. At this point, the body is fully fat-adapted and primarily burning fat for energy. Weight loss varies depending on how long an individual stays on the keto diet, their starting weight, and their overall health condition.

Research has shown that obese patients can lose significant weight on the keto diet. One study found that obese patients lost an average of 30 pounds after two months on the keto diet, with over 88% of patients losing more than 10% of their initial weight. Another study reported an average weight loss of 33 pounds over 5.5 months.

The keto diet can be unhealthy if it includes too many saturated fats

The ketogenic diet is a popular choice for weight loss, and it has been touted as a particularly effective method for bariatric patients. The diet involves a very low carbohydrate and high-fat intake, which can lead to the body burning fat for energy instead of carbohydrates. While the keto diet can be effective for weight loss, it may not be the best option for bariatric patients due to the high amount of saturated fats often included in the diet.

Saturated fats are typically solid at room temperature and are found in animal-based foods like beef, pork, and dairy products, as well as tropical oils like coconut oil. These types of fats have been linked to an increased risk of heart disease and other health problems. When consumed in excess, saturated fats can raise LDL cholesterol levels in the blood, which is a risk factor for heart disease and stroke. Additionally, high-fat foods that are commonly included in the keto diet, such as bacon, cheese, and red meat, can be high in saturated fat and add extra calories to the diet, leading to weight gain.

For bariatric patients considering the keto diet, it is important to be mindful of the types of fats included in the diet. While the diet may be effective for weight loss, it is crucial to prioritize nutrient-rich, whole foods and limit the consumption of saturated fats to maintain overall health and well-being. A modified version of the keto diet that includes healthier sources of fat, such as nuts, seeds, and avocado, may be a better option for bariatric patients. It is always recommended to consult with a healthcare professional before starting any new diet, especially for those with specific health concerns or dietary restrictions.
