Keto And Bariatric Surgery: A Powerful Weight Loss Combination

Bariatric sleeve surgery, also known as gastric sleeve surgery or sleeve gastrectomy, is a procedure that removes a large portion of the stomach, leaving behind a narrow sleeve. This restricts the amount of food that can be eaten and reduces hunger signals. On the other hand, the keto diet, short for ketogenic diet, is a low-carb, high-fat diet that aims to force the body into using fat for energy instead of carbohydrates. This is done by drastically reducing carbohydrate intake and replacing it with fat, which puts the body into a metabolic state called ketosis. Both methods have been shown to be effective for weight loss, with the gastric sleeve being the most commonly performed weight loss surgery in the US and worldwide, and the keto diet gaining popularity as a weight-loss wonder.

Bariatric sleeve surgery: the stomach is stapled and reshaped, removing around 80% of it

Bariatric Sleeve Surgery: Stomach Stapling and Reshaping

Bariatric sleeve surgery, also known as sleeve gastrectomy, is a procedure that involves reducing the size of the stomach by around 80%. This is achieved by stapling and reshaping the stomach, resulting in a sleeve-like structure. This type of bariatric surgery is an effective weight loss method as it alters the interaction between ingested carbohydrates and the gastrointestinal tract.

During the surgery, a large portion of the stomach is removed, leaving a thin vertical sleeve, or tube, in its place. This new, smaller stomach is then stapled together to ensure it holds its shape and size. The procedure is typically performed laparoscopically, using small incisions and specialised instruments to access and manipulate the stomach.

By reducing the stomach size, the surgery restricts the amount of food that can be consumed at one time, leading to a decrease in calorie intake. Additionally, the surgery also alters the body's production of certain gut hormones, such as GLP-1, which play a crucial role in glucose metabolism, satiety control, and weight loss. This hormonal change further contributes to increased feelings of fullness and improved blood sugar control.

The procedure is often recommended for individuals with severe obesity and can lead to significant weight loss. However, it is important to note that bariatric sleeve surgery is just one aspect of a comprehensive weight loss plan. Patients typically need to commit to long-term lifestyle changes, including adopting healthier eating habits and increasing physical activity, to ensure sustained weight loss and improved health outcomes.

Keto: a high-fat, low-carb diet that changes the way your body burns energy

The keto or ketogenic diet is a high-fat, low-carb diet that has gained popularity as a weight-loss method. The diet involves significantly reducing carbohydrate intake and replacing those calories with natural fats like olive oil, avocado, grass-fed meat, and butter. This shift in macronutrient ratios changes the way the body burns energy, potentially leading to weight loss.

Under normal circumstances, the body breaks down carbohydrates to use glucose as its primary energy source, while fat is stored. The keto diet aims to switch the body's primary energy source from glucose to fat by severely restricting carbohydrate intake. This restriction causes the body to enter a state called ketosis, where it burns stored fat for energy instead of glucose, resulting in the production of ketones as a primary fuel source.

The Benefits of Keto

The keto diet has gained popularity due to its ability to promote rapid weight loss. Some people have claimed to lose over 40 pounds after years of unsuccessful dieting. In addition to weight loss, the keto diet may offer other potential benefits, such as improved blood glucose control and increased energy and focus. It has also been researched for its effectiveness in treating seizure disorders in children.

The Challenges of Keto

While the keto diet can be effective for weight loss, it is not without its challenges and potential downsides. The diet is very restrictive and can be difficult to follow long-term. Carbs typically represent around 50% of daily food intake, but on the keto diet, they are restricted to around 5%. This means saying goodbye to bread, pasta, french fries, sweet potatoes, and most fruits. The high-fat content of the keto diet can also lead to unwanted side effects, especially if unhealthy fats are chosen over healthy options like nuts, seeds, salmon, extra virgin olive oil, and avocados.

Additionally, the keto diet may not provide adequate protein and fiber, which are essential for digestive processes and muscle maintenance. It can also lead to an imbalance in thyroid hormones and nutrient malabsorption, especially in those with prior thyroid issues. Some people may experience the "keto-flu," which includes symptoms like brain fog, headaches, fatigue, irritability, nausea, and constipation, due to the body's metabolic adjustments to breaking down fats for energy.

Keto and Bariatric Surgery

The keto diet has gained popularity among bariatric patients, but it may not be suitable for everyone. Bariatric surgery, such as gastric bypass, alters the normal physiology of the digestive tract, and a bariatric diet that is maintainable for life is crucial for long-term success. The keto diet can be challenging to follow post-bariatric surgery due to the high-fat content and the need for modifications to include adequate protein and fiber. It is important for bariatric patients considering the keto diet to consult with a medical professional and make the necessary adjustments to ensure a safe and effective approach to weight loss and improved health.

Bariatric sleeve surgery: a less complicated alternative to gastric bypass surgery with a lower risk of complications

Bariatric surgery is a procedure that helps with weight loss. It is an option for those who need to lose a lot of weight, especially if other methods such as improving diet, increasing physical activity, and taking weight loss medications have not worked. Two of the most common types of bariatric surgery are gastric sleeve surgery and gastric bypass surgery.

Gastric sleeve surgery

Gastric sleeve surgery, also known as sleeve gastrectomy, is a restrictive surgery that reduces the amount of food one can eat, helping them feel full sooner. During the procedure, a surgeon permanently removes about 80% of the patient's stomach, and the remaining 20% is sewn into a small, banana-shaped pouch. This reduces the volume of the stomach, making it difficult to overeat and easier to feel satisfied after small meals.

Gastric bypass surgery

Gastric bypass surgery, or Roux-en-Y gastric bypass surgery, is both restrictive and malabsorptive. It reduces the amount of food one can eat and prevents the body from absorbing too many calories. During the procedure, the surgeon creates a small stomach pouch by removing most of the stomach and the first part of the small intestine. The newly created stomach pouch is then reconnected to the remaining small intestine, bypassing the lower part of the stomach. This results in a reduced absorption of calories, contributing to weight loss.

Comparison

Both procedures have similarities, as they both reduce the stomach to a small pouch, causing weight loss by restricting food intake and reducing the production of the hunger hormone, ghrelin. However, they differ in the way the new stomach pouch is created. Gastric sleeve surgery is less complicated than gastric bypass surgery, as it only involves one step compared to the two-step procedure of gastric bypass. As a result, gastric sleeve surgery has a shorter recovery time of 2 to 3 weeks, compared to 4 to 6 weeks for gastric bypass.

In terms of weight loss results, gastric bypass patients can expect to lose between 50 to 80% of their excess body weight within 12 to 18 months, while gastric sleeve patients typically lose weight at a slower and steadier rate, losing 60 to 70% of their excess body weight in the same time frame. Gastric bypass surgery is generally recommended for very obese patients with a Body Mass Index (BMI) over 45.

Risks and complications

Bariatric surgery is considered a relatively safe procedure, with a low risk of major complications of about 4%. However, all surgeries carry some risks, including hemorrhage, deep vein thrombosis, pulmonary embolism, side effects of anesthesia, and infection. Possible complications specific to bariatric surgery include leakage of stomach fluid, nutritional deficiencies, and dumping syndrome, which is rapid gastric emptying that can cause nausea, sweating, and severe diarrhea.

Gastric sleeve surgery has a lower risk of dumping syndrome compared to gastric bypass. Additionally, gastric bypass surgery carries a higher risk of gastroesophageal reflux disorder (GERD), which causes acid reflux, and an increased sensitivity to alcohol.

Keto: not a typical Western diet, keto diets are high in fat and very low in carbohydrates

The keto diet is not a typical Western diet. It is a high-fat, very low-carbohydrate diet that is often used for weight loss and to manage certain health conditions. Here are some key points about the keto diet:

• The keto diet is a significant departure from the typical Western diet, which is usually around 30% fat, 15% protein, and 55% carbohydrates. In contrast, the keto diet consists of approximately 60-70% fat, 20-30% protein, and only about 10% carbohydrates.
• This diet involves drastically reducing carbohydrate intake and replacing it with fat. This shift in macronutrient ratios puts the body into a metabolic state called ketosis, where it burns fat for energy instead of carbohydrates.
• Ketosis can lead to a reduction in blood sugar and insulin levels, which is beneficial for people with type 2 diabetes, prediabetes, and metabolic syndrome.
• The keto diet is not just about eating more fat; it is important to choose healthy fats. Unsaturated fats, such as nuts, seeds, avocados, and olive oil, are recommended. However, saturated fats from oils, lard, butter, and cocoa butter are also consumed in high amounts on the keto diet.
• Protein intake on the keto diet is moderate. While the diet includes protein sources like meat, fish, and eggs, it is important not to consume too much protein as it can interfere with ketosis.
• Carbohydrate intake on the keto diet is limited to around 20-50 grams per day. This means avoiding sugary foods, grains, starches, most fruits, beans, legumes, root vegetables, and high-carb vegetables like potatoes and carrots.
• The keto diet has potential health benefits beyond weight loss. It may improve risk factors for heart disease, reduce seizures in epileptic children, and have a positive impact on Alzheimer's disease, Parkinson's disease, and polycystic ovary syndrome.
• However, the keto diet also has some potential risks and side effects. These include nutrient deficiencies, liver and kidney problems, constipation, and fuzzy thinking. It is important to consult a healthcare professional before starting the keto diet, especially if you have any health concerns.

Bariatric sleeve surgery: a weight-loss surgery for people with clinically severe obesity

Bariatric surgery is the most effective treatment for clinically severe obesity in terms of durable weight loss and the reduction of comorbidity burden and mortality. It is a safe and effective approach to induce weight loss.

There are different types of bariatric surgery, including gastric sleeve surgery, gastric bypass, and duodenal switch. These procedures alter the normal physiology of the digestive tract, reducing the size of the stomach and bypassing parts of the small intestine. This leads to changes in gut hormone secretion, such as GLP-1, resulting in increased satiety and improved postprandial glucose metabolism.

One type of bariatric surgery is the vertical sleeve gastrectomy (VSG), which involves removing a portion of the stomach to restrict food intake and promote weight loss. This procedure is often recommended for patients with severe obesity and can lead to significant weight loss and health improvements.

The ketogenic diet (keto) has also gained popularity as a weight-loss method. Keto involves a high-fat, moderate-protein, and very low-carbohydrate approach. This diet aims to induce a state of ketosis, where the body burns fat for energy instead of glucose. While keto can lead to rapid weight loss, it is very restrictive and may not be sustainable or suitable for everyone.

For individuals who have undergone bariatric surgery, a post-operative diet typically focuses on high protein, low carbohydrate, and low-fat foods. This approach ensures adequate nutrition and supports the body's changing needs during the weight-loss journey.

In summary, bariatric sleeve surgery is a safe and effective treatment for clinically severe obesity, leading to durable weight loss and improved health outcomes. While keto can also induce weight loss, it may not be suitable for everyone and should be approached with caution, especially for those with prior health conditions.
