The ketogenic diet, or keto, is a high-fat, low-carbohydrate diet that aims to put the body in a state of ketosis, where it burns fat for energy instead of carbohydrates. On the other hand, a low-FODMAP diet is designed to help identify trigger foods that cause symptoms of irritable bowel syndrome (IBS) and other gastrointestinal issues. FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, which are types of sugars found in various foods. While keto and low FODMAP are two different diets with distinct purposes, they are compatible. Many foods excluded on the keto diet are also high in FODMAPs, making it easier to follow both diets simultaneously. For example, keto dieters avoid grains, high-sugar fruits, and certain vegetables, which also tend to be high in FODMAPs. Combining the two diets can be beneficial for those with IBS who are also interested in weight loss or improving blood sugar control.

The keto diet and low FODMAP diets eliminate some of the same foods
The keto and low FODMAP diets are two entirely different diets, with different purposes. However, they are compatible, and some people choose to follow both diets at the same time. The keto diet is a high-fat, low-carbohydrate diet, which aims to put your body in a state of ketosis, where it burns fat instead of carbohydrates for energy. The low FODMAP diet, on the other hand, is a temporary elimination diet designed to help people identify trigger foods that cause irritable bowel syndrome and other gastrointestinal issues.
The keto diet and low FODMAP diets do eliminate some of the same foods. For example, the keto diet restricts grains, high-sugar fruits and vegetables, honey, sugar, syrup, and products containing these sweeteners. The low FODMAP diet also eliminates wheat, legumes, dairy, and many types of added sugars. As such, over 75% of the foods on the "High-FODMAP Foods to Avoid" list are already excluded from the keto diet. This means that if you are already on the keto diet, it will be easier to transition to a low FODMAP diet, as you won't have to eliminate as many foods.
Both diets can be challenging, especially when it comes to identifying which foods are suitable. For the keto diet, this is relatively straightforward, as you can avoid grains, sugars, and starchy fruits and vegetables. However, for the low FODMAP diet, it can be extremely difficult to identify the FODMAP content of a food without specialised lab equipment or an app like Monash FODMAP. This is because FODMAPs include a wide range of molecules, such as oligosaccharides (found in wheat, onions, and beans), disaccharides (lactose in dairy), monosaccharides (fructose in fruit), and polyols (artificial sweeteners).
Despite the challenges, it is possible to follow both diets at the same time, and there are resources available to help. For example, there are low FODMAP keto recipe ideas and low FODMAP keto products available, such as salad dressings, marinades, and salsas. Additionally, there are printable keto low FODMAP food lists available online, which can be useful when grocery shopping or planning meals.

The keto diet is high fat, low carbohydrate, and restricts grains, starches, and sugars
The low-FODMAP diet, on the other hand, is designed to help identify trigger foods that cause symptoms of irritable bowel syndrome (IBS) and other gastrointestinal issues. It involves eliminating high FODMAP foods, which include wheat, legumes, dairy, and added sugars. FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, which are types of sugars found in a wide range of foods.
The keto and low-FODMAP diets are two different diets with distinct purposes. However, they are compatible, as many of the foods restricted on the keto diet are also high in FODMAPs. For example, grains, starches, and sugars are restricted on both diets. Therefore, it may be easier to transition to a low-FODMAP diet if you are already following a keto diet.
Combining the keto and low-FODMAP diets can be challenging due to the restrictive nature of both diets. However, it is possible to find recipes and foods that adhere to both diets, such as meats, nuts, seeds, cheese, and low-carb vegetables. Additionally, cooking techniques that are typically forbidden in other diets, such as frying foods in butter or oil, are encouraged on the keto diet.
It is important to note that the keto and low-FODMAP diets should not be considered long-term solutions. The keto diet, in particular, can be unhealthy if followed for an extended period due to its high-fat content. The low-FODMAP diet is meant to be followed temporarily to identify trigger foods, after which high-FODMAP foods can be gradually reintroduced.

The low FODMAP diet eliminates wheat, legumes, dairy, and added sugars
The low FODMAP diet is an elimination diet designed to help people with irritable bowel syndrome (IBS) and other functional gastrointestinal disorders identify food triggers. It was developed by researchers at Monash University in Australia in the early 2000s. The diet has three phases: elimination, reintroduction, and maintenance. During the elimination phase, high-FODMAP foods such as specific fruits, vegetables, dairy products, and grains are avoided. After two to four weeks, the reintroduction phase begins, where these foods are systematically added back into the diet. The maintenance phase involves keeping the foods that work for the individual and leaving out the ones that don't.
FODMAP is an acronym for "fermentable oligosaccharides, disaccharides, monosaccharides, and polyols." These are types of short-chain carbohydrates that are resistant to digestion and can trigger digestive symptoms such as gas, bloating, stomach pain, diarrhea, and constipation. Wheat, legumes, and dairy are common sources of FODMAPs. Wheat products, including biscuits, bread, breakfast cereals, crackers, pancakes, pasta, tortillas, and waffles, are high in FODMAPs. Legumes such as beans, lentils, chickpeas, and soybeans are also high in FODMAPs. Dairy products like milk, yogurt, ice cream, and soft and fresh cheeses are rich in lactose, a disaccharide FODMAP.
Additionally, the low FODMAP diet eliminates many types of added sugars. FODMAPs include monosaccharides like fructose, found in table sugar and added sugars, and polyols, which are sugar alcohols used as artificial sweeteners. The diet does not aim to completely eliminate FODMAPs but rather to minimize their consumption to reduce digestive symptoms. It is important to note that not everyone has a sensitivity to FODMAPs, but it is prevalent among people with IBS.
Combining the low FODMAP diet with the ketogenic (keto) diet is possible, as they are compatible. The keto diet is high in fat and protein and low in carbohydrates, which overlaps with the low FODMAP diet's restriction of certain carbohydrates. However, it is recommended to start with the low FODMAP diet first before transitioning to keto, as eliminating FODMAPs can already be challenging.

The keto and low FODMAP diets have different purposes but are compatible
The ketogenic diet, or keto, is a high-fat, low-carbohydrate diet. It was initially developed in the 1920s and 1930s to manage children's epilepsy. In recent years, it has become popular as a weight-loss diet. The keto diet involves burning fat for energy instead of carbohydrates, which are limited. This state is called "ketosis".
The low FODMAP diet, on the other hand, is an elimination diet designed to help people identify trigger foods that cause symptoms of irritable bowel syndrome (IBS) and other gastrointestinal issues. FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols—molecules that people with IBS have difficulty digesting. The diet was developed by researchers in Australia.
While the keto and low FODMAP diets have different purposes, they are compatible. Over 75% of the foods on the "High-FODMAP Foods to Avoid" list are already excluded from the keto diet. Therefore, if you are already on the keto diet and want to try a low FODMAP diet, it will be easier to eliminate the necessary foods. Additionally, the keto diet avoids processed foods, making it easier to combine with a low FODMAP approach.
However, it is important to note that the low FODMAP diet is extremely restrictive, and it is not meant to be followed forever. The goal is to eventually reintroduce high-FODMAP foods and identify specific trigger foods, rather than avoiding FODMAPs altogether long-term. If you are considering starting a low FODMAP diet, it is recommended to eliminate FODMAPs before starting keto.
There are many resources available for those interested in combining the keto and low FODMAP diets, including recipes, meal plans, and food lists.

The low FODMAP diet is temporary and helps identify trigger foods for IBS and gastrointestinal issues
The low FODMAP diet is a temporary and restrictive dietary plan that helps people with irritable bowel syndrome (IBS) and other gastrointestinal issues identify trigger foods. FODMAP is an acronym for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, which are short-chain carbohydrates (sugars) that the small intestine absorbs poorly. These sugars are found in a wide range of foods, including fruits, vegetables, wheat, dairy, legumes, and nuts, and can cause intestinal distress in those with IBS.
The low FODMAP diet was developed by researchers at Monash University in Australia in the early 2000s. It is a recommended first-line treatment for people diagnosed with IBS, as it helps improve digestive comfort and overall health. The diet typically begins with a strict 2-6 week elimination phase, where high FODMAP foods are avoided. During this initial restrictive phase, IBS patients may experience improvements in their symptoms, including reduced intestinal bloating, gas, and pain.
After the elimination phase, the diet transitions to a reintroduction phase, where high FODMAP foods are gradually added back into the diet, one at a time, every 3-4 days or longer. This allows individuals to identify specific trigger foods that cause their IBS or gastrointestinal symptoms to flare up. By systematically reintroducing different food groups, individuals can determine which high FODMAP foods they can tolerate and which they need to avoid in the long term.
It is important to note that the low FODMAP diet is not meant for weight loss, despite the potential for weight loss due to the elimination of many foods. Additionally, it is not a permanent solution, and individuals should work closely with a qualified dietitian or healthcare professional experienced in this specialized area to ensure safe and effective implementation of the diet. While the low FODMAP diet has shown promising results, it does not work for everyone with IBS, and other dietary therapies or treatments may need to be explored in conjunction with or as an alternative to the low FODMAP approach.

Frequently asked questions
The ketogenic diet, or keto, is a high-fat, low-carbohydrate diet that is designed to put your body in a state of ketosis. In ketosis, your body doesn't have enough carbohydrates to burn for energy, so it burns fat instead.
A low FODMAP diet is a temporary elimination diet designed to help identify potential trigger foods that could be causing symptoms of irritable bowel syndrome and other gastrointestinal problems. FODMAP is short for "fermentable oligosaccharides, disaccharides, monosaccharides, and polyols."
Yes, it is possible to follow a keto diet while also adhering to a low FODMAP diet. The keto diet and low FODMAP diets eliminate some of the same foods, such as sugars, certain starches, grains, and high-carb fruits and vegetables. However, combining the two diets can be challenging due to their restrictive nature.
Some keto-friendly foods that are also low in FODMAPs include meats like beef, pork, chicken, and salmon; nuts and seeds; cheeses; and low-carb vegetables like zucchini, red pepper, broccoli, bok choy, and cauliflower.
Combining the keto and low FODMAP diets can help address a range of symptoms, including autoimmune-related issues, inflammation, gas, constipation, diarrhea, bloating, and stomach pain. The keto diet is often associated with weight loss, improved blood sugar control, and potential reduction in certain diseases, while the low FODMAP diet has been shown to improve negative digestive symptoms in individuals with IBS and other gastrointestinal issues.
