The Ultimate Low FODMAP Keto Food List: What to Eat on a Low FODMAP Ketogenic Diet
The low FODMAP diet and keto diet have both become quite popular for improving digestive health and promoting weight loss. Many people find benefits combining key aspects of both diets into one low FODMAP ketogenic diet plan.
This hybrid diet aims to get the gut-friendly perks of a low FODMAP diet along with the metabolic benefits of ketosis. However, it requires careful selection of low FODMAP foods that also fit keto macronutrient guidelines.
This complete low FODMAP keto food list outlines the optimal foods to enjoy and avoid on a gut-soothing, fat-burning low FODMAP ketogenic diet.
Understanding the Low FODMAP Diet
FODMAPs are certain carbohydrates that may cause digestive issues for some people. FODMAP stands for:
- Fermentable - broken down by bacteria in the large intestine
- Oligosaccharides - fructans and galactooligosaccharides (GOS)
- Disaccharides - lactose
- Monosaccharides - fructose
- And Polyols - sugar alcohols like sorbitol, mannitol, xylitol, maltitol
A low FODMAP diet eliminates high FODMAP foods. It is clinically proven to relieve common IBS symptoms like gas, bloating, abdominal pain, diarrhea and constipation.
Key Rules of a Keto Diet
The ketogenic or “keto” diet is centered around getting 70-80% of calories from fat. This pushes the body into ketosis, where ketones rather than glucose become the main fuel source. Benefits can include:
- Weight loss and reduced hunger
- Stable blood sugar levels
- Improved mental focus and energy
- Better cholesterol markers
Protein intake should be moderate at 15-20% of calories. Carbohydrates are restricted to just 5-10% of calories, limiting to 20-50g net carbs daily.
Combining Low FODMAP and Keto
Both diets eliminate certain carbohydrates which makes combining them fairly straightforward. You still restrict high FODMAP foods but focus on low FODMAP options that fit into keto macronutrient ratios.
Potential benefits of a hybrid low FODMAP keto diet include:
- Relief from IBS and digestive issues
- Reduced inflammation
- Improved gut bacteria balance
- Increased fat burning and weight loss
- Better blood sugar regulation
- Diminished cravings
Following a very strict keto diet may actually worsen gut symptoms initially. A modified approach limiting only high FODMAP carbs allows you to go lower carb while supporting digestive health.
