There are many blogs, diet plans, videos, etc floating on the internet for Weight Loss. But, there is a certain group of people for whom these articles and videos are of no use. They are people who are struggling with Weight Gain. Extremely lean and underweight people may have low immunity, infertility, fragile bones, and malnutrition. Gaining Weight in Irritable Bowel Syndrome (IBS) is even more challenging. IBS patients especially with Diarrhea as common symptoms, have a hard time gaining weight as their body is unable to absorb the nutrients from the food. Be assured with the correct diet and lifestyle you can gain a healthy weight in IBS.
How to gain weight in IBS?
Maintaining a healthy weight is important for health. It lowers the risk of heart diseases, stroke, diabetes, high blood pressure, and various cancers. People suffering from IBS struggle to maintain a healthy weight. Frequent bouts of diarrheas and loss of appetite in IBS can cause loss of weight. Weight loss also occurs due to strict diet restrictions to cope up with the disorder. Neglecting weight loss in IBS can further lead to many other problems due to Malnutrition.
If you are thinking gaining weight is easy compared to losing weight then you are extremely wrong!! Weight gain must be done scientifically like weight loss. You must detox your body and then reboot it again with a proper diet and lifestyle for proper weight gain. Do not overdo with sugar and fats to gain weight, this will cause serious health complications. Focus on building muscle instead of increasing fat content in the body. (1) (2)
If you are noticing drastic weight loss within a few days of starting the restricted IBS diet plan, contact your physician immediately.
Three tips to gain weight with IBS in a healthy way.
- Correct Diet
Finding the correct diet through eliminating and reintroducing certain foods can help you manage a healthy weight in IBS. Stick to LOW FODMAP’s food while planning the meal for you. There are no fixed guidelines for increasing weight in IBS through diet. Foods that can help an individual may cause serious digestive disturbances in others. Try to figure your food allergies, intolerances, and tolerance level of each food item before concluding your meal plan for weight gain.(3) (4) (5)
A qualified nutritionist or Dietitian can help you to make a tailor-made diet plan for improving your IBS symptoms and achieving a healthy weight.
- Focus on protein intake :
Protein can help in building muscles so stocking up on them can help gain weight. Even smooth muscles that make the gastrointestinal tract function smoothly require good protein sources. High-protein foods are not only important for weight loss but they are important for weight gain as well.
The following table shows the good source of proteins from Animal and Plant sources for gaining healthy weight in IBS without triggering IBS symptoms.
|Animal Proteins Safe for IBS||Plant Proteins safe for IBS|
|Chicken (skinless)||Tofu (in moderate amount) and cottage cheese|
|Eggs||Lentils (in moderate amount) – Moong Dal and Masoor Dal|
|Seafood||Chickpeas (In small quantities)|
|Low-fat Beef||Nuts like Brazil Nuts, Almonds|
|Low – Fat Milk (If not lactose intolerant)||Seeds like Sunflower, Sesame, and Chia seeds|
|Half a teaspoon of Peanut.|
|Almond milk, Oat milk and Rice Milk.|
- Focus on Healthy Fats :
Fats help in weight gain as they contribute more calories than Carbohydrates and Proteins. If an IBS patient isn’t sensitive and can tolerate fats well, then you can include 20-30% of your calories from Fats and Oils. Other than being a source of energy, Fats are also required for Proper Functioning of the Brain, Protecting your organs, carrying fat-soluble vitamins, and muscle building.
Adding an extra dose of fat doesn’t mean increasing oil while preparing your meals, if you overdo oils in cooking then it may trigger IBS symptoms. Instead, you can add a teaspoon of olive oil on your salads (boiled) or a teaspoon of go ghee on your Idly or Kuttu ka Roti.
Not all the fats from food are the same. So, include only healthy oils and fats.
|Fats to Exclude in IBS||Fats to Include in IBS|
|Trans Fat ( Present in all processed foods)||Coconut Oil|
|Hydrogenated Oils||Extra virgin olive oil|
|Saturated Fats ( In red meat and butter)||Fruits like olives|
|Deep-fried and Greasy foods||Seeds like flax and chia|
|Nuts like pecans and Walnuts|
|Fishes – Salmon and Sardines|

Choose fruits and vegetables which are low in FODMAP’s. Consult your physician or Qualified Dietitian to help you with supplements in case of severe malnutrition and deficiencies.
- Fiber Foods :
Fiber is very essential to keep the Gut healthy. Fiber tolerance is different for different people. Certain people tolerate well with insoluble fiber whereas for others it can worsen the IBS symptoms. It is also been observed that few individuals cannot tolerate soluble fiber from beans. Your dietitian can recommend Soluble Fiber supplements if you are unable to tolerate the fiber from the foods.

Hydration plays a crucial role in dealing with IBS. It is compulsory to consume 3 liters of fluid every day. Water soothes stomach distress.
