Eat smaller meals more frequently Many people with IBS tend to have better luck eating four to six smaller meals a day, compared to the standard three large meals. That's because filling your stomach in one sitting can make digestion more challenging.
Eat more fiber
The Dietary Guidelines for Americans, 2020–2025 recommends that adults should get 22 to 34 grams of fiber a day. Research suggests that soluble fiber is more helpful in relieving IBS symptoms. To help your body get used to more fiber, add foods with fiber to your diet a little at a time.
On average this means it takes about 6-24 hours from the time food is eaten until it reaches the colon where FODMAPs are fermented, resulting in IBS type symptoms.
This is why smaller meals can help IBS
Some people with IBS find that eating more smaller meals, which are more evenly balanced in size, helps to keep their symptoms more stable. So if you find that one or more of your meals are larger than your other meals, you may like to try eating smaller meals more often.
You can ease your IBS symptoms by eating a balanced diet that is low in FODMAPs and saturated fat. These include lean meats, eggs, fatty fish, leafy greens, nuts, seeds, and fruits that are lower in sugar. Fermented foods may also be good for the gut flora in you have IBS.

It's the way that you eat it
If you are anxious, frustrated or on the go when you are digesting a meal, the emotions will tend to upset the gut and cause symptoms of IBS. People who miss out on meals and then gorge themselves on high fat foods with lots of beer or wine are playing havoc with their irritable bowels.
