Also, try not eating anything that is hard to digest like beef and poultry, and cheese for a period of time. Fish, egg whites, Lactaid nonfat milk, and pea protein isolate are easy to digest. Consider avoiding grains for a period of time.

Also look at your supplements. Any fiber supplement that says it is also good for weight loss does this by slowing down your digestion. Also check your prescription meds for such side effects.

Also, consider gut massage. See England's National Health Service guide:

Consider trying easy-to-digest soups and hot cereals. Consider sipping H20 throughout the day or a hot drink. Also consider eating low or zero FODMAP foods (per Monash University FODMAP app).

Keep at it -- something will help.

When I was a kid, my mom used mineral oil on salads and I hated having to eat her salads. My friends parents used olive oil and I could eat a salad. I still can taste the awful salads my mom made me eat. Sooooooooo, don't want to use mineral oil for anything. Unless it comes in pill form.
