Intermittent fasting is a popular eating pattern where you cycle between periods of eating and fasting. For those with an ileostomy, it can be a bit different, but many have found success with it. Here are some experiences and tips from people who have tried intermittent fasting with an ileostomy:

- 12–14-hour fasts:
- Many people stop eating between 5 pm and 8 pm and then eat again between 7 am and 9 am, fasting for 12 to 14 hours. They have noticed:
- No significant change in their colostomy or ileostomy output.
- Improved sleep when they eat earlier in the evening, as eating late can increase nighttime output.

- 16-hour fasts (with an 8-hour eating window):
- A common routine is to have the last meal at 8 pm and the first meal at noon the next day.
- Benefits reported include steady weight loss, with some aiming for around 7 pounds, and better control over portion sizes. The ileostomy generally behaves well during this routine.

- Two-meal schedule with a 16-hour fast:
- An example schedule includes breakfast between 8 and 9:30 am, after having two cups of coffee, and a "lupper" (lunch/supper) between 3 and 4 pm, with no food after 4 pm.
- This approach has led to a 15-pound weight loss, though some weight may return during vacations with more frequent meals. However, the weight tends to come off again once the fasting routine is resumed.

- Extended fasts (20-hour):
- One person eats within a 4-hour window to manage a strong family history of diabetes.
- Combined with daily walking, this fasting method helps maintain an A1c level of 4.6–4.7, even with a diet high in carbs and less healthy foods.

- Tips for adaptation and comfort:
- Gradually increase fasting hours instead of jumping straight to long fasts.
- Some use Bulletproof Coffee for energy during fasting; it may take about a week to get used to it.
- Small amounts of applesauce can be taken with morning supplements without affecting fasting results.
- Flexibility is key: occasional treats like ice cream or take-out can still fit into the overall fasting plan.

- General observations:
- Intermittent fasting significantly helps with weight control, though progress can be slower if exercise is limited due to injuries.
- Eating the final meal earlier, around 5 to 6 pm, can reduce nighttime stoma activity and improve sleep quality.
