Key Points
- What you eat and drink throughout the day can provide fiber and fluids to your gut.
- A lentil grain bowl topped with avocado and cooked vegetables plus two kiwis is the best lunch.
- Taking a walk after a meal and setting aside time for a bowel movement may also help.
Missing your usual morning poop can leave you feeling backed up, bloated and possibly distracted by what hasn’t happened. There’s no need to make a big stink over one missed bowel movement, but what you eat and drink throughout the day can help provide the fiber and fluids your digestive tract needs to produce softer, easier-to-pass stools.
According to the dietitians we spoke with, a lunch built around a lentil grain bowl, topped with avocado and cooked vegetables, paired with two green kiwis and a large glass of water is the best meal to get things moving. The meal provides a mix of fibers, plenty of fluid and kiwi, a fruit that has been specifically studied for constipation. Keep reading to learn how each part of the meal can support easier bowel movements and what else you can try if lunch alone doesn’t do the trick.
Why This Lunch May Help You Poop
It Provides a Mix of Fibers
Lentils, whole grains, vegetables, avocado and kiwi work together because each contributes a different mix of fiber. Avocado and kiwi provide soluble fiber that holds onto water and helps to soften stool, while lentils, whole grains and vegetables supply insoluble fiber, which adds bulk and helps stool move through your digestive tract. “Insoluble fiber adds bulk to stool, while soluble fiber absorbs water to soften it. Together, they support healthy bowel movements,” says Lavanya Kethamukkala, RDN, CLT, LDN.
The whole-grain base may further support that effect. In fact, research suggests that adults who consume a diet rich in whole grains may have more frequent bowel movements than those who consume more refined grains. This means that whole grains may contribute to softer, more frequent stools. The benefit is more likely to build with consistent intake, though, rather than happen after a single lunch.
Kiwi May Help Support Regularity
The two green kiwis may be the most evidence-backed component of this specific lunch. “The bowel movement star of the show is kiwi, which is a surprising friend for regularity,” says Maggie Moon, M.S., RD.
Research suggests that eating two green kiwis daily may increase spontaneous bowel movements and improve gastrointestinal comfort in people with constipation. The research looked at consistent kiwi intake over several weeks, so it doesn’t mean eating two kiwis at lunch will necessarily make you poop that afternoon. Instead, it suggests that regularly including kiwi may support healthier bowel habits over time.
Two kiwis also provide a meaningful amount of fiber and can be an easy addition to lunch or an afternoon snack. You can eat both with lunch or split them between lunch and a snack if the full meal feels like too much food in a single sitting, suggests Kethamukkala.
Water Helps to Soften Stool
This lunch provides a substantial amount of fiber, which works best when you’re also getting enough fluid. Soluble fiber from the lentils, avocado and kiwi absorbs water as it moves through your digestive tract, while insoluble fiber adds bulk. Without enough fluid, increasing your fiber intake may not have the desired effect—and can sometimes make constipation worse.
“Think about fiber like a sponge. It can only soften the stool if there is water for it to absorb,” says Angela Graham, M.B.A., RDN. “Constipation can actually get worse with increased fiber intake without enough fluids,” she explains.
Enjoy the grain bowl with a large glass of water, then continue drinking regularly throughout the day. The goal is not to reach a specific water quota at lunch, but to make sure the meal’s fiber is accompanied by adequate fluid rather than adding a large amount of fiber to an otherwise low-fluid day.
It Can Be Adjusted to Your Fiber Tolerance
This bowl contains several high-fiber foods, but you do not need to pile every ingredient onto your plate to benefit. A sudden jump in fiber intake can leave you feeling more bloated or gassy, especially if you’re not used to eating a lot of fiber.
“When it comes to fiber, more isn’t always better. Your gut responds better to steady intake than one giant fiber-packed meal,” says Kethamukkala. She recommends using half an avocado and saving one of the two kiwis for a later snack if the full meal feels like too much at once.
You can also start with a smaller portion of lentils, choose cooked rather than raw vegetables and gradually increase the amount of fiber in your diet as your body adjusts. This keeps the lunch focused on consistent fiber intake instead of trying to force a bowel movement with an unusually large fiber load. Pair whatever portion you choose with water, since increasing fiber without enough fluid may make hard stools more difficult to pass.
Other Strategies to Support Digestive Health
Lunch can contribute fiber and fluid, but your overall eating pattern, physical activity and bathroom habits can also affect bowel regularity. Try these strategies alongside a consistent fiber-rich diet:
- Take a walk. Regular physical activity may help relieve constipation symptoms. Even a short walk after lunch can add movement to an otherwise sedentary day.
- Give yourself time after breakfast. Eating stimulates bowel activity, making the period after a meal a useful time to try to have a bowel movement. Set aside a regular bathroom time about 20 to 40 minutes after breakfast and give yourself time to sit on the toilet without rushing.
- Don’t ignore the urge to go. Repeatedly postponing a bowel movement can interfere with regularity. Use the bathroom when you feel the urge and consider placing your feet on a small stool to make your position more comfortable.
- Know when to talk to a health care provider. Contact a health care provider if constipation does not improve with self-care. Seek care promptly if constipation occurs with rectal bleeding, blood in your stool, constant abdominal pain, vomiting, fever, an inability to pass gas or unintentional weight loss.
Our Expert Take
A lentil grain bowl topped with avocado and cooked vegetables, plus two green kiwis and water is a strong lunch choice for a post-lunch-poop because it addresses stool bulk, softness and overall fiber intake in one meal. The lentils, whole grains, vegetables, avocado and kiwis provide different types of fiber, while the water helps that fiber hold onto moisture.
Still, the benefit is more likely to come from consistent habits than from one especially fibrous meal. Remember to adjust the portions if you are not used to eating much fiber, keep drinking water throughout the day and pay attention to your body’s urge to go. If constipation persists or comes with pain, bleeding or other concerning symptoms, check in with a health care provider.
