Your stomach may hold the quickest route to feeling better. Gut health influences digestion, energy, mood and immunity. Dr. Katherine Freeman, a gastroenterologist with Catholic Health tied to St. Francis Hospital and Heart Center, lays out a gentle, seven-day reset that avoids extreme fasting or juice cleanses and focuses on practical food and lifestyle swaps you can keep using.
Begin with a check-in and a cleaner plate
Before starting any nutrition program, talk to your primary care doctor, gastroenterologist or a registered dietitian to make sure it fits your needs.

On the first day, prioritize removing obvious gut irritants and leaning into simple, nourishing foods.
- Cut out: refined sugars, artificial sweeteners, heavily processed snacks, and regular servings of red meat.
- Choose instead: grilled poultry or fish, steamed or roasted vegetables, whole grains and plenty of water.
- Season smartly: ginger, turmeric and peppermint can support digestion and help reduce inflammation.
These changes aim to lower chronic, low-level inflammation and calm the digestive tract.
Hydration and calming teas to soothe your GI tract
Day two centers on fluids. Aim for roughly 64 ounces of water across the day. Hydration helps keep digestion moving and reduces discomfort.
Integrate gentle teas that support gut function.
- Green tea for antioxidants and mild anti-inflammatory benefits.
- Peppermint or ginger tea for digestive comfort after meals.
Introduce live cultures and nourishing fibers on days three and four
Midweek, focus on rebuilding the microbial balance with prebiotics and probiotics.
These feed and populate the gut microbiome, strengthen the intestinal barrier and can help lower gut inflammation.
- Probiotics: plain yogurt, kefir, fermented vegetables such as sauerkraut or kimchi.
- Prebiotics: garlic, onions, asparagus, leeks and bananas.
Adding these foods supports immune signaling between the gut and brain and may ease anxiety tied to gut dysfunction.
Make fiber and movement a daily habit
Day five highlights fiber and activity. Fiber stabilizes energy and feeds healthy bacteria.
- Fiber-rich picks: oats, brown rice, whole grains, chia seeds, lentils and leafy greens.
- Aim for at least 30 minutes of moderate activity, such as brisk walking or using an elliptical.
Moving helps regularity. Combined with hydration and whole grains, it often reduces bloating and improves bowel patterns.
Build sleep, stress reduction and routine into your plan
On day six, focus on reinforcing habits that support long-term gut balance.
- Shift dinner earlier to give the body time to digest before sleep.
- Limit alcohol and late-night snacking.
- Prioritize 7–8 hours of sleep to support circadian rhythms and digestive health.
- Turn off screens before bed and spend time with family or friends to lower stress.
Emotional wellbeing matters. Stress and social isolation can worsen GI symptoms just as much as diet.
Plan for sustainability and medical follow-up
Day seven is about consolidating gains and planning for longer-term change. Reflect on what felt helpful and what was hard to maintain.
Questions to guide you:
- Which meals left you energized and which caused bloating?
- How did sleep, hydration and movement affect your digestion?
- What small routines can you repeat weekly?
Check in with your gastroenterologist to review outcomes and tailor adjustments. This is intended to be a springboard, not a one-off cure.
