Preparing for a colonoscopy can feel overwhelming, especially when food choices suddenly matter. A structured 1 week colonoscopy diet sheet helps your bowel clear properly and supports accurate test results. What you eat in the days before the procedure directly affects how successful the colonoscopy will be.
This article explains a complete 1 week colonoscopy diet sheet. You will learn what to eat each day, which foods to avoid, how to transition to liquids, and common mistakes to prevent.
Why a 1 Week Colonoscopy Diet Sheet Is Important
A colonoscopy allows your doctor to examine the lining of your colon for polyps, inflammation, or cancer. For clear visibility, the bowel must be free of stool and residue.
Following a 1 week colonoscopy diet sheet reduces fiber and undigested material. This improves bowel cleansing and lowers the chance of repeating the procedure.
Diet preparation works together with bowel prep medications.
How the 1 Week Colonoscopy Diet Sheet Works
The diet changes gradually over seven days.
You start by reducing fiber, then switch to low-residue foods, and finally move to clear liquids.
This step-by-step approach is easier on your digestion and improves compliance.
Days 7–5 Before Colonoscopy: Start Low-Fiber Eating
Goal of This Phase
The goal is to reduce stool bulk early.
Lower fiber intake helps your colon empty more efficiently later.
Foods You Can Eat
Choose refined grains like white bread, white rice, and plain pasta.
Eat eggs, chicken, fish, and tofu for protein.
Include dairy such as milk, yogurt, and cheese if tolerated.
Foods to Avoid
Avoid whole grains, oats, brown rice, and bran cereals.
Skip raw vegetables, leafy greens, and salads.
Do not eat nuts, seeds, or legumes.
Days 4–3 Before Colonoscopy: Low-Residue Diet
Why Residue Matters
Residue refers to undigested food left in the colon.
A low-residue phase is a core part of the 1 week colonoscopy diet sheet.
Allowed Foods
Eat white bread, pancakes, and plain crackers.
Choose well-cooked vegetables without skin or seeds.
Mashed potatoes without peel are usually safe.
Foods to Stop Completely
Stop eating fruits with skin or seeds.
Avoid corn, peas, beans, and lentils.
Do not consume red meat or fried foods.
Day 2 Before Colonoscopy: Transition Day
This day prepares your body for liquid-only intake.
Your meals should be smaller and very easy to digest.
What to Eat
Stick to plain eggs, yogurt, white toast, and broth.
Avoid heavy meals or late-night eating.
Hydration Focus
Begin increasing fluid intake.
Good hydration improves bowel prep effectiveness.
Day 1 Before Colonoscopy: Clear Liquid Diet
The day before the procedure is critical.
This phase of the 1 week colonoscopy diet sheet allows only clear liquids.
Approved Clear Liquids
Drink water, clear broth, apple juice, and white grape juice.
Sports drinks help maintain electrolytes.
Plain tea or coffee without milk is allowed.
Gelatin and Popsicles
Plain gelatin and ice pops are allowed.
Avoid red, purple, or blue colors.
What to Avoid Completely
Do not eat solid food.
Avoid alcohol, dairy, and smoothies.
Day of Colonoscopy: Fasting Period
You must stop drinking liquids several hours before the test.
Follow your doctor’s exact cutoff time.
This prevents aspiration during sedation.

Common Mistakes to Avoid
Many people accidentally eat seeds or high-fiber foods.
Colored drinks are another frequent mistake.
Not drinking enough fluids can worsen prep discomfort.
Special Considerations for Medical Conditions
If you have diabetes, low blood sugar risk must be managed.
Kidney or heart disease may require fluid adjustments.
Always discuss changes with your healthcare provider.
Medications and Supplements to Review
Iron supplements often need to be stopped.
Fiber supplements should be avoided during the week.
Ask your doctor about blood thinners and diabetes medications.
Managing Hunger and Fatigue
Hunger is common during the clear liquid day.
Warm broth can improve satiety.
Spacing fluids throughout the day helps energy levels.
After the Colonoscopy: Returning to Normal Eating
Most people can eat within hours after the procedure.
Start with light foods and advance gradually.
Your doctor may give specific instructions based on findings.
Emotional Reassurance
Diet changes can feel restrictive and frustrating.
Remember that the 1 week colonoscopy diet sheet is temporary.
Proper preparation protects your digestive health and future care.
Final Thoughts
