**TL;DR:** A low-residue diet is the GLP-1 nausea-day reset: white rice, white bread, eggs, lean meat, dairy, smooth nut butters, and skinned/cooked vegetables and fruit. Avoid raw vegetables, beans, whole grains, nuts, seeds, and high-fat foods. Use it for 2–7 days during severe nausea or diarrhea, then transition back.

When GLP-1 nausea is at its worst — usually the first week of a dose increase, or after a particularly hard week — a temporary low-residue diet can be the reset that gets you back on track.

## What a "low-residue diet" actually is

Low-residue (sometimes called "low-fiber") is a temporary eating pattern that minimizes the undigested material moving through your digestive tract. It is the standard recommendation pre-colonoscopy, after some abdominal surgeries, and during severe IBD flares. It is also useful as a short-term reset during severe GLP-1 GI distress.

The principle: smaller residue → less stomach distension → less nausea → less risk of vomiting or worsening reflux.

## What to eat

**Proteins:**
- Eggs (any style except fried)
- Plain chicken or turkey breast (no skin)
- White fish (cod, tilapia)
- Tofu (firm, cooked)
- Greek yogurt (plain)
- Cottage cheese
- Smooth peanut butter (limit to 1–2 tbsp)
- Whey or casein protein powder

**Carbs:**
- White rice
- White bread (sourdough, regular)
- Plain pasta
- Crackers (saltines, ritz)
- Cream of wheat or grits
- Mashed white potato (no skin)

**Dairy:**
- Milk (1% or 2%)
- Plain yogurt
- Cottage cheese
- Mild cheeses (mozzarella, cheddar, ricotta)

**Vegetables (cooked, no skin or seeds):**
- Carrots, peeled and well-cooked
- Zucchini, peeled
- Spinach, well-cooked
- Squash, peeled and cooked
- Green beans, well-cooked

**Fruits:**
- Bananas (ripe)
- Applesauce (no skin)
- Canned peaches/pears (in juice, not syrup)
- Cantaloupe, honeydew (no seeds)
- Strained orange juice

**Liquids:**
- Water
- Broth
- Herbal tea (chamomile, ginger, peppermint)
- Electrolyte drinks
- Smoothies (made with smooth ingredients)

## What to avoid (temporarily)

- Whole grains (whole wheat bread, oats, brown rice, quinoa)
- Beans, lentils, legumes
- Raw vegetables (especially leafy)
- Cruciferous vegetables (broccoli, cauliflower, Brussels sprouts)
- Onions, garlic in volume
- Nuts and seeds
- Fruit with skins or seeds
- Dried fruit
- Tough meats (steak, jerky, pork)
- Fried foods
- Spicy foods
- Alcohol
- Carbonated beverages
- Coffee (for some patients — not all)

## A sample low-residue GLP-1 day

**Breakfast:** Cream of wheat with banana + 1 scoop protein powder mixed in (cooled) → 28 g protein

**Snack:** Greek yogurt + 1 tbsp smooth peanut butter → 18 g protein

**Lunch:** White rice + 4 oz baked chicken breast + ½ cup cooked carrots → 30 g protein

**Snack:** Cottage cheese + applesauce → 16 g protein

**Dinner:** Baked cod + mashed potato + cooked zucchini → 32 g protein

**Total: 124 g protein, ~1,300 cal.** Well-tolerated even on bad-stomach days.

## How long to stay on it

Low-residue eating is a short-term tool, not a long-term diet. It deprives you of fiber, which matters for gut health.

- **2–3 days:** Quick reset after a bad nausea episode
- **5–7 days:** During the worst of a dose-increase week
- **Beyond 7 days:** You should be transitioning back

## How to transition back

After the worst symptoms resolve:

**Days 1–2:** Add 1 cooked vegetable per day (carrots, zucchini)
**Days 3–4:** Add 1 fruit per day (bananas, melon)
**Days 5–7:** Reintroduce whole grain bread, oats
**Week 2:** Reintroduce small portions of beans, raw greens, broccoli
**Week 3:** Back to normal

If symptoms return as you reintroduce, hold at the previous step for a few more days.

## When low-residue is a red flag

Needing low-residue eating for more than 2 weeks at a time suggests:

- Your GLP-1 dose is too high for you (call your prescriber)
- You have an underlying GI issue (IBS, gastroparesis worsening, etc.)
- You should see a GI specialist

## Liquid-only days

For acute episodes — uncontrolled vomiting, severe diarrhea — a 24-hour liquid-only approach can let your gut rest:

- Water
- Broth (sodium-rich)
- Electrolyte drinks
- Plain tea (chamomile, ginger)
- Diluted juice
- Protein shake (if tolerated)

If you cannot keep liquids down for 24+ hours, that's an ER trip — you're at dehydration risk.

## Bottom line

Low-residue eating is the GLP-1 patient's tactical reset for severe nausea or diarrhea days. White rice, eggs, plain chicken, cooked vegetables without skin, ripe bananas. Use it for a few days, transition back deliberately. If you need it more than 2 weeks at a time, your dose is wrong for you — call your prescriber.
