Post-Injection Day Meal Guide

The 24-48 hours after your GLP-1 injection are when nausea, bloating, and reduced appetite are at their peak, especially during dose escalation. This guide gives you a gentle eating timeline to get through the toughest days while still meeting basic nutritional needs.

Injection Day Timeline

Before injection

Eat a light meal 1-2 hours before injecting.

Good options: plain toast with peanut butter, small bowl of oatmeal, scrambled egg on toast. Avoid large or heavy meals.

0-2 hours after

Sip ginger tea or plain water. Do not force food.

If nauseous, try ginger chews or candies. Small ice chips can help. Peppermint tea is another option.

2-4 hours after

If tolerated, try clear bone broth (warm, not hot) or miso soup.

Sip slowly over 15-20 minutes. Bone broth provides protein (10g/cup) and electrolytes without taxing digestion.

4-6 hours after

Small portion of bland protein if appetite allows.

Options: 2-3 oz plain chicken breast, 2 scrambled eggs, 1/2 cup cottage cheese, 4 oz plain Greek yogurt. Eat slowly, stop at the first sign of fullness.

6-8 hours after

Light dinner if tolerated. Keep portions very small.

Options: small bowl of chicken and rice soup, 3 oz baked fish with steamed vegetables, half a turkey sandwich on white bread. Avoid anything fried, spicy, or high-fat.

Evening

Optional light snack before bed if hungry.

Options: string cheese, small apple with peanut butter, handful of crackers. Continue sipping water or ginger tea.

Day After Injection

Morning

Start with ginger tea or warm lemon water. Then try a gentle breakfast.

Options: plain oatmeal with banana, toast with a thin layer of peanut butter, Greek yogurt (plain), scrambled eggs.

Midday

Nausea usually begins to improve. Increase protein intake.

Options: chicken breast with rice, tuna on crackers, cottage cheese with fruit. Aim for 25-30g protein at this meal.

Afternoon

Continue grazing with small, protein-rich snacks.

Options: hard-boiled egg, turkey roll-ups, protein smoothie (gentle: whey + banana + almond milk).

Evening

Return to a more normal dinner, but keep portions moderate.

Options: baked salmon with vegetables, chicken stir-fry with rice, turkey chili (small bowl). By day 2, most patients feel significantly better.

Hydration Protocol

Sip, do not gulp. Small sips of water throughout the day are better than large amounts at once.
Add electrolytes to at least one glass of water per day (especially if vomiting or diarrhea occurred).
Avoid drinking during meals. Wait 30 minutes before and after eating to drink water.
Target 64+ oz of fluids daily. Herbal tea, broth, and flavored water all count.
If you cannot keep water down for more than 4-6 hours, contact your provider.

When to Call Your Provider Contact your healthcare provider if: nausea or vomiting persists beyond 48 hours, you cannot keep any food or liquid down for 6+ hours, you experience severe abdominal pain, you notice signs of dehydration (dark urine, dizziness, rapid heartbeat), or if symptoms are significantly worse than previous injection days.
