On Ozempic or Mounjaro, lean white fish like cod is one of the easiest proteins to digest — ideal when GLP-1 side effects like nausea and delayed gastric emptying are at their peak. Steaming preserves nutrients and requires zero added fat, keeping calories minimal while delivering 30g of protein per serving. Avoid fried fish, fish sticks, and tartar sauce loaded with sugar and fat that can upset your stomach on GLP-1. Steamed cod with wilted spinach is clean, simple, and effective.
Fill a pot with 2 inches of water and bring to a boil.
Place cod in a steamer basket, season with salt and white pepper.
Steam 8–10 minutes until fish is opaque and flakes easily.
Heat olive oil in a pan over medium heat.
Add minced garlic and sauté 30 seconds.
Add spinach and toss until just wilted, about 2 minutes.
Plate spinach first, then place steamed cod on top.
Squeeze fresh lemon juice over fish and serve immediately.
