Easy GLP-1 Breakfast: Peanut Butter Overnight Oats

If you’re on a GLP-1 medication, breakfast can be one of the hardest meals to figure out—especially when you need something high-protein, easy to eat, and not too heavy.

These peanut butter overnight oats fulfill GLP-1 meal requirements: high protein, high fiber, and light enough to eat when you don’t feel like eating. It’s perfect for easy meal prep—and you probably already have most of the ingredients in your cupboard.

I make this for breakfast regularly in the summer. Like most overnight oat recipes, it’s easy to make—but this one is filling, high in protein, and still light enough to eat when food doesn’t sound appealing. Plus, it’s cold (who wants to cook in the summer?) and lightly sweet from the banana.

Why These Overnight Oats Work on a GLP-1 Diet

  • High protein to help meet daily goals
  • Easy-to-eat portions when appetite is low
  • Not overly heavy or hard to digest
  • Combines protein and fiber for satiety
  • Perfect for simple meal prep (no cooking)

Practical, high-protein breakfasts like this make it much easier to stay consistent. It tastes good, it’s simple, and it works—even when you’re not hungry but still need to eat.

The hardest thing about this breakfast is slicing the banana.   

Ingredients

  2. Stir in powdered peanut butter and chia seeds
  3. Add oats and stir to combine
  4. Cover and refrigerate for at least 4 hours (overnight gives the best texture)
  5. Top with sliced banana before serving
  6. Add 1-2 Tbsp honey if desired

What Makes This High-Protein

  • Non-fat Vanilla Greek yogurt has 12-17g protein

Together, these ingredients create a simple, high-protein breakfast that’s easy to tolerate on a GLP-1 diet.

High-protein breakfasts like these overnight oats don’t get much simpler. With 28g of protein in the oats alone, plus a banana and added protein in your coffee, this breakfast can easily reach around 35g of protein for about 550 calories.
