6 High Protein Overnight Oats Under 400 Calories

Your morning starts fast, coffee hasn’t kicked in, and breakfast either needs to be ready now or it’s probably getting skipped.

Sound familiar?

Overnight oats work best when the jar has enough protein, enough texture, and enough sweetness to feel planned instead of like diet food. These jars are built for rushed mornings, weight loss weeks, sweet cravings, and busy workdays where breakfast needs to be one less decision.

Use the calorie target as a guardrail, then adjust toppings based on hunger and your body’s own feedback.

Before we get to Meal #3...

My clients frequently ask me “What are the best sources of protein?”

And while they love the protein & grocery list calculators... just knowing the best sources of protein to anchor meals around (and why) is incredible helpful.

Because knowledge is power.

So in an effort to help you, I created a video on the Top 10 Sources of Protein (and a few to avoid).

I hope you find it helpful!
