# 10 breakfasts under 400 calories, ready in 15 minutes

By the GO AI Team · August 21, 2026

> **TL;DR:** A breakfast that holds until lunch is built on **protein**, not cereal. Every option below leads with eggs, Greek yoghurt, skyr, cottage cheese or a protein base, adds fruit or vegetables for volume, keeps fat measured. The three quiet inflators: the **oil**, the **nut butter**, and the **drink you didn't count**.

**About the numbers.** Estimates for a typical portion from standard reference values; yours depend on your portions. Photograph the plate for your own figures. General information for adults, not medical or dietary advice.

## Why protein specifically

Traditional breakfast is almost entirely carbohydrate — cereal, toast, pastries, juice. It digests fast and leaves nothing behind, which is why 300 calories of cereal has you rummaging by ten and 300 calories of yoghurt doesn't.

The fix isn't more calories; it's a different composition of the same ones.

## The ten

1. **Greek yoghurt bowl** — berries, a spoon of oats, a few nuts. Two minutes. Count the nuts.
2. **Two-egg scramble with feta and spinach** — wilt spinach first, eggs low and slow, feta off the heat. ~25g protein.
3. **Overnight oats with berries** — made the night before, which is the feature.
4. **Cottage cheese on rye with tomato** — deeply unfashionable, extremely efficient.
5. **Smoked salmon on a bagel thin** — capers, red onion, lemon. Tastes like a treat.
6. **Protein smoothie** — blend with ice for volume; same ingredients feel like twice as much.
7. **Shakshuka for one** — twelve minutes, mostly unattended, base keeps for days.
8. **Egg-white and mushroom omelette** — one whole egg for flavour, mushrooms browned properly first.
9. **Skyr with apple and cinnamon** — leaner than Greek yoghurt, tastes like dessert.
10. **Avocado and egg on sourdough** — half an avocado, one slice, one egg. Fits fine. The *whole* avocado doesn't.

## The three quiet inflators

- **Oil in the pan** — eggs need almost none. A glug beats the eggs.
- **Nut butter** — a "spoonful" is routinely two, and it's dense enough to matter.
- **The drink** — a large flavoured coffee can outweigh any breakfast here. Not a reason to skip it; a reason to know.

## Making mornings survivable

Pick **three** and rotate. Breakfast is decided at your least decisive, so removing the decision beats variety. Prep the night before whenever possible — that's what makes a plan survive a real morning.

Mornings genuinely don't work? Skipping is legitimate — [the day's total is what matters](https://goaichat.app/blog/calorie-deficit-explained). Just notice honestly whether it means eating less or arriving at lunch ravenous.
