What People Get Wrong About Breakfast
Breakfast: what people commonly get wrong, set against what published UK guidance says.
Muscle protein synthesis responds to each meal rather than the daily total, so a carbohydrate-only breakfast wastes part of what you eat later.
Key takeaways
- Useful breakfast protein target: 20-30g
- Greek yoghurt, 200g: about 20g protein
- Most useful single change: Put 20 to 30g of protein into breakfast.
- Commonest mistake: Flavoured yoghurts, which can carry as much sugar as a pudding.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
What the guidance actually says
These are the numbers the corrections below are measured against.
| Measure | Figure |
|---|---|
| Useful breakfast protein target | 20-30g |
| Greek yoghurt, 200g | about 20g protein |
| Two eggs | about 12g protein |
| Cottage cheese, 200g | about 24g protein |
| Overnight oats with milk and yoghurt | about 20g protein |
Where people go wrong
These are widely believed and not supported by the guidance above.
- Flavoured yoghurts, which can carry as much sugar as a pudding
- Assuming a protein bar is equivalent without checking the sugar
- Skipping breakfast to save calories and arriving at lunch ravenous
What to do instead
- Put 20 to 30g of protein into breakfast
- Prepare overnight options the evening before
- Buy plain yoghurt and add your own fruit
- Use frozen berries, which are cheaper and nutritionally equivalent
The part that is genuinely uncertain
Guidance changes, and it changes because evidence does. The figures above reflect current UK guidance from the bodies named at the foot of this page; where those bodies revise their position, theirs is the account to follow rather than this one.

When to speak to a doctor
Speak to a GP or dietitian before raising protein substantially if you have chronic kidney disease. If you have an egg or dairy allergy or coeliac disease, adapt rather than assume these are safe. If thinking about food is causing distress, contact your GP or the Beat helpline on 0808 801 0677.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
