Breakfast cereals have long been cast aside as an unhealthy option for ‘the most important meal of the day.’ Traditional brands are carb-heavy, contain high amounts of sugar, and offer only a small protein pay-off.

Oats – topped with banana and a dollop of peanut butter – have become the functional athlete’s favourite.

But since 81% of Brits still want cereal for breakfast, more brands are producing special ‘protein’ options to knock the oat from its throne.

Some of these offer a higher protein content than even chicken breasts, and several throw it back to some favourite flavours of old.

MF Best Buy:
Surreal

£24 (4 boxes) / eatsurreal.co.uk

Surreal’s bright packaging catches the eye, and what’s inside the box is every bit as appealing. Its creators sell it as ‘the cereal you loved growing up, made nutritionally relevant to the adult you’ve become.’

And based on its nutritional merits, it lives up to the billing. With 42g of protein in every 100g, Surreal has the second-highest protein content of all the cereals we tried, and the O-shaped pieces have a nice crunch and flavour to them.

Myprotein Protein Granola

£5.49 (320g pack) / myprotein.com

Cereal purists may argue granola shouldn’t make the list, but we’re happy to face their wrath if it means featuring this impressive protein-packed option.

We found no difference in taste between Myprotein’s granola and any up-market brand – except this has twice as much protein.

Weetabix Protein

£2.50 (24-pack) / groceries.asda.com

A perfect example of a household brand’s successful attempt to create a more balanced breakfast option, these loaded bix provide 19g of protein per 100g.

Like regular Weetabix, their taste all depends on what you decide to put on top – we threw on sliced banana and a drizzle of honey.

Grandma Crunch

£26.48 (4 boxes) / grandmacrunch.co.uk

High-protein, low-carb and plant-based, Grandma Crunch tastes OK and the namesake crunch is evident, but the numbers are the really impressive factors.

Per serving there’s 15g protein, just 111kcals and a mere 0.4g sugar.

Super Zeros

£13.99 (2 boxes) / super-zeros.com

We dived into Super Zeros’ Apple and Cinnamon flavour first – which wasn’t the best decision. Although the mini balls held a nice crunch, the taste is on the sickly side.

Happily, the cocoa flavour provided redemption, and there’s a competitive 10g protein per 32g serving (but you’re doubling that, let’s be honest).

Holland & Barrett High Protein Muesli

£2.59 (500g pack) / hollandandbarrett.com

H&B’s high-protein muesli is one of the tastiest options in this list.

The protein content (21g per 100g) isn’t table-topping, but the nutty taste and generally healthy credentials make it a solid bet for anyone looking for to boost their breakfast.

Special K Protein Nuts, Clusters, and Seeds

£2.99 (330g pack) / groceries.asda.com

This is a pleasant enough mix of high-fibre grains (rice, wholewheat and barley), with protein-rich linseeds and sunflower seeds.

The fibre will keep you fuller for longer, but the 5.2g protein per serving is nothing to write home about (which, admittedly, we’ve just done).
