If you’re trying to lose weight but you still want cereal for breakfast, the goal is simple: pick one that keeps you full so you’re not hungry again an hour later.
What makes a cereal good for weight loss (my criteria)
I keep it simple. For weight loss I look for cereals that are:
- Higher in protein (or easy to add protein with Greek yoghurt/Skyr/quark)
- Higher in fibre
- Not too high in sugar
Now let’s get to the cereals.
The Best Cereals for Weight Loss
Click on any cereal below to jump to the details and see why it made the list.
- Protein oats (no added sugar)
- Shredded Wheat (plain biscuits)
- Grape-Nuts Original
- Wheat biscuits (Weetabix / Weet-Bix style)
- Weetabix Protein
- Plain porridge oats (rolled/jumbo oats)
- Wheat Chex (US only)
Runner-ups (still worth considering)
These can still work, but they’re higher in sugar, so portion size matters more (and I’d keep toppings simple):
- Kellogg’s All-Bran Fibre Plus (UK)
- Kellogg’s Bran Flakes (UK)
- Shreddies Original (UK)
1. Protein oats (no added sugar)
This is one of my favourite options because it’s so simple. It’s basically oats with some extra protein added in some cases. No added sugar.
Examples + key nutrition
Quaker Oat So Simple Protein Original (UK) — 8.1g protein, 2.7g fibre (per sachet, 37.7g)
Bob’s Red Mill Protein Oats (US) — 10g protein, 6g fibre (per 1/3 cup serving – 48g)
How I’d eat it
Add fruit for natural sweetness (berries, banana, grated apple). Optional: a small handful of nuts or seeds for healthy fats and extra staying power.
Worth knowing
Quaker’s higher protein comes from added soy protein. Bob’s is just oats.
2. Shredded Wheat (plain biscuits)
This is another one I really like because it’s properly simple. The plain versions are basically 100% whole grain wheat with no added sugar, which is hard to beat for a boxed cereal. For weight loss, it works best when you treat it like a solid base and add natural sweetness (fruit) rather than sugar or syrup.
Examples + key nutrition
Nestlé Shredded Wheat Original (UK) — 5.5g protein, 6.3g fibre (per 2 biscuits / 45g)
Barbara’s Shredded Wheat (US) — 6g protein, 7g fibre (per 2 biscuits / 51g), BHT free
If you can’t find those exact ones, supermarket own-brand plain shredded wheat can be just as good. Just check the ingredients and aim for something that’s basically “whole grain wheat” and nothing else.
3. Grape-Nuts Original
This is a great one to know about because it’s easy to find in the US, and you can also buy it in the UK (Tesco sells it).
It has no added sugar, and it’s also fortified, especially high in iron and folic acid.
Key nutrition (per 1/2 cup, 58g): 6g protein, 7g fibre.
One thing to keep in mind is that it’s quite a heavy cereal for its volume, so portion control matters. Weigh it once and you’ll instantly see what a normal serving looks like.
Because it’s quite heavy for its volume, portion control matters. Weigh it once and you’ll quickly get a feel for what a normal serving looks like.
Best way to eat it: since it has no added sugar, sweeten it with fruit (berries or banana) rather than honey or syrup.
4. Wheat biscuits (Weetabix / Weet-Bix style)
This is one of the most practical choices if you want something you can buy almost anywhere. Wheat biscuits are widely available internationally, they are fairly low in sugar, and they are easy to make more filling with the right toppings.
Examples + key nutrition
Weetabix Original (UK/EU and many other countries). A typical portion is 2 biscuits (37.5g) which gives you roughly 4.5g protein and 3.8g fibre. Per 100g it’s about 12g protein, 10g fibre, and 4g sugars.
Weet-Bix is the Australian/NZ version and it’s very similar. You will also find supermarket own-brand wheat biscuits in plenty of countries.
Because they’re only mildly sweet, I’d add fruit for natural sweetness (berries, banana, grated apple). If weight loss is your goal, I’d skip syrup and honey because they add extra calories fast.
5. Weetabix Protein
If you like Weetabix but you want something with a more noticeable protein boost, this is a solid mainstream option. It keeps sugar pretty sensible for what it is, and it’s also fortified (including vitamins and iron).
A typical portion is 2 biscuits (40g), which gives you about 7.6g protein and 4g fibre. Sugar-wise, it’s roughly 1.9g per 2 biscuits, which is about half a teaspoon.
Availability: It’s mainly a UK supermarket cereal, but you can sometimes find it in other countries through import shops or online (including Amazon). In the US, it’s not as common in regular supermarkets, but it does show up online from time to time too.
6. Plain porridge oats (rolled or jumbo oats)
Plain porridge oats are one of the best cereals for weight loss because they’re simple, cheap, and easy to find almost anywhere. They also have no added sugar, so you’re in control of how sweet (or not sweet) your breakfast is.
The only downside is that plain oats can feel a bit “softer” and less filling than protein oats for some people, especially if you keep the portion small (for example, 40g dry oats is roughly 4.4g protein and 3.6g fibre).
The fix is simple. Build it up with a bit of protein (milk, Greek yoghurt, Skyr, quark, or whey) and add fibre with fruit or a spoon of chia or ground flax.
7. Wheat Chex (US only)
If you’re in the US and you want a crunchy cereal you can grab in a normal supermarket, Wheat Chex is one of the better options. It’s also fairly high in fibre for a crunchy cereal, and it’s fortified.
Per serving (1 cup, 59g): 6g protein, 8g fibre, 6g added sugar (about 1.5 teaspoons).
It’s at the bottom of this list because it’s more processed than the simpler wheat cereals above. The ingredient list is longer and includes added sugar and molasses, plus a long list of added vitamins and minerals because it’s fortified.
Make your cereal swap count
Choosing a better cereal is a smart first move for weight loss, especially if cereal is your everyday breakfast. If your new breakfast keeps you full, you’re far less likely to snack mid-morning or end up craving something sweet before lunch. That alone can make your day feel easier.
But it’s worth saying out loud. You won’t lose weight from only switching to a better cereal if the rest of the day is still packed with sugary snacks, big takeaway meals, or random grazing. Breakfast can set the tone, but weight loss comes from the overall pattern.
What I’d do is keep it simple and go step by step:
- Step 1: Fix breakfast first. Pick one cereal from this list and stick with it for a week.
- Step 2: Keep the sweetness natural. Use fruit, not honey, syrup or sugar.
- Step 3: Watch the “extras”. It’s usually the toppings and the portion size that turn cereal into a calorie bomb.
- Step 4: Once breakfast feels easy, look at your next “weak spot” (for many people it’s afternoon snacking).
If you like cereal every day, choosing the right one is absolutely worth doing. Just treat it as the first domino, not the whole plan.
