I write about food for a living, so when a friend handed me a chocolate muffin and told me it was 48 calories, my first reaction was to laugh at her.
Forty-eight calories is about half a banana. It is not a chocolate muffin. A real one — chunks crowning the top, a crumb dense enough to pull apart with your fingers — sits somewhere between 380 and 500. Anyone telling you otherwise is usually selling a sad protein puck with cocoa powder in it.
So I read the packet. Then I read it again. Then I emailed the company.
The brand is WiO SmartFoods, a small American food-science company that ships direct from a bakery in the US. The label says 48 calories absorbed and 9 grams of protein. The ingredient list reads like something you would actually bake: wheat flour, eggs, real butter, real cocoa, chocolate chunks. No sugar-alcohol situation. No grim fibre blend doing the structural work.
I ordered a four-pack. I ate one cold, straight out of the box. I ate one warmed for fifteen seconds, until a chunk on top went glossy. I ate the third the next morning with black coffee, which is the natural habitat of a chocolate muffin.
Here is the part I was not prepared for. It is, unmistakably, a chocolate muffin.
What's in the box
So how does the arithmetic work?
I asked. The company's explanation is that it bakes a plant-derived molecule called modified cyclodextrin into the recipe — a compound studied since the 1980s, originally for pharmaceutical use, where its job is carrying other molecules around.
Picture a sugar molecule folded into a hollow ring, open at both ends and empty in the middle.
When a fat or carbohydrate molecule meets one in the gut, it slides into the ring and lodges there.
Digestive enzymes cannot reach what is inside the ring, so the pair passes through unabsorbed.
So the muffin contains roughly 400 calories of ingredients. Your mouth, your gut and the entire social experience of eating it get the full muffin. What your body ends up absorbing, according to WiO, is about 48 of those calories — and that absorbed figure is what the company prints on the label.
Whose claim is whose
Worth separating out, because I had to do it myself. Cyclodextrins are real and well documented — ring-shaped starch derivatives used for decades in food and pharmacy, with genuine research behind the encapsulation mechanism.
The 48-calorie figure, the 400-calorie ingredient total and the labelling approach are WiO's own, based on its reading of US guidance for non-digestible ingredients. I have not seen independent verification of the absorbed-calorie number, and I am not in a position to test it. Take it as the manufacturer's claim rather than a settled fact.
I am not easily impressed by diet food, and this does not read as diet food. It reads as a chocolate muffin that happens to be physiologically lazy.
The texture is the part nobody warns you about
You brace for compression. Dryness. That chalky quality of a protein bar doing an impression of cake. Instead the crumb tears. The crown is crisp where the chunks have melted down into it. There is butter on your fingers afterwards.
I gave one to my sister, who bakes and is constitutionally suspicious of anything marketed at her. She said two things, in this order: “this isn't a protein muffin,” and then, “wait, what.”
What I would tell a friend
- Order the four-pack first. You will want a second to confirm the first was not a fluke, and a third for the next morning. Four is about right for deciding.
- Have the first one warmed. The cold version is good. The warmed one is the one I photographed for the group chat.
- They freeze well. They ship fresh from the bakery in cool packaging and turn up within the week. If you order more than a four-pack, the freezer is the answer.
I am going to keep buying these. Not because I am on a diet, but because I had quietly decided somewhere along the way that I was a person who no longer got to have a real chocolate muffin in the morning. It turns out I was wrong about that, which is a better outcome than most things I test.

Questions I had first
Does it actually taste like a chocolate muffin?
That was the surprise. The crumb tears instead of compressing, the crown is crisp where the chunks melted into it, and there is butter on your fingers afterwards. It does not have the chalk of a protein bar pretending to be cake.
How can a muffin be 48 calories?
The brand's account is that a modified cyclodextrin baked into the recipe binds some fat and carbohydrate in the gut, so it passes through unabsorbed. The muffin contains roughly 400 calories of ingredients; WiO states about 48 are absorbed, and prints that figure on the label. As above — that absorbed-calorie framing is the company's, not an independently verified measurement.
What is modified cyclodextrin?
A ring-shaped molecule derived from starch, studied since the 1980s and used for decades as a carrier in food and pharmaceutical applications. The useful property is the hollow centre, which can trap other molecules inside it.
Are there sugar alcohols or a fibre blend?
Not according to the ingredient list, which reads as wheat flour, eggs, real butter, cocoa and chocolate chunks. That is a large part of why the texture survives. If you react badly to sugar alcohols, read the current packaging anyway — recipes change.
Will it help me lose weight?
Nobody can promise you that and this article is not going to. What it is, is a lower-absorbed-calorie version of something people normally cut out entirely. Whether that helps depends on everything else you eat, and it is not a substitute for advice from a doctor or dietitian if you are managing your weight for medical reasons.
How do they arrive?
Direct from the bakery in cool packaging, typically within the week. They freeze well. Orders, shipping and returns are handled by WiO SmartFoods — Nutrition Goods has no access to orders and cannot help with them.
