Calories in a Greggs Yum Yum: 310 kcal [62 Min of Walking]
One Yum Yum weighs 78.2 g and comes to 310 calories. The two-pack is 619. The calories in a Greggs Yum Yum sit well above anything else that looks like it on the counter, and the reason is that it is not what most people think it is.
You'd need to walk about 62 minutes to burn the 310 calories in one 78.2 g twist.

Verified nutrition data

*RI% = one Yum Yum as a share of an adult's daily reference intake, based on 2,000 kcal.
Three hundred and ten calories is a sixth of an adult's day for something eaten in about ninety seconds. The saturates row is the one that deserves a second look: 8.6 g out of a 20 g daily reference, from one item, before breakfast has finished.
Salt at 0.77 g is higher than a sweet thing has any business being. That is dough salt, and it puts a Yum Yum on level terms with a slice of bread.
It is not a doughnut
Everything about the placement says doughnut. It is glazed, it is sweet, it lives in the same window, and it costs about the same. The recipe says otherwise.
A Yum Yum is laminated pastry: dough folded around layers of fat, rolled out, twisted, proved and fried, then glazed. Doughnut dough is enriched bread dough, mixed once and shaped once. Lamination means solid fat is built into the structure before anything reaches the fryer, so the finished item starts fatty and then picks up more.
The per-100 g figures put a number on that difference. A Yum Yum is 396 kcal per 100 g. The glazed ring doughnut on the same counter is 346, and the jam doughnut 311. Gram for gram the twist carries 50 more calories than the ring and 85 more than the filled doughnut, and it is the densest sweet item Greggs sells in that window.
That is the whole story of this page in one paragraph. Same shelf, different food, and the difference is fifty to eighty-five calories in every hundred grams.
One, two, and the hot ones
| Item | Weight | Calories | Sugars | Saturates | Salt |
|---|---|---|---|---|---|
| Yum Yum | 78.2 g | 310 kcal | 16 g | 8.6 g | 0.77 g |
| Yum Yums, 2 pack | 156.4 g | 619 kcal | 33 g | 17 g | 1.5 g |
| Hot Yum Yums | 156.4 g | 619 kcal | 33 g | 17 g | 1.5 g |
The hot ones are the same product warmed through: same weight, same 396 kcal per 100 g, same 619 for the pack. Heat changes the texture and nothing on the label. If you have been assuming the hot version is a different or larger item, it is not.
There is no single-item hot option. Both multi-buy formats hold two twists, so a hot Yum Yum bought on its own is really half a 619 kcal purchase.
Why the two pack is the trap
Six hundred and nineteen calories is a meal. Not a snack that got out of hand, a meal, and one with almost no protein in it: 7.4 g across the pair.
Put the pack next to the savoury counter and the scale of it lands properly. A sausage roll is 348 calories. A glazed ring doughnut is 201. Buy both, eat both, and you are on 549, which is still 70 calories short of the two-pack of Yum Yums.
The rest of the pack follows the same multiplier. Thirty-three grams of sugar is over a third of the 90 g daily reference. Seventeen grams of saturates is 85% of the day's 20 g. One and a half grams of salt is a quarter of the 6 g maximum the NHS works from, out of a bag of sweet pastry.
None of that makes the two-pack a bad purchase if two people are eating. It makes it a bad purchase for one, which is how most of them get eaten.
The Greggs counter, ranked
| Item | Weight | Calories | Per 100 g |
|---|---|---|---|
| Glazed Ring Doughnut | 58 g | 201 kcal | 346 |
| Jam Doughnut | 76 g | 236 kcal | 311 |
| Yum Yum | 78.2 g | 310 kcal | 396 |
| Sausage Roll | 103 g | 348 kcal | 338 |
| Belgian Bun | 122.5 g | 371 kcal | 303 |
The two columns disagree, and the disagreement is the useful part.
By the item, the Yum Yum is mid-table: cheaper than a sausage roll and a fair way below a Belgian Bun. By weight it tops the list outright, ahead of everything including the pastry-wrapped meat. The Belgian Bun is the mirror image, highest per item at 371 and lowest per 100 g at 303, because it is a big soft bun with icing and a cherry rather than a dense fried twist.
So the Yum Yum is the item that gives you the least food for the calories. That is worth knowing when a Belgian Bun sitting beside it, 61 calories more, is 44 g heavier.
Where the saturates land
Sugar gets the attention on a sweet pastry and it is not the number that separates this one. Sixteen grams in a twist is 18% of the daily reference, which is ordinary for the category.
The saturated fat is not ordinary. At 8.6 g per twist it uses 43% of an adult's 20 g reference, and that lands squarely on the lamination. The fat sheeted between the layers is what makes the pastry flaky, so it is not a shortcut a baker can leave out. The NHS guidance on fats treats pastry as one of the standard saturated fat sources for exactly this reason.
Set that against the jam doughnut two trays over and the contrast is sharp. Same counter, similar weight, and a filled doughnut is not built on folded fat at all.
What to buy instead
Our take: for near enough the same weight of food, take the jam doughnut. It is 76 g against 78.2 g, so the bite is the same size, and it is 236 calories against 310. That is 74 calories saved, a 24% cut, for a swap most people would not notice by the second mouthful. If it is the glaze you are after rather than the filling, the glazed ring at 201 does the job for two thirds of the price in calories.
Buy the Yum Yum when it is the thing you actually want. It is a good pastry and there is no lighter version of it, so trading down to a joyless substitute is the wrong move. Buy the single, not the two-pack, and treat it as the sweet part of a meal rather than something on top of one.
If you are picking from a different window altogether, a scone, a hot cross bun and a croissant all sit in more moderate territory, and a flapjack is the one to avoid if calories are the deciding factor. For the filled doughnut numbers in full, the jam doughnut page has them.

Greggs Yum Yum FAQs
How many calories in a Greggs Yum Yum?
310 kcal for one 78.2 g twist, which works out at 396 kcal per 100 g. It carries 17 g of fat, 8.6 g of it saturates, 16 g of sugar and 0.77 g of salt. That is 16% of an adult's daily calorie reference and 43% of the saturated fat reference from a single item.
How many calories in a Yum Yum 2 pack?
619 kcal for 156.4 g, with 33 g of sugar, 17 g of saturates and 1.5 g of salt. That is more than a sausage roll and a glazed ring doughnut eaten together, which come to 549. The pack holds a third of a day's calories and 85% of the daily saturated fat reference.
How many calories in Hot Yum Yums?
619 kcal, the same as the cold two-pack. Both are 156.4 g at 396 kcal per 100 g, so warming them changes the texture and nothing in the nutrition table. There is no single-item hot format, which means a hot Yum Yum is half of a 619 kcal purchase.
Is a Yum Yum a doughnut?
No. A Yum Yum is laminated pastry, folded around layers of fat then twisted, fried and glazed, while a doughnut is enriched bread dough. The difference shows up in the numbers: 396 kcal per 100 g for the twist against 346 for a glazed ring and 311 for a jam doughnut on the same counter.
Yum Yum or a Greggs doughnut?
The doughnut, on both counts. A jam doughnut is 236 kcal for 76 g and a glazed ring 201 kcal for 58 g, against 310 kcal for a 78.2 g Yum Yum. The jam doughnut is the closest swap by weight, giving you an almost identical amount of food for 74 fewer calories.
How many calories in a Greggs Belgian Bun?
371 kcal for 122.5 g, which is 303 kcal per 100 g. It is the highest single-item count of the sweet range and the lowest by weight, because it is a large soft bun rather than fried pastry. Per gram it is the most forgiving sweet thing on the counter.
How much sugar is in a Yum Yum?
16 g in one twist and 33 g in the two-pack, from 21 g per 100 g. One Yum Yum is 18% of the 90 g daily reference and the pack is over a third of it. Sugar is not the standout figure here, though: the saturated fat is.
How much saturated fat is in a Yum Yum?
8.6 g per twist, or 11 g per 100 g, which is 43% of an adult's 20 g daily reference. The two-pack takes that to 17 g, or 85%. The fat is sheeted into the pastry during lamination, so it is structural rather than something added at the end.
