The Healthy Extra B list for 2026 covers fibre choices — wholemeal bread, cereals, crispbreads, and oats. From January 2026, Slimming World members choose three Healthy Extras per day from a combined pool instead of one A and one B. At least one must be a calcium choice.
The B choices themselves haven't changed. The same breads, cereals, and crackers that qualified in 2025 still qualify in 2026. What changed is how many you can have — previously one B per day, now potentially two B choices in a single day if you use all three HE slots on fibre and calcium rather than two B and one A.
This guide lists every Healthy Extra B choice with portion sizes for 2026, explains the new three-choice system, and covers the most commonly asked questions.
The Healthy Extra B is the fibre category of Slimming World's Healthy Extras. B choices include wholemeal bread, high-fibre cereals, oats, and crispbreads. From 2026, these are part of a combined pool with calcium choices and healthy fats — you choose three per day with at least one being calcium.
B choices provide dietary fibre that Slimming World considers important enough to include outside the Free Foods system. Most of the foods on the B list are carbohydrates that would otherwise carry a syn cost — your daily Healthy Extra B effectively makes them free within the portion size listed.
The table below covers every common Healthy Extra B choice with portion sizes. All portions are the standard serving that qualifies as one Healthy Extra B.
| Food | Healthy Extra B portion | Approx calories |

| Wholemeal bread (800g sliced loaf) | 2 medium slices (~60g) | 140 kcal |
| Warburtons Wholemeal Thins | 1 thin (~58g) | 135 kcal |
| Wholemeal English muffin | 1 muffin (~65g) | 155 kcal |
| Wholemeal pitta bread | 1 pitta (~60g) | 145 kcal |
| Rye bread (high fibre) | ~60g | 140 kcal |
| Ryvita Crunchy Rye crispbreads | 4 crispbreads (~40g) | 140 kcal |
| Ryvita Dark Rye crispbreads | 4 crispbreads (~40g) | 136 kcal |
| Weetabix | 2 biscuits (~37g) | 136 kcal |
| Shredded Wheat | 2 biscuits (~45g) | 158 kcal |
| Bran Flakes | 35g | 120 kcal |
| Porridge oats (dry) | 35–40g | 140 kcal |

Portions are based on standard Slimming World guidance. Always verify in the official app or with your consultant — portion sizes change when manufacturers update products, and some products listed above have regional or supermarket-specific variants with different serving sizes.
From January 2026, members choose three Healthy Extras per day from a combined pool of calcium choices, fibre choices, and the new healthy fats category. The old system allowed one HEA and one HEB per day. The new system allows three choices total, with at least one being calcium.
The practical difference: you can now have two portions of bread in a single day if you use two of your three HE slots on fibre choices. Under the old system, a second portion of bread cost syns. For members who eat a sandwich at lunch and toast in the morning, this removes a daily syn cost that previously added up across a week.
Yes — you can use two of your three daily Healthy Extra slots on B choices, as long as your third choice is a calcium option (Healthy Extra A). So you could have two portions of wholemeal bread and one portion of milk or cheese in a day.
What you cannot do is use all three slots on fibre choices. At least one must be calcium. You also cannot split portions across two slots — each slot is one full qualifying portion.
Wholemeal and wholegrain breads qualify as Healthy Extra B on Slimming World. White bread does not qualify. The qualifying brands most commonly stocked in UK supermarkets include Warburtons Wholemeal, Hovis Wholemeal, and most own-label wholemeal loaves.
Two medium slices from an 800g wholemeal loaf is the standard portion. Thicker-cut loaves may only allow one slice per HEB portion — check the weight against the ~60g qualifying portion size. If the bread is marketed as "50/50" (half white, half wholemeal), it may not qualify — check the official app.
Standard sourdough does not qualify as a Healthy Extra B on Slimming World. Most sourdough loaves are made with white or light flour rather than wholemeal, which means they don't meet the fibre threshold for HEB qualification. Wholemeal sourdough may qualify — check the specific product in the official app.
Yes — 35–40g of dry porridge oats qualifies as a Healthy Extra B. This covers Quaker, Scott's Porage Oats, own-label supermarket oats, and most standard rolled oat brands. Flavoured instant sachets (like Quaker Oats So Simple) typically do not qualify — the added sugar and flavouring takes them off the list.
Plain oats used in overnight oats, baked oats, or traditional porridge all qualify at the same 35–40g dry portion. Blending oats does not change the portion size or qualification — some members blend their HEB oats into smoothies or savoury dishes without issue.
Healthy fats is a new Healthy Extra category introduced in January 2026. It includes avocado, nuts, nut butters, and oils — foods that were previously synned but are now available as one of your three daily HE choices.
Common healthy fat choices include half an avocado, a 30g portion of mixed nuts, and a tablespoon of olive oil. The full list with specific portions is in the official Slimming World app. This is the only new category added in 2026 — the A and B lists themselves remain the same.
