Slimming World made its biggest changes in years at the start of 2026 — and if you've been on plan for a while, it can feel like the rug's been pulled from under you. The short version: Syns are now called Swips, you get three Healthy Extras instead of one A and one B, and healthy fats like avocado and nuts are now part of the plan.
The actual food choices haven't changed. The principles haven't changed. Most of what changed is terminology and a few tweaks to how Healthy Extras work. This guide breaks down every change so you know exactly where you stand.
The three main changes for 2026 are: Syns renamed to Swips, Healthy Extras expanded to three choices per day from a combined pool, and a new Healthy Fats category added to that pool.
Everything else — Free Foods, the SP plan, group sessions — remains the same. If you've been following the plan successfully, you don't need to start from scratch. The changes are designed to make the plan feel more positive and more flexible, not harder.
Swips stands for Slimming World's Individual Picks. They are exactly the same as Syns — the same foods, the same values, the same daily allowance of 5 to 15 per day.
Chocolate, crisps, alcohol, butter, sauces — all the same foods that were Syns are now Swips. The value of every single one remains unchanged. If a Curly Wurly was 5 Syns, it is 5 Swips.
The name change was made because the word "Syn" had negative connotations for some people. Slimming World's research showed the language of "sinning" was putting some potential members off joining. Swips frames the same foods as a conscious individual choice rather than something you've done wrong.
Yes. Swips are identical to Syns in every way except the name. The calculation formula hasn't changed. The values haven't changed. The daily allowance hasn't changed.
Every guide on this site that mentions Syns still applies. If a food has a value of 6 Syns, that value is now 6 Swips. All existing syn lists — including every guide on this site — remain accurate. Just substitute the word.
The daily Swips allowance remains 5 to 15 per day — identical to the old Syns allowance. Your consultant will advise on the right amount for you based on your weight loss goals and the speed at which you want to lose.
Most members work with 10 to 15 Swips per day. Keeping to 5 Swips gives faster loss. There's no benefit to using fewer than 5 — they're built into the plan for a reason.
From January 2026, members choose three Healthy Extra portions per day instead of one Healthy Extra A and one Healthy Extra B. The three portions come from a combined pool of calcium choices, fibre choices, and the new healthy fats choices.
The key rule: at least one of your three Healthy Extras must be a calcium choice. So you can't use all three on bread. But you can have two fibre choices and one calcium choice, or one fibre, one calcium, and one healthy fat.
| Old system | New system (2026) |
|---|---|
| 1 Healthy Extra A (calcium) | 3 Healthy Extras from combined pool |
| 1 Healthy Extra B (fibre) | Must include at least 1 calcium choice |
| No healthy fats category | Healthy fats now included in pool |
In practice this means more flexibility. You could now have two portions of bread and one portion of cheese in a day — that wasn't possible under the old A+B system.
Healthy fats is a brand new category introduced in 2026. It includes foods like avocado, nuts, and olive oil — foods that were previously Synned but are now treated as Healthy Extra choices because of their nutritional value.
This change reflects current nutritional thinking around unsaturated fats. Previously, avocado and nuts carried a syn/swip cost because of their calorie density. Now you can choose one of your three daily Healthy Extras from this category instead.
The official Slimming World app has the full healthy fats list with portion sizes. The category includes whole nuts, nut butters, avocado, and oils — all with specific portion guidance.
The Healthy Extra B choices — now part of the combined fibre pool — remain largely the same as 2025. Fibre choices include wholemeal bread, wholegrain cereals, rye bread, crispbreads, and high-fibre crackers.
Common fibre Healthy Extra choices include:
| Food | Portion (approx) |
|---|---|
| Wholemeal bread (800g sliced loaf) | 2 medium slices (~60g) |
| Warburtons Thins | 1 thin (~58g) |
| Wholemeal English muffin | 1 muffin (~65g) |
| Wholemeal pitta bread | 1 pitta (~60g) |
| Rye bread (high fibre) | ~60g |
| Ryvita Crunchy Rye | 4 crispbreads |
| Weetabix | 2 biscuits |
| Porridge oats | 35–40g dry |
| Alpen Light bar | 2 bars |
Portions are approximate and based on standard Slimming World guidance — always verify in the official app or with your consultant as portion sizes can vary by specific product.
Yes. Every existing Syn value is now a Swip value. The numbers are identical. Nothing was recalculated when the name changed.
All the syn guides on this site remain accurate for 2026 — just read "Swips" where you see "Syns." If your food diary uses Syns language, it still works. If your Slimming World app still says Syns in some places while updating to Swips, both mean the same thing.
Two other terminology changes happened alongside the Swips rename. Body Magic — Slimming World's activity programme — is now called Slimming World's Active Lifestyle Programme. IMAGE Therapy, the group support session format, is now called Slimming World's Support System.
Both of these are name changes only. The activity guidance and group support structure remain the same. If you've attended group sessions or followed Body Magic guidance, nothing about how they work has changed.
