Most Slimming World members are allowed 15 Swips per day. Swips is the name Slimming World gave to syns in January 2026 — the concept is identical, only the name changed. Your daily allowance of 15 applies to all food and drink that is not Free Food or a Healthy Extra.
Slimming World rebranded syns as Swips in January 2026. The calculation method, daily allowance, and food values are all unchanged. If you search for syn values, the numbers you find are still correct — they are now officially called Swips values. This site uses both terms interchangeably.
The standard daily Swips allowance is 15 for most members. Your allowance can be higher if you have a higher starting weight or are male.
| Starting weight | Daily Swips (women) | Daily Swips (men) |
|---|---|---|
| Under 16 stone | 15 | 20 |
| 16–20 stone | 20 | 25 |
| Over 20 stone | 25–30 | 30+ |
Your consultant sets your personal allowance when you join. The figures above are typical starting points — your individual allowance may differ.
Three factors determine your allowance: starting weight, gender, and weight loss goals.
Men require more calories to maintain weight than women of the same size. A higher allowance reflects the higher baseline calorie need rather than a more lenient plan.
Heavier members have a higher total daily calorie need, so a larger Swips allowance still keeps them in a calorie deficit relative to their maintenance needs. As weight drops, the allowance is typically reviewed downward.
The quickest method is the Slimming World app, which lists official Swips values for thousands of products. For foods not in the database, use the rule of thumb: 1 Swip per 20 calories. A 200-calorie product is approximately 10 Swips.
This formula is a rough guide — the official calculation also factors in fat and sugar content, so some products have more Swips than the calorie formula suggests. The app is always more accurate than the formula.
Going over by 2–3 Swips occasionally does not derail weight loss as long as the rest of the week stays on plan. Slimming World is designed to be sustainable — one imperfect day does not undo consistent effort across the other six.
Regularly going over by 5–10 Swips per day will slow or stop weight loss. The plan works because the combination of unlimited Free Food and a controlled Swips allowance creates a natural calorie deficit. Consistent overruns remove that deficit.
Not necessarily. Many members lose weight faster when they use their full allowance than when they severely restrict Swips. Eating too little overall leads to hunger, cravings, and higher-Swips binges later in the week.
The plan includes a 15-Swip allowance deliberately — it keeps the diet sustainable long term by allowing treats without guilt. Members who save all Swips for one day often report a binge-restrict cycle that slows overall progress.
Carrying Swips forward to another day is acceptable on the plan and works well for social occasions or meals out. Saving 5 Swips a day across three days gives a 15-Swip buffer for a Saturday night out without going over the weekly total.
Saving a full week of Swips for one day is not recommended. A single 105-Swip day is nutritionally very different from 7 days of 15 Swips, even if the weekly total is the same.
Swips is the new name for syns, introduced by Slimming World in January 2026. The daily allowance (15 for most members), the calculation method, and all food values remain unchanged. Swips and syns refer to the same thing.
Swips values are calculated using a formula based on calories, saturated fat, and sugar content. They are not the same as calories — a food can be low in calories but higher in Swips if it is high in fat or sugar. Always check the Slimming World app for official values.
You can eat 0 Swips per day if you stick entirely to Free Foods and Healthy Extras. This is not required and is not recommended long term — the plan includes a Swips allowance so you do not feel deprived, which is what makes it sustainable.
