Syn values,
A to Z.

Syn values tell you how much of your daily Slimming World allowance a food costs. Every member gets between 5 and 15 syns per day — most people settle on 10 to 15 and still lose weight consistently. Free Foods (marked with a green dot below) cost nothing; everything else is counted from the table on each food's page.

Every value on this site is checked against current UK packaging and the official Slimming World app, then updated when products change. Where a food has multiple brands or portion sizes, the full guide breaks them down side by side so you can pick the option that fits your plan and your budget.

If you are looking for foods within a specific syn budget, use the foods under X syns tool. For browsing by type — dairy, bread, snacks, sauces — try browse by category.
