How many syns in battered fish? Battered fish and chips is a true British classic, but on Slimming World it’s one of those meals best enjoyed in moderation. Because of the batter and deep-frying process, it’s a high-syn option that can quickly use up a large part of your daily allowance.
So, can you eat battered fish on Slimming World? Yes — but only occasionally and when your syns allow.

If you’re planning a takeaway, you may need to use your entire 15 daily syn allowance — or even borrow from weekly syns — just for the fish.
