Hi there, low fat yogurt isn't on the HEA list at all, it has to be synned but is very low in syns
Low fat yogurt,
greek style, 100g, 1 syn all plans
fruit flavour, 100g, 1.5 syns all plans
natural, 100g, 0.5 syn all plans
Just editing to add that very low fat yogurts are free and you should have no trouble getting them.
