I've just taken a quick peek at the Atkins Gram Counter and it says - 5 green olives = 2.5 grams and 5 black olives = 0.7 grams. I love both the green and black ones but have been staying away from the green ones because of the high carbs. So what do I do now!!??!! The green olives have more fat and calories though for those counting calories. I must say sometimes getting things right does get a tad confusing. Will probably stick to the black ones though.
