Strange but true....

I was shopping today and as I am attempting to loose weight I am paying attention to the nutrient content of food.

I picked up a Weight Watchers Pizza (yes they exist), looking at the per 100g nutrient information, it stated that there was 176 calories and .8 grams of saturated fat, next to it was the per Pizza total, this was 236 calories and .9 grams of fat, nothing too sinister there I hear you say, except the Pizza was 100g in weight.... how can the nutrient information be different then !
