i now know why they are 70% less fat, cos there is 70% less crisps than normal packets
no joke there is about 6 crisps in the bag

True!

At WW we were told to buy multi pack crisps because they always slightly smaller eg maybe 25g instead of 35g. You didnt notice and still felt like you were eating a full pack of crisps so were satisfied. My problem was I would have just had 2 bags then
