Blonde said:To the OP - Your office girl sounds like someone who really wants to believe it's OK to eat rubbish to me.
I'd avoid any sugary processed crap like the plague. It's all awful.
Blonde, I have to say that I strongly disagree with this aspect of your statement.
Without treats many people can't stick with a monk like discipline when it comes to either an exercise or dietry regimen.
Do you not accept that it is widely agreed that there is no such thing as 'bad' food, such as sugar, but rather that moderate use of all things is what is best.
I would suggest that advocating avoiding things "like the plague" is way OTT, although I acknowledge that you are entitled to your opinion.
