How long does it take for you to burn off party fat?

I had a barbecue 2 days ago on July 1st and its July 3rd and I've already lost my party weight which I believe is due to the peppermint tea and the yogurt with lemon juice and the yogurt with fruit that I had. I also ate a diet that was less than 10% grain yesterday and had only meat and fruit and veggies and dairy and nuts.
