One thing I've been doing lately is putting a
LOT of cream and sugar in my tea.
I don't think that'll help a lot, but I guess every bit counts

1 teaspoon of sugar is about 15-20 calories, depending on who you ask.
5 cups of tea a day with 2 sugars as opposed to none is 150-200 calories a day extra. If I remember my feeder maths, it takes 3500 calories to add a pound of fat ... so that's a pound every 3 weeks or 17 lb in a year JUST from sugar in tea
