That's so interesting how caffeine (or some other component of coffee) can really affect weight loss. I've been coffee & caffeine -free for over a week now and I wonder if that's what made the difference in getting some lbs off this past week. However, I did make a cup of coffee today using a 2nd brew of the grounds my husband used this morning, lol. My friend loves her coffee like that so I thought I'd try it too. I wonder how much caffeine is left when you brew the coffee grounds again?
