I was a heavy coffee drinker, then switched to black tea, and around 2-3 liters of water a day. Yesterday I had a black coffee, and I had been retaining water, after the coffee I wasn't any more. :lol:
I honestly can't see four cups of coffee stalling weight loss, unless you have it with a ton of sugar, cream or milk, even then loads of milk and cream shouldn't stall. I do know a lot of dairy can stall, but that tends to be among the diabete's mice, who eat loads of cheese.
