Scientifically - caffine does effect weight loss. However; I think it varies person to person. For the first 2 month of eaing this way, I had my cup of coffee every day and I lost over 20lbs. The last few weeks I've only had maybe 2-3cups a week and my weight loss has slowed down. I know it didn't slow down due to not drinking the coffee but it certainly didn't hurt the first 2 months.

I think sometimes people who want to lose more and stop a stall will adjust their menu and then they lose and blame coffee as the culprit.

To each his own!
