BE~ My son cut out Coke which led to cutting back on chips/Coke, fast food {as I am eating popcorn...closing bag now...} and he lost about 80lbs. So, yes, you are right about the losing weight. It took less than a year, but close to it maybe.
He just walked in for me to ask...he was eating cookies and cream ice cream out of the container.
I need to get back to eating well to be a good example, eh?
