ok basically im one of those guys that went from really skinny with a very fast metabolism and did not store fat at all(about 140lbs) to about 250lbs within a small amount of time! now im back down to about 170-175lbs because im not juicing, but i just talked to a trainer and he said that because i did this and put some fat on when i was big, my fat cells "know" how to store fat and kind of have a "fat memory" if you will and he said that it will be easy for me to store fat now for the rest of my life??? is this true can a persons ability to store fat change because of something like this??? or is it still the same and what he said is bogus?
