Being through a major weight loss before - 100 pounds - what I missed then was my physical strength. With a prior weight loss I lost both fat and lean muscle mass.
In the back of my mind when starting IP was "Is this going to happen again?"
But, at this very moment what will I miss about being "big", "overweight", "fat"? Not a bloody thing. I'm not worried in the slightest - I don't believe in the whole Nutty Professor thing where I will turn into a completely different person - i.e. a jerk - personality wise.
I still have my height and am will still be a bigger than average person who can be helpful - "Sir, can you reach the item on the top shelf for me?" type of help.
Because I'm overweight no one has ever asked "Hey fatty, can you stand/sit on this to keep it anchored to the ground?"
