Hello and welcome. New here myself
I can tell you from experience and what I have read - Guys/Men loose weight faster than women. Im sure someone here can give you specifics on why -but I myself am not sure.
Also, depending on your starting and goal weight, loosing may be a bit more difficult. Example..
If your 250 and you want to be 200 - the first 20 or so lbs might be easy, but the next 30lbs are goingn to be tougher. You will have to work harder.
Where as if you are 350 going to 200 - the lbs fly off pretty fast and painlessly as long as you keep up to a routine.
Then again, this all could be bunk and it all depends on your body. You have to do what works for you.
