And more often than not that metabolic disease is caused by the choices people make! We destroy this system through poor eating habits, sedentary lives and various other choices we make day to day.
The one thing I always find interesting regarding conversations about weight is this: Its always people wanting to lose weight asking other people who have weight to lose how they are trying to lose weight. No one asks the skinny people how they keep weight off, they act as if its "genetic".
If you want to stay heavy, continue to ask heavy people what they do to stay that way and pretend anyone who isn't in your shoes isnt make sacrafices you aren't willing to make.
