When have you seen the fashion world with anyone fat? If ever there is that I know not of, most of what I see I see are comprised of stick models. The thinner the better.
Many have resorted to starvation that almost always resulted to bulimia because they fear they are getting fat. Not good. If you want to slim down and yet you do want to go as natural as possible and treat the cause instead of the mere effect, you might want to try bioidentical hormone replacement therapy. You will not only achieve your weight and size goal but you will also be happy.
Then you can confidently join any fashion show without anxiety or fear of being rejected or looked down by others who are slimmer than you. You have to accept yourself first, though, if you want others to accept you.
Go ahead, fit in those fashionable clothes you are eyeing!
