I used to be fat. I dieted. I exercised. Nothing worked. Finally, I just turned to the only permanent weight loss method with any real demonstrated results==gastric bypass.
I used to think that it was just the fact that doctors made my stomach smaller that was going to change my body. I could not have been more wrong. The doctor removed my duodenum and part of my intestines. As a result, hormones have changed in my body.
I now have totally different taste buds. Things taste sweeter. I used to wonder how anyone could be anorexic, because not eating would cause me pain. Now, not eating is a breeze.
There is something different in the bodies of fat people. I am still a fat person in a skinny person’s body. They have manipulated my hormones. It isn’t the small size of my stomach that is controlling portions, and oh, now I am thin. No, it is they cut something out that changed my freaking body chemistry to be like skinny people body chemistry. My hormones have changed enough to alter underlying hormonal disorders I have. I suppose that’s why it works on diabetes, too.
They don’t know enough about why my body craved catbs, especially junk ones. There is a lot of research about it. Some of it may actually stem from a response to deprivation. When they followed up with concentration camp victims over the years, researchers noticed an odd characteristic about many of them. They binged on food.
This led to the famous Key studies at the University of Minnesota where they deprived students severely of food within reason (human ethics board). Then, they followed their behavior. Sure, enough. These students developed binge eating.
So, the poverty I suffered as a child may well be why I was fat. (If you are questioning if I was starved enough I would share the anecdote that child welfare workers received reports from our teachers that my brother and I were begging other children for food at lunch). Just one theory out there so far. There’s one from microbiology that’s great, too, but guess what, no matter what it is definitely much smarter than the thought, “People chose their body size.”
