yes and no
When I was in high school and thrown off the football team for chewing out the coach I went through a huge weight gain -- coincided with drinking tons of soda and such
Normal weight was 180, but shot up to 240, but easily lost it within a few months doing tons of situps, pushups, and eating nothing but a couple Peanut Butter and jelly sandwiches a day.
Weight was fine for years until a post-relationship depression went on (when you work hard for years to keep a relationship going then decide fuck it), in my mid-late 20s, a bunch of health issues arised and shot up again but instead of from 180 to 240 in a matter of a year or so, went up to 360 in 5 years. So I'm here in my early-mid 30s with newly diagnosed stage 3 fibrosis and type 2 diabetes.
I'm not accustomed to weighing a lot so the changes I went through were all debilitating to me. Apparently after MRI's and such I had fractured my spine as a kid but never knew it until I had this weight gain, then moving to another house caused me serious injury to where I need facet injections in my lower lumbar (soon to be some sort of ablation) as simply taking out the trash caused extreme amounts of pain to my back.
In the US, we're not educated enough how utterly useless carbs and especially sugar are in the diet, and how easily we can get into dangerous territory without thinking about it. Given how it's turned into a serious societal issue where kids in their 20s are having fibrotic/cirrhotic livers without even being alcoholics or drug addicts, it really points to an education being necessary. Since being in Canada, I've noticed the education is a little better, but still needs improvement. It's definitely a western problem, where we're taught to be good little excess consumers with little regard for our health. It's up to us to change that.
My surgeon decided on a 12 week pre-op liquid diet that I started Feb 1st, far longer than I see anyone else with, already I went from 350 pounds to 314. I'm thinking if I really have to go all 12 weeks (OR date already confirmed April 20) I'm likely gonna be in the 200s before surgery. Some have said why not be on this miserable diet for so and such amount of time to get back down to normal weight, but sometimes for us mechanisms of hunger (satiety) we can't control are required to be corrected. In my case, the surgery should accomplish this. Also, a very important point, that for many of us who "become" this way, it's up to us to recognize where we screwed up and work to change it. Personal responsibility is a must.
