Anecdotally, I have metabolic syndrome, which is part of the reason why I am so interested in the process and issues surrounding it. My body naturally burns about 15% fewer calories than it should all things considered, I would have to exercise for about 30 minutes every day to equal the same caloric burn as a twin of mine without the issue's sitting on their butt all day.

Despite that, I've lost almost 100lbs from dieting (intermittent fasting, ECA stack, even Keto for a while) over the last several years but I'm still trapped by the condition as the less I weigh the worse the syndrome gets. Increased hunger, depression, lethargy, exhaustion, body temperature decreasing (painfully cold hands even in the middle of summer), insomnia, irritability, all of these issues hit me at the same time and get worse the lower my weight goes.

I don't have diabetes, blood sugar and a1c are normal, no hypertension (actually hypotensive), generally decent health otherwise. Diabetes and excess fat isn't the disease, it's the visible symptom of a larger issue caused by the American diet and lifestyle. Sure, it's my fault (and my parent's fault) that I became obese as a child but now the typical solutions for the issue simply do not work, and people who refuse to see that there is more going on than simply "fat pigs won't stop eating" do literally less than nothing to help solve or identify the core issues.

The food control / prevention of overeating solution works to prevent people from ending up like this, but rarely works to solve the issue once it has taken root, not to mention that the body typically doesn't lose fat cells once they have been created so even if you get to a normal weight you basically have a human fat cell parasite hungrily clawing at every morsel of food you eat more than what you immediately need permanently attached to your body unless you undergo surgeries to physically excise it from your body. (This is one of the reasons why most contestants on the Biggest Loser end up regaining their weight within a short amount of time, for instance. It's far easier to refill empty fat cells than it is for fat cells to be built by the body.)

This is why obesity is a crisis. Not just because of diabetes, but because the tools that we have to fight obesity once it arrives are insufficient for the job.
