High metabolism means the body goes through stuff really fast. For me it’s hard to keep up with it, so I’m always at a deficit.

Type 1 diabetes shows up early 90% of the times (it used to be knows as juvenile diabetes). It’s a result of a autoimmune disorder that destroys the insulin producing cells in the pancreas (it’s a completely different disease than type 2). I was diagnosed when I was 11 yo. Type 2 is a metabolism disorder, often as a result of excess weight and a sedentary life style that develops insulin resistance. While type 2 continue to produce insulin, albeit now enough or not as effective because of fat, type ones stop producing it completely.

I guess everyone is built differently. I’m 34, 5 foot 7 and I’ve never weighed more than 60Kg. I have a very fast metabolism (I can have a meal and be starving within 2 hours) and I’m a type one diabetic. If I’m not in perfect control of my blood glucose for a bit, I start losing weight like crazy.

Im now weight 53Kg and struggling to gain any measure of weight.
