Hi guys.
Guess I'll start by introducing myself. I'm a norwegian male, 39 years old, married, father of two kids, and are working as a Engineering manager in the oil industry here on the west coast of Norway.
I'm one and a half week away from undergoing gastric bypass, and are in the final pre op diet. So far I have lost 13 kg since i started the diet, and needed to loose 7,5 kg so are in good shape.
So how did I end up here?.
I have always been heavy set, and spent my teens and early 20 playing ice hockey, power lifting and martial art. I went to serve in the Norwegian army, and served for three years, before I went to college studying engineering. I was used to eat large portions , but kept the kilos away, due to the simple fact that worked my ass of as a soldier. That kinda changed when i started studying for twelve hours a day. Then the kilos crept on, and they haven't left me since. I steadily gained weight. 
I tried everything to loose the weight. Low carb diet, calorie counting, nutrition shakes, you name it, I've tried it. Lost weight but it came back, plus interest. 
So a couple of years ago, I got diabetes 2. That was the last drop. I realised that i needed, help, and went to my primary physician. He agreed that Gastric bypass would be the best solution for me, and referred me to the hospital for evaluation. The whole process took about a year, and I'm as I said one and a half week away from my surgery. 21 of oct is the date.
