You basically have 2 choices here.
1. You lose the weight.
2. You don't.
Nothing but good will come of your health and lifestyle with the first choice. The second choice, however, contains a lot more risk. Health-wise, you could get diabetes, heart disease, a fatty liver that may fail on you, corroded arteries that could lead to a heart attack.
Was that swift enough? :P
The good news is, this place is AMAZING. All the people here are AMAZING. If you're looking for a strong support network, you've come to the right place. We all have tid bits on what works for us with weight loss. I chose calorie counting and exercise because it is something that I can do the rest of my life without having to worry about "reintroducing" real food back in to my life.
The first thing I started out with was eating whole foods, non processed foods, smaller portions, more frequently. Since then I have removed things like red meat from my diet (personal choice, not for health reasons), HFCS (wherever possible), and have slowly been able to lower my calories. I am not losing "20 pounds in 20 days," or anything like that, but I am losing at a comfortable rate, and I'm growing stronger and stronger every day.
Next hurdle to kick, smoking!
Good luck

You can do this, you just have to be realistic about it. Congratulations on the dream job, you are worth the weight loss!
