Twinkies... yes please!

I haven't been feeling very bloggy lately and I think it's because I'm starving craving junk food & carbs.  My husband and 7 of this co-workers have decided to have their own "biggest looser" competition.  They have their weekly weight in and who ever looses the biggest percentage of weight wins that weeks weigh in and they are about to be on week 3 of the 10 week competition.  Just incase loosing weight wasn't enough of an incentive for these guys they decided to add money into their game.  At the start of the competition they all put $10 dollars in the pot and every week whoever wins the weigh in only has to put $5 in and the rest put in another $10 dollars.... After the 10 weeks is over the total amount of money to be won is $750 dollars!!  My husband is pretty hardcore when it comes to loosing weight and getting healthy... so as he is eating an egg white omelet for breakfast I'm eating a twinkie (he hates twinkies, so I don't feel bad eating it).  I have figured I can only go a few days without some sort of junk food lol.

I've actually been pretty good about eating really healthy with him but I'm human and still eat crap when he isn't around.  I'm finding it hard to be as into his diet as he is because I don't want to loose weight but do want a healthier life style. Any suggestions on finding the right balance of support/change?  Also, what are some of your favorite low calorie snack/ meals?  Is there such a thing as a low calorie good tasting dessert??
