I think the strength training thing is a great idea. Try to do some reading about lifting weights on the internet. I have learned a lot about it over the last couple of weeks. Those muscles really burn the fat off.
As for trying not to go to the fridge or the pantry... hmmm, I am still trying to figure that out.
Planning is one thing, make sure that you know what you are having for your next meal or snack, then you won't be starving and have potential to eat something quick and not so good for you.
Stay busy... keep you mind off of it. If you start to crave something think of something to get you busy.
These aren't the greatest tips, but they might help.
