My "bomb" diet was to exercise to keep from falling into a deep depression - and I lost quite a bit! I am not sure if I would have without that push.
When we got back together and were planning the wedding, I gained a little back. But I now keep a journal with what I eat, and I don't eat everything my husband does. If we are having any main dish, he eats more of the main dish, while I usually make a big pan of veggies to go with a small amount of the main dish. I love cooking up some green and yellow squash, along with a lot of mushrooms and onions in a pan, and it's very few calories!
