My advice would be to take it one day at a time. Some days I'm a little frustrated at how much weight I have to lose (I'd like to lose 80) and the scale doesn't move.
For breakfast on the go...I've heard of breakfast muffins. I've nver tried making them so I'm not sure how satisfying they are. What about breakfast burritos--eggs and vegetables. Protein keeps you fuller longer. Apples are good too.
Good for you signing up for a gym program. Look forward to hearing all about it
