That's a fantasic weight loss. Well done! Being a man, I must admit that it is a little easier for us. We have far fewer "water" issues and less weight variability than women, which helps us keep more motivated. We often get to exercise more as part of our daily lives because we generally do more physical activities than women, be it around the house or at work (one of the reasons we live less long - we simply wear our poor selves out
).
So lucky him. But lucky you too with such great progress! As a guy, I hope I can match your loss some day.
