Yes, to your question about men losing better than women. That seems to be the case frequently. My DH lost about 80 pounds quite easily in about 7 months. It's been five years and he'd crept back up a little recently. He got really strict again and he's lost the excess. So, YES, you can do quite well with Atkins. Just be sure to follow the plan as it's laid out in DANDR. Good Luck!
