Part of doing Atkins is to make sure you eat. I know it doesn't make intuitive sense, but you have to keep your calories up, especially since you have a job that burns a lot of calories. My suggestion is to eat at least 1400-1500 calories a day (if not more!) and get most of them from fat. The ratios suggested here are 65-70% of all your calories should come from fat, 25-30% protein and 5-10% carbs. You might want to get a free account at www.fitday.com to help you track your food.

Weight also fluctuates a couple of pounds normally. If you have dieted before, your body might be building muscle which will make the scale go up at first, but it will go back down as you lose fat. DO NOT listen to those people who are trying to get you to switch to low fat.

BTW, love the puppy picture!
