In Dr. Atkins book "The Atkins Essentials" on page 278 there is a question: "I thought I wasn't supposed to be hungry when I do Atkins, but I am. What gives?" Dr. Atkins replies: "If you're hungry, eat! If you're starving, you should have eaten 30 minutes ago. Just as overeating can cause your body to resist weight loss, so can eating too little, which slows down your metabolism. Eat adequate amounts of food and eat regularly. Also, be sure to eat enough fat (the natural kinds, like olive oil, fatty fish and avocado); foods containg fat and protein are the most satiating. Not eating enough fat will also interfere with your body's ability to burn its own fat for energy." Hope this helps you out.
