Hi Nora!

The answer to this is yes, and no. For most people, they have trouble getting enough calories when low carbing because ketosis has the effect of diminishing your appetite. However...Dr. Atkins does stress that eating low carb is not a free license to gorge yourself on low carb foods. As a guideline, I'd recommend shooting for 10-12x your goal weight, but never going below 1,200 calories a day. Many people find that they need to experiment a bit to find the right levels for them.
