Speaking just as a member, it more depends on what kind of calories they were. The proportions should be about 65% fat, 30% protein and 5 % carbohydrates.

Atkins always said that calories weren't important during Induction. It was more important to get into ketosis. Eventually I think they have to be noticed but not kept low.

You'll find lots of references here to eating 10-12 times your weight in calories. But people differ on whether it's times your current weight or your target weight.

The important thing is not to let your calories go below 1200 per day no matter what. And keep the carbs to at least 20, mostly from vegetables and salad. Then start raising them each week. The body can adjust to a low carb level if you stay on Induction or below, and then you have nowhere to go if you should stall.

Atkins had 30 years of experience with patients that told him that "lower than Induction" levels of carbs didn't help with faster or greater weight loss.

Hope this helps. I don't think that many calories is bad.
