Just a note about snacking....
You should eat only because you are hungry. You shouldn't be eating for the sake of eating or because you are bored. Dr. Atkins said that we do not have to count calories, but calories do matter and if we eat in excess we will gain or not lose weight.
When you are in ketosis/lipolysis, you will find that your appetite will decrease. So snacks might not be necessary at all.
And be careful about eating "high protein". Atkins is a high fat diet, not a high protein one. Dr. Atkins wrote that excess dietary protein is converted to glucose which is eventually stored as glycogen and fat. Furthermore, it's the fat that will keep your appetite satiated between meals.
