^^ excellent explanation and information!
Hope you follow Janet's advice.
Just to clarify some very basic things:
1. ALL foods other than water contain calories.
2. There are 4 basic types of calories- carbs, proteins, fats, and alcohol.
3. Some foods contain calories from proteins, fats and/or alcohol, but not from carbs.
meat= fats and proteins, but no alcohol or carbs.
butter= fat, but no protein or carbs or alcohol.
vegetables= small number of carbs, little protein, no fat or alcohol (this is where most of your daily carbs should come from).
note that foods like eggs and cheese and cream contain small numbers of carbs, even if label says 0, as it was simply rounded down. you should track these carbs in your daily totals. an egg is roughly .6 per egg, an oz cheese is roughly 1.
4. the body needs calories to function, so no 1500 calories will not make you gain weight. don't worry about calories for time being- some people find they need to closer to goal weight, others do not. but in the beginning, just focus on carbs.
read the induction thread stickied at top of atkins forum. it is very useful ad easy to understand
