First of all, PLEASE don't bash Atkins,
Dek. I'm sorry that it wasn't the right thing for your husband, but that doesn't mean it's not sustainable for other people. We have a woman on this board who has sustained a 100+ pound weight loss on Atkins for over two years.
The book doesn't say to eat as much eggs, meat and cheese as you want, either. Cheese is limited to 3-4oz a day. Eggs DO have carbohydrate (.6 grams, to be exact) in them and the book suggests that each be counted as one carb to keep the math simple. Cheese is also to be counted as one carb per ounce (as cheese has some trace carbs in it). So in that sense, the amount of eggs you eat is definitely limited by the total amount of carbs you can eat in a day. Sausage is something I'd stay far away from unless I knew how it was cooked, as sausage can contain carbs (the book lists pork sausage links as having 2 carbs per 2 links).
Her breakfast, if there were two slices of cheese used (with 6 eggs, it may have been more than that) could have been anywhere from 8-12 grams of carbs...which would have taken a HUGE chunk out of her total for the day. So...I think she needs to re-read the book. Atkins is NOT a no-carb diet, but it is a low-carb diet...and your breakfast companion might not be understanding how carb counts work.
I'm on Atkins--I count my carbs, but I also count my calories. It works for me. In the beginning, I had to actually make sure I was eating ENOUGH calories, because Atkins is a VERY filling diet and it almost eliminated hunger pangs for me. I eat meat--Chicken breast, pork loin and cube steak regularly (in 4-6oz portions), I eat vegetables (Spinach, Romaine-based Salad, Broccoli, etc) two or three times a day, and have nuts and berries a few times a week right now. I'm eating more vegetables than I ever have (I've never been a veggie person, but I'm learning!). I believe that a Low Carb way of eating IS sustainable over the long term, if you transition into maintenance slowly and the right way. Do I expect to eat Induction-level carbs the rest of my life? Absolutely not. It wouldn't be realistic for me. Do I think that I'm ever going to be able to eat the "Typical American" amount of carbs and maintain? No. I think the right spot will be somewhere in between for me, and it's my job to find it when the time comes.
I'm sorry I got off on a tangent here...Just sharing my experience.
Like, my favorite breakfast lately?:
Spinach, 1 Over-Medium Egg, 2 slices of Bacon, 1 slice of american cheese (like a bacon/egg/cheese sandwich on top of spinach): 280 calories and about 4 carbs. It keeps me satisfied and is delicious.
