Pretty much... it's weird at first... You can't eat the "real food," just the stuff that makes the "real food" taste good! lol
For instance, you can't have a baked potato... But you can have the bacon, chives, butter, cheese. You can't have milk (you can, but just a few ounces. It's pretty high in carbs), but you can have cream. No margerine, but butter is great. Can't have wheat thins, but you can have pork rinds.

That makes it hard for me to consider an Atkins type diet. I go thru a gallon of 2% milk every few days. Love the stuff. Fortunately, I am not (too) fat (6'2", 198#).
