I'm just wondering, if you have type 2 diabetes can you eat lobster without the butter?

Yes: You can eat anything, but you have to do it in a well-balanced fashion and in moderation. You need to eat three meals a day, no snacks, and restrict your total caloric intake to less than you're burning off with exercise. It's 3500 calories to gain or lose a pound. You can even have butter -- but, you have to limit the amount of lobster eatenat one sitting, how often you eat it, and with what else.
