Anne, it sounds to me like you need to eat more meat. This is a fairly common phenomenon when people start ZC; even petite women used to nibbling on salads find they can pack away several pounds (yes, pounds) of meat a day, especially at the beginning.

My advice to you would be to eat plenty, and eat more often. Don't worry about "overeating." It will all balance out.

Definitely drop the sweetened soda. It may seem harmless, but sweet tastes derail almost everybody.

Good luck! Glad you're giving it another try. (I've been ZC since 2009.)
