I have been drinking an EAS Advantage carb control shake every morning for breakfast in the car on the way to work and other than weeks that I've eaten off plan, I have not seen any change or slowing in my weight loss at all. I either drink a chocolate one, or a vanilla one with a packet of instant coffee and a bit of chocolate flavored Splenda sweetened syrup. Fabulous substitute for a Starbucks skinny latte for me...
