Coca Cola Zero - Sweetened with aspartame and acesulfame potassium., the reason this is different than Diet Coke is Coca Cola Zero is a sugar free version of the Classic Coke formulation.
In other words, this is meant to be a sugar free version of the red cans of Coke you know and may or may not love. It has a redder, deeper color close to the color of Classic Coke and tastes far less like a diet soda (by many accounts) than Diet Coke.
I love Coke Zero. Always have. I don't get fat off of it. I understand that for a person who consumes a shitload of sugar that the sweetness (although not sugar) may trick the body into thinking it has sugar and will signal the release of insulin to stabilize this "fake" sugar and cause all the responses that sugar would under normal circumstances. Too bad, so fucking sad.
this only happens in some folks, not all-- and usually not those heavily involved in the fitness industry. There are no calories for my body to store and it is not easily fooled. I can diet into the single digits on Coke Zero. I love it chilled and from a can. Gotta have one. Every day.
ASSSSSSSS per tame.... will prolly jack me up some day, but NOT today.
