Can confirm. I am (was) really, really addicted to sweets. I thought I couldn't function without them. Coke Zero/Pepsi Max are doing wonders for me. I'm 40+ years of age, drinking about 2-4 cans a day and went down from 101 kg obese BMI to 79 kg normal BMI in a few months just by removing excess sugar and a little calorie counting. No effort whatsoever, and the zero-free sodas cover most of my "sugar" requirements.
