Amanda Tiffen went from 30 teaspoons of sugar per day (unknowingly) to 6 teaspoons of sugar per day and in doing so lost 20kg and went from a size 16 to a size 8 in 9 months. This is the inspiring story of how two ordinary and busy working mums reduced their sugar consumption and, in the process, changed their lives for the better.
