Decide what counts before day one
Most no sugar challenges fail on a definition, not on willpower. Day four, someone eats a granola bar, is not sure whether it counted, and decides it did not. By day nine the rules have quietly become whatever was eaten. Write the rule on the sheet before you start, while you are still strict.
There is no official version. The common ones, from strictest to loosest:
- No added sugar: nothing with sugar, syrup, honey or a sweetener on the ingredient list. Whole fruit is fine. This is the version most people mean.
- No added sugar and no sweeteners: the same, plus no diet drinks or sugar-free sweets. Harder, and aimed at the taste for sweetness rather than the sugar itself.
- No sweets: no desserts, sweets, cakes, biscuits or sugary drinks, but ketchup and bread are left alone. Easier to keep, and a fair first attempt.
- No sugar at all: also no fruit and no milk sugar. Rarely kept past a week, and not something to try without a reason and advice.
