The useful comparison
Every Tim Tam variety lands between 2,050 and 2,230 kJ per 100 g, so choosing Dark over Original saves about 4 kJ a biscuit. The variety does not matter. The count does.
Two biscuits a day, every day, is about 288,000 kJ a year. Logged, that is a planned treat inside a budget. Unlogged, it is the most common reason an otherwise sensible week does not add up.
