## Variety by variety

| Item | Per 100 g / 100 mL | Serve | Energy | Calories |
|---|---|---|---|---|
| Tim Tam Original | 2,193 kJ/100 g | 18 g | 395 kJ | 94 Cal |
| Tim Tam Double Coat | 2,212 kJ/100 g | 19.5 g | 431 kJ | 103 Cal |
| Tim Tam Dark | 2,170 kJ/100 g | 18 g | 391 kJ | 93 Cal |
| Tim Tam Choc Mint | 2,136 kJ/100 g | 18 g | 384 kJ | 92 Cal |
| Tim Tam Salted Caramel | 2,054 kJ/100 g | 18 g | 370 kJ | 88 Cal |
| Tim Tam Gluten Free | 2,229 kJ/100 g | 18 g | 401 kJ | 96 Cal |

## How it adds up

| How it is eaten | Energy | Calories | Protein |
|---|---|---|---|
| One biscuit | 395 kJ | 94 Cal | ~0.8 g |
| Two with a cuppa | 790 kJ | 189 Cal | ~1.6 g |
| Half a pack (5 biscuits) | 1,975 kJ | 472 Cal | ~4 g |
| Full 200 g pack | 4,386 kJ | 1,048 Cal | ~8 g |

## 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.
