How Estimated Calories Are Calculated
When official nutrition is unavailable, calorie values are estimated using menu-item keywords and then adjusted by portion size. These values are directional for comparison, not medical nutrition advice.
- Base estimate: item-name tokens (for example burger, fries, salad, pizza, shake) map to baseline calorie ranges.
- Portion weighting: ounce and gram values adjust the estimate (about 8 oz = 1.0x, about 230 g = 1.0x), then the value is capped within a safe range.
- Size modifiers: small/kids items apply a lower multiplier, while large/xl/family/double items apply a higher multiplier.
- Final output: estimates are rounded to whole calories and shown as Estimated in the source column.
