84% of konbini meals are under 500 kcal
Across 757 meal items from Seven-Eleven, Lawson and FamilyMart, the average is 331 kcal (median 297) and 84% come in under 500 kcal — versus 59% when eating out. Konbini food is designed to be combined, which makes portions adjustable by nature.

Disclosure is thorough too
All three publish protein, fat, carbs and salt for nearly every meal item, and Seven-Eleven and Lawson often add fiber. Swapping one restaurant meal a day for a konbini one can move the daily total by several hundred kcal.
