1 six-inch sub (250 g) has about 580 calories.
Why estimates miss: Italian Sub is a multi-ingredient dish. Layered cured meats push the fat up, so skip the oil drizzle to lighten it. Generic calorie apps undercount the hidden oil, sauce and portion — CalDesk AI's photo estimate is tuned to catch exactly this.
