<human>:  Can you tell me the calorie count for a standard cheese burger?
<bot>: Sure. I believe that a cheese burger with tomato, lettuce, and onions on a bun will have approximately 260 calories, and that a cheese burger with tomato and lettuce on a plain bun will have approximately 270 calories. I would recommend eating this snack only if you have no plans for the rest of the day, as I believe it will be of no benefit to you.
