Have you ever discovered you made a food calculation error?

I could not figure out why my tomato yogurt made me so hungry and then I discovered a medium tomato is only 22 calories. I was using smaller tomatoes which might have been 18 calories. I usually use a higher calorie fruit with yogurt and that is a lot better at getting rid of hunger between meals. Sometimes my yogurt keeps me so full I have to skip dinner.
