Even then it's still a lot of food.  A Big Mac, often the symbol of gluttony, is 550 calories.  Someone with a slightly above average TDEE (2500-2700) could eat about 5 of them per day and still only gain weight very slowly. That's a Big Mac for breakfast, TWO for lunch and TWO for dinner.  And you need to eat significantly more than that in order to gain weight at the rate these things do.
