Q&A: Will you still lose weight if you eat really small portions of unhealthy foods?

Question by ♥Sister of Sirius♥ : Will you still lose weight if you eat really small portions of unhealthy foods?
So my best guy friend eats like nothing, but when he does eat, it's unhealthy food. Like at lunch, he would eat maybe a chocolate chip cookie and a Snapple. He also does no sports and does not exercise. Yet he is only 110 pounds. I, on the other hand, eat more, but healthier. I also run for about 30 minutes a day.And then at night, I do crunches and leg lifts for 30 minutes.
