Is 1000 calories of ice cream the same as 1000 calories in apples?

For example if I was on a CICO diet and I'm restricting to 1000 calories, would I still lose the same amount of weight if I ate unhealthy foods than if I ate healthy foods?

Yes. For the most part. There are functions of the body that might change based on WHAT you ate. For instance if you were lactose intolerant the numbers may be different, but for the purpose of calculating CICO the results would be the same. 

Just be prepared to be REALLY hungry all the time if you're eating calorie dense food.
