1. Simple, it is very hard to overeat when you are eating nutrient dense foods. Eat a bunch of empty calories and your body will still be hungry because of the lack of nutrients.

2. Will you eventually lose weight through limiting “calories in” aka calorie restriction? Yes, but now you are fighting “calories out” by decreasing metabolism depending on how much of a deficit you go on. Calories out depends on a lot of factors and you cannot just change calories in. The body is complex.
