Calories and weight loss

I read that a calorie is a calorie is a calorie. 1000 calories of cookies is the same as 1000 calories from healthy options. It's still 1000 calories
BUT, it also said our bodies process calories differently depending on the source.
For example:
A slice of white bread and a slice of whole grain bread have about the same calories. But our bodies are more efficient at processing the whole grains compared the the refined grains of white bread.
Meaning that even though the same caloric intake is had, some could still lose weight due to the efficient processing of calories from healthy sources.
Does anyone know any more about this?

I'm not sure where this question is coming from and am afraid to weigh in in case this is coming from the place of an eating disorder since we're talking on an anxiety forum. But, I just did want to say that right now especially, the best thing to do is to focus on our overall health and healthy eating habits.

No eating disorder. I'm anxious about losing weight.
Can you eat the same amount of calories, but calories from healthy alternative that are processed efficiently by our bodies, and possibly still lose weight?
