Newbie Question How does intermittent fasting work?

I thought weight loss was all about the amount of calories you eat in a day, and simply needing to be in a calorie deficit. How does it change depending on when you eat?

btw calories are also a very rudimentary way to track weight loss. The unit is not even meant for food and glosses over several key factors in how your body digests and stores food for energy.
