Sugar is not just empty calories. Your muscles need glycogen, which is produced from carbohydrates—including sugar—to function.

Simple sugars are particularly effective at restoring glycogen stores after intense cardiovascular workouts.

It seems you may not know what the phrase "empty calories" means, so, let me help: https://en.wikipedia.org/wiki/Empty_calories

Lumping simple sugar in with complex carbohydrates as equally beneficial because they're both carbohydrate molecules is horrendous prevarication. And bringing up "intense workouts" at all, which I'm sure you very well know is demographically an extreme outlier scenario, in a conversation about weight gain, is the most hilarious kind of derailment.
