Does modafinil cause weight loss?

My friend takes modafinil for a medical condition and she mentioned she lost some weight since starting it. I'm trying to lose weight too, and was curious. Does modafinil cause weight loss?

Yes, it basically turns off your appetite sensor! You'll be so busy working that you will look at your watch and realize you missed lunch entirely.

It can cause some weight loss because it reduces appetite, but if you have hormone issues like thyroid, sudden weight changes should always be discussed with your doctor.

Since it reduces hunger, make sure your blood sugar levels don't drop too low. If you skip meals, it can be risky, so eat small snacks at regular intervals.

Please be careful. I once ignored rapid weight loss from a medication thinking it was great, but it messed up my system. Do get your vitals checked regularly.

I lost a couple of kilos initially and got super worried, but it stabilized once my body got used to the medication. Just ensure you eat healthy portions.

In my experience, medications that increase alertness often speed up your system slightly and reduce appetite, leading to mild weight loss. It is nothing to fear as long as you eat balanced food.

I was reading about this online and yes, many people report losing weight because it acts like a stimulant and keeps you too focused to feel hungry.
