Female cutting advice

I'm trying to help my coworker lose weight by diet alone right now.

I'm having her track what she eats for a week and check her weight every morning just to get an idea of where she is at.

I've already noticed her diet is terrible and she has been eating less than I would recommend for a cut. I'm don't want to overload her with too much info so I'm starting with watching just daily calories for now and then picking better foods to get her macros right.

This is my first time helping a female so I'm just looking for advice on how to go about this. If anyone has experience in personal training and diet advice for females I'd like to here it.
