Talk to her privately, she may be going through a tough time at the moment, ask her why she thinks she believes she needs to loose weight.
If she does need to lose weight, due to this person having a higher weight scale. ( If she is over weight only! ) Tell her fasting is not the best of an idea, ask her to go for a walk, go to the gym, say something like '' Yeah! I've been meaning to go myself, I'd love you have you accompany me! '' .
This is what I would say!
I believe astrology is an outdated system and can no longer be relied upon. The pseudoscience depends upon spiritual figures which hold no explanation for why it can answer questions.
