If a man has a hormonal imbalance from a blood test, can he make dua for Allah to cure him without him losing weight or changing his diet? He is overweight and eats junkfood, doctor says he should lose weight and change diet to help fix this since they contribute to the imbalance, but can the man make dua and not change his lifestyle? He wants to make dua Allah makes his hormones the same like any other overweight man who eats junkfood and not different or worse so that he specifically has to do these changes, is this permissible? This makes him depressed and he just wants to make dua like in this fatwa from your website https://www.islamweb.net/amp/en/fatwa/132693/

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

A Muslim should employ the causes or means that eventually lead him to achieve his desired goals and meanwhile award off any fear. Supplication is undoubtedly one of the most important of these means. Thus if he exclusively restricts himself to it, this would be permissible, but it would be better if he employs all means, be they corporeal or incorporeal. Thus he has to make supplication to Allah, the Almighty, and then has to act according to the advice of the doctor, meanwhile entrusting all his affairs to Allah, the Almighty since nothing can benefit man except with His permission and support.

Allah knows best.
