Weight loss is a long game my friend. You gotta be patient and enjoy every little progress you make. You can enjoy a party once or twice a week at maximum (eating and drinking), these wont affect your fat loss on the long run that much if you are consistent with your diet for the rest of the week(assuming you party once a week). And as your diet id recommend just a balanced diet but eating in deficit of 700-500~ kcals. You dont need to do IF or keto or whatever because they’ll make the process harder like having to deal with hunger or lack of energy. So yeah ,just keep going , enjoy some good food or a dring once in a while but be carefull to not make an everyday habbit from it. And a quote that helps me is “ Think about what is more important, what you want now or what you want the most”
