How long have you been doing the keto thing? Bear in mind, despite its popular adoption, it's a drastic diet and not healthy to sustain for too long.
As someone that occasionally cut weight through keto, I remember the feeling of craving pastry and giving in to cheat days. It's very effective, but not sustainable over long stretches - and certainly not a good lifestyle choice.
Maybe it's time you start to transition to a sustainable long term diet - fruits, greens, nuts, oats, preferred protein sources in reasonable daily portions. It doesn't mean not eating burgers, chips and ice-cream - there's good nutrition in there too - just try to keep that sort of thing to the weekend.
EDIT: Consider starting the weight training you mentioned as well. Not only is it important to maintain your physical health, it's key in maintaining your mental faculties into old age as well.
