This is probably because your body has atrophied fat burning metabolic pathways. I would suggest to start with regular daily fasting. This means you eat within short window of time every day (max 4-6h) and the rest you get by with no calories. It takes about 2 weeks to a month for a person to adjust depending on your overall health, age and whether you are insulin resistant. Once you get adjusted, you can try to restrict carbs a bit. Carbs are responsible for most of the hunger feeling. When I cut carbs my hunger ended completely. Cutting carbs (with restricted eating window) will force your body to adjust to functioning on your fat stores alone. Please, be mindful none of this requires cutting calories. You can eat as much as you want, just keep your feeding to a short window every day and try restricting carbs and replace them mostly with fats. Ideally you would also want to pay attention to what kind of fats -- refined ones are usually the worst. Hunger is your body signalling inability to get fuel for its critical processes. Given that most of us have hundreds of thousands of calories of fat (even if you look relatively lean), it is a bit preposterous idea that should be understood by your body having large stores of fuel but being unable to access them when it needs. This might be because there is insulin present (any levels of insulin basically block your fat metabolism). Or it might be because you have never exercised your fat metabolism and now suddenly you require it to provide a lot of energy which it is not equipped to do. This is solved by simply exercising it which means allowing your body to metabolise your stomach content and then waiting some more so that it has to reverse its processes to start metabolising fats. 16-18 hours is what is necessary to get there and that's why 4-6 hour eating window comes from -- so that you can train your fat metabolism a bit, every day. With healthy fat metabolism you should be able to go on a prolonged fast and it should be enjoyable.
