Do you suffer from allergies/chronic rhinitis by any chance? I have hyposmia because of rhinitis. But I get the same - go without food for a while and my sense of smell increases until I eat and become satiated. Now whether it’s related to certain allergens that I eat or the body/senses becoming less sharp I do not know. Probably worth investigating a bit more, I never really dug deeper into this.
