Dear Noks
The subjects of what influences human appetite is so big that I would have to write you pages and pages about it. One of the major factors is blood sugar level. When your blood sugar level drops, you generally feel hungry and vice versa. In addition there are many, many different hormone-like substances that researchers have identified that seem to play a role. Then there is the psychological effect - humans tend to be 'programme' to eat at certain times of the day, or because they regard food as a comfort. The appetite and the immune system are not really linked, except that if your appetite is suppressed and you don't eat a balanced diet then your immune system may also get depressed. The links between appetite and metabolism are also so varied that I can only give you an example: if you have a suppressed metabolism as occurs when you produce insufficient thyroid hormone, then your appetite may be suppressed and vice versa.
Hope this helps
