The regulation of feeding drive and our motivation to eat was discussed. Two basic theories: glucostatic and lipostatic and other theories i.e. reinforcement and reward circuits were presented. The Author presented basic information about energy intake and its expenditure. The interest was focused on fat tissue as an endocrine organ. The cross talk between brain and gastrointestinal tract (brain-gut axis) was discussed in terms of neuroendocrine and hormonal regulation. The mechanisms of short and long-term appetite regulation were shown including ileal-brake mechanism. Some hormonal defects which lead to obesity as well drugs action to influence appetite was presented. The role of endogenous cannabinoids system and further perspectives in feeding regulation were closed up. Changes in the gastrointestinal tract associated with starvation were discussed. The impact of ageing on feeding behavior, appetite and related hormonal regulation in humans and animals was presented in details.
