Hedonic hunger: eating for desire and not calories

Abstract

Hedonic hunger can be described as a state where an individualexperiences recurrent feelings, thoughts, and desires about foodin the absence of energy deprivation. Living in an obesogenicenvironment where cheap, tasty foods are available in plentifulamounts is one of the major causes of hedonic hunger development.Hedonic hunger can be analyzed using a power of foodscale (PFS) which estimates appetite and not palatable food consumption.The current epidemic of obesity globally (termed as“globesity” by WHO) is seen to be majorly driven by the hedoniceating system and an imbalance in the energy homeostasis system.Previous studies indicate that hedonic hunger and obesityare associated, and a weak but no significant correlation existsbetween BMI and PFS score. It can lead to the development ofvarious lifestyle disorders in the longer run. High levels of pleasure-driven hunger can even lead to detrimental health outcomeslike poor glycaemic control, unhealthy dietary behavior,and increased lipid profile levels which are aggravated explicitlyin cardiovascular diseases. With the adaptation to western dietarylifestyle, people are keener to opt for food options that canbe damaging and harmful when low levels of self-control, dietarymotivation, and healthy dietary habits are absent. Apart from thereward regulation system, which has a direct effect on hedonichunger, certain external factors like emotional eating, meals andmeal preparation, food cravings, sleep, physical activity, stress,social media, portion size, peer influence, an atmosphere of arestaurant can also promote more than required intake of food.This review article summarizes the above findings taking into accountthe plethora of research studies conducted so far.
