The obese state is associated with altered reward functions, but it is not clear whether these changes are the cause or consequence of obesity. In hedonic hunger, presently due to highly availability of cheap, energy dense and palatable foods, it activates reward system in which sensory signals activate insula, when someone tastes opioids release from endocannobiniods, that activates mesolimibical system in brain that activates the neurotransmitter dopamine in ventral tegmental area to communicate with neurons in nucleus accumbens in order to elevate reward system and motivate to increase food intake. Then information regarding food intake will pass to second order neuron (incharge of receiving information regarding food intake from AN) - paraventicular nucleus and lateral hypothalamus these signals further project into nucleus tractus solitary (brain stem), this then triggers ghrelin through vagus nerve to increase food intake and maintain homeostasis. It contains agouti-related peptide (appetite activators) and pro –opiomelanocortin neuron (appetite inhibitor. In hypothalamus signals are received by neurons, i.e., accurate nucleus it’s a first order neuron it regulates appetite since peripheral adiposity factors act directly on these neurons. When a person is hungry, stomach increases the production of ghrelin and decreases leptin produced by adipose tissue, which indicates weight loss and signals hypothalamus to increase food intake. Hedonic and metabolic consequences are interdependent in that the hedonic value of food modulates caloric intake, and the metabolic status modulates hedonic processing. The metabolic consequences of food are regulated by homeostatic functions and the hedonic consequences by reward functions. Likewise people with hedonic hunger experience frequent thoughts, feelings and urges about food in absence of energy deficiency.Ĭentral and peripheral mechanism involved in maintenance of body homeostasis. As substance users/gamblers are pre-occupied with their habits even, when they are not engaging in it. Hedonic hunger is equal to substance use/gambling. Hedonic eating is more prevalent in women, when compared to men (Ewoldtet al., 2015). Hedonic hunger is defined as the driver to consume highly palatable foods in the absence of physiological need for calories/ energy deprivation.
