Hedonic impact7/26/2023 ![]() ![]() (“I like eggs.”) However, in the scientific literature, “liking” refers only to our actual reactions of pleasure, both conscious and unconscious- the hedonic impact of an experience. When we speak of “liking” something, we’re consciously predicting our future reactions. Though the terms “liking” and “wanting” seem reasonably self-explanatory, we must be careful when using them in the scientific sense. Defining Our Terms: “Liking” = Hedonic Impact, “Wanting” = Incentive Salience Therefore, I will briefly summarize the current state of scientific knowledge, as I understand it, on the subject of hunger and reward. When, after innumerable posts and presentations on the subject, we see very smart people unable to articulate exactly what is meant by fundamental concepts like “palatability”, it’s quite likely that the hypothesis in question is poorly specified. That being said: let’s get started! Endless Arguments Are Often A Sign Of Murky Definitions The current literature is both comprehensive and, I believe, more than adequate to explain and understand observed phenomena. Please note that I have no horse in any of the current races: I am neither selling diet books nor defending a career-building hypothesis, and my current series of articles started long before the AHS and any still-simmering disputes.įinally, and most importantly, I am not proposing any new theories of hunger or obesity. (An aside: I thank you, my readers, for continuing to provide references, intriguing leads, and constructive criticism. My objective with the articles I write here at is to organize, distill, and summarize the bewildering variety of nutritional information into succinct, helpful articles, to share them with my readers, and to improve them as new information comes to my attention. I’ve put off writing these next few articles because they’re likely to cause some controversy, which I don’t enjoy. Some common enablers are eating quickly, eating while distracted or on the run, and eating calorie-dense packaged and prepared foods. We can also bypass satiation by decreasing sensory exposure to our foods. As with satiety, we fail to achieve it by not satisfying our nutritional needs. Satiation is an estimate of future satiety based on sensory input.We fail to achieve satiety by not ingesting (or not absorbing) the energy and/or nutrients our body requires, and by an inability to retrieve the energy and/or nutrients our bodies have stored due to mitochondrial dysfunction. A lack of satiety will leave us hungry no matter what else we do to compensate.Therefore, a successful diet must minimize the role of willpower. Restrained eating requires the exercise of willpower to override likes, wants, and the lack of satiation or satiety the exercise of willpower uses energy and causes stress and stress makes you eat more.In a properly functioning human animal, likes and wants coincide satiation is an accurate predictor of satiety and the combination of hunger signals (likes and wants) and satisfaction signals (satiation and satiety) results in energy and nutrient balance at a healthy weight and body composition.Hunger is not a singular motivation: it is the interaction of several different clinically measurable, provably distinct mental and physical processes.In previous installments, we’ve established the following: Go back to Part I, Part II, Part III, Part IV, or Part V-or go on to Part VII.)
