    Study Notes

    Controlling Food Intake: Hunger, Satiety, and Appetite

    • Food taboos are present in all cultures and serve as a powerful means of controlling dietary choices.
    • The study of what controls eating is crucial for promoting healthy eating, managing obesity, eating disorders, and understanding food intake regulation.
    • Hunger has both subjective (psychological) and objective (nutrient-depleted state) meanings, leading to varied sensations and desires to eat.
    • Satiation is the loss of desire for food during an eating bout, with both subjective and objective meanings, while satiety refers to the absence of hunger and the physiological state after a meal.
    • Objective measures such as amount consumed, eating rate, and food types selected are more reliable than subjective reports of hunger in experimental studies of humans.
    • Food intake can be driven by hunger or satiety, and both short-term and long-term energy needs must be considered in controlling eating.
    • The control of eating is complex, involving biological and psychological factors, and there are three recurring themes: biological controls of appetite, psychological controls of appetite, and central versus peripheral controls.
    • Stomach contractions historically represented hunger, prompting eating, and stopping when the stomach is filled, but the direct causation of hunger by stomach contractions is questioned.
    • The study of food intake regulation is essential for understanding obesity, eating disorders, and promoting healthy eating.
    • Both subjective and objective measures are used in experimental studies to understand hunger, satiety, and food intake regulation.
    • The study of food intake regulation involves biological and psychological factors, and the interplay between hunger, satiety, and appetite is complex.
    • Understanding the control of food intake is important for addressing public health issues such as obesity and eating disorders, and for promoting healthy eating behaviors.

    Peripheral Factors Influencing Food Intake

    • Portion size significantly influences food intake unconsciously, and smaller plates at home can reduce intake.
    • Larger food packets lead to larger serves, and portion sizes have increased in recent years.
    • The greater the variety of foods available, the more one will typically eat due to sensory specific satiety and more choice.
    • Making food more accessible increases consumption, and people tend to eat more if no extra effort is needed to obtain the food.
    • Time serves as a cue to eating, with meal times changing historically and driven by artificial light and work requirements.
    • Evidence suggests that meal sizes increase and inter-meal intervals decrease across the course of a day in American participants.
    • Ambient temperature and temperature regulation have been suggested to affect appetite, with body temperature drops increasing hunger.
    • Food consumption consistently increases in the fall, possibly due to the drop in ambient temperature or shortening days.
    • The number of people present when eating consistently promotes food intake, with more people leading to more food consumed per person.
    • Social facilitation effects are most pronounced for family members and friends, and occur for any type of meal or snack.
    • Television viewing can increase food intake via the same mechanisms as for social facilitation, and the effects are most pronounced if the TV show is moderately distracting.
    • TV viewing can trigger eating via associative learning, and just sitting and watching TV can trigger eating.
