Building block: Explanations for the Success/Failure of Dieting
AO / IDA Content of paragraph
AO1 Dieting is dependent on regulating your food intake.
Memory is important for this within a meal and at subsequent meal.
Memory and If you don't remember eating, you have less control over what you eat as you
Dieting don't know the extent of your intake for that day.
AO2 Oldham-Cooper et al. ­ two conditions, one playing solitaire while eating
continuously and the other only eating.
Solitaire and Later offered biscuits. Those playing solitaire ate twice as many biscuits.
Biscuits Memory of the meal was not properly encoded, so had a vaguer memory of
what they ate. Consequently impacted later eating.
AO2 Polivy et al. ­ two conditions. Both offered unlimited sweets.
One condition ­ cleared wrappers away. Other ­ didn't.
Sweet If wrappers cleared away, ate twice as many sweets.
Wrappers The wrappers acted as a reminder, reducing further intake.
AO1 Case studies have shown that memory is more important than physical signals
of fullness.
Cognitive This can be controlled if you are reminded how much you have eaten.
Theory The memory can also be tricked in order to control intake.
AO2 Brunstrom et al. ­ gave participants a smoothie and asked to rate how full they
felt after.
Fruit Before ­ shown a plate of food and asked if they were allergic to any of it.
Smoothie Half were shown a small plate, the other a big plate.
After witnessing the big plate, felt fuller. Memory tricked about what they had
eaten, making their intake seem more than it was.
IRA Robinson et al. ­ developed a smartphone app.

Real Life ­ At each meal, you are reminded by the app of what you previously ate.
Smartphone Reminds you of what you've eaten, remind you of the fullness and reducing

milkshakes. Afterwards ­ unlimited access to ice cream.
Ice Cream No preload ­ non-dieters ate more.
and Preload of one ­ dieters and non-dieters ate similar amounts.
Milkshake Preload of two ­ dieters ate more than non-dieters.
Evidence of the `what the hell' effect ­ had already eaten more than intended
with the milkshakes, so carried on until reached satiety.

Here's a taster:

AO1 Herman and Polivy ­ why dieting may lead to overeating.
Hunger keeps intake of food above minimum.
Boundary Satiety keeps intake of food below maximum.
Model Dieters create an artificially low boundary for food intake.
(`What the Dieters tend to have larger range between hunger and satiety as takes them
longer to feel hungry and more food to satisfy them.…read more
