MCQ for N/B Flashcards
What does Prentice and Jebb do?
Trend, EE has gone down, obesity is due to a reduction in physical activity
Pinel
Leaky barrel model of weight control. passive feedback and negative feedback (hormonal changes)
Mayer
Glucastatic model of hunger (set point model)
BUT glucose levels stay constant
Phallic phase response
release of insulin as anticapitory response
Wood hypoglyciemia
food cues, no food –> insulin released
wood hyperglycemia
food infused into stomach.. no pre-insulin released
Conditioned learning meal initiation
if CS+ paired with food.. CS+ group will consume more food
Satiety
the absence of hunger, period after meal before you get hungry again
Satietion
fullness during a meal
Cecil
Sensory stimulation important
soup, covert, overt
report hunger is reduced with eating soup and overt
Importance of sensory experience and congition
CCK cholecystokinin
Satiety hormone
Sham feeding causes…
over eating.. (food is not going into stomach) evidence from feedback
The pre-load meal paradigm Birch
Compensation
given soup with different k/cal contents
Children will compensate when given access to ad lib bufffet
-adults less good at this
Satiety hierarchy
P, C, F, ethanol
Cabananac
Alliestheia–> depends where you are, (if you had just had glucose, glucose will be less rewarding)
Rolls
Sensory specific satiety–> if you eat one food and offered another, will eat the other.. less likely if you are offered the same food
Berridge
Distinction between liking and wanting
- can manipulate this with use of psychopharmological drugs
- can have liking without wanting–> FI decreases + pleasantness, limited effect in hunger
- or vice-versa, pre-meal hunger decreases, little effect on pleasantness and sweetness
effects of bottomless bowl
if the soup keeps filling up, ppts will say they are full ne, effect of external cues
portion size
the greater the portion size the more you will eat BUT is found to be effected by if foods are energy dense
Mindless eating –> distraction
if you are distracted you will eat more: mental imagery, gaming
memory for food
primed to think of your lunch you will eat less snacks
-episodic memory plays a role in appetite regulation
Amnesics
they will keep eating, experinece of fullness but cannot associate what the feeling is.. so keep eating
The name of eating episode
snack or meal has an effect on how much you will consume after
smoothies no. of fruit
if told that the smoothie had more fruit in, greater experinece of fullness
Distraction–> disrupting memory, manipulating memory quality
if you watch TV at lunch, (distracted) you will eat more snacks later on..
Focusing on eating
focus on food during lunch, reduced FI at snacks later on
Social influence on eating
the number of people present postively correlated with meal size
eating topography
ID in the way people consume food, eg. chewing, bitesize, time taken, etc.
2 main measures of eating topography
- videoing eating (coding different behaviours)
2. hidden balance scale
oral stimulations vs gastric volume, what fullness depends on?
2 levels of OS and 2 levels of GV
-> greater levels of OS predicted reduced FI
Fletcherism
chewing your food is good for you 50-100 times to aid digestions
eating faster means associated with being..
obese
Training people to eat slower… use an instrument called a..
mandometer… leads to significant and sustained reduction in BMI
effect of texture of food on eating rate
eating an apple compared to apple juice, or soup suppressed hunger more
–> oral sensory exposure is important
time in mouth reflect perceived fullness
effect of viscosity on food intake
if it is more thick, so solid food compared to liquids reduced food intake (longer in mouth)
Number of chews on FI? (smit)
the more chews the less food eaten
number of bites on FI?
slowing bite rate, reduces energy intake
bigger bits sizes equate to greater energy intake
pausing and palatibility
intro of pauses within meal enhanace intake aswell (due to effects of palatability) bit counter intuitive
being a decelerated or linear eaters?
linear eaters can eat more, eat more at higher rate
eating rates are different across different foods
when food can be ingested rapidly, food and energy intake is high. ppts are more at risk of overconsumption
impact of hard foods and soft foods?
hard foods led to reduce EI compared to soft foods
is portion size assocated with visual cues??
no difference, seems to be influenced by bitesizes
The omnivores paradox
need to identfy harmful or beneficial food, resources a major driving force for a cognitive revolution
Problem with basic reactions to taste
insuffient to explain all our food choices by this, we have amazing ability to discriminate
Pavlov
models of associative learning
eye-blink conditioning has..
close temporal contiguity
Conditioned taste aversion, Garcia
Rats are hard to kill, will learn avoidance for harmful foods, this will persist 24 hours
Can CTA occur after a single exposure?
Yes, gorgonzola
What are the limitations of the CTA?
they have to be particular things to become associated, you cannot condition sickness with a noise for example
Flavour consquence learning in animals, Scalfarni
dev flavour preference, infuse into stomach either nutrients or water develop preference for CS+
Flavour consquence learning in humans
2 novel flavours, manipulate ED, –> results are not as conclusive as animal studies
