weight management and energy balance Flashcards
each of the following factors can have an impact on weight loss program adherence or success
social, economic, physiological, psychological, emotional
social settings can create major obstacles to weight loss due to
pressure to eat when calories are not needed
obstacles to weight loss
over consumption
large portions
boredom/social eating
location eating
pressure to try food
multiple/large dishes at restaurants
not knowing caloric densities
throwing out restrictive habits
alcohol
peer pressure
___ calorie ___ cost foods have become a staple of many American diets
high, low
food desserts
lack fresh healthy food options, reflect areas with impoverished population segments where the risk is intensified
___ is the primary physiological determinant for eating behaviors
hunger
hunger is stimulated by
hypothalamus
hunger stems from the
physiological need to eat based on body signals
hunger is feeling that
does not indicate exact caloric need
satiation is experienced when
the body indicates it has consumed enough food, shutting off the hunger response
ignoring hunger can result in
heightened psychological perception of energy needs termed appetite, which usually results in overeating
the psychological pleasure of eating contributes to
calorically dense diets
people find pleasure in taste, texture and sensations associated with
certain food or environments
_____ foods rich in ____, ___ and ____ have the most desirable tastes and therefore present major problems in a diet aimed at weight loss
high calorie, fat, sugar, salt
psychological considerations can also include
behavioral patterns
environmental cues
learned eating behaviors
perception of the monetary value o food
learned eating behaviors include
eating everything on the plate regardless of hunger, eating patterns learned from parents/family and cultural habits
______ can drive people to eat when they are not hungry, such as
certain emotions or mental states
stress, sadness, loneliness or boredom
when individuals routinely consume food excess of the body’s caloric requirements,
energy balance becomes uneven
energy balance=
calories consumed vs calories expended
calories consumed > expended
potential weight gain from positive caloric balance
calories expended > consumed
potential weight loss from negative caloric balance
calories consumed=expended
weight should remain unchanged, isocaloric balance
significant caloric restriction causes
weight loss
significant caloric restriction weight loss results from
water and lean mass reductions, especially with inadequate protein intake and aerobic exercise
cutting calories below what is needed for the ___ causes the ____ to create strong signals to consume food
RMR, hypothalamus
RMR
the energy required to supply bodily functions during resting conditions
for severely obese individuals, some physicians may prescribe
very low calorie diets
VLCD
contain 800-1200 kcals/day
VLCD should only be prescribed by
medical doctor and require closely-monitored food selections for nutrient density
