chapter 10 Flashcards
energ itnake
energy we get by eating food and to survve and thrive
energy
ablitiy to do wrok
energy expenditue
fuel for basal meabloci , physical activity food processing
energy balance
expenditure = intakae
energy intake sources
energy intake sources are 3 energy yieling nutirens carb lipid protein , cellular respiration brek bonds and atp found , alchol provides eenrgy but not nutirent
energy expenditure
basal maetbalic rate , basic energy life sustainign functin over time , breathing , heatbeat ,60-70 % energy we burn
fast metabloism
they burn calories to sustain bdy even beore physicla actiity
low metablism
expnd fewer calories on life sustaining pocess , ahrder time achieving energy balance need to consume fewer calorie or burn more to achieve balance
bmr factors
lean body mass msot important . geneics , age , height . gender ,
diet induced thermogenesis
danmic effect , thermic effect it accounts for 10 %energ ependiture , more energy is needed to process protein , les for lipids , fat lower thermic effect
physical activity
element energy expenditure is nde rcontrol is physicala ctivty , voluntary movemnts expenditure of calories ,
energy balance
hnumber calories from carb lipid protein matches the energy we exmed from bmr diet induced and physcial activity
increase body weight
increase in adipocytes cells
energy storage
whiel most of energy is stored as carbs and glycogen , most i stored as fat aadipocytes cell , adipocytes empty looking they contain , triglycrides and fatty aacids
energy retrivial
energy deficit when consume less energy tha our bodies need to perform functions to meet requirments ,
what happens in energy deficit
glycogen wil turn into glucose and body proteins will beused fo r aminaocids metbalozied from atp . most energyr etrival omes from afipocytes , if constanly calori eficit adipocytes become smaller and smaller and lose ft and wright loss , prtiens also lean body amss
weight gain
lean mss increase muscle mass , fat mass imcrease glycogen storage water fluctate increase more cell more voloume for warer , larger people maye ore likely to see shits water wights form day to dya
weight loss
lsoe lean mass , muslce mass decrease , energy decrease with age , water losses , fad dies promtoe water loss , gained back quicky , loss eergy stored as fat , for every 10 kg body fat 1.6 kg water and 8.4 carbon dixoide from lungs through energy or heat
obesity
hormone leptin , ecreate by adipocytes comunicaies with brain m promote fullness and energy expeniture promote energy balance , adipokines messenger m communitace tissues maintain hoemstasis
below certian levela fat mass adipokiones
poduc ehelath promoting effect dcrease inflmaitiom
obesity chronic diesase
excess fats tored in body , long term , sytematic approach , body structure affct and fnctiom , sick fat diseas and fat mass disease
sick aft disease
lwo grade infalmtion
fat amss disease
weight places on boddy , qualiy life neagtive effect
geentics and body size
good chance resmebl gentics , poleygentic
complex cause of oebsity
social psycology , physiology , inidviudal psycology , indiviudal phsyial activity , food onsomption , foodproduction , physoal anevuronmn
