cue that may encourage a behavior (EX: Tv commercial of fast food)
ghrelin
Give this one a try later!
Peptide hormone produced in the stomach; Stimulates food intake prior to
meals; Levels are elevated for 1 -2 hours prior to a meal, then decreases
once the meal is consumed.
,Physical activity contributing to increases in obesity in America
Give this one a try later!
Americans exercising less; modern transportation; increased sedentary
lifestyle and screen time
Gallbladder disease associated with excess fat
Give this one a try later!
Gallstones (cholesterol clusters) accumulate in the bile duct of gallbladder
Bile duct blockage: Impaired lipid absorption in the small intestine (painful
and potential removal of gallbladder)
Obesity genes
Give this one a try later!
Genes involved in regulating body fat
Code for proteins involved in the regulation of food intake, energy
expenditure, or deposition of body fat
If abnormal, the result is abnormal amounts of body fat
Dilution methods for assessing body composition
, Give this one a try later!
Injection of water-soluble isotope in the blood stream mixing with the
water in the body; Isotope concentration in body fluid is measured to
determine amount of lean body tissue and body fat.
Drawbacks: Expensive and invasive
How to calculate total energy
Give this one a try later!
Total energy (kcal) = (kcals carbs) + (kcal fat) + (kcal protein) + (kcal alcohol)
indirect calorimetry
Give this one a try later!
Estimates energy use by assessing oxygen utilization.
Subject breathes into a mouthpiece, mask, or ventilated hood.
Production of CO2 and oxygen is measured and thus body's energy is
calculated
adaptive thermogenesis
