Causes of Obesity
Genetics and weight
Lipoprotein lipase (LPL) - promotes fat storage
Leptin - hormone secreted by fat cells
Ghrelin - hormone (released by stomach cells) that makes the body want to eat
Hunger vs appetite
hunger = physical need to eat
appetite = psychological desire to eat
Satiation vs satiety
Satiation = feeling of no longer being hungry
Satiety = sustains fullness until next meal, inhibits the body feeling hungry
Lipoprotein lipase (LPL)
Cell surface enzyme that hydrolyzes triglycerides and promotes fat storage
Higher LPL activity in obese people
