Document Summary
Metabolism: process through which living systems acquire and utilize the free energy they need to carry out their various functions. Meta: change, transformation lism: study => the process by which food is transformed to provide energy. In balance when: energy intake (food and drink) = energy expenditure (smrs, activities, exercise) Smr: standard metabolic rate = metabolic rate (rate of all metabolic reactions) of an organism not digesting food at thermoneutrality under resting and stress free conditions. When energy expenditure (smr, activities, exercise) > energy intake (food) : anorexia, cachexia (severe chronic illness, conditions seen in cancer patients), death. When energy intake (food) > energy expenditure (smr, activities, exercise) Weight gain, obesity, type 2 diabetes, death, metabolic syndrome (hypertension and weight gain that lead to heart and liver diseases) 1985: a lot of states with no data 1991: a little bit around 15-19% bim. Observation: steep increase in obesity over the years.
