NUTR 120 Lecture 1: More for Nutrition 120 - Until Midterm 2
Document Summary
Kidney + heartbeat + respiration: bmr (basal metabolic rate): measurement of oxygen consumption and carbon dioxide release at rest, carried out after waking up, but before getting up. Hence the more a person has, the more energy a person requires to use/burn = Cellular processes (absorption) also take energy for metabolism. Metabolism: protein synthesis, fat formation, non-essential amino acids, glycogen formation, bmr (60%-70%); activity (15%-30%); thermogenesis (5%-10%, recommendation for energy intake, eer (estimated energy requirements): the average dietary energy intake (kcal/day) that maintains energy balance in a healthy person. When people finish growing, their weight remains relatively stable for long periods despite their changes in energy intake and output. Heavy set but fit: bmi does not address the issue of where the body fat is distributed, figuring out body fat distribution: measuring waist circumference. Women at risk if greater than or equal to 35 inches/88 cm.
