Document Summary
How eating patterns develop: normal development, developmental risk factor, biological regulators. Biological regulators: metabolic rate, serves to self-monitor and regulate behavior, body weight, growth, hypothalamus senses need to release growth hormone (gh) #1: eating is a natural process controlled by biorhythms that have adapted over time. Body weight: natural weight is regulated around his/her own set point, people who gain/lose weight will experience metabolic changes, strive to bring body back to set point, 90-95% of those who lose weight regain it w/in several years. Treatment and prevention: parents: take an activity role in children proper nutrition and activity level, schools: contribute to this e ort by educating kids in nutrition, exercise, and awareness of healthy eating attitudes and body image.
