NCMA 215 -- weight management and nutri education and counceling

Anorexia nervosa

— Extreme weight loss from strict dieting, over‑exercise, or starvation

— Distorted body image: feels “never thin enough” despite severe weight loss

Bulimia Nervosa

— Pattern: binge eating → purging (vomiting, laxatives, fasting, or over‑exercise)

— Key features: episodes of large intake + behaviors to “compensate”

Health Belief Model

— Explains and predicts health behaviors based on what a person believes about the problem and the action needed

— Core assumption: people take action if they value health and are willing to participate

Self‑Efficacy Theory (Bandura, 1997)

— Centers on a person’s belief: “I can do this specific task” — this belief comes before expecting results

Theory of Reasoned Action / Theory of Planned Behavior

— Core idea: behavior follows intention, and intention depends on:

— Attitudes — positive or negative feelings toward the action

— Subjective norms — what you think others expect or do

— Focuses on how people interpret and act on their own attitudes and social pressures
