Learning objectives:
• List the appropriate osideratios for ealuatig oe’s healthy body weight
• Discuss BMI as a measure of appropriate weight; advantages and disadvantages.
• Describe the set point theory of body weight regulation
• Explain energy balance
• Define the components of energy expenditure

What is a healthy body weight?
• Is appropriate for your age and physical development
• Is maintained without constant dieting
• Is based on family history of body shape and weight
• Promotes good eating habits and allows for regular physical activity
• Is acceptable to you
Evaluating body weight (BMI, body composition, fat distribution)
BMI (body mass index) = kg/m2
related to risk of chronic disease
lowest risk with BMI between 20 and 25
highest risk with BMI > 40
Desirable range (for low risk of chronic disease) women 21.3-22.1 and men 21.9-22.4
Underweight
Too little body fat to maintain health
Overweight
A moderate amount of excess body fat
Obese
An excess of body fat that adversely affects
health
Morbid obesity
Body weight exceeding 100% of normal - very
high risk for serious health consequences

Issues –
BMI does not take into account
Body composition
Fat distribution
A high BMI could lead to an incorrect interpretation of overfatness in relatively lean individuals with
excessive muscle mass.
Body fat distribution – apples and pears
Apple-shaped - upper body
Increased risk for chronic diseases
Pear-shaped - lower body
No significant increased risk for chronic diseases
Waist circumference - Waist girth reflects visceral adiposity and risk of chronic disease (cardiovascular
disease, type 2 diabetes, cancer)
High risk –
Waist circumference >40 inches men, > 35 inches women
Weight Control
Whether a person gains or loses weight depends on
– Genetic factors
– Childhood weight
– Lifestyle choices
– Energy Balance
Genetic factors
