1

Energy intake is

Caloric intake that we get from out diet

2

Energy output or expenditure is?

Caloric output
• Basal metabolic rate
• Thermic effect of digestion
• Daily activity
• Exercise

3

Intake =

Output (Expenditure)
• Caloric Balance
• Maintain weight
• If body weight does not change over the course of several days or weeks, there is caloric balance

4

Intake > Output means

• Positive Caloric State
• Gain weight

5

Output > Intake means

• Negative Caloric State
• Lose weight

6

Weight Management: What are both sides of the equation?

• Caloric Intake; adjust the diet & ingest fewer calories
• Caloric output; Get enough physical activity, increase daily activity, exercise causes positive adaptations to the cells

7

Body weight provides a?

Rough estimate of energy state

8

Normal weight is?

Average weight for a given height

9

Overweight is?

More than average body weight from muscle, fat, or water

10

Underweight is?

Less than average body weight from muscle, fat, or water

11

Obesity is?

Having excess body fat

12

• Most commonly used measurement in clinical and research settings
• Does NOT actually measure fat
• Strong bias (error) in muscular individuals
• Moderately related to the best method (hydrostatic
weighing) for measuring fat (r = .71)

Body Mass Index

13

BMI =
• It is a ratio of?
• Does not indicate what the?

body mass (kg) / Height (m2)
• weight per unit height
• body is made up of

14

40=

40 Extreme Obesity

15

Used to study relationship between body size (_____) and risk of disease (_________) and early death (_______).

Body size=BMI
Risk of disease= morbidity
Early death= mortality

16

Research by the CDC shows that Underweight or Obese
increases risk of?

disease and early death

17

Overweight does not increase risk, infact they are at lower risk than those in the “normal” category
