| Classification: Underweight | <18.5 |

| CLassification: Overweight | 25-29.9 BMI |

| _____________ increases the mortality rate from all causes. | Central Obesity |
| _____________ is energy expended at rest and during physical activity. | Energy Expenditure |
| Energy used to maintain life when the awake body is at complete rest, is ______________. | BMR (Basal Metabolic Rate) |
| CHO produces _Kcal/g; Protein produces _Kcal/g; Fat produces _Kcal/g; Alcohol produces _Kcal/g | 4;4;9;7 |
| Components & % of Energy Expenditure | BMR= 60-75% TEF= 5-10% Physical Activity Energy Cost= 15-35% |
| Thrifty Gene Theory | Proposes that gene causes people to expend less energy than other-leading to weight gain...energetically thrifty |
| Set-Point Theory | Proposes that each person's weight stays within small range...body compensates for changes in energy balance & keeps person's weight in this range |
| Leptin | Protein Hormone...Reduces Food Intake...feel FULL effect...less found in obese |
| Ghrelin | Protein hormone...stimulates appetite...Increases when hungry & decreases 1hr after eating...not diminished in obesity |
| Peptide YY (PYY) | Protein hormone...decreases appetite...released in GI tract...inhibit food intake |
| Orlistat | Decreases FAT absorption & inhibits pancreatic lipase:::Leaky stool; Abdominal pain; Flatulence; Fatty & loose stool; Decreased absorption of Fat Soluble nutrients |
