Classification: Underweight | <18.5 |
Classification: Normal | 18.5-24.9 |
CLassification: Overweight | 25-29.9 BMI |

Most Accurate body composition measurement method is _______________. | Dual-Energy x-ray Absorptiometry (DEXA) |
______________ is a valuable indicator of fat distribution and central obesity. | Waist-to-Hip Ratio |
_____________ 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 |
Sibutramine | Decreases appetite by altering brain nuerotransmitters:::Increased BP; Constipation; Anorexia; Nausea; Dry mouth; Insomnia; Dizziness |
