lecture 17-18 - Energy + Obesity Flashcards
1
Q
Energy Balance
A
Energy = Energy in (food and beverages we eat) - Energy out (heatlost, radiant and evaporation) (Adults should try be in energy balance so weight is stable)
2
Q
Energy in
A
Food & Beverages (Metabolisable energy = energy from food & beverage -energy lost in faeces)
3
Q
Energy out
A
Resting energy expenditure, thermic effect of food, physical activity, growth
4
Q
Positive energy balance
A
Energy in > Energy out (Growth/Weight gain)
5
Q
Negative energy balance
A
Energy out > Energy in (Slowed growth in kids / Weightloss)
6
Q
Basal Metabolic rate vs Resting energy expenditure
A
Both Energy expended at rest, energy expended to fulfil life-sustaining functions. BMR requires strict conditions to measure REE doesn’t
