20
Q

Weaknesses of EI vs weight

A

Errors in measuring EE
Errors in estimating body comp
Unreliable

21
Q

What is indirect calorimetery

A

When foods are oxidised in the body O2 consumption and co2 production are proportional to heat generation

22
Q

What are the respiratory quotients for cho protein and fat

A

Cho - 1
Pro - 0.818
Fat - 0.696

23
Q

Why is the rq lower for fat

A

Because it contains more hydrogen and carbon atoms than oxygen

24
Q

A

Linerality between hr and O2 consumption

25
Q
