1

Explain the law of thermodynamics

Clients wanting to lose weight must burn more than they consume.
Clients wanting to gain must consume more than they burn
Clients wanting to stay the same need to consume the same amt of calories they burn off

2

PT scope of practice when it comes to nutrition

Refer clients w/ health issues to physicians
No written diets

Can provide:
food prep
Healthy snacks
statistical data
vit and min as essential nutrients
Food guidance systems (My plate)
Carb protein and fat basics
nutrients contained in food or supps
Importance of water and hydration status

3

Unit of expression of energy equal to 1,000 calorie
Amount of heat energy required to raise the temp of 1 kilogram or liter of water 1 degrees Celsius

Kilocalorie

4

Calories tell us what?

How much energy is contained in food

5

Calorie of Carbs, Fats, Protein, and Alcohol

4,9,4,7

6

Amount of energy spent on average, in a typical day

TEE

7

TEE Total Ennergy expenditure is found by including these 3 things

RMR
TEF
Physical activity

8

Amount of energy expended at rest; account for 70%

RMR

9

Amnt of energy expended above RMR as a result of the processing of food for storage or use

Thermic effect of Food (TEF)

10

How much does TEF account for

6-10%

11

Amount of energy expended above RMR and TEF

Physical activity

12

How much does physical activity account for in a sedentary person

20%

13

Factors that affect RMR

Age, sex, genes, body comp, meds, smoking, etc

14

Builds and repairs body tissue

Protein

15

What are proteins made up of

Amino Acides

16

How many essential and non essential amino acids

20 total
8 essential

17

Explain diff b/w essential and non essential acid

Essential: must get from our diet
Non essential: Can make within body

18

Protein has to be broken down into what before it can be absorbed. Explain the process

Amino Acids
Protein via mouth
Stomach:Protein is denatured (broken down) into smaller peptide chains
Intestines: Break peptides into amino acids that can be absorbed in to the bloodstream, (TRI, DIP AMINO)
Bloodstream: body uses the amino acids to build muscle , convert into energy if needed (Gluconeogenesis), or if excess of calories will be stored as fat.

19

Protein sources come in two forms

Complete and Incomplete

20

Define and give an example of a complete protein

Contains all essential amino acids, Meats and diary products

21

Define and give example of an incomplete protein

Low or lacking essential amino acids. Peanut butter

22

What is the limiting factor

Amino acid missing in the smallest amounts. Lac

23

Food lacking amino acid that is not combined with a source high enough in the missing amino acid

the body will only be able to synthesize protein until the limiting amino acid runs out

24

Requirements for protein increase when

Exercise and when overall energy intake (calories) decrease. This way it will be used as energy

25

Excess calories protein will be stored as what

fat

26

Adequate carb levels spare protein for

tissue building and repair

27

What % of protein should account for overall calories

10-35%

28

What else does protein provide, especially in a deficit

satiety

29

Very high protein about 35% is not recommend, what are the reason

higher intake of saturated fat
low fiber intake
decreased glyocogen stores
increased urea production
Dehydration

30

What is the recommended protein intake for a sedentary adult

0.8kg/lb or 0.4 g/ lb
