Supplements

Question 1

What are fat burner supplements

Answer 1

Claim to increase fat metabolism, energy expenditure, impairs fat absorption, prevent weight gain after weight loss, weight loss, suppressed appetite, increase fat oxidation during exercise and cause long-term adaptations that promote fat metabolism

Question 2

Different types?

Answer 2

Metabolism booster
Appetite suppressant
Absorption blocker
Altering nutrient partitioning

Question 3

What is Metabolism booster

Answer 3

Burns more calories
Stimulate metabolism through activation of sympathetic nervous system
Rises Resting energy expenditure

Question 4

Exampl of Metabolism booster

Answer 4

Caffeine
Increases FA oxidation, mobilises fat, thermogenic effect that increases basal metabolic rate, hydroxycut, increased lipolysis rate

Causes anxiety, insomnia, jitters, irritability and nausea (Tolerance can be built up.)

Efficacy -> shown to improve performance with limited dosage (Not effective long term)

Question 5

Appetite suppressant

Answer 5

Calorie blocker => takes in less calories
Lowers effect of ghrelin (decreased release)
Effects brain -> believes its full
Absorbed water to increase satiety
CCK is released when bloated

Question 6

Example of Appetite suppressant

Answer 6

Fibres
Produce short FA chains => increases satiety
Increase secretion of satiety hormones through bacteria in gut
It can absorb water to enlarge in stomach

Only small weight loss in 2 weeks not effective

Causes bloating, upsetting of GI tract and hormonal balance will be affected`

Question 7

What are absorption blockers

Answer 7

Take in fewer calories
Interfere with digestive enzymes (Ingested carbs won’t be digested)
Should be taken before a meal

Question 8

Example of absorption blocker

Answer 8

Chitsin for fat
Stops binding to fat molecules

More fat excretion was found in experimental group as well as weight loss

Causes stress, bloating and nausea

Question 9

What are altering nutrient partitioning

Answer 9

Partitioner affect body composition
Increases lean mass and digests fat maass

Question 10

Example of ANP

Answer 10

Green tea
Increases mitochondria and FA utilisation

Efficacy: increases FA oxidation but weight loss ws not analysed in experiment -> no conclusive result
