Fat Burning Ultimate 5

Question 1

Which blood marker, when chronically elevated, is most associated with impaired fat burning and increased fat storage?

Accepted Answer

Fasting insulin

Answer

Chronically elevated fasting insulin indicates insulin resistance, which suppresses lipolysis and drives energy into fat storage rather than fat oxidation.

Question 2

What is the role of carnitine in fat metabolism?

Accepted Answer

It transports long-chain fatty acids across the inner mitochondrial membrane for beta-oxidation

Answer

L-carnitine acts as a shuttle, carrying long-chain fatty acids across the mitochondrial membrane so they can enter beta-oxidation and be converted to ATP.

Question 3

Which sleep-related behavior most significantly impairs fat loss progress?

Accepted Answer

Getting fewer than 6 hours of sleep per night

Answer

Chronic sleep deprivation raises ghrelin, lowers leptin, increases cortisol, and reduces insulin sensitivity, all of which promote fat storage and impair fat burning.

Question 4

During beta-oxidation of a 16-carbon fatty acid (palmitic acid), how many acetyl-CoA molecules are produced?

Accepted Answer

8

Answer

Each beta-oxidation cycle cleaves a 2-carbon acetyl-CoA from the fatty acid chain; a 16-carbon fatty acid yields 8 acetyl-CoA molecules after 7 cycles.

Question 5

Which of the following best explains why women tend to store more fat in the hips and thighs compared to men?

Accepted Answer

Estrogen increases lipoprotein lipase activity in gluteal-femoral adipose tissue

Answer

Estrogen upregulates lipoprotein lipase in lower-body fat depots, directing dietary fat toward gluteal-femoral storage, which is an evolutionary adaptation for reproductive energy reserves.
