Questions and Answers

What is the result of intense hunger triggered by the process described?

  • Loss of fats stored in the body (correct)
  • Increased energy levels
  • Weight gain
  • Reduced appetite

    • What is the effect of the process on the body's fat?

  • Increase in fat storage
  • Conversion of fat into energy (correct)
  • Maintenance of current fat levels
  • Fat becomes a secondary energy source

    • Despite eating more, why does weight loss occur?

  • Because the body is more efficient at digesting food
  • Because the body stores more fat in muscles
  • Because the body burns more calories
  • Because the body uses alternative fuels stored in fat (correct)

    Study Notes

    Adrenal Glands

    • The adrenal glands have two main sections: the adrenal medulla and the adrenal cortex
    • The adrenal medulla secretes catecholamines
    • The adrenal cortex secretes adrenocortical hormones, which include:
      • Cortisol
      • Physiologic functions:
        • Plays no important role in maintaining energy balance under resting conditions
        • Important during periods of food deprivation (fasting, stress, and starvation)
      • Effects on protein metabolism:
        • Inhibits lipolysis
        • Insulin promotes protein storage

    Cortisol

    • Physiologic actions:
      • Important during periods of food deprivation (fasting, stress, and starvation)
      • Plays no important role in maintaining energy balance under resting conditions
    • Effects on protein metabolism:
      • Inhibits lipolysis

    Insulin and Protein Metabolism

    • Insulin promotes protein storage
    • Effects on protein metabolism:
      • Stimulates amino acid uptake into all cells and stores in muscles
      • Decreases blood amino acid level
      • Inhibits lipolysis

    Diabetes

    • Both Type I and Type II diabetes share many of the same signs and symptoms
    • Physiologic actions:
      • Triggers intense hunger
      • Leads to weight loss despite eating more than usual due to the body using alternative fuels stored in fat
