4 important questions on Physiological needs - Hunger

Short term appetite direct us towards the glucostatic hypothesis. This hypothesis suggests?

Blood- glucose (plasma glucose) levels are critical to hunger. When low the lateral hypothalamus will send the signal HUNGER. When high the ventromedial hypothalamus will signal ENOUGH

Long term energy direct us to the lipostatic hypothesis, which says?

Fatt mass drops -> Ghremlin promotes hunger
Fatt mass Increase -> Leptin promotes enough

The lipostatic hypothesis suggest the set point theory, what does this theory say?

Every individual had a biologically genetical determined body weight.

Lacking a negative feedback system, dieters are highly vulnerable to binging.
Give two reasons why?

  1. We like to think that we have cognitive control and willpower, and that  it is way stronger than the physiological control and hunger urges (underestimate)
  2. restrait - release (environment and feelings can distract us from our cognitive control)

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
