有個理論 ,set point 既 upper limit 係 base on 有冇被獵食既危險
Itis suggested thatthis
release from predation might have created the conditions for allele frequencies ofthe genes coding forthe
upperintervention pointto drift overtime, and what we now experience is the consequence ofthat drift.
Some individuals have been lucky in the ‘mutation lottery’ and can stillregulate their weight and adiposity
because their upperintervention point has not moved, but, for others,the intervention point has drifted
upwards and the strong control preventing weightincreases is no longer present. This suggested individual
variability in the distance between the upper and lowerintervention boundaries is a key aspect ofthe model.
