Well done everybody,
and yes the  value conditioning plays a role in this as well!

Here are my explanations accordingly:

4.	Weight gain and obesity without eating more than before
Frame 1: "Before that happened I lost my job and had to stay at home. I was constantly worrying that I can't feed myself and my family!" 
>> starvation conflict (old brain), energy extraction and storage function enhanced + 
(The abandonment conflict >>enhanced water retention in stress phase works in the same sense)

Frame 2: "Before that happened I retired. I was constantly fighting and I had to be the best at my workplace. Now I can enjoy life."
>> resolved social and self-esteem stress (new brain), the body doesn't waste the energy he consumes anymore but builds up tissue +

5.	Underactive thyroid, weight gain and inner coldness, tiredness
Frame 1: "I've been stressed out ever since my partner left me alone with the 2 kids. I can hardly ever manage but I tried. It got worse and worse, and now the energy has all gone"  
>> Long stress phase (old brain), burn-out and depletion of hormones -

Frame 2: "Before that happened I left my old job. I was always on the move, always first, giving 120%, and I didn't take care of myself. Now I can take it much easier and I can work in the home office."
>> resolved stress and physical exertion (old brain), the body reverses the adaptation of hormones in the regeneration phase -

Frame 3: "I feel helpless, stuck and anxious since my partner left me. My life has lost its meaning and I don't leave the house anymore"
>> Dorsal vagal trauma response, reduction of life functions - (This could be perceived either as Old Brain (partner=supply resource) or New Brain conflict (helplessness, loss of love and meaning)
