I often see buildup of fatty tissue in stress phases or as inherited stress strategies. Fat means distance, protection, insulation. So this tissue can react in both senses with plus or with minus in stress - certainly also influenced by the kidney tubules and/or glucagon relays..
The typical big belly consists of mainly visceral fat, the big bum of subcutaneous fat.
The original conflict theme would often be protection (CB +/-), but the strategy can lead to self-devaluation (CM -/+).
