waps with a newspaper No. Fat in either extremes of deficiency or excess is not harmless. The biggest harm that comes from supreme leanest is a reduction in reproductive potential because of the role of fat in signalling energy availability via leptin secretion...low energy availability means banging or being banged is low on priorities.  Increased mass through fat increases mechanical wear. It breaks the leptin/hunger feeback loop in the brain. It gives rise to endocrine disruption through secondary aromatisation of testosterone in males. It aggravates PCOS in females. It promotes an inflammatory state within the body (which is pro cancer, pro nuerological/cognitive disorders, which is why fats are often depressed and stupid). Yes, diet is the causative factor of why they have excess adipose tissue but diet doesn't cause respiratory disorders, nor does it directly cause high blood pressure (this is a result of compression or constriction of the circulation system, mass and aerterial calcification/plaque both contribute)....however obesity is the comorbidity when looking at Covid19 prognosis.
