Hormonal

Fetal growth restriction (thrifty phenotype) combined with a transition to an energy-rich urban lifestyle causes insulin resistance and metabolic syndrome in adulthood, whereas maintaining a traditional frugal lifestyle prevents these outcomes despite early malnutrition.

If you were small for your gestational age, your body is biologically programmed to store energy efficiently. Moving to a modern, high-calorie environment triggers this programming into metabolic disease. To mitigate this, you must prioritize a lifestyle that mimics your early-life constraints: high physical activity and controlled energy intake, rather than assuming standard dietary advice applies equally to everyone.

GoodConditionalHIGH confidence
It is this rapid transition within a single lifespan that is implicated by many researchers as a crucial causative agent in the explosion of non-communicable diseases in many such urban areas.

Based on observational cohort studies in The Gambia and India showing strong correlations between birth size, lifestyle, and metabolic markers.
