A life-history theory perspective on obesity

We extend Nettle et al.’s insurance hypothesis (IH) argument, drawing upon life-history theory (LHT), a developmental evolutionary perspective that documents downstream consequences of early-life exposure to unpredictable environments. We discuss novel evidence consistent with both IH and LHT, suggesting that early-life exposure to unpredictable environments is associated with reduced engagement in weight management behaviors and a greater probability of adulthood obesity.
