Based on a 1995 survey in American Samoa, 93.5% of adults aged 25-64 were either overweight or obese, highlighting the significantly high body mass index (BMI) rates in the Samoan population. This striking statistic underscores a complex health issue driven by a combination of genetic, cultural, and environmental factors.

Research indicates that the heritability of body weight is estimated to be between 40% and 70%. This growing body of evidence suggests that for some individuals, the answer to the question, "Can being skinny be a genetic thing?", is a resounding yes.

Estimates from multiple studies suggest the heritability of obesity ranges from 40% to 70%. This does not mean genetics is the sole determinant, but rather that a significant portion of the population's variation in body mass is attributable to inherited differences. Understanding what is the genetic heritability of obesity requires examining the complex interplay of genetic and environmental factors.

Pacific Islanders, particularly Polynesians, face some of the world's highest rates of obesity and related non-communicable diseases, with prevalence rates significantly exceeding global averages. This health crisis is the result of a complex interplay between genetic heritage, rapid environmental shifts, and cultural factors.
