High obesity rates among Pacific Islanders stem from a combination of lifestyle shifts (less physical work, more sedentary habits), a drastic move from traditional diets to cheap, processed, energy-dense imported foods (like mutton flaps, sugary drinks, refined flour), and potential genetic predispositions to store fat, all exacerbated by colonial history that disrupted food systems and promoted population growth, leading to reliance on imported goods.
Nutrient transmission (change in diet) is the primary cause of the obesity epidemic in the Pacific Islands, with a high amount of imported foods high in salt and fat content.
Results: Obesity prevalence was the highest in non-Hispanic AIAN (44.0%; 95% CI, 38.2%–50.1%), followed by 42.7% (95% CI, 40.5%-44.9%) in non-Hispanic Black adults. Compared to other groups, non-Hispanic Asian adults reported the highest fruit and vegetable intake.
It was reported that the frequency of obesity in Polynesians is higher than the others. This result was due to the high expression of PPARGC1A gene with frequency of 0.7 in Polynesian. Therefore, the same study concluded that PPARGC1A gene could be a candidate gene for obesity and T2D in Polynesian (Myles 2007).
Becker, et al, reported that, traditionally, some Pacific Islanders associate power and status with large body sizes. In New Zealand, Metcalf, et al, found that Pacific Islanders with higher BMIs, compared to Whites with higher BMIs, were more likely to see themselves as either under or normal weight.
The bigger body frame of the Pacific Islanders was once attributed to the history of traveling by canoe, working on the farms, and doing manual labor; however, modern technology has changed these physical activities to more sedentary lifestyles (Ulijaszek, 2003).
The findings help provide additional evidence supporting the long-standing theory of why Polynesians of today have a distinctive body type – relatively larger, heavier, bulkier – that is more often found in populations that live in higher latitudes with colder climates.
with an obesity rate of 71.7%. Nauru is known to have the highest rates of obese inhabitants worldwide. The average body weight among Nauruans is approximately 100 kilograms (220 lb). Nauru has an average BMI between 34 and 35.
Obesity is more prevalent among American Indian and/or Native Alaskan (31.2%), non-Hispanic black (20.8%), and Hispanic (22.0%) children compared with their white (15.9%) and Asian (12.8%) peers.
Asian women had the lowest prevalence of obesity, whereas AA women had the highest. Gender disparity in obesity prevalence appeared to be largest in AAs. Among men, ethnic disparities in obesity prevalence were largest between Latino and Asians.
The traditional diet in Japan is built around a base of rice and other grains, with plentiful consumption of vegetables and fruits, and also fish, but relatively little animal fat, meat and sweets. In Japan, the presentation of the food is very important, and particular attention is given to the colors and textures.
West Virginia topped WalletHub's 2025 ranking of the most overweight and obese states in the U.S., published Nov. 4, while Colorado is the healthiest-weight state.
Abstract. The human settlement of the Pacific Islands represents one of the most recent major migration events of mankind. Polynesians originated in Asia according to linguistic evidence or in Melanesia according to archaeological evidence.
Life expectancy, in years
The latest value from 2023 is 71.7 years, an increase from 71.55 years in 2022. In comparison, the world average is 73.65 years, based on data from 196 countries. Historically, the average for Samoa from 1960 to 2023 is 66.58 years.
Globally, Australia ranks 10th among OECD countries for overweight and obesity, with a prevalence rate of 64%, exceeding the OECD average of 59%.
Least Obese Countries by Population:
I Went to The Most Crowded Island on Earth (without Police) - Santa Cruz del Islote in northern Colombia is the most crowded island on Earth, with density of population a staggering 68,000 people per square kilometer. I went there and tried everything that the most densely populated island in the world offers.
Some would also say it was because of the unhealthy diet that lead the populations to be severely obese. A very interesting answer was that the Polynesians had practiced an old form of eugenics, mostly selecting larger and stronger partners for the sake of war and combat.
Genetic studies
(2008) also confirmed that Polynesians are genetically closer to Micronesians, Taiwanese Aborigines, and Islander Southeast Asians.
Both Gagana Sāmoa and ʻŌlelo Hawaiʻi belong to the same Polynesian family, yet Hawaiian is considered an Eastern Polynesian language while Samoan is a Samoic-Outlier language.
Seventy percent of Americans may now be classified as obese, according to a new study authored by Harvard Medical School researchers investigating an updated definition for obesity. This figure is up from 40 percent of the population who meet the old threshold for obesity, defined as a Body Mass Index higher than 30.
The right variety and amount of exercise can both reduce body weight and prevent weight regain. In addition, it may improve: Endocrine and immune body responses related to adipose tissue dysfunction, including insulin sensitivity.
More than 60% of adults in Polynesia and Micronesia were living with obesity in 2022—the highest rate in the world. This is likely to be a result of changing diets and a culture that puts a value on size. Tonga had the highest rate for women (81% were considered obese); American Samoa had the highest for men (70%).
