They are fat because they eat more. Especially lots of fat. They have the highest fat% diet in the world and the highest obesity. They may be genetically predisposed to eat more, but there's no magic genetic trait that makes some people defy thermodynamics and other not.
There have been some studies where they took fat south pacific islanders and put them on their ancestral diet of lots of starches (tubers mostly) and they lost weight. If you stay either low fat or low carb, it tends to limit calories and it's hard to get fat. The most tasty food - donuts, cookies, pizza, mac and cheeze, ice cream, ... are both high fat and high carb. Any limit you put on yourself that gets you to think before you eat and avoid junk food will help you limit calories.
Pacific Islanders are also more muscular than the rest of the world. They are heavier and more robust.
People don't understand that obesity amongst sedentary is measured through BMI, and that different populations carry different levels of body fat at equal BMI. A PI with a BMI of 30 will be leaner than an non PI at this BMI., and they are not likely to be considered overweight at a BMI of 25.
There are quite a few study comparing them against different populations and they have a tendancy to carry more lean mass.
