I mean, it's kind of trivially preventable on the personal level: * Eat mostly non-processed meats/proteins, low-starch vegetables, low-sugar fruits, and non-polyunsaturated cis fats * Eat high-starch vegetables and high-sugar fruits sparingly * Generally avoid most other foods * Generally avoid harmful drugs such as nicotine and alcohol * Incorporate some light physical activity into your daily routine (walking is an easy one) * Ideally, lift every now and then All of this should be within reach of most Americans. If someone accepts it as a viable strategy and commits to it, they can maintain or trend toward a healthy body composition. Applying this on a societal level seems like a much bigger challenge to me. So much terrible nutritional advice is ingrained in the minds of the public (e.g. the food pyramid), so many terrible dietary choices are normalized and made convenient, and the whole "standard American diet" has so much economic momentum that convincing the public to change their lifestyles all at once might be a disaster in and of itself. Imagine an alternate reality where the only soft drinks were La Croix and Zevia, McDonald's only served stir-fried meats and veggies with sides of berries, Dunkin' Donuts only served watermelon slices and coconuts, cereals and oatmeals were replaced with low-sugar trail mixes, etc. The obesity epidemic wouldn't exist.
