I have previously advocated for a moderate lifestyle somewhere between diet freak and total decadence. Many disagree, and the cultural perspectives often do more damage than good, as with many idealized depictions of a false status quo. People seem all too eager to forget that there is a medical distinction between ‘overweight’ and ‘obese.’
Japan has a bipolar view, using Draconian punishment or discrimination against employers and employees for their percentages of body fat, while also glorifying the traditionally obese athleticism of Sumo.
There are undoubtedly many different types of fat, and science is learning and evaluating the risks and benefits of each. In fact, a recent study found that those drastically losing weight increase their risk of damage to the kidneys. In some countries in Europe, where a better grade of cooking oil is used than in the homogenized and processed U.S., no link was found to a diet of fried food and shorter mortality.
And as I (and brilliant minds such as Ron Swanson) have stated before, if you want to ruin your body with grease and calories, how is this any different than the risk taken by somebody who smokes, or drinks, or skydives, or joins the military, or works in law enforcement or fire emergency services?
(Ron Swanson is a fantastic icon in that, as an ardent outdoorsman and craftsman, he also endorses physical activity, sports and exercise.)
And ultimately, like polio or the black plague before us, we will gradually learn to overcome the perfectly contemporary threats of cancer, diabetes, and the (as-yet unproven) risks of GMOs, as mere artifacts of our time.
