One hundred years ago, there was precious little obesity. We have not changed physiologically since then. Two things have changed:
- How much fuel (food) we're putting in our tanks (bellies) (and it's "octane level" - how many calories it has per unit volume); and
- How hard/far/long we're running the engine (i.e., the manual work our bodies perform daily)
Instead, they would like to express their "free will" in more bizarre ways. Such as the free will to take a pill, promulgated by an opportunistic and profiteering Big Pharma that will castrate the ability of the supposed free will to take in excessive calories laden with the key ingredients of fat, salt, and sugar. The free will is perhaps not so free after all. Or, they would like the free will sign up to undergo a grotesque and profitable surgery (for the surgeon and the hospital) that makes it physically impossible to take in excessive calories and digest and absorb them - a form of controlled mutilation and usurpation of the normal anatomy of the body, initiated by the free will in order to account for its own inadequacies when tasty food is within reach .
So, we are back to Ulysses, tying himself to the mast to prevent himself from responding to the sirens' call; and Thomas Schelling's game theory strategies in Choice and Consequence. Wire your mouth shut, don't buy crappy food and make it available in your home, forsake fast food, relinquish electric appliances when manual ones will do, ride your bike, walk, choose city living over suburbia, take the stairs, walk your dog, take your family for a stroll around the park, prepare your meals painstakingly from basic ingredients, grow a garden, raise your own animals, grind your own coffee, use a broom rather than a blower, push a reel mower......or sign up for controlled mutilation ("gastric bypass"), toxic quasi-efficacious diet pills, fad diets (Adkins), and every other manner of convenient obfuscation of the underlying problem: exposure and acquiescence to an environment which is rife with excessive and easy-won calories coupled with escape from the basic work of daily living via modern carbon-producing conveniences.
But you can't have it both ways - you either want to restrict your options, or you want someone else to restrict them for you. Think carefully about which path shows true respect for your free will and the sanctity of your body, which the mystics claim is your temple.
