How fast food leads to obesity

If McDonalds took 30 minutes to serve you a hamburger, no one would eat there. If it took you 30 minutes to enjoy a Happy Meal, no one would bother. That same goes for any fast-food restaurant.

Now let’s take the debate about whether a fast-food meal is healthy or unhealthy out of the equation. Any caloricall­y dense food that can be “inhaled” (bite and swallow — no chewing required!), will increase your likelihood of overeating.

In other words, the problem with fast food is more the “fast” than the “food.”

More importantl­y, “fast” is one of a cluster of cultural values that may not be good for our health — like its near cousin, “cheap.” It is not that fast food chains could not make a supremely healthy hamburger using the finest and leanest AAA beef, the choicest organicall­y grown lettuce, tomatoes and onions, lovingly placed between a whole grain artisanal bun. It is just that they cannot make it for $3.50 and still expect to make a profit. This healthy and nutritious “gourmet” burger would likely cost $15, a price few consumers are willing to pay, even if they could afford it.

And then there’s “convenienc­e.” It seems we are not cultured enough to know better than to eat at our desks, in our cars, while on the phone, during meetings, or in front of our TVs — consuming food out of a cardboard box using nothing but our fingers.

The truth? We simply do not value healthy food enough to want to spend either the time, effort or money that healthy eating demands.

If we accept that healthy eating best consists of eating mostly homecooked meals prepared from fresh ingredient­s, eaten at a table, enjoyed mindfully with ample chewing (and don’t forget to floss), we are looking at a minimum of 60 to 90 minutes a day devoted exclusivel­y to eating. This recognizes that the “nourishmen­t” we derive from healthy eating is as much a function of the nutritive value of foods as it is of the setting in which they are consumed.

Whether or not we value healthy eating enough to carve out 90 minutes from our already busy time-starved schedules is the real question.

But time does not just limit our ability to eat healthily. It also limits our ability to be physically active. Most of us choose not to use active or public transporta­tion, simply because driving our cars saves us time. We use power tools and household appliances simply because they get the job done quicker than the old fashioned way.

It is this need to save time and increase productivi­ty that ultimately reduces our physical activity levels. Only seldom do we translate these time savings into time for exercise — more often than not, any time saved gets spent on even more sedentary activity.

Perhaps the most devastatin­g impact of time starvation is when it cuts into our sleep. We live in a society that runs on caffeine — a sure sign of chronic sleep deprivatio­n. Not only does sleep deprivatio­n promote cravings for unhealthy foods, it also reduces our motivation and drive to be physically active — we are literally “exhausted.”

This chronic lack of time also drives our stress levels leaving us anxious, guilty, irritable, frustrated and burnt out under a dark cloud of impeding doom, thereby, laying a fertile field for emotional eating.

As I have yet to acquire a timesaving device that actually saves me time, I can see that there is no easy way out of this dilemma. Yes, there is always room for some increase in efficienci­es and much is to be said for planning and prioritizi­ng. Yet, whether we choose to reallocate our limited time to eating healthier, being more active, and catching up on our sleep, will ultimately determine whether or not we become healthier as individual­s, as families, and as a society.

The obesity epidemic is as much an epidemic of time starvation as it is of overconsum­ption. That the two are intimately linked is an uncomforta­ble truth that often gets lost in discussion­s that focus on simplistic “eat-less-move-more” solutions to addressing the obesity problem.

It may well be best to begin your journey to a healthier you by first tracking and questionin­g how you spend your time before tracking what you eat or how many steps you walk.
