(This is the part where I write a clichéd post about realizing that I’m not in my early 20s anymore)

It came to my attention late last week that I am overweight. As in “you better lose some weight, tubby, or that diabetes that’s on both sides of your family will kick in a couple of decades early” overweight.

That realization didn’t set in about three weeks ago during a trip to Old Navy where I bought size 40 waist jeans… where my choices in jeans were sparse because it’s not profitable for a store to stock a trendy clothing line for fatbodies. (If they don’t care enough about their appearance to vomit up their lunch, they’re not as likely to care enough about their appearance to shop at Old Navy, I’d imagine the sales numbers would tell us).

Nor did it set in a couple of months before that when I started to notice semi-permanent red marks in my gut from where my belt buckle presses against it.

Nor even did it set in a couple of months before that when two after-work beers sapped all the energy from me time and again.

It set in when I stepped on my friend’s bathroom scale a few days ago and saw that I am pushing about 250 pounds. Maybe it’s J-School kicking in, but I often need numbers for something to become real to me.

That led me to the realization that I need not just to go on a diet (which I’m going to do starting Nov. 1, by the way), but that I have outgrown the luxury of being able to eat what I want, when I want.

When shouldering adult responsibilities, spontaneity generally leads to a costly indulgence — a self-destructive behavior like an impulse purchase that you’ll be paying for for months, or getting drunk and being hungover at work the next day.

The choice of what to eat was one of the last vestiges of spontaneity remaining in my life. Losing it (along with some of those other behaviors) is bittersweet, because my life overall is much richer now than it was even a year ago, in no small part because of the responsibilities I’ve taken on. I occasionally miss not having to worry about the consequences of what I do, but the trade-off is worth it to me.
