I've known this day would come for a while now. My mom has been pestering me about our family tendency toward high cholesterol for years now, but it's never quite made it onto the list of my real concerns. After all, it's not like I was gorging myself on deep-fried or packaged foods, the ones you're always hearing derided on the news. True, I eat fast food a couple of times a month, but it hardly seemed like a regular occurrence, especially compared to the junk-laden diet the "average" American purportedly has. I eat my vegetables, and, heck, I've even been going to the gym semi-regularly.

I probably ought to explain a bit. About six months ago I found out that my primary care doctor was moving to Chicago, which necessitated me finding a new one. I already knew who it would be, since one of the covering doctors I'd seen at the same clinic had struck me as pretty good. I dragged my feet about setting up the new patient appointment, though, which meant I didn't actually get around to meeting the new guy until last week.

We ran through all the normal questions—family medical history (diabetes, cancer, high cholesterol), current problems or medications (none), diet and exercise (OK), weight (could stand to lose some more), and so on. Nothing surprising, and, as always, the vitals and physical were fine. He asked me to stop for a blood draw on the way for metabolic and lipid screening, as well as a vitamin D screening since I mentioned I spend most of my time indoors.

"If anything comes up in your labs I'll call you tomorrow, otherwise you'll get the results in the mail in a week or so," he said.

Tomorrow came and went without a phone call, so I assumed the labs had come back fine, just like always. That turned out to be a little premature, though, as the phone rang on my way out the door Friday morning.

"Turns out you do have a vitamin D deficiency," the doctor said after the initial pleasantries. "I sent a prescription for a loading dose of vitamin D to your pharmacy, so you can start that today or tomorrow." I let my breath out, a little surprised at the tension I'd felt when I heard the doctor's voice greeting me. Vitamin deficiency; I can deal with that.

"Everything else looks fine," he continued. "Liver looks good, HDL cholesterol and lipids are good, LDL is a little borderline but not too high. Sugars are good. Go fill the vitamin D prescription and when the report comes I'll include instructions for the supplements you'll take after you're done with that."

And that was that, I figured. Take a big vitamin dose for a few weeks, some supplements after that, and try to get outside more. Not so bad.

The report showed up in yesterday's mail, and just like the doctor said, there was a vitamin D deficiency and my LDL cholesterol was a little into the "borderline" range. And then there was the recommendation below the table:

"We'd like your LDL to get below 130, preferably below 100. Avoid red meats, eggs, and deep-fried or fast foods. We'd also like to maintain your lipid level in the current range. Avoid desserts and creamy foods."

And just like that, the good times were over.

I told Juliette. "Avoid red meat, desserts, and creamy foods?" she said. "Yikes. Avoid things that taste good, I guess."

I always knew I'd get the "change your diet" note from a doctor eventually, but I figured I had at least until I was 40. Images of thick rib-eye steaks and greasy french fries immediately started dancing in my head, taunting me.

"Well," I said, "I guess this is a good thing, really. Now that it's coming from a doctor, maybe we'll actually have the motivation to stick to a good diet." Juliette agreed. And as we talked about it, the number of changes we'd have to make would be pretty minimal. A little less beef, a little more lean poultry. We already eat a lot of vegetables and don't use a lot of dairy when we cook—in fact, it's pretty common for us to have one or two completely vegetarian meals a week. Nor do any of our normal recipes call for more than a tablespoon of oil. We'll just start skipping desserts again and try to be a little smarter about when and where we eat out. No big deal.

Still, I'd be lying if I said this wasn't weighing on me at all. As much as I love food, it's going to be hard to make even the little changes we talked about. I'll just have to keep reminding myself why I'm doing it.
