Lately I've really been craving beef. Assuming it was because I was low in iron or I wasn't eating the right combination of food, I asked my nutritionist, Katherine Tallmadge, R.D., what she thought. She said desiring a specific dish don't necessarily mean a diet deficiency. And I was surprised that instead of telling me to trick my tastebuds with something healthier than steak, she told me to go ahead and indulge. She said that as long as I take the calories into account, there's no reason why I shouldn't occasionally sink my teeth into a nice juicy filet or sirloin. She also gave me a few tips, like the tenderloin is a lean cut while the rib-eye is pretty fatty, to help me avoid going overboard. Her advice helped me to remember that this isn't a diet that I'm on—it's a way of life. I can have any food I want, as long as it's in moderation.
