Let’s Rethink “Diets”: What a Diet Really Is

Rethinking Diet: A Positive Approach to Food and Well-Being

Be honest—when you hear the word diet, do you immediately think of restriction, rules, and missing out? You’re not alone. But before we throw the whole idea out, it helps to start with what a diet actually is. 

Somewhere along the way, “diet” started meaning a short-term plan we white-knuckle until we hit a number on the scale. It can feel like a rulebook—and the moment life happens and we don’t follow it perfectly, we feel like we “failed.” That’s a tough place to start. 

In reality, your diet is simply what you eat on a regular basis—how you fuel your body day to day. Every living thing has a diet that helps it do well. You wouldn’t feed steaks to a zebra, and you wouldn’t expect a lion to thrive on salad. So the question I like to ask is: what tends to work best for humans? 

Insights from Physical Cues

One place to look is basic human biology (without getting too “science-y”). We have teeth for tearing and teeth for grinding. We can handle a pretty wide range of foods. And our stomach acid is strong—something researchers often bring up when talking about how humans have eaten over time. None of this is a perfect rule, but it’s a helpful clue as we zoom out and look at the bigger picture. 

Another big piece of the puzzle is that “food” today isn’t always the same as “food” a couple of generations ago. All produce has been bred to be sweeter and less bitter. The composition of grains doesn’t match historical grains. Some vegetables we think of as everyday staples were created through cultivation over time. And of course, we’re surrounded by ultra-processed options that are designed to be convenient (and very easy to overeat). 

So, What About the Food Pyramid

If you grew up with the Food Pyramid like I did, you might still have that little picture in your head of what you’re “supposed” to eat. The thing is, those guidelines didn’t come from one clear, settled set of facts—there were theories in play (especially low-fat, higher-carb), plus plenty of industry influence. I’m going to dig into that story—and what it means for you—in a future post. 

Guidelines have changed a lot over the years, and honestly, it can be confusing to know what to trust. Here’s what I keep coming back to: if what you’ve been told to do isn’t working for you, you’re allowed to question it. You’re allowed to look for a better approach—one that supports your health markers, your energy, and your day-to-day life (not just willpower). 

• A “diet” isn’t a punishment—it’s simply what you eat most days. 

• Your body (and your results) can give you clues about what works for you. 

• Modern food is different than it used to be, which changes the game. 

• If the usual advice hasn’t helped, you’re allowed to ask better questions.
