How to Eat
Navigating a food industry that was not designed for your health
I don’t have time to make lunch today.
That’s not an excuse. That’s a Tuesday.
Between work, calls, errands, appointments, and everything the day asks of you, the drive-through is not laziness. It is math. It takes four minutes and it is done. It is a sandwich. Maybe a side salad off the value menu. You could do worse.
So you do it. And then you do it again the next day because yesterday worked out fine. And somewhere in that loop, convenience stopped being a workaround and became the plan.
That is not a personal failing.
That is the food industry doing exactly what it was designed to do.
Few countries have built a food environment as convenient, processed, and relentlessly marketed as ours.
Drive-throughs on every corner. Eating in the car between appointments. Dinner in front of the television. Lunch while scrolling. We have normalized eating as a background activity, something that happens while we do something else, and in doing so we stopped paying attention to what we were actually eating.
And the food industry noticed.
Ultra-processed food is built for exactly this moment. It is designed to be eaten quickly, taste good immediately, last on the shelf, and make you want it again tomorrow. The ingredients list is long because it has to be: shelf stability, flavor enhancement, texture, color, and the specific combination of salt, fat, and sugar that keeps the product easy to overeat.
There is a reason a fast food hamburger can sit on your counter for weeks and not decompose. Real food rots. Food engineered for shelf stability and repeat purchase has been processed so far from its original form that even bacteria do not quite know what to do with it.
That is what you are eating in the drive-through.
You did not fail your diet.
You were up against a system with a much bigger budget than your willpower.
Maybe you decide to take back some control. You start cooking at home, making your own meals, and head to the grocery store with good intentions.
And then you stand in the cereal aisle for ten minutes.
Forty-seven options. Heart healthy. High protein. Low sugar. Made with whole grains. Natural flavors. No artificial colors. The box is bright, the font is friendly, and somewhere on the front it says something about fiber. You pick the one on sale. The marketing worked. It was designed to.
Here is what most people do not realize: the grocery store is not a neutral space. Shelf placement is purchased. Eye level is premium real estate. The end caps are not there because those products are the best options. They are there because someone paid for that placement. Words like “natural,” “wholesome,” and “artisan” sound reassuring, but they do not protect you from a bad ingredient list.
You are making decisions inside a system designed by people whose job is to get you to buy a specific thing.
That is not a fair fight without a framework.
So here is the framework.
Start with what to avoid.
If you see fructose on the ingredients list, put it back. There are enough other options. You do not need to negotiate with a product that was designed to keep you wanting more.
Then read the rest of the list. If it reads like a chemistry set, put it back. The longer the list and the less it looks like food, the further that product has moved from anything your body actually needed.
And dyes. Red 40. Yellow 5. Blue 1. If your food needs artificial coloring to look appealing, that is information. Real food has color because of what it is. Processed food often has color because of what was added to sell it.
Now the green flags.
The ingredients list is written in descending order by weight. That means the first ingredient tells you what the product mostly is. If the first ingredient is oats, tomatoes, chicken, beans, olive oil, or brown rice, you are starting from a better place. If the first ingredient is sugar, enriched flour, or corn syrup, you are not.
Look for foods with shorter ingredient lists and words that belong in a kitchen. Tomatoes. Rolled oats. Olive oil. Almonds. Lentils. Chicken. Rice. Yogurt. Eggs. If the first few ingredients sound like food, that matters more than whatever promise is printed on the front of the package.
You do not need to be perfect. You need a better filter.
Now the practical part.
Not everyone has a Whole Foods nearby. Sierra Vista, Arizona does not. Most of America does not. Telling people to shop the perimeter of a specialty grocery store is advice for a specific zip code. The rest of us are navigating a regular grocery store, a budget, and whatever is actually available.
So go in with a list. Better yet, go in with a meal plan. Not elaborate. Simple.
Pasta and jarred sauce is a perfectly reasonable weeknight meal. Add fresh bell peppers, onions, and garlic to that sauce and you have improved it significantly without adding much time or cost. That is not compromise. That is smart navigation.
Bread can be part of a healthy diet. When you can, choose bread with simpler ingredients and less processing. Sourdough is usually my first choice. Whole grain breads are generally a better starting point than standard white bread. But the bigger point is not moralizing bread. It is understanding what you are eating, how much of it you are eating, and what role it is playing in your day.
Oils matter more than people think. Extra virgin olive oil is my everyday default. Avocado oil is a reasonable option for higher heat. And butter versus margarine? Butter wins. Real butter is food. Margarine is an industrial imitation of it. That does not mean you need to fear every spread on earth. It means when you have the choice, choose the thing your body actually recognizes.
Real food. Shorter list. Closer to the source.
Now let’s talk about your goals, your age, and the conversation nobody wants to have but everyone needs.
Start with your goal. Not the internet’s goal for you. Not what the person next to you at the gym is doing. Your goal.
Are you trying to maintain your weight, lose it, or build muscle?
The answer changes everything.
Then be honest about your day. A sedentary job is a major variable that most people underestimate. Two or three days in the gym does not cancel out eight hours of sitting. It helps. It matters. But it does not erase the rest of the day.
The body keeps a running tab.
And then there is age.
A 28-year-old male lifting five days a week with testosterone running at full capacity does not have your metabolism, your hormones, or your recovery window at 40 or 50. His body is doing work yours is not. He recovers faster. He builds muscle faster. That is not superior discipline. That is biology.
I wrote a case study on this exact pattern, published in Medicine & Science in Sports & Exercise in 2011: a simultaneous rupture of the pectoralis major and triceps tendons in a 50-year-old man who owned a gym. He had a history of heavy lifting but had taken a year off while dealing with golfer’s elbow. He underwent steroid injections, physical therapy, and was eventually cleared to return to lifting. There was a younger man in the gym, lifting heavy, loud, full of that young male energy that can pull older men into proving something they do not need to prove. The 50-year-old knew better. He knew he was not where he used to be. But maleness comes out in strange ways. On his third bench press attempt, he was already starting to feel tired. He felt a throb in the right shoulder and knew he should stop, but he also knew he was going to finish the lift. Then came a sudden, sharp, searing tear through his upper arm and chest. The bar dropped. This was not muscle fatigue. It was a traumatic rupture. He ultimately had to go through surgery, and I followed him through that experience.
He admitted later that he knew better.
But that is the point.
The weights do not know how old you are.
You have to.
And I do not think this usually plays out the same way with women. Women can absolutely overdo it. But this particular collision of youth, ego, testosterone, and refusal feels distinctly male.
Metabolism changes with age. Hormones change. Recovery changes. Perimenopause, menopause, declining testosterone, loss of muscle, changes in body composition — these are not excuses. They are physiological realities. They require a different strategy, not more self-blame.
Working out more does not automatically mean you can eat more.
It means you need to eat smarter.
And yes, I believe in a cheat day.
I do not think people do well trying to be perfect seven days a week. Most of the week, stay mindful. Stick to the plan. Eat in a way that matches your goals. But then give yourself one day when you stop counting, stop negotiating, and just eat what you want without guilt. Late-night Taco Bell? Fine. Dessert? Fine. A bigger dinner than usual? Fine. Enjoy it.
Then the next day, get back on track.
Mine is Friday.
I look forward to Fridays. In fact, I love Fridays.
Build a way of eating you can actually live with, and the cheat day stops feeling like rescue.
The food industry was not designed for your health.
But you do not have to navigate it blind.
Read the first ingredient. Notice the length of the list. If you see fructose, put it back. If it reads like a chemistry set, put it back. If the product is built more around marketing than food, put it back.
Go in with a plan. Know your goal. Eat for the life you actually live, not the one you keep promising yourself starts Monday.
Eat with more awareness. Eat with more context. Eat for the life you actually live.
For paid subscribers, the companion piece to this essay is Real Food, Real Life — how I actually eat, how I prep for the week, and what this looks like in an ordinary life.
And yes, enjoy your Fridays.
Next week we leave the grocery store and head somewhere else entirely.
