I stopped dieting somewhere around sixty, and it's the best thing I've done for my body since I started lifting again.
That sounds backwards, so let me explain. For most of my working life, eating was something that happened to me. Airport lounges, client dinners, whatever was in the hotel minibar at 11 p.m. after a delayed flight. When I'd try to get it under control, I'd reach for a diet — some named plan with a rulebook and a countdown timer running in my head all day. It worked for about three weeks every time. Then a trip, a birthday, a long week would knock it over, and I'd be back where I started, a little more discouraged.
What finally stuck wasn't a diet. It was a system — a small set of rules simple enough to survive travel, restaurants, and a normal social life, because a plan you can't keep on the road isn't a plan, it's a punishment you've scheduled for yourself.
Here's the whole thing.

Rule one: a window, not a menu
The single change that did the most for me was deciding when I eat instead of obsessing over every bite of what I eat.
I keep an eating window of about eight hours and let my body fast the rest. In practice that means I don't eat first thing in the morning. Coffee, water, and I get on with the day. The first real food shows up early afternoon, and the kitchen closes a few hours before bed.
I want to be honest about what this is and isn't, because there's a lot of noise around fasting. It is not magic. It didn't melt anything off me on its own. What it did was quieter and, for me, more durable: it took the constant low-grade decision-making out of the morning. No breakfast to plan, no mid-morning snack to feel guilty about. Fewer eating decisions in a day means fewer chances to make a bad one. That's the real mechanism, at least for me — less willpower spent, not some metabolic sorcery.
It also is not for everyone, and I'd be doing you a disservice to pretend otherwise. If you're on medication that needs food, if you've ever had a difficult relationship with eating, or if the idea of skipping breakfast makes you feel unwell rather than clear-headed, this rule is the first one to throw out. The system still works without it. Which brings me to the part I'd never skip.
Rule two: protein is the anchor
If I could only keep one rule, it would be this one.
After fifty, the body stops volunteering to hold onto muscle. You have to ask for it — with resistance training, and with enough protein to actually rebuild what the training breaks down. I train a push/pull/legs split with free weights and cables, and none of that work matters if I don't feed it. Skip the protein and you're doing the hard part of getting stronger with the brakes on.
So protein is the anchor of every meal. I build the plate around it first and let everything else fill in around the edges. A rough target I aim for is somewhere near my body weight in grams of protein across the day. I don't weigh it on a scale or log it in an app anymore. I've eaten this way long enough that I can eyeball it: a real portion of eggs, fish, chicken, Greek yogurt, or a good steak at most meals, and I know I'm in range.
If you use a protein powder to close the gap on a busy day, the tub I keep in the cupboard is Levels grass-fed whey — but there's nothing magic about the brand. Any clean whey, or a plant isolate you actually like, does the identical job. The food comes first; the powder just fills a corner.
The reason I'm strict here and loose almost everywhere else is that muscle is the one thing the second half quietly takes from you if you let it. It's not about looking good in a photo. It's balance, it's carrying your own bags through an airport in your seventies, it's getting off the floor without thinking about it. Protein and lifting are how you keep that. Everything else on this list is optimization. This one is the foundation.
Rule three: eat food that looks like food
I don't count carbs and I don't fear fat. What I do instead is a lot simpler to remember: I try to eat things that would have been recognizable as food a hundred years ago.
Vegetables, fruit, fish, meat, eggs, olive oil, nuts, good bread when I want it. If it comes in a box with a long ingredient list and a cartoon on the front, I'm not militant about it, but it's not what I build meals from. This isn't a moral position — it's a practical one. Whole foods are harder to overeat, they keep me full through a long fasting window, and they don't leave me hunting for a snack an hour later.
Notice there's no forbidden list here. Nothing is banned. That's deliberate. The second you ban a food, you've made it the only thing you can think about — I learned that the expensive way, over years of failed diets. Instead of "never," the rule is "mostly." Mostly real food, most of the time, is a bar I can actually clear for the rest of my life.
Rule four: the table travels
Here's where most eating plans fall apart, and where this one has to earn its keep, because my partner and I travel — a lot.
The system flexes on the road, and I've made peace with that being a feature, not a failure. When we're somewhere worth eating, I eat. I've had broth in a market in Southeast Asia and a long lunch in the south of France and I regret none of it. What I don't do is let a good trip quietly become a bad month. The window and the protein anchor come with me. If I've had a spectacular dinner, I'll simply push the next day's window later and lean hard on protein and vegetables until things settle. No guilt, no penance, no "starting over Monday." I just steer back to center.
That's the whole philosophy in one line: the system holds the line; it doesn't hold you hostage. A rule you break on every vacation isn't a rule you actually have. A rule that bends and comes back is one you'll keep for twenty years.
What a normal day looks like
People always want the specifics, so here's an unglamorous real one:
Morning is black coffee and water while I get moving. I train, or I walk. Early afternoon I break the fast with something protein-forward — eggs and vegetables, or fish and a salad, nothing complicated. Late afternoon or evening is the bigger meal, usually a real portion of meat or fish, a pile of vegetables, and whatever else the table's offering. If there's a glass of wine or a proper dessert at a dinner with friends, it's in the window and it's part of the meal, not a crime scene. Then the kitchen closes, and I let the overnight fast do its quiet work.
That's it. No powders, no thirty-day challenge, no app buzzing at me. Two meals most days, built on protein, eaten inside a window, mostly from real food, flexible when life is worth being flexible for.
If your day doesn't look like mine
I need to be honest about one thing: the schedule I just walked you through — coffee through the morning, the first meal in the early afternoon, a workout whenever I feel like it — is a retired man's day. That timing is a luxury of the second half, not a requirement of the system. If you're still working, still commuting, still building the career that pays for all of this, don't for a second think this isn't for you. It just wears a different watch.
Strip it down and the system is only two things: the window and the protein anchor. Where you put the window is entirely yours. Start at six and need breakfast to survive a nine o'clock meeting? Eat it — then close the kitchen earlier in the evening and let the fast happen overnight while you sleep. If the only slot you have to train is six p.m. after work, that's when you train, and you make sure protein lands around it. Lift fasted before dawn if that's your thing; eat first if you can't function without it. The clock is a tool, not a commandment.
What never moves is the anchor. Whenever you eat, build the plate on protein. Whenever you train, feed it. Mostly real food, most of the time, inside whatever window your actual life allows. A retiree and a person with a packed calendar can run the identical system — I just have more room to fuss over the timing, and truthfully that freedom matters less than you'd think.
If you want the fuller version — how to bend this around shift work, travel weeks, and a real nine-to-five — that's one of the things I go deep on in the Second Half Playbook.
The honest trade-offs
I promised myself I'd never sell you the upside without the downside, so here they are.
You will feel a little hungry in the mornings for the first couple of weeks. That passes, but it's real, and if it doesn't pass for you, that's information — listen to it. Skipping breakfast is genuinely antisocial some mornings; when the grandkids want pancakes, you make an exception, and the exception is the point of having a flexible system in the first place. And two meals a day means each one has to actually deliver your protein, which takes a little intention at first. This is a system that rewards paying attention, not one that runs on autopilot from day one.
There's also a limit to what any of this can do, and I want to be square with you about it. I'm a retired technology executive who reads a lot and pays attention to his own body. I am not a doctor, a dietitian, or your doctor. What's written here is what has worked for me, at my age, with my training and my health. Before you change how or when you eat — especially if you take medication, manage a condition like diabetes, or have any history of disordered eating — talk to a professional who knows your actual numbers. The best version of this system is the one your doctor has seen and signed off on.
Why it works when diets didn't
The diets failed me because they were built to end. There was always a finish line — thirty days, ten pounds, the wedding — and a finish line means there's an "after," and the "after" is where it all comes back.
A system doesn't have an after. It's just how I eat now, the way brushing my teeth is just what I do. It asks for less willpower, not more, because I've removed the daily negotiations instead of trying to win them. And it's built to survive the exact things that used to wreck me — the travel, the celebrations, the ordinary chaos of a full life.
That, more than any single meal, is the whole idea of the second half. You're not chasing a before-and-after photo anymore. You're building something you can keep. Eating included.
