Outsmart the Menu

What the science says about meals out and long-term health - and what smart eaters do differently

There are times when eating out just feels like the right thing to do. A Friday night after a long week. A midweek breather when your to-do list is breeding like rabbits. A birthday, anniversary - or just a "can't be bothered" Tuesday.

Modern life makes it incredibly easy to skip the stove. Fast food, takeaways, food apps, pub grub, fine dining - whatever you're craving, it's just a few taps (or pyjama-clad steps) away. In fact, restaurant and takeaway meals now account for around one-fifth of US adult calories, with similar trends across most high-income countries.

Now, I'm not here to demonise dinner - but the science has a few sobering things to say about what regular restaurant meals are doing behind the scenes.

Even just a few meals out each week may quietly erode your heart health, metabolic function, and mental wellbeing.

Yes, I know. Buzzkill central. But I’ve been digging into the data, and it’s not a great menu.

In a 2019 survey, 56% of Americans said they eat restaurant or takeout food at least 2–3 times a week. One in ten does so four to six times, and 6% eat out every single day, spending up to 15% of their annual income on not-cooked-at-home meals.

And before you shout, “Surely it’s just fast food that’s the problem?" we’ll get to that. (Spoiler: your fancy bistro isn’t off the hook.)

But first, let’s agree on what counts as a "meal out." I don’t just mean white tablecloths and wine pairings. I’m talking:

• The burger you eat while still in the drive-thru lane

• That pizza box steaming up your car windows

• The Chinese takeout you claim is healthy because it has broccoli

• The fine dining splurge that ends with the bill tucked lovingly into a leather folder, as if that makes it hurt less

If you had to unwrap it, unbox it, or tip for it - it counts.

🍟 What Makes Meals Out a Health Hazard?

So what is it about meals out that makes them so hard on our health?

It's not just the fact you didn't cook it yourself. Meals eaten outside the home, whether from a drive-thru, your favourite Thai place, or that "farm-to-table" gastropub, tend to follow the same pattern: bigger, richer, saltier, sweeter, and less nutritionally balanced than what you’d cook for yourself.

They’re engineered to delight your senses and keep you coming back. And while that’s good for the restaurant’s bottom line, it’s not always great for your blood pressure or your waistline.

Here’s where things go off the rails:

• 👀 Portion Size: Eating out often means supersized portions, especially in the US, where unsuspecting Europeans sometimes assume a single plate was meant for the whole table. Our inner voice whispers, “Don’t waste it,” while our belt buckle pleads for mercy.

• 🔥 Calories: It’s not just more food - it’s more calorific food. A typical sit-down restaurant main can hit 1,200–1,500 kcal. Add a drink, a shared starter and dessert, and you’ve just inhaled a day’s worth of energy, without even noticing.

• 🍷 The Dining Experience: Eating out is a social event. The setting, the menu, the waitstaff’s “Shall we start with some bread?” - they all encourage us to eat more than we normally would at home.

• 🧈 Fats: Fancy food usually means plenty of fat, often butter-based for that silky richness. Chain restaurants and fast food, meanwhile, rely on industrial seed oils that degrade into toxic by-products when overheated. Either way, you’re getting a fat load your arteries didn’t sign up for.

• 🧂 Salt: Salt is a chef’s best friend and your blood pressure’s worst enemy. One study found that the average restaurant meal in the US contains 3,500mg of sodium - 1.5 times the entire recommended daily intake.

• 🍭 Sugar: Fast food places are especially sugar-happy - think fizzy drinks, milkshakes, sweetened sauces. Even savoury items often contain added sugars for extra “craveability.” And let’s not forget the free-refill soda fountains, which quietly turn one drink into three without you noticing. At sit-down restaurants, sugar tends to sneak in more subtly - through rich sauces, glazes, and desserts - but it still adds up fast.

• 🥦 Fibre: In about 80% of meals out, fibre falls below nutritional guidelines. Vegetables are an afterthought. Whole grains? Practically an endangered species.

• 💊 Micronutrients: Sit-down restaurants do slightly better here, especially if you order fish or greens. But overall, people who eat out more often have lower blood levels of essential vitamins, minerals and omega-3s. That adds up over time.

• 🧪 Ultra-Processed Ingredients: Fast food and mid-tier chains rely heavily on ultra-processed foods - burger buns, reformed meats, fried snacks and sugary desserts. These often contain emulsifiers, additives and harmful compounds created during high-temperature cooking. Diets high in ultra-processed foods are linked to cancer, cardiovascular disease, and premature death.

So far, the biggest offenders seem to be the obvious ones: fast food, chain takeaways, ultra-processed “grab-and-go” meals. But what about that elegant little bistro or chef-led tasting menu spot? Surely they’re the exception?

🥩 “It’s Just the Junky Stuff Though, Right?”

Perhaps you're feeling slightly smug, thinking all this bad news relates only to cheaper, fast food joints, not your more sophisticated restaurants. Hate to break it to you... more upmarket restaurants tend to be similar - or worse.

A study comparing fast food and full-service restaurant meals found that both came with extra baggage:

• Calories: Fast food +190 kcal | Full-service restaurant +187 kcal

• Fat: Fast food +11g | Full-service restaurant +10g

• Cholesterol: Fast food +10mg | Full-service restaurant +58mg

• Salt: Fast food +300mg | Full-service restaurant +412mg

From a health perspective, you might as well save your money and go for the burger and fries.

So, if even the fancier restaurants aren’t doing your body many favours… what’s the actual cost of all this eating out?

Turns out, it’s not just about calories or cholesterol. Regular meals out are linked to a laundry list of health issues - and not just the obvious ones.

Let’s break it down.

🧠🍔 How Eating Out Impacts Your Health

⚖️ Weight Gain & Obesity

The more often you eat out, the more likely you are to carry extra weight. Why? Bigger portions, more calories, less fibre - and a tendency to eat mindlessly in social settings.

• In the CARDIA study, people who ate fast food twice a week gained 4.5kg (10 lb) more over 15 years than those who went less than once a week.

• Spanish researchers found that eating out two or more times a week raised the risk of becoming overweight or obese by 33%, and doubled the increase in insulin resistance, which can lead to diabetes.

❤️ Heart Health

Eating out often isn’t great for your arteries.

• In a 16-year study from Singapore, eating Western-style fast food twice a week increased the risk of dying from heart disease by 56%. Four or more times a week? The risk jumped to 80%.

Even if you’re not eating fried chicken daily, regular restaurant meals often mean more saturated fat, salt and refined carbs - none of which your cardiovascular system appreciates.

🩸 Diabetes & Metabolic Health

Meals out = more calories + more sugar + more red meat. That’s the trifecta for increasing type 2 diabetes risk.

• In the same Singaporean study, fast food twice a week was linked to a 27% higher risk of developing type 2 diabetes.

😟 Mental Health

Here’s one that surprises people: frequent consumption of fast food has also been linked to depression and anxiety.

• In a study of nearly 9,000 Spanish graduates, those who ate the most fast food were 42% more likely to be diagnosed with depression over six years.

To be fair, it’s a bit of a chicken-and-egg scenario - people who are already stressed or down may rely more on takeaways. However, the link between poor diet and poor mood is strong and growing.

🪦 All-Cause Mortality

And yes, people who eat out a lot tend to die earlier. Sorry to be grim.

• A study of 35,000 Americans found that eating two or more restaurant or takeaway meals per day was linked to a 49% higher risk of death from any cause, including heart disease and cancer.

📌 Take-Away Message

Let’s be clear: it’s not that one meal out will ruin your health. But when eating out becomes a regular habit, it quietly chips away at nearly every aspect of wellbeing: weight, heart, blood sugar, mood, even lifespan.

If you eat out a few times a week, it's worth asking: Is it pleasure or convenience? And is it worth the slow drip of risk?

🍽️ Does this mean no more meals out?

So, should you cancel your dinner reservations and delete the Deliveroo app?

Heavens no.

A great meal out with family or friends can be a real joy. Shared food, good conversation, the rare luxury of not doing the washing up - there’s real value in that. And sometimes, saying yes to a takeaway is exactly what your mental health needs.

But if you’re eating out two or more times a week, it’s worth pausing to ask:

Is this about pleasure - or just avoiding the faff of cooking?

And:

How often does the short-term win of convenience come at the cost of long-term wellbeing?

Sometimes it’s absolutely worth it. Other times, maybe not. The key is choice, not habit.

If convenience is the main driver, consider ways to bring the effort down at home:

• Could you rotate cooking duties with a partner, housemate, or even older kids?

• Could you batch-cook once or twice a week and live off the leftovers?

• If budget allows, could you try a recipe kit service that removes decision fatigue and shopping?

And when you do decide to eat out, the good news is: it doesn’t have to wreck your health.

Tempting menus and oversized portions may stack the odds against you, but this week’s tweak will help you play the game smarter.

🍽️ HEALTH TWEAK OF THE WEEK

Eating out isn’t the enemy - but doing it too often, or without a strategy, adds up fast.

Meals out more than twice a week are linked to a higher risk of:

• Weight gain and obesity

• Heart disease and high blood pressure

• Type 2 diabetes

• Depression and anxiety

• And yes, a shorter lifespan

But here's the good news: you can still enjoy meals out without playing roulette with your health.

Whether it’s a pub lunch, Friday night curry, or a spontaneous Deliveroo, try these smart tweaks:

• Stick to one course. You're not depriving yourself - you’re dodging the industry’s upsell trap.

• Skip sugary drinks. Go for water, tea, or a glass of wine (if you fancy it).

• Ease off the red meat. Try fish, chicken, or plant-based mains.

• Sauces on the side. Fat and sugar love to hide in dressings and dips.

• Pre-empt the portion problem. Ask for half to be boxed to take home before it's served.

• Ditch the salt shaker. It’s almost certainly salted to the max already.

• Add veg. Actively choose mains with vegetables, and swap fries for a veg side.

• Be salad savvy. A “healthy” salad can rival a cheeseburger in calories once drenched in dressing.

• Scan before you go. Check the menu before you go - your willpower works best when it’s not smelling garlic bread.

Each small shift helps you enjoy the experience without paying for it later.

💡 You’re not just someone trying to eat better - you’re someone who knows how to outsmart the menu.
