In June 2026, Sri Lanka’s Ministry of Health did something quietly radical. It banned a long list of foods from every school canteen in the country — sausages, burgers, pizza, doughnuts, ice cream, biscuits, cakes, pastries, instant noodles, flavoured milk, energy drinks, deep-fried snacks, even bottled sauces — for roughly four million children. In their place: rice, fruit, vegetables, fish, eggs, unsweetened drinks.
If parts of that banned list surprised you — if some of it just sounds like normal food, the stuff kids eat — then you’ve already found the problem. The things we’ve quietly accepted as everyday food are, in many cases, the very things slowly making us unwell. And the science explaining why has moved fast in the last two years. Most people simply haven’t heard it yet.
This article is that update. No fads, no guilt, no complicated rules. Just what the evidence now says, and what you can actually do about it.
The real villain isn’t sugar. It’s “ultra-processed” food.
We’ve all been told sugar is bad. True — but it’s only part of the story. The bigger culprit is an entire category of food that scientists call ultra-processed: products built in factories from refined ingredients, additives and preservatives, engineered to taste irresistible and last forever. Think packaged biscuits and snacks, soft drinks, instant noodles, sweetened cereals, sausages, most things in a shiny wrapper.
For years the concern was just weight and diabetes. The newer findings are about something we never connected to food at all: the brain.
-
A major 2024 study in the journal Neurology found that the more ultra-processed food people ate, the higher their risk of memory and thinking problems — and of stroke.
-
A 2025 analysis from the long-running Framingham Heart Study found that each daily serving of ultra-processed food raised Alzheimer’s risk in middle-aged adults by about 13%. People eating ten or more servings a day had nearly triple the risk.
-
Further 2025 research linked heavy intake to early signs of Parkinson’s disease.
In other words, the packaged snack isn’t just expanding waistlines. It appears to be dulling minds — including, most worryingly, young, developing ones. Across Sri Lanka, parents and grandparents lovingly hand children sweets, chocolates and crisps as treats, as comfort, as convenience. The love is real. The harm is invisible — until years later, when it isn’t. Think of the potential we may be quietly stifling: children who could be sharper, calmer and stronger, fed convenience instead.
Why “eat less, move more” keeps failing you
Here’s something the fitness industry won’t tell you: you cannot out-exercise a bad diet. You can train hard for years and barely move the needle, because food — not exercise — does roughly 80% of the work in body composition and health. Exercise is wonderful, and you shouldn’t drop it — keeping muscle through strength training is one of the best predictors of a strong, independent old age. But as a weight-loss tool on its own, it’s weak. Don’t expect the gym alone to make you lean.
And the popular explanation for diet failure — “you just need more willpower” — is mostly wrong. Willpower is the wrong tool, because the problem is biological, not moral.
Part of the reason is that ultra-processed food is designed to defeat you. Companies engineer products to hit a precise “bliss point” of sugar, fat and salt that overrides your body’s natural “I’m full” signal — so you keep eating long after you should have stopped. That second packet disappearing without you noticing isn’t weakness. It’s the product working exactly as intended. (This is the core idea behind the bestselling book Ultra-Processed People.)
Take sleep, which almost nobody connects to eating. After a single bad night, your body becomes worse at handling sugar (insulin sensitivity can drop by around 25%), your brain craves sweet, calorie-dense food more strongly, and you eat more the next day — even after a full meal. Chronic stress does something similar, pushing you specifically toward sugar. So when you’re tired and stressed and surrounded by processed food, your own biology is actively recruiting you to eat the wrong things. Fighting that with sheer discipline is exhausting, and it’s why diets collapse by February.
The way out isn’t more willpower. It’s changing what’s on the plate and around you, so the easy choice becomes the healthy one.
What actually works (and it’s simpler than you think)
People want to know which diet “wins.” The reassuring answer: nearly all the good ones agree on the basics, and the basics are simple.
For living longer and healthier, the evidence isn’t close — the Mediterranean way of eating wins again and again: vegetables, beans and lentils, nuts, whole grains, olive oil, fish, with very little red or processed meat. It was ranked the world’s #1 diet in 2025, and it’s tied to lower rates of heart disease, diabetes, several cancers and dementia, plus slower ageing at the cellular level. It tops the list partly because it’s enjoyable and sustainable — real food people can eat for life.
For repairing damage that’s already done — losing fat, killing cravings, fixing blood sugar — cutting carbohydrates (lower-carb and ketogenic eating) is a powerful tool. And this leads to a fact most people find genuinely shocking:
Type 2 diabetes can often be reversed with food. Not just managed — reversed, with blood sugar returning to normal and medication reduced or stopped, under a doctor’s care. Landmark trials have shown it. For a disease that exploded from 200 million cases worldwide in 1990 to 830 million by 2022, that’s not a minor detail. It’s one of the most underused pieces of good news in medicine.
Notice what the winning approaches share, because this is the whole secret: whole foods, almost no ultra-processed junk, little sugar, plenty of fibre, protein and good fats. The argument over Mediterranean-versus-keto is a rounding error next to the gap between either of them and how most of us actually eat.
Two quick myths worth retiring:
-
You don’t need three meals a day. There’s nothing biological about it — it’s a modern habit. For thousands of years humans went long stretches without food. Eating within a shorter daily window (say, finishing dinner early and delaying breakfast) helps many people effortlessly, because hunger turns out to be more schedule than need.
-
Juice is not a health food. Juicing a fruit throws away its fibre and leaves you a glass of fast sugar. Eat the fruit. Don’t drink it.
The shortcut everyone’s asking about
You can’t talk about weight in 2026 without the injections — Ozempic, Wegovy, Mounjaro. They work, and dramatically: the strongest can take off around a fifth of a person’s body weight. For people with serious obesity or diabetes, they’re a real medical advance, not a cheat, and nobody should feel ashamed of using them.
But look closely at the catch, because it quietly proves the whole point of this article. Stop the drug and the weight usually piles back on; most people who quit end up restarting. The injections also tend to strip away muscle along with fat, and — strangely — people on them often move less. In other words, the medication quiets your appetite, but it doesn’t teach your body anything or change what’s in your kitchen. The day it stops, you drift back, unless the food underneath has changed. A drug can buy you a head start. It can’t do the one thing that lasts: fix what’s on the plate.
Feed your gut, not just yourself
One of the biggest shifts in modern nutrition is the realisation that you aren’t really feeding yourself — you’re feeding the trillions of bacteria living in your gut, and they, in turn, influence your weight, your immune system, your mood and even your brain. A rich, varied gut community protects you. A depleted one is linked to obesity, diabetes and Alzheimer’s.
So what builds a healthy gut? Fibre helps — but the surprise winner is fermented food. In a Stanford trial, people who ate more fermented food saw their gut diversity rise and their inflammation fall, more reliably than those who simply ate more fibre. The good news for Sri Lankans is that this is already in our heritage: curd and buffalo curd, fermented rice and string-hopper batters, our pickles and achcharu. We’ve been quietly trading them for packaged snacks. Trade back.
The things almost nobody told you
A few quiet truths that surprise most people:
Milk may not be your friend. Most South Asian adults are lactose intolerant — that’s the genetic norm here, not the exception. And for the many people with an underactive thyroid (very common, often undiagnosed), dairy can make things worse: in one study, restricting it actually improved thyroid function and how well thyroid medication worked. Milk doesn’t suit everyone the way we were taught it does.
“Healthy” labels lie. Fruit juice, “low-fat” flavoured yoghurt (sugar added to replace the fat), most granola and breakfast cereals, “multigrain” breads that are still refined flour, sports and energy drinks, sweetened plant milks. The front of the pack is marketing; the truth is in the ingredients list. And switching to “diet” or “zero-sugar” versions isn’t the escape hatch it seems — the World Health Organization now advises against artificial sweeteners for weight control, and they may interfere with your gut and blood-sugar control too.
Sugar can quietly scar your liver. You don’t need a drop of alcohol to get liver disease. Fatty liver — now the most common liver disease in the world — is driven heavily by sugar, especially the fructose in sweet drinks. It usually causes no symptoms for years, then becomes serious. The good news: caught early, it’s largely reversible just by cutting the sugar.
Seed oils aren’t the poison the internet says. You’ve probably heard that cooking oils like sunflower and canola are silently “inflaming” us. The actual scientific consensus is that they’re fine in normal amounts — and better for your heart than butter, lard or coconut oil. Their bad reputation comes mostly from the fried and packaged junk they happen to be used in. Blame the chips, not the oil.
Alcohol gives no free pass. Your body treats it as a toxin to clear first, switching off fat-burning while it does — empty calories headed straight for the liver and the waist.
There’s plastic in us now. This one is new and unsettling. In 2025, scientists found tiny plastic particles building up in human brains — far more than in 2016, and more still in people who’d had dementia. Another study found them in the arteries of most patients examined, who then had about 4.5 times the risk of heart attack or stroke. We don’t yet know the full meaning, but it’s a good reason to drink from glass or steel rather than that scratched, discoloured plastic bottle that should’ve been thrown out a year ago.
Living longer and living well
There’s a difference worth burning into memory. Lifespan is how long you live. Healthspan is how long you live well — mobile, sharp, independent, free of disease. We’ve come to accept a long, sick old age as just “what ageing is.” Much of it isn’t ageing at all. It’s accumulated damage, most of it from food, most of it avoidable.
The same way of eating that helps you live longer also helps you live better right up to the end — stronger, clearer-headed, steadier on your feet into old age. There’s no good reason most people should fade as fast as they do. Eat well, and you can plausibly have both.
The encouraging part
None of this is hopeless — quite the opposite. The younger generation is waking up fast; with good information a search away, more people understand real nutrition than ever before. And governments are starting to act. Sri Lanka’s school-canteen ban is a genuinely serious step, and the current administration has shown more willingness to tackle food and nutrition than any before it.
There’s more to do, and it’s worth saying out loud: the food pyramid taught in schools is outdated, built on a carbohydrate-heavy base when the science now favours more protein and good fats — we’re handing children the wrong map at the most important age. And food labels need real policing; companies should not be free to dress up unhealthy products in healthy-sounding words. A country’s strength rests on its people: you cannot build a great nation on a sick population.
This is also a quiet plea to anyone thinking of starting a business — Sri Lanka does not need another dessert shop. It needs people making the healthy option the convenient, affordable, desirable one. That space is wide open.
It’s exactly that gap that led to Keto Queen. It began as a home business selling waffles — and was getting popular — until a simple realisation stopped it: would we feed this, with all its sugar, to our own children? The answer was no. So it was rebuilt around a single mission: developing genuinely nutritious, low-sugar alternatives to the processed foods Sri Lankans eat every day. The first is a nut mix — walnuts, almonds, pecans, pistachios and cranberries — balanced for protein and healthy fats to actually fill you up instead of spiking and crashing you, with almond-milk drinks and more to follow. One small business can’t fix a country’s food culture. But enough of them, pointed the right way, can shift it.
Where to start — without overhauling your life
No crash plan. Pick a few and keep them:
-
Cut packaged, ultra-processed food first. Not just sugar — the whole wrapper-and-barcode category. This is the single biggest win, for body and brain.
-
Eat real food. The fewer steps between a plant or animal and your mouth, the better. If your grandmother wouldn’t recognise it as food, be suspicious.
-
Put protein and good fats in every meal. They keep you full and break the craving cycle.
-
Eat fruit; don’t drink it. Keep the fibre.
-
Treat sleep and stress as part of your diet — because they quietly control your cravings.
-
Drink from glass or steel, not plastic.
-
Aim for permanent, not perfect. A 90% version you keep for life beats a flawless one you quit in a month.
One honest caveat: nutrition isn’t perfectly one-size-fits-all. Genes and individual metabolism mean people respond a little differently, and anyone with a medical condition should change their diet with a doctor’s guidance. But the direction of the evidence is about as settled as this science gets — away from ultra-processed food, toward whole foods, fibre, protein and good fats.
We spent a long time blaming willpower and worshipping the gym. The real leverage was never there. It was always on the plate.
