We know more about nutrition than any generation in human history. We can look up the macros of a sausage roll from the queue in Greggs. And yet we are, officially, the heaviest people who have ever lived. Something doesn’t add up.
It isn’t laziness. Look around.
The lazy explanation — literally — is that everyone eats too much and can’t be bothered to exercise. But that doesn’t survive contact with the evidence. Gym memberships have never been higher. The supermarkets are full of “healthy option” ranges. Half the people you know are on a diet right now. We are not a population that has stopped caring. We’re a population that is trying harder than ever and still losing.
Meanwhile the results keep getting worse: more type 2 diabetes, more heart disease, and for the first time in decades, a generation forecast not to outlive their parents. People this worried, trying this hard, don’t fail this badly because of character. They fail because they’ve been given the wrong instructions.
What actually changed
Go back fifty-odd years and the official advice flipped: fat became the villain, and “low fat” became the health halo on every packet. But take the fat out of food and it tastes like cardboard — so the manufacturers replaced it with the cheapest flavour on earth: sugar.
Look at a modern trolley. Sugar in the bread. Sugar in the pasta sauce. Sugar in the “healthy” yoghurt, the cereal, the low-fat ready meal. We didn’t become greedier — our food became sweeter, everywhere, all at once, while we were being told the real danger was butter.
And here’s the mechanism that matters: a body running on sugar is hungry every couple of hours, because blood sugar spikes and crashes and every crash feels like starvation. So we snack, and the snacks are made of sugar too, and round it goes. That constant background hunger is not a personal failing. It’s chemistry, and it was built into the food.
The uncomfortable part
Why hasn’t the advice been fixed? Partly because institutions hate admitting they were wrong, and partly because an awful lot of money now depends on things staying as they are. The companies selling the sugar also sell the diet ranges. Nobody in that loop profits from you being satisfied after dinner.
You don’t need a conspiracy theory here — just an honest reading of the incentives. The point isn’t to be angry about it. The point is to stop waiting for the official advice to save you, because it isn’t coming.
What actually works
If the problem is sugar and the endless hunger it creates, the fix is almost embarrassingly simple: take the sugar — and the starches that turn straight into sugar — out of your meals, and let fat and protein do what they’ve always done: keep you full.
That’s all keto really is. Drop the carbs low enough and your body switches fuel, from burning sugar to burning fat. The hunger quietens down within days. You eat proper food — eggs, meat, fish, butter, vegetables — until you’re satisfied, and the weight starts coming off anyway, because for the first time in years you’re not fighting your own appetite.
No shakes. No pills. No counting every calorie like a tax return. Just meals your grandparents would recognise, arranged so the chemistry works for you instead of against you.
