The case for eating real food

There's a simple question that cuts through most of the noise in the nutrition world: is this food, or is it a product?

A steak is food. A protein bar is a product. An egg is food. A low-fat breakfast cereal fortified with synthetic vitamins is a product. The distinction matters more than most people realise.

The processing problem

When you eat real food — meat, fish, eggs, vegetables, fruit, nuts — your body knows what to do with it. These are the inputs it evolved to process over hundreds of thousands of years. The nutrients are bioavailable. The satiety signals work. Your body regulates energy intake naturally, without you needing to track a single calorie.

Ultra-processed food breaks all of this. The fibre is stripped out. The fats are replaced with industrial seed oils. Sugar and flavour enhancers are added to override your natural satiety mechanisms. The result is food that makes you eat more, not less — and that delivers calories without meaningful nutrition.

What the ancestral lens tells us

Looking at how traditional populations eat — and ate — reveals a striking pattern. The specific foods vary enormously depending on geography and climate. Inuit populations thrived on marine fat and protein. East African pastoralists built their diet around milk, blood, and meat. Pacific Island populations ate root vegetables, coconut, and seafood.

What they had in common was more important than what differed:

• No processed food. Everything was whole, seasonal, and locally sourced by necessity.
• No seed oils. Industrial vegetable oils didn't exist. Fats came from animals, coconut, olive, or palm.
• No refined sugar. Sweetness came from fruit and honey, consumed in small quantities and seasonally.
• Nutrient density. Every calorie carried vitamins, minerals, and other micronutrients. There were no "empty calories."

These populations didn't count macros. They didn't track calories. And they had virtually none of the metabolic diseases that plague modern societies.

What this looks like in practice

I'm not suggesting anyone needs to eat like a hunter-gatherer. But the principles translate directly:

Eat whole food. If it has a long ingredients list, it's a product. If it doesn't need an ingredients list, it's food.

Don't fear fat. Natural fats — from animals, olive oil, butter, avocado — are satiating and nutrient-dense. The low-fat dogma replaced these with sugar and starch, and the results have been catastrophic.

Prioritise protein. Adequate protein supports muscle maintenance, satiety, and metabolic health. Most people, especially over 50, don't eat enough.

Reduce processed carbohydrates. This doesn't mean zero-carb. It means getting your carbohydrates from whole food sources — vegetables, some fruit, perhaps some well-prepared legumes — rather than bread, pasta, cereal, and snack food.

The simplicity is the point

One of the things people find hardest to believe is how straightforward this can be. After years of complicated diet plans, calorie calculators, and conflicting advice, the idea that you can just eat real food and let your body sort itself out feels almost too simple.

But that's exactly what happens. Not overnight, and not without some adjustment. But consistently, and often dramatically.
