Know What You're Really Eating.

Take a picture of any food — restaurant meals, packaged foods, drinks, raw ingredients, you name it. Get an instant rating of how good it is.

Two important scores.

FoodKnower rates your food on the two things that matter for healthy eating.

Food Integrity

Is your food industrially processed?

  • 75+: Minimally processed
  • 50–74: Lightly processed
  • 25–49: Heavily processed
  • < 25: Ultra-processed
How is this calculated?

Based on the NOVA food classification system (Monteiro et al.), extended with:

  • Additive burden ? counts and classifies emulsifiers, sweeteners, flavour enhancers, colours, and preservatives
  • Industrial markers ? detects maltodextrin, modified starch, syrups, hydrogenated fats, protein isolates
  • Functional stacking + category priors ? how many engineered roles are present, adjusted by product type
  • Guardrails ? traditional and single-ingredient foods are protected from over-scoring

Overeating Risk

Is your food engineered to override your feelings of fullness?

  • 65+: High risk
  • 35–64: Moderate risk
  • < 35: Low risk
How is this calculated?

A weighted combination of two sub-scores:

Nutrient analysis (40%) ? checks Fazzino et al. (2019) hyperpalatable clusters: Fat + Sodium, Fat + Sugar, Carbs + Sodium.

Ingredient formulation (60%) ? scans the ingredient list for palatability signals:

  • Position of sugar, oil, salt in ingredient list
  • Synergistic reward combos (sugar x fat, fat x salt, sweet x salty)
  • Snack-architecture patterns (chips/crackers, chocolate, flavoured-salty)
  • Beverage penalty and simplicity bonus for short, clean lists

Privacy

We value your privacy and don't store any of your photos on our servers.

It's simple.

Three steps to knowing exactly what you're eating.

1

Take a photo

Point your phone at any food — a restaurant meal, a packaged product, a home-cooked dish — and snap a picture.

2

Get your scores

In seconds, see how processed your food really is and how likely it is to make you overeat.

3

Eat smarter

Use your scores to make better choices. Over time, build habits that stick — no calorie counting required.

Why both scores matter.

"It has additives and chemicals, it's junk food."

That's right. Junk food is easy to overeat, because it bombards you with artificial flavors, and that makes you eat more and more.

But is all natural food good? No. A freshly home baked cookie, thick and chewy, melting in your mouth, is all natural, but you'll still eat hundreds of calories and want more.

Up to now, most diet approaches only look at one side. You can't eat carbs, or fat, or anything with additives. Or you look at the Glycemic Index or 'satiety score'.

That's a blind spot. You need to know what's been done to your food. And you need to know what your food will do to you. You need the whole truth.

My Story

Like many people, I've always wanted to keep my weight under control. I've tried all kinds of diets, like low fat, low carb, no sugar and starch, intermittent fasting... they would all work for the first few months, but then stop having any effect. How could this be? Is it a lost cause, and weight loss drugs like Ozempic the only way forward?

Something kept nagging at me. What if there was something common to all these diet plans? Then it hit me like a lightning bolt one afternoon, when I was surfing the internet:

Plain white rice. People in Asia eat rice every day without getting fat. There was an argument on the low carb forums — how can they eat so much rice without becoming overweight? There was no good answer.

So I consulted the latest nutrition science. It turns out that white rice is fine! Potatoes are okay. Some kinds of bread are good. Plain pasta, too. What Fazzino's hyperpalatability research shows is that we overeat because our food has been engineered to make us overeat. Manufacturers put in additives to make it taste good. They create combinations of flavors and textures that make you reach for the next potato chip. They bypass the signals of fullness that stop us from overeating.

And yet, we can't just rely on the presence of additives and chemicals. Consider a home baked cookie, or a simple potato chip with just potatoes, oil, and salt. These all have natural ingredients, yet the research shows they cause just as much weight gain. Health? Weight control? They're related, but different. We need two scores: one for how easy it is to overeat, and one for how artificial the food is.

Many healthy foods still cause overeating. And it's not always intuitive which ones.

Browsing through many food and nutrition apps, I found there were none that focused on these two things. So that's why I created FoodKnower: to share the research with everyone, in a way that's simple and convenient to use.

A way to eat healthy without giving up tasty foods.

A way to lose weight without fighting your body and starving yourself.

I reached my target weight in nine months, without once feeling hungry. I wish I found this out many years ago.
