About
Who makes this, and why
Sately scores food 0–100 for satiety per calorie — how filling it is for the energy it carries — with a published formula anyone can check. A number that asks for your trust deserves fair questions: who makes this, why, and where the money comes from. This page answers all three.
The story
I'm a Swedish family physician. For twenty years — first in the exam room, then online — I kept meeting the same person: someone doing their honest best, gaining weight anyway, and quietly concluding that they were the failure. I stopped believing that story long ago. Much of the modern food supply is engineered to push you past fullness; when it works as designed, that is not a willpower problem. What decides whether eating less is bearable is satiety — how full food keeps you for the calories it carries. It turns out to be measurable. Almost nobody measures it.
In 2007, between patients, I started a food blog that grew into Diet Doctor — for years the world's largest low-carb site, with half a million readers a day, funded by its members, never by ads or industry money. By 2015 I had left the clinic to run it full time. That work taught me how many people are in this fight. It also taught me, slowly and against my own convictions, that the useful question was never which foods to forbid — it was which foods genuinely fill you up.
My next company bet on exactly that question, as a subscription app. The science held up. The business did not: it cost more to run than it earned, for longer than we could carry, and in 2026 it went bankrupt. I won't dress that up — it failed, and I was in charge. But that failure drew the blueprint for what you're reading now.
Sately is the restart: one person, public science, public data, tiny costs, nothing for sale. In the autumn of 2026 I return to seeing patients as a family doctor — that is my income. Sately doesn't need to earn a dollar to stay alive, and I built it that way on purpose.
Where the money comes from
“Follow the money” is the right instinct in nutrition: ads sell your attention, affiliate links sell products, supplement shops sell hope. So here is mine, plainly:
- Sately is paid for out of my own pocket, from a doctor's salary.
- No investors. No ads. No sponsors. No affiliate links. No supplements or shakes — sold or planned.
- Nothing here is for sale today. If that changes one day, it will be an honestly priced product — most likely the app — never hidden influence. The scores and the method stay free to read.
- If any of this stops being true, this page changes first.
No camp to defend
One more thing to disclose, because anyone who knows my history will ask. I spent fifteen years as one of the world's most visible low-carb advocates. Sately is not a low-carb site — the formula weighs the evidence and nothing else. Watch it show no loyalty:
The potato, which my old world warned you about, lands solidly in the green. Butter, the fat it celebrated, sits at the bottom of the scale. See the full comparison →
If the evidence moves, the scores move — in public.
The rules this site runs on
- Check it, don't believe it. The full formula — weights, limits, change history — is public. When it improves, that's versioned history, not a silent rewrite.
- Uncertainty is stated, not styled away. The method page lists the weakest parts of our own approach before any critic has to find them.
- No food is a sin. Low scores are information, not accusations. There is no red anywhere on this site, because guilt is not a nutrient.
- A day has a zone, not a summit. Foods are facts on a 0–100 scale; living only at 100 is neither possible nor the point. 100 is a fact, not a goal.
Where the project stands
Honestly: early. Today Sately scores 2282 foods and 240 recipes, publishes 6 long-form articles, and explains its method in full. It is a preview build — everything you see is real, and none of it is finished. Next comes an app for tracking whole days. I will use it myself, daily, until it is genuinely good; nobody gets invited before that. No promised dates.
One more honesty: the site says “we.” Today, “we” is one physician and the published science this work stands on. When that changes, you'll read it here.
