About
My name is Chi Phan. Over ten years in product management, twenty in software. I also moderate two French-language keto groups, one of them over 185,000 members.
1. What led me to ketosis
Type 2 diabetes starts with too much insulin. At the late stage, the pancreas's beta cells wear out and die off. That's where my father was: his blood sugar swung wildly, and to bring his lows back up, he ate sugar.
The lung cancer came later, with liver metastases. He died of hypoglycaemia.
I started looking into whether cancer was a genetic disease. That search is how I found Professor Thomas Seyfried, through his interviews, framing cancer as a metabolic disease, and Dr Jason Fung's book The Cancer Code. Ketosis is central to both. My father had never heard of any of it. Neither had I, until then. I don't know whether it would have changed anything for him. But I wanted to understand.
The Cancer Code led me on to the rest of Dr Fung's work, on insulin and on fasting. I started fasting. In 2023, after an extended fast, I was in ketosis for the first time. What stayed with me wasn't the scale — it was the mental clarity. A kind of focus and steadiness I hadn't known before.
I've eaten low carb since 2024, and I've been in continuous nutritional ketosis since July 2025.
2. What I read next
Those two leads took me to everything else. I'm not a doctor or a dietitian: I read for two years before writing the first line of Pallas. PubMed and StatPearls for primary sources, Dr Ben Bikman on insulin resistance, Dr Anthony Chaffee, the Low Carb Down Under lectures, and in French, Drs Dufournet and Sequoia Santé.
3. What I saw in the groups
The same beginner questions come up again and again, starting with macros. The recommendations circulating account for neither age nor activity level. I built a first version of Pallas to calculate them properly, and I ran that calculation for more than 500 members, entering their data myself.
Every time, the same thing followed: the macros were right, and then came the real question — so what do I actually eat?
4. Why Pallas is different
I tried the existing apps. They all ask the same thing: log every ingredient, every day. None are built for ketosis. No ketone tracking. No deduction for the fat that never reaches your plate — what stays in the pan, and what cooking degrades. And macros derived from calories, which makes no physiological sense.
Pallas works the other way round. You enter your profile and your goal, Pallas calculates your macros and plans your meals. You eat, and you measure your ketones.
Pallas is a meal-planning tool, not a treatment. It does not provide medical advice and does not replace medical care. Before changing your diet — especially if you have diabetes, take medication, or are being treated for an illness — speak to your doctor.
