Atul Butte died yesterday. The world lost a giant. A big bear of a man. With a huge smile. With love for everyone. With energy that could power a room. I loved everything about Atul. I loved how he was always happy. I loved how excited he was about science and helping people.

Many moons ago, @KevinH_PhD and I talked about a book we both wished existed. No fads, no weight loss hacks—just the nutrition and metabolism science. I’m thrilled to announce that we wrote it! Out September 23 @Avery_Books & available now for pre-order. penguinrandomhouse.com/books/671334/f…
I’m excited to announce my new book FOOD INTELLIGENCE coauthored with brilliant journalist @juliaoftoronto! Cutting through the confusion about diet & health, #FoodIntelligence describes the fascinating science of how food both nourishes and harms us. penguinrandomhouse.com/books/671334/f……
We have a second drug… as I tell people, they are both my babies, but this one is especially near and dear…
This weekend, we presented preclinical data on MAR002 for the treatment of #acromegaly at #ENDO2025. The data strongly support advancing MAR002 into clinical development for acromegaly treatment, and we look forward to staying on track to initiate a Phase 1 First-in-Human study…

As a CEO, the day to day work and mission (patients, team) is really rewarding and what drives so many of us. With that said, I sometimes see colleagues lose sight of the fact that we need to deliver what we promised to shareholders. What you told them you would do as close as…
This is long and complicated but so important. Being persuasive does not = being honest
This is completely false. Here's why: The "study" being referred to was a preliminary analysis by CDC scientists of health records for ~124,000 children conducted in 1999, called the Vaccine Safety Datalink study. But this 1135% increase in the rate of autism figure did NOT…

Nice to see this being shared broadly
Genetic variants that reduce ApoB concentrations reduce the risk of coronary heart disease. The more they lower ApoB concentrations, the more they reduce the risk of heart disease. This is amazingly clear causal evidence.
I’ve been on this site for almost 16 years and for many, if not most of them, I’ve posted quite a bit about Ruthie and what it’s been like to raise a kid with a disability. I’ve been pretty quiet lately, but yesterday, she graduated from high school and was selected to give one…
Holy shit I had no idea. RIP @atulbutte
Between alarms and sheltering, I learned last night that my postdoc mentor, Professor Atul Butte @atulbutte, has passed away, and he is only 55 years old. This is devastating news 💔. Atul was a giant in so many ways. He was a visionary leader in translational bioinformatics…
For almost exactly 20 years, one of our kids has gone off to spend the day at a school here in SF. Today is the last day

People still talking generally about seed oils as though they're all one thing - they commonly vary in their omega 6, omega 3 and omega 9 content. Even oils with the same name (eg safflower) have high n6 and high no (high-oleic) varieties. Some seed oils (eg palm kernel) are…
