The stone advice that ran backwards

SELF Newsletter Hi SELF Family, After a kidney stone, somebody probably told you to cut back on calcium. It is the most intuitive instruction in medicine. The stone is made of calcium, so eat less calcium. You cut the dairy. The stone came back anyway. This letter is about what happened when a five-year trial finally tested that instruction head to head. 120 men with recurrent calcium stones were split at random onto two diets and followed for five years. One group got the old advice and cut...

SELF Members Live AMA Thursday, August 27, 6 PM PacificMembers only, about 30 minutes plus live questions Hi SELF Family, Tomorrow evening I go live in the members room. This is the smaller one, where I take fewer questions and go much deeper on each. Every question tomorrow came from you. I pulled 73 questions out of the comments on the last 11 videos, clustered them by how many different people asked the same thing, and then applied one rule: it only makes the list if I can answer it from...

SELF Newsletter Hi SELF Family, You were told to eat more protein. Nobody told you how much, and nobody told you when. So you added a scoop, or a second egg, and the arithmetic at the end of the day looked fine. The strength did not follow. This letter is about why a day can add up correctly and still miss. Start with breakfast, because that is where almost everyone is furthest under. One large egg carries about six grams of protein. Two eggs is twelve. That is a breakfast a lot of people are...

SELF Newsletter Hi SELF Family, If you have kidney disease, someone handed you a list. Cut the potassium. Watch the phosphorus. Put down the banana. You have probably been working from that list for months, and the numbers you were told would improve have mostly stayed where they were. This letter is about what that list is actually worth, measured, and where the evidence puts the real wins instead. Start with the number, because it is smaller than almost anyone expects. Researchers pooled...

SELF Live AMA Thursday, August 13, 6 PM PacificFree, and open to everyone Hi SELF Family, Tomorrow evening I am going live on the channel for an hour. It is free, it is open to everyone, and it stays that way. Once a month I go through what actually published in kidney health and metabolic health, with the journal named and the numbers on screen, so you can judge the evidence instead of taking my word for it. This month I have 6 studies, all from the last 6 weeks, and then I answer your...

SELF Newsletter Hi SELF Family, If your fasting glucose looks fine but your A1c keeps drifting upward, the hours after meals are usually where the drift is coming from. And if you already exercise, you have probably been told the answer is more of it. What the research points to is less about how much you move and more about when. The reason timing matters comes down to how sugar actually gets into a muscle. It does not wander in on its own. It needs a door opened for it, and that door is a...
