A marathon runner trading carbs for fat at week three. A weight number that stops the scroll. An autoimmune case that moved faster than any doctor predicted. This week delivered on what carnivore does best: real people, real results, shared in public.
1. Thirty Pounds Down in Thirty-Five Days
Carnivore Conviction posted his week-three update and the number stands on its own: 30 pounds since day one, tracked weekly on camera. The comment section is full of people sharing their own first-month results. What stands out is the simplicity of the protocol. No tracking apps, no macros, no supplements. Meat, salt, and water. Watch the update.
2. Allison's Autoimmune Results Came Ahead of Schedule
Allison joined Carnivore RX Lifestyle to talk through her experience with autoimmune disease. She had been given a 90-day window before expecting any improvement. It did not take that long. Her account is specific and measured, not hyperbolic, which makes it worth your time regardless of where you are in the process. Many people in the community report similar early timelines, though individual results vary widely. Watch the interview.
3. A Marathon Runner Goes Carnivore: Week Three
John McDonnell is three weeks into a carnivore experiment ahead of marathon training, and his update is one of the more grounded athlete reports this week. He is deliberately not racing yet, holding off while fat adaptation takes hold. His read on energy and recovery at week three is useful data for anyone thinking about combining carnivore with distance running. Week three update.
4. Bryan Johnson Has an Autoimmune Condition. The Community Has Thoughts.
Bryan Johnson, the tech entrepreneur who has spent millions publicly optimizing his biology on a tightly controlled, plant-heavy protocol, announced this week that he has an autoimmune condition. Shawn Baker weighed in with measured commentary. The carnivore community's reaction has been less measured. Worth watching for the conversation it is opening, not as a verdict on any individual's choices. Baker's take.
5. Ken Berry Takes On the Fiber Maxing Trend
"Fiber maxing" is having a social media moment: the idea that more dietary fiber is always better, and that you should load up on as much of it as possible. Dr. Ken Berry pushes back this week, questioning whether the logic holds. This is the week's one science-adjacent item, kept here as context rather than the main event. Watch the video.
That is the week. See you Monday.
