See the Opportunity in the Obstacle
#132
Last Friday at 4:00 PM

Wouldn't it be nice if every day was sunny and the breeze was at our back? For better or worse our health path is often filled with "rainy days" just when we think the sun should be shining.

It's fall in Wisconsin and it's raining today. I got the camera out to the lake and stood in the rain. Bringing us some footage of the rainy lake and some wet leaves. The reality of what some may call a "dreary" space can still have it's own beauty if we look for it.

Doc Says "Stop 16:8 Now" (Thomas DeLauer Show)
#131
Last Thursday at 4:00 PM

Today I'm going to share some thoughts about a video with a doctor who says "Stop doing 16:8" and address some of the confusion it causes.

Link to that is here: https://youtu.be/qQbrb9LGJOU

Honestly, I really like the video and encourage people to watch it. Would love to have a conversation with Thomas DeLauer and/or Dr. Schoeff about it, in the event some internet magic brings it to them.

I am going to suggest this framing is missing some nuance, but I love the broader point of the video that i...

Overthinking Happiness | Think Smaller
#129
10/12/2026

Most things we do, one way or another, are ultimately efforts to find happiness. Sometimes we make the objective so big that it seems we may never accomplish it and happiness will remain elusive. In short, we can really overthink it.

Think smaller. Happiness is often not some grand accomplishment. It can be as small as a simple cup of coffee in the morning. Let's share one and have a chat!

Fasting-Induced Overeating
#121
08/31/2026

Fasting is a powerful weight loss strategy. But some people can have an experience that pushes them out of a centered and emotionally grounded place and into a zone of overeating. This is something I want people to be very mindful of and avoid.

In this session I am going to dive into some fasting philosophy and a number of scientific studies that will help us understand the physiology of fasting in the bigger context of the emotions of eating.

We will discuss who is most at risk for overeating and practical strategies to move...

The Global Shift to Eliminate Insulin Resistance
#110
07/23/2026

Modern medicine has long claimed that severe insulin resistance is a progressive, permanent process. But new international data is proving otherwise.

In this livestream, Dr. Philip Zimmermann breaks down the landmark INTERFAST-2 study published in Diabetes Care and reveals how a global shift in clinical science is changing how we approach weight loss, insulin dependence, and metabolic health. The data has already influenced major standards of care including those from The American Diabetes Association.

Whether you are struggling with a weight-loss plateau or looking to safely eliminate your dependency on diabetic medications, this presentation dives...

Believing you can lose weight is step one...
#105
07/15/2026

Believing you can hit your goal weight is essential. But optimism without appropriate action is just a wish. In this live stream, we are breaking down how to bridge the gap between a positive mindset and actual, real-world fasting weight loss results.

We’re diving into a powerful philosophy: "Assume that everything will work out, and then do the work to make it true." If you are tired of starting over every Monday, it’s time to move past wishing and step into active execution. Always with a mindset of grace mixed with determination.

Escape to Fasting Island
#103
07/14/2026

Escape the constant noise of the snacking mainland and step onto "Fasting Island."

An island has its own rhythm—a protected, peaceful space where you are officially on "island time." In this live session, we are shifting our mindset and treating fasting exactly like that. It’s a way of protecting and valuing the space inside the body, completely separate from the consumption of modern culture.

When you create that quiet space, your metabolism shifts. The body stops taking things in, starts releasing stored fat as fuel, and you naturally drift into weight loss.

Yesterday, a YouTube viewer left a comment about the suggestion that we can take a break from eating: "Are you a doctor? You shouldn't be giving advice like this." Their username? Runaway Train.

Well, yes, I am a doctor and no I am not giving medical advice. But more importantly, that username is such a wonderful description of modern food culture that we have to lean into it.

We’ve been conditioned to think that "frequent eating" is normal, but this constant consumption is a runaway train driving our collective metabolic health off a cliff. In...

Science of GERD: How Weight Loss and Fasting Stop Acid Reflux
#97

Is acid reflux ruining your sleep, or are you looking for a solution to chronic heartburn? In this deep-dive scientific review, we move past the generic advice and look at what peer-reviewed clinical data actually says about GERD, weight loss, and fasting.

Instead of quick fixes, we are breaking down the physiology of the lower esophageal sphincter (LES), how intra-abdominal pressure from visceral fat triggers reflux, and how strategic fasting windows can give your digestive tract the rest it needs to heal.
