Thomas DeLauer Recap: Dr. Jon Schoeff on Visceral Fat, Insulin and a Doctor-Led Fasting "Reboot"

The latest full video on Thomas DeLauer's official YouTube channel, "Visceral Fat Doctor: The Fasting Reboot Protocol for Belly Fat and Insulin Resistance", was posted on October 25, 2026 and runs about 56 minutes. DeLauer, a fitness and nutrition content creator, talks with Dr. Jon Schoeff, a physician who describes himself in the video as "a simple country surgeon from Ohio" and who uses fasting with patients in his practice. They discuss why he thinks people with significant insulin resistance and a lot of visceral (deep belly) fat need a different approach than healthy people, what happens in the body during a longer fast, why he is skeptical of simply eating less, and where he sees new weight-loss medicines fitting in. These are the speakers' own views, often stated strongly, and the approach Dr. Schoeff describes is one he runs with patients under his own supervision, so treat this as a conversation to bring to your doctor, not a plan to follow.

The views and claims described below belong to the speakers, not to GNOUP. This is general information only and is not medical advice. Extended fasting and prescription weight-loss or diabetes medicines carry real risks and should only be considered with a doctor's guidance. Please talk with a doctor or other qualified healthcare professional before changing your diet, starting or stopping any fasting routine, or taking any supplement or medication. This matters especially if you have a medical condition (including diabetes, heart, liver or kidney disease), take any medication (especially for blood sugar or blood pressure), are pregnant or breastfeeding, are under 18, or have a history of an eating disorder. GNOUP has no connection to any product, supplement, medicine, sponsor or paid offer mentioned in or around the video and does not promote any of them.

Key health tips and takeaways

These are ideas from the interview, not instructions. GNOUP has not checked the studies, numbers or claims, and the video does not name specific studies for most of them.

• Start with real measurements. Dr. Schoeff says his approach is "all data driven." He looks at blood markers such as fasting insulin and HOMA-IR (a common estimate of insulin resistance), visceral fat from a body-composition scan, signs of fatty liver and muscle mass before deciding what a patient should do. The practical takeaway: ask your doctor which of these markers make sense for you.
• Fasting is a tool, not an identity. He stresses that fasting is "just a tool" and a "means to an end," and says his goal is better health markers, not being "the fasting guy." He says an approach meant to fine-tune a healthy person can be "a complete debacle" for someone who is very metabolically unhealthy, which is why he individualizes it.
• Medical help is not cheating. He says he respects people with the willpower to do things alone, but that if a person's mental toughness is what stands between them and better health, he would rather use medical support to close that gap.
• Expect discomfort, and know why. He says people who are new to longer fasts can feel shaky, weak, headachy and preoccupied with food ("food noise") while the body shifts from burning carbohydrate to burning fat. In his view much of that is craving rather than a real lack of fuel. Anyone who feels unwell while fasting should stop and contact a doctor.
• Put your energy into "calories out." Rather than focusing only on eating less, he says every fasting plan in his practice is built around a regular gym schedule, because muscle needs exercise signals to be maintained or built. DeLauer adds that people should move "as much as you possibly can within reason."
• Treat visceral fat as a priority. Both speakers argue that deep belly fat is not just stored energy but tissue that sends out inflammatory signals, and that reducing it should be taken seriously. Dr. Schoeff sums up his priorities as reducing visceral fat and bringing insulin down.
• Look beyond the scale. He says the conversation should be about body recomposition (more muscle, less fat) rather than weight loss alone.

Newsworthy insights

These are claims and opinions from the video. GNOUP has not verified them, and other experts may disagree.

• A "metabolic reboot" for the sickest patients. Dr. Schoeff describes a more intense, multi-day fasting approach that he uses in clinical practice for patients with severe insulin resistance, tailored to each person's numbers and monitored with glucose and ketone tracking. We are not repeating its schedule here because it is a medically supervised protocol, not a do-it-yourself plan.
• High blood sugar during a fast. He says he has seen very insulin-resistant patients whose blood sugar stays above normal even after several days without food, which he takes as a sign of how much stored fuel they carry. DeLauer and Dr. Schoeff explain this partly through gluconeogenesis, the body making new glucose, and argue that much of it comes from the glycerol part of broken-down fat rather than mainly from muscle. DeLauer says he can't recall the exact share.
• The liver as the "mainframe." Dr. Schoeff calls the liver the body's "metabolic supercomputer" and says metabolic disease starts there and then shows up in muscle, so lowering liver fat is central to his approach.
• "Fasting is not a time experience." He argues that fasting is a biological state, not a number of hours, and that someone whose insulin stays high may never truly be in a fasted state. He calls intermittent fasting "time-restricted eating" and says it can be a fine tool for maintenance but, in his view, is too gentle for serious metabolic disease.
• Ketones as the scoreboard. He says rising ketones are his favorite marker during a fast because, as he puts it, several other conditions, including insulin coming down, have to be met first.
• Skepticism about "calories in, calories out." He agrees that eating less can improve insulin resistance for people who stick with it, but calls it slow, hard to sustain and prone to plateaus as the body adapts. DeLauer adds that the equation is hard to apply when mitochondria (the cell's energy factories) don't use fuel well.
• Starvation versus fasting. Dr. Schoeff draws a line between what he calls stress-driven "starvation physiology" and "fasting physiology," which he links to the energy-sensing pathway AMPK and the hormone glucagon.
• Views on retatrutide. Dr. Schoeff says he is eager for retatrutide, an experimental weight-loss drug that he says is not yet on the market, and explains it as a "triple agonist" acting on GLP-1, GIP and glucagon receptors. He cites phase 3 results of about 28% body-weight loss and says the glucagon effect seems to appear only at higher doses in the studies he has seen. GNOUP has not checked these figures, and anything involving prescription medicines is a conversation for a doctor.
• The insulin and glucagon "dance." Borrowing from Dancing with the Stars, he describes insulin and glucagon as partners that should be in balance, and says that in many people insulin dominates.
• AMPK and mTOR as dials, not switches. Both speakers say the body's growth (mTOR) and repair (AMPK) pathways work like dials that are constantly adjusted, and Dr. Schoeff criticizes efforts to simply switch mTOR "off." He mentions several compounds and medicines he sees as smaller "dials," which we are not listing here as recommendations.
• Mitochondria and aging muscle. DeLauer says he recently visited a lab in Switzerland that studies a compound related to mitochondrial health, and describes how researchers there compare it with exercise and fasting. He says he is not telling everyone to take it.
• Strong statements on diabetes risk. Near the end, Dr. Schoeff says people with diabetes face several times higher rates of death, heart disease, stroke and other illnesses than the general population. These are figures he gives from memory without naming a source.

About this summary

This recap was prepared from the video's title, its description and chapter list, and an automatically generated transcript of the interview. The transcript has no timings or speaker labels, so we attributed points to the guest or the host where the content made it clear. The transcript misspells the guest's name; we used "Dr. Schoeff" and "Jon" from the video description and his linked Instagram handle. We left out the sponsor segment, the specific fasting schedule, drug doses, supplement and medication mentions offered as "dials," some blunt remarks and some unverified statistics. Automatic transcripts can contain errors, so names and numbers may differ from the audio. For the exact words and context, watch the video.
