Day 5: The Storage Hormone. Insulin Is Why You Got Fat. Fasting Is the Only Key.

The Hormone That Runs the Show

Day 5. Twelve noon. One hundred and four hours since the last calorie crossed my lips. And we need to talk about the one hormone that decides whether the food you ate last Tuesday is still sitting on your hips today.

Insulin. The storage hormone. The one that nobody explains to you when they hand you the food pyramid in third grade and tell you to eat six servings of grain a day. The one that rides shotgun next to every carbohydrate decision you make and most of the protein ones too. The one that, while elevated in your bloodstream, physically makes it impossible for your body to burn the fat you already have.

You can run ten miles. You can eat clean for a week. You can count macros until the calculator battery dies. If your insulin is elevated, your body is in storage mode, and stored fat stays stored. That is not my opinion. That is basic endocrinology, documented for a hundred years, taught in every medical school, and systematically ignored by the food and diet industry that profits from you not knowing it.

So let us stop ignoring it. Day 5 is the day the paper trail becomes undeniable. The inflammation is gone. The joint pain that used to wake me up has left the building. My 5-mile walk this morning felt like a warmup. My lifts this afternoon will be shorter but not weaker. And the reason is not that I am doing anything brilliant. The reason is that my insulin has been low for four straight days and my body finally has permission to open the storage locker and spend what is inside.

What Insulin Actually Does

Insulin is produced by the pancreas, specifically by the beta cells in the islets of Langerhans. When you eat, insulin rises. When the food leaves your bloodstream, insulin falls. Simple mechanical model. Where it gets interesting is what insulin commands the body to do while it is elevated.

Insulin is anabolic. That means it builds. That means it stores. Every cell in your body has insulin receptors, and when insulin binds to those receptors, the cell is instructed to take in glucose, to take in amino acids, to take in fat, and to stop releasing stored energy. Muscle cells get the signal. Liver cells get the signal. Fat cells especially get the signal.

When insulin is high, fat cells open the door for incoming energy and lock the door against outgoing energy. You can be running a calorie deficit on paper and still gain fat, because the fat you stored yesterday cannot come out while today's bagel is still telling your pancreas to pump insulin. This is the trap that most dieters fall into and never escape. They are eating "less" but they are eating constantly. Breakfast. Mid-morning snack. Lunch. Afternoon coffee with sugar. Dinner. Evening snack. Six insulin hits a day, spread across 16 waking hours, and insulin almost never returns to baseline.

Stored fat, under these conditions, might as well be buried in concrete. You do not have access to it. You cannot use it. You are carrying it around like a backpack you are not allowed to open.

Why Pizza Is the Apex Predator

I love pizza. Loved pizza. Still think about pizza. Pizza is not going to get me, but pizza was the one that got me closest for the longest. And understanding the chemistry of pizza explains why a lot of reasonable, intelligent, disciplined people cannot seem to stop gaining weight on what feels like "normal eating."

White flour is one of the most rapidly absorbed carbohydrates a human can consume. It hits your bloodstream almost as fast as pure glucose. Your pancreas responds by dumping insulin hard and fast. Your blood sugar spikes, insulin floods in to clear it, and your blood sugar crashes below baseline about 90 minutes later. That crash feels like hunger. That crash IS the reason you are still hungry an hour after eating a plate of pasta.

Now add the cheese. The cheese is almost pure fat, and fat by itself barely moves insulin. But when you combine refined carbohydrate with fat, the fat slows gastric emptying just enough to stretch the insulin response out over hours instead of minutes. You are not getting a spike. You are getting a plateau. High insulin. Held high. For hours after the meal is gone.

Then add the sugar in the sauce. Most commercial pizza sauce is loaded with added sugar. Then add the soda you drank with it. Then add the dessert after. You have just spent the next 6 to 8 hours with your pancreas working overtime and your fat cells locked in receive mode.

This is not a moral failure. This is engineered chemistry. The ultra-processed food industry uses the cigarette playbook, and the primary weapon is the carbohydrate-fat combination that hijacks insulin, dopamine, and appetite simultaneously. Pizza is not food. Pizza is a delivery vehicle for a neurochemical event.

"You give me potatoes, you give me lots of fruit, you give me ice cream, you give me cake, you give me pizza, you give me pasta. I can sit down and eat a lot. That is not moderation. That is an addiction."

The Insulin Response, Food by Food

If you only remember one thing from this post, remember the order of that list. Carbs at the top. Fat at the bottom. And stop believing the low-fat lie that drove our country into obesity. Fat is not the problem. Sustained, elevated, relentless insulin is the problem. And the primary driver of sustained, elevated, relentless insulin is refined carbohydrates eaten three to six times a day for forty years.

Why Caloric Restriction Cannot Solve This

This is the part that makes the diet industry furious, but it is true, and the research is overwhelming at this point. Caloric restriction and extended fasting are not two flavors of the same protocol. They are metabolically opposite.

When you cut your calories to 1,000 or 1,200 a day while still eating multiple times a day, your body reads the situation like this: "Food is available, just less of it. This is a famine. Lower the thermostat, slow down everything non-essential, protect the fat stores because we do not know how long this is going to last, and start breaking down muscle for amino acids because muscle is metabolically expensive."

Your basal metabolic rate drops. Your thyroid downregulates. Your energy crashes. Your cravings intensify because insulin is still being triggered constantly by the reduced meals. And when you inevitably eat something celebratory on week three, your body rockets back up past your starting weight and stays there, because now your metabolism is stuck in first gear.

The Biggest Loser contestants proved this at scale. Six years after the show ended, their metabolic rates were, on average, 500 calories per day below where they should have been for their body weight. They were metabolically broken. Most of them regained all the weight and then some, and they regained it on what would be "maintenance calories" for a normal person.

Extended fasting, with zero calories, sends a completely different signal. Your body reads it like this: "Food is not available at all. We need to sharpen up. Raise growth hormone to preserve muscle. Crank up the production of ketones to feed the brain from stored fat. Increase noradrenaline to mobilize energy. We are hunting. This is not a famine. This is pre-meal."

The metabolic rate stays flat or slightly elevated. Muscle is preserved. Fat is mobilized at maximum efficiency. Inflammation drops. Autophagy increases. The body cleans itself out and sharpens its systems. It is the opposite protocol. And it is free.

Ketones: Proof the Metabolism Did Not Slow Down

When you restrict calories but keep eating, your body does not produce ketones in any meaningful quantity. When you fast, your liver starts producing ketones within 12 to 16 hours, and by 48 to 72 hours you are in deep nutritional ketosis. Your urine and breath carry the evidence. Your brain, which normally runs on glucose, shifts to run primarily on ketones, which are a cleaner and more efficient fuel.

This is important because ketones only exist when metabolism is not slowing down. If your body were truly shutting down to conserve fuel, it would not be producing large quantities of an energy substrate and dumping the excess in your breath. The presence of ketones is direct evidence that the body has more fat energy available than it currently needs. The furnace is cranked, and there is spillover.

Connor's ketone math on Day 5: Elevated. Measurable on breath. Confirmed in the way the morning walk felt, in the mental clarity sitting at this laptop, in the fact that the 2-3 PM hunger wave will pass in 20 minutes and I will not think about it again until tomorrow. That is a fueled brain. That is the switch flipped.

The Ones Who Got This Right Before Me

Nothing in this post is original. I am not inventing anything. I am standing on the shoulders of physicians and researchers who have been saying this out loud for decades while the food pyramid and the diet industry drowned them out. If you want to go deeper, these are the people who taught me what I am teaching you.

Dr. Jason Fung, Toronto-based nephrologist, author of The Obesity Code and The Complete Guide to Fasting. The guy who took Type 2 diabetes, which the medical establishment calls a chronic progressive condition, and proved that extended fasting can put it into remission within weeks. His lectures on insulin are free on YouTube. Watch them.

Dr. Pradip Jamnadas, Florida-based cardiologist, one of the clearest communicators on fasting in the English language. His lectures on insulin resistance, fasting and the cardiovascular system, and the metabolic consequences of constant eating are free on YouTube. If you want the cardiology case for why extended fasting is protective, he is your man.

Dr. Benjamin Bikman, PhD in bioenergetics, professor at BYU, author of Why We Get Sick. His work on the cellular mechanics of insulin resistance is foundational. Accessible lectures, deep science.

Her approach is coached, structured, and monitored, which is the right path for most people. If you want a support system, a coach, and a plan with guardrails, her resources are at hittlemanhealth.com. What I am doing is edgy. Her work is sane. If you need sane, go there.

My Electrolyte Protocol on Day 5

Extended fasting depletes sodium, potassium, and magnesium faster than most people realize. As insulin drops, the kidneys release sodium, and water follows. That is the rapid "water weight" that comes off in the first 48 hours of any serious fast. It is also the reason a lot of beginners crash around Day 2 or 3. Low electrolytes feel like the flu. They also feel like hunger. They also produce cramps, headaches, brain fog, and heart palpitations.

I do not use the fancy flavored electrolyte packets. Some of them have artificial sweeteners that may re-activate gut bacteria and trigger insulin responses. Some of them have added sugars. Almost all of them are more expensive than the protocol above, which costs about fifty cents a day in raw materials. More importantly, a fast is supposed to be a break. I am not looking to put an engineered taste experience into my gut during the one stretch of time I am letting it reset. Plain is fine. Plain is the point.

What Hunger Actually Feels Like on Day 5

It is not constant. That is the biggest misconception people have. By Day 5, hunger is not a steady backdrop. It comes in waves, timed to the meals I used to eat. Each wave lasts 20 to 40 minutes, and then it is gone until the next one.

My trouble window is 2 to 5 PM. That is the three-hour block where I historically would have broken for lunch or mid-afternoon food. That is when I have to be careful. Not because the hunger is overwhelming, but because the thought of eating becomes persuasive in that window. For a food addict, the thought is more dangerous than the hunger. The thought is the negotiation. And the negotiation often starts precisely at the moment I feel best.

The evening is easier. I work late. If I am past 8 PM still in front of a keyboard, I am safe. If I am bored, or if I am celebrating something, or if someone texts "grabbing pizza, want to meet up," that is the hour I have to shut the door. Boredom and celebration are the two most dangerous emotional states for a food addict. Nobody talks about this. But if you are one, you know it.

Why I Am Doing This, Again

I have been here before. In 2020 I went from 365 pounds to 230 pounds using exactly the protocol I am running now. I dropped 135 pounds in seven and a half months. I did a single 14-day fast, then strings of 2, 3, and 4-day fasts with careful refeeding on meat, eggs, fish, and vegetables. I rebuilt my body and my metabolism and my relationship with food. For about seven and a half months.

Then I started eating pizza again. Then donuts. Then ice cream. I added testosterone replacement therapy, which my doctor prescribed because my levels were clinically low. TRT gave me energy and muscle-building capacity I had not had in years, and I put on muscle alongside the fat I started re-gaining. I ended up stronger than I had ever been, carrying weight I did not need, sitting at 317.2 pounds the morning of March 16, 2026, staring at a scale and finally admitting the obvious.

The addiction never left. It went quiet for a while. Then it woke back up the moment I gave it the first slice. There is no "moderation" for me. Moderation is not on the menu for a food addict any more than it is on the menu for an alcoholic. One drink, one slice, one cookie, and the door swings back open.

So this time it is different. This time the goal is not weight loss. The goal is permanence. I am walking away from pizza, donuts, ice cream, cake, cookies, pasta, bread, and sugar. The way I walked away from alcohol and cigarettes and chewing tobacco. Forever. Not "mostly." Not "special occasions." Forever.

If I am at a party and everyone is handing out drinks, I do not have "just one." I do not engage. I do not pretend it is a question. Alcohol is not available to me. Cigarettes are not available to me. Pizza is about to join that list. And so are the rest of them.

The Plan for Day 6 and Beyond

No set end date. Someone asked yesterday how long this fast was going to go, and the honest answer is that we are playing with the idea of 40 days. That is the biblical number, it is what long fasters have historically targeted, and it is within range given how the first four days have gone. I am not committing publicly to 40. I am committing publicly to "longer than yesterday." Tomorrow is Day 6. That is the only number I need to know for now.

Breaking the fast, when it comes, will be careful. Bone broth. Small portions. No processed food. No sugar. No bread. Meat, eggs, fish, vegetables, salt, pepper, cayenne, black coffee, water, sparkling water. That is the list. That is the forever list. The stuff that does not come in a wrapper and does not have an ingredient panel longer than two lines.

If This Is You, Too

Maybe you are reading this and some of it sounds familiar. Maybe you have been on the diet merry-go-round for twenty years. Maybe you are the person who can eat "one slice" and walk away, and if that is you, this post is not for you. Go enjoy your pizza. You are not an addict.

But if you are the person who sits down and eats the whole pie. If you are the person who goes through the drive-through on autopilot and powers down food so fast you burn the roof of your mouth. If you are the person who has gotten rid of the evidence so nobody at home would see the wrappers. If you are the person whose weight has been a ten-year argument with yourself that you keep losing. You are not weak. You are not lazy. You are addicted. And addiction has a playbook, and you are running it.

The good news is the playbook is knowable. The chemistry is knowable. The protocol that unwinds it is knowable. And once you understand that insulin is the storage hormone and that caloric restriction cannot get you there, the fog starts to lift. You finally know what you are actually fighting.

The Day 5 Archive Entry

Tomorrow

Day 6. Same rules. Electrolytes, walk, work, lift, document. If something breaks, I will tell you. If something shifts, I will tell you. The whole point of this project is to do it in the open so the next person who is 317 pounds at fifty-six years old has a road map that does not come from a book somebody wrote to sell a meal plan.

The body follows the mind. The mind already moved.

See you tomorrow.
