Your blood sugar is high right now, right? Maybe it is 180, maybe it is 280, or maybe it goes up and
comes back down. Maybe your doctor just called and you want it down. You want it down fast. And here's
the truth though. You can move the needle significantly in 24 hours. Not with a medication,
not with some detox tea, but with biology. Because your body has mechanisms built specifically to
drop the blood sugar rapidly. Most people never activate them. Now because nobody explained how
they work to you, right? And I'm going to walk you through today exactly what to do hour by hour.
And I'm going to explain the hormonal machinery behind each step. So you can save yourself
an ER visit. However, remember if your blood sugars are not coming down, don't force it.
You know, sometimes there may be other reasons. So this is not a medical advice, just general
information. So when you understand why something works though, you actually do it, right? So let's
go and let's try to understand how this works. So the first thing you do is the hardest thing,
right? So you may be hungry, but you need to stop eating. Not forever though, just for now. And
here's what happens the moment you stop eating. First of all, blood glucose stopped rising from
food intake. It can still go up from the liver, gluconeogenesis and whatnot, but that's pretty
obvious that you should stop eating, right? And at that point, your insulin may start to fall
because insulin resistance keeps it high. Now within two to three hours of your last meal,
insulin levels begin dropping. And insulin is a key hormone here, not just for moving glucose
into cells, but for everything that follows. Now, obviously if you are very insulin resistant,
you know, you don't necessarily want insulin drop. You want insulin drop because your blood
sugars are dropping, okay? Now when insulin drops, your pancreas releases more glucagon.
And the problem is glucagon is insulin's opposite. It tells the liver to stop storing
and start burning. So the liver begins pulling glucose out of storage. So as glycogen, and
obviously it wants to burn through it. Now, here's where most people make the mistake. They
stop eating, but they drink, for example, juice or a sports drink or a sweetened coffee. Well,
that's not really a fancy. That is a glucose IV drip. So water only. Black coffee is fine,
but it can also spike the blood sugar in some sensitive individuals, especially in the morning.
Plain tea is okay, but nothing with sugar, nothing with fructose, nothing that triggers
the insulin, okay? Give your body four to six hours of true fasting and watch what happens to
your numbers while you're staying hydrated with water. The next hour, we're going to do something,
right? We're going to do the walk that changes everything. So 20 minutes after you stop eating,
go for a walk, not for a run, just a walk. This is one of the most powerful blood sugar
interventions that exist. If you cannot walk, you can do a sitting exercise, but you need to
get your heart rate up and start using your muscles. It doesn't have to be lower body.
It can be upper body as well. And it costs you nothing, right? And here's the physiology.
Inside your muscle cells, there are glucose transporters. They are called glut4. Normally,
glut4 transporters need insulin to move to the cell surface to pick up glucose. Insulin acts
like a key that unlocks the door so glucose can enter the muscle. But during muscle contraction,
even gentle contraction like walking or repetitive low weight lifting, glut4 transporters
move to the surface on their own. So no insulin required, right? So your muscles become glucose
sponges totally independently without waiting for your pancreas. Now, obviously, a 20-minute
walk after a meal can clear almost 30 to 50% of glucose from the bloodstream compared to
sitting still. That's not a small effect, right? That's a significant hormonal bypass. And here's
what makes it even more powerful. So low intensity exercise burns primarily fat for fuel, not
glucose. So your muscles are pulling glucose out of the blood, but they are not burning it as their
primary fuel. They are storing it as glycogen. That means the glucose clearing effect lasts
longer. You're essentially draining the tank. Now, I said don't run. Here's why that matters.
Because high intensity exercise actually triggers cortisol and adrenaline, right? Cortisol is a
glucocorticoid. It literally raises your blood sugar. That's why a lot of people are like,
hey, why is my blood sugar going up when I exercise? Well, because your exercise capacity
is not good, and maybe you're forcing yourself too much or more intense than usual, then that
can spike the blood sugar, which is OK. If your blood sugar is not high, typically, if it is just
spiking for an hour and comes back down and stays low, then you're good. You don't have to worry
about it. The problem is if your blood sugar is already running 200, 300, and now you start running,
that may actually spike to 400, 500, right? Because adrenaline tells the liver to dump stored
glucose into the bloodstream immediately. So if you sprint to lower your blood sugar, you may think
that you're helping yourself, but you may actually spike it first, and that's very disappointing.
Now, we said walk or do any exercise that is slow and steady, 15 to 20 minutes. Do it, you know, if
you can do it after every meal, that would be great. Now, by fourth hour, I would say your liver is
doing something right now, right? Let's talk about this organ that nobody thinks about when they
think about blood sugar, the liver, right? Your liver is the master regulator of blood glucose.
It's like a central bank for money, OK? It's not your pancreas. The pancreas produces insulin, but
the liver decides what to do with it. And here's how it works in a healthy person. So after a meal,
blood glucose rises, that's normal, and insulin goes up with it. The liver receives that insulin
signal and does two things. One, it stops producing new glucose because there's no need anymore,
and that's called suppression of hepatic glucose output. Number two, it starts storing excess
glucose as glycogen. So in a healthy liver, this happens pretty smoothly. So blood sugar peaks
mightily and comes back down within an hour. Now, here's what happens in a damaged liver,
right? So like fatty liver, very common in prediabetics or diabetics as well, insulin
resistant people. But the liver becomes insulin resistant. It stops responding to insulin signals
to shut down glucose production. So even when insulin is high, even when blood sugar is already
elevated, the liver keeps making more glucose. This is called hepatic glucose overproduction,
and it is one of the primary drivers of high fasting blood sugar in type 2 diabetes. So you
wake up at 1.30, having eaten nothing since 7 p.m., that's your liver, the 1.30 blood sugar,
right? So you may be like 100 before you go to bed and you wake up at 1.30, 1.50, that's your
liver. Not your diet, not your pancreas. Your liver is insulin resistant in this case. And
it's running on autopilot, dumping glucose into your blood pretty much all night. So how do you
fix the liver fast? Well, two things work pretty quickly. First, remove fructose completely today,
right now. So fructose is processed exclusively by the liver. Every gram of fructose you eat
goes directly to the liver and only the liver. When the liver is overwhelmed with fructose,
it converts into fat, that excessive fructose. That fat accumulates inside the liver cells,
and a fatty liver is an insulin resistant liver. So studies show that removing fructose for as
little as 9 days produces measurable reductions in liver fat. Just 9 days. As of today, no juice,
no soda, no honey, no agave, no fruit in large amounts. Nothing with high fructose corn syrup
for sure. Give your liver a break and it will start responding to insulin again. Secondly,
the fasting you started in hour zero is already healthy, all right? So don't forget about that.
So when insulin drops during fasting, the liver shifts from fat storage mode to fat burning mode.
It starts oxidizing the fat that has been accumulating inside of the cells. The liver is
literally cleaning itself out. This is why fasting is one of the fastest interventions for a fatty
liver and hepatic insulin resistance. And you're already doing it. So keep going. Now we are by
hour six now, right? The hormone your doctor may never check. I'll tell you what that is.
Nobody tells you this, including your doctor. Your blood sugar is actually not the problem.
It is the symptom. The real problem is insulin, right? Specifically too much of it for too long.
Let me show you what I mean. Imagine two patients. Both have fasting glucose of, let's say,
92 milligrams per deciliter. Both are told they're normal. Patient A has fasting insulin of four.
That is great. The body is maintaining blood sugar easily with minimal hormonal effort,
in this case insulin, right? Patient B has fasting insulin of 18. That is four times higher. The body
is working four times as hard to maintain the same blood sugar level. So patient B is not normal.
Patient B is compensated. The cells are resisting insulin. The pancreas is overproducing to compensate.
And this has been going on for years. So patient B is pre-diabetic actually. They just don't know
it yet or they will be pre-diabetic pretty soon. This is a silent phase of insulin resistance.
It can last 10 to 20 years. Blood sugars look all fine, but insulin is screaming. And nobody,
well I wouldn't say nobody, but a lot of doctors don't check insulin. And don't blame your doctor
because your doctors are basically trained to fix obvious clear problems. Like there are rules like,
okay, fix the glucose if A1C is over seven, right? This is what the guidelines say. This is
what insurance wants, yada, yada, yada. So our healthcare is not about optimizing our health.
Our healthcare is sick care. The doctors are trained to treat sick. Doctors are not trained
so much or they're not paid for at all for training or educating their patients to prevent
disease. Insurance will pay 100 grand, 200 grand for a heart surgery, but they're not going to pay
a doctor talking about weight loss for like 30 minutes. They will pay nothing. They'll say,
oh, weight is not a disease. That's what they're going to say to the doctor, right? So it's a
problem, big problem. But the insurance is, if you think about insurance, insurance is not there to
give you a healthy life. Insurance is there when something disastrous happens. So you are primarily
responsible for your own health. Don't rely on your doctors to keep you healthy. Doctors are
there to fix the problems that already exist. Your fasting insulin is above eight, right? If you're
fasting, fasting insulin is above eight. You have basically meaningful insulin resistance at this
point, regardless of your glucose. So if it is about 15, you are significantly insulin resistant.
If it is about 25, your pancreas is in pretty much overdrive and your cells have largely stopped
listening. There's also a calculation, right? We call it HOMA-IR. They, you know, take your
fasting insulin glucose, for example, multiply by your fasting insulin, divide by 405. So under one
is optimal, about 1.9 is early insulin resistant, about 2.9 is significant. Most people walking
around with normal blood sugar actually have a HOMA-IR of three to four. Ask your doctor for a
fasting insulin test. If they push back, you know, then maybe get a second opinion or, um, or do
something about it, right? Now back to today, every hour you fast, insulin continues to fall. That's
good. HOMA-IR is improving in real time. And this is not abstract. This is measurable. This is
happening in your body right now. Now we are by hour eight. So I'm hoping your blood sugar is
already down. So we're going to tell you eat this and not that. So you've been fasting for hours.
You are going to eat soon, right? Because you're getting hungry. When you eat in the next meal,
will either continue the recovery or what you will eat will either continue to recovery or
basically undo everything. So here's the framework. Eat protein first. Protein has a modest effect on
blood sugar, but it has a powerful effect on what happens next. So when you eat protein before
carbohydrates, you slow gastric amputate. That's important. So food leaves the stomach more slowly.
Glucose enters the bloodstream also more gradually. So insulin spike obviously is
blunted. There's also a gut hormone called GLP-1, glucagon-like peptide one. You've heard
of ozempic, right? Well, that's a GLP-1 drug, but your gut produces GLP-1 naturally when you eat
protein and fat. GLP tells the pancreas to release insulin in proportion to the glucose coming in,
not excessively. It suppresses glucagon after meals and it slows the gastric amputee. So it signals
the brain that you're full, which are great. So eating protein activates your body's own GLP-1
system if it is still intact. Sometimes, you know, we still give these prescriptions because
no matter what the patient do, their blood sugar remains high. So then at this point,
we're going to do something, right? If someone is exercising, eating well, eating protein, fat,
and their blood sugars are running high, you're not just going to sit down and watch, right?
You're doctors. We're going to do what we're going to do. So obviously at this point, if you are still
making the GLP-1, you're doing what I'm saying here, your GLP will be activated and no prescription
required. So eat fat with your meal. Fat has almost zero effect on blood sugar unless it's
saturated fat. Some saturated fats can make insulin resistant, but fatty acids themselves
cannot become glucose. That's true. They cannot become fructose either. The only glucose-related
component of fat is the glycerol backbone of triglycerides, which is about 5% of the caloric
content. And that conversion happens pretty slowly hours later in small amounts. So a meal of eggs
and grass-fed beef, for example, and non-starchy vegetables will barely move your blood glucose.
Compare that, for example, to a bowl of oatmeal with fruit and honey, which every people tend
to think that's very healthy, which will spike you within pretty much 30 minutes and then maybe
even crash you within two hours. So basically avoid all starch today, especially when you're
running high. Starch is not complex. That is a marketing term. Starch is glucose molecules
linked together in chains. So the moment amylase, the enzyme in your saliva, hits the starch, it
starts breaking those chains apart. By the time starch reaches your small intestine, it is already
becoming free-floating glucose for you. Bread, rice, pasta, potatoes, corn, all of them hit the
bloodstream almost as fast as pure sugar. Today is not the day for any of them, okay, because we
are trying to lower the blood sugar. So we're going to eat eggs, meat, preferably fish, you know,
more than the red meat, but leafy greens, broccoli, cauliflower, avocado, olive oil, and nuts. We're
going to avoid bread, rice, pasta, potato, fruit juice, anything processed, anything with a label
that lists sugar in the first three ingredients or carbohydrates or starch. So eat once or twice
today, not three times, and I want you to start passing, you know, the first eight hours. Because
every meal raises your blood sugar, right? Fewer meals means fewer glucose spikes. Fewer glucose
spikes means, you know, less insulin needed to fall, to reduce the blood sugar between meals.
This is the entire logic of intermittent passing, and it works. Now we are at hour 12 right now, and
we have a cortisol problem. So you're halfway through the 24 hours, you're still going, you're
still lowering your blood sugar. Here's something that can undo all of it, right? Stress, right?
Cortisol is your primary stress hormone. It is produced by the adrenal glands, which are small
glands that sit on top of your kidneys. They're very important for survival, you cannot go without
them. But cortisol is a glucocorticoid, so when it rises too much, your blood sugar will rise with it,
right? Every time, every day. And here's the mechanism. Cortisol tells your liver to produce
more glucose through a process called gluconeogenesis, making new glucose from amino
acids and glycerol. It also makes cells more insulin resistant. It blocks the insulin signaling
at the receptor level, at the insulin receptor. So chronic stress means chronically elevated cortisol,
which means chronically elevated blood sugar, which means chronically elevated insulin, which
basically accelerates your insulin resistance. So you cannot out diet chronic stress, okay? So I've
seen patients eat perfectly, they eat low carb, they do intermittent passing, they have no sugar in their
diet, but they still have elevated fasting glucose. Every single time, when we dig deeper, there is a
cortisol problem. It could be a high stress job, it could be poor sleep, it could be a relationship
conflicts, it could be financial anxiety. A lot of things can happen, right? So HPA axis, which is
the hypothalamic pituitary adrenal axis, is directly wired into your metabolic system. So today, right
now, do something about cortisol. So what can you do? Well, a 10 minute walk outside or go for a bike
ride, not necessarily for exercise, just to reduce your cortisol, just the nature, right? Expose
yourself to nature, to the sunlight, because, you know, sunlight on your skin triggers serotonin.
Both reduce HPA axis activation. So, and you're going to do box breathing too, right? Four seconds in,
four seconds hold, four seconds out, or you can do eight seconds in, eight seconds hold, two seconds
out. That activates your parasympathetic nervous system and it works almost immediately, okay? So
if you're stressed out, try that and see how it goes. It directly counters the cortisol response
and cold water on your face or a brief cold shower activates the vagus nerve and actually
reduces the cortisol. So there are, well, these are, I would say, not soft suggestions. These are
important stuff. These are physiological interventions. So at least do one of them right
now, okay? Now, hour number 16. I'll tell you this, sleep is a drug. It's a metabolic drug. And here's
the one what most people just ignore, right? They're asleep or they think they're sleeping
okay, but they don't. But one night of poor sleep under six hours reduces insulin sensitivity by
25%, just one night. The mechanism is direct, right? Because sleep deprivation raises the cortisol
and cortisol raises blood sugar. It also increases ghrelin, the hunger hormone, and decreases leptin,
the satiety hormone. So you wake up basically insulin resistant with elevated blood sugar.
You're already craving carbohydrates. You're reaching out for cookies and stuff or maybe,
you know, muffins, whatever you see. And then people wonder why they cannot stick to a diet.
It's not about willpower. It is your hormones. But here's the flip side.
One night of good sleep, like seven to nine hours, measurably improves your insulin sensitivity
because growth hormone is released in pulses during deep sleep, right? So growth hormone
promotes fat burning and muscle repair. It promotes cellular insulin sensitivity. Melatonin,
your sleep hormone, has direct antioxidant effects on pancreatic beta cells, the cells
that produce insulin. So poor sleep basically damages beta cells over time. Good sleep protects
them. Tonight is basically part of your 24-hour protocol, all right? So get to bed early,
keep the room cold around 65 to 68 degrees Fahrenheit, block all night, no screens for 30
minutes before bed. And this is not optional. This is the final piece of 24-hour reset.
Now we are at hour 20. What about the supplements worth taking today to lower your blood sugar
today? So I'm going to give you three supplements. That's it, not 20 of them, okay? Now one of them
is berberine, or even better, dehydroberberine, right? It activates AMP kinase, adenosine
monophosphate-activated protein kinase. As you know, AMP kinase is the master metabolic switch.
When it's activated, muscle cells pull in more glucose and the liver reduces glucose production.
And insulin sensitivity improves. Multiple randomized controlled trials show that the
berberine or dehydroberberine, superberberine, they reduced fasting glucose and AML-C comparably
to metformin. Now 500 milligram, two to three times daily for regular berberine, and 250
milligram for dehydroberberine. It works within hours, not weeks. Now another one is magnesium.
Magnesium is required cofactor for insulin receptor signaling. Without adequate magnesium,
insulin cannot really bind properly to insulin receptor. The signal definitely doesn't transmit
when that doesn't happen, right? So glucose does not enter the cell efficiently. So over 80% of
people with type 2 diabetes, by the way, are magnesium deficient. And here's the vicious
cycle. You know, the high blood sugar causes kidneys to excrete more magnesium. So high
blood sugar basically depletes the magnesium, and the magnesium deficiency basically worsens
your insulin resistance. Magnesium glycinate, I will say, is the best, right? 300 to 400
milligram before bedtime is going to improve your sleep quality, all right? And it also
improves your insulin sensitivity, which lowers your blood sugar. It's only one supplement,
but has multiple mechanisms. And the next is apple cider vinegar, right? This one has the
most clinical evidence for acute blood sugar lowering. Why? Because the acidic acid in apple
cider vinegar inhibits alpha amylase and alpha glucosidase. These are the enzymes that break
down starch into glucose. Now slower starch breakdown means, basically, slower glucose
entry into the bloodstream. It also improves insulin sensitivity in the muscle tissue. So one
to two tablespoons in a large glass before your largest meal. So studies show that it can reduce
post-meal glucose by 20 to 30, 30, 35%. That's pretty significant, right? That's a real effect.
Now we are at hour 24. So what happened in your body so far? Let's recap. What you actually did
in the last 24 hours? So you stopped eating, and you let your glucose fall, and your insulin
start to come down. Your liver shifted from glucose production to glucose burning. Glycogen
stores began depleting. So you walked after meals as well. So your glucose transporters activated
without insulin, and your muscles pulled glucose out of the bloodstream independently. And you
removed fructose, right, from your diet. So your liver stopped being flooded. It began oxidizing
the stored fat. And hepatic insulin resistance started basically reversing. And you ate protein
and fat, not starch, no sugar. And insulin stayed low between meals, right? And the glucagon rose.
So fat burning continued. You managed cortisol. Your HPA axis calmed down. Your gluconeogenesis
slowed. Your liver stopped dumping emergency glucose. And you slept. Growth hormone pulsed.
Beta cells recovered. Insulin sensitivity improved at the cellular level. This is not
one thing working. Do you realize? This is six hormonal systems working together, basically all
pointing in basically the same direction. And here is what that looks like on a glucometer.
So you started at 220 this morning. You could realistically be at 140 to 160 by tonight.
And if you started at 160, you could be down to 95 to 100 next morning.
Not because of a drug, because you stopped blocking your own biology. Now I need to tell
you something important. The number on your glucometer is definitely not the full story.
And it never was. Blood sugar is a controlled variable, right? It's a controlled variable.
Your body defends it aggressively. It will sacrifice everything else to keep glucose in
a narrow range. It will pump out more and more insulin for years, decades, and the whole time
your glucose looks just fine. And this is the trap. The real number is insulin, specifically
fasting insulin. If your fasting glucose is 92, but your fasting insulin is 19, you're not healthy.
You're compensating. Your pancreas is working four times harder than it should. And that
compensation basically has a time limit. When the beta cells in your pancreas finally exhaust,
well, when the pancreas can no longer keep up with that demand, basically, glucose starts rising.
And your doctor says, you have diabetes. I'm sorry. And here's something important for you.
But the diabetes did not start last week. It started 15 years ago. Same physiology,
same biology. When insulin first began climbing, finally, that was years ago,
the test that would have caught, that basically cost less than $30. The fasting insulin,
so ask for it. Demand it. Calculate your HOMA-IR. Fasting glucose multiplied by fasting insulin
divided by 405. That's it. Okay. Under one is normal. Above 1.2 is early insulin resistance.
Above 2.9 is significantly insulin resistance. So act now. This number will tell you
where you actually are, where you stand, not where your glucose is or pretends that you are.
And here's the honest truth. What you did today moved the needle fast, but insulin resistance took
years to build. The liver did not become fatty overnight. The muscle cells did not down-regulate
their insulin receptors in a week. So 24 hours basically resets the direction. It does not
erase the history. Think of it like a tanker ship, right? You turn the wheel, the ship is now
pointing the right way, but it takes time to change course completely. And here's what the
timeline actually looks like. In 24 to 48 hours, fasting glucose drops. Post-meal glucose spikes
reduce and insulin begins falling. In one to two weeks, liver fat begins measurably decreasing
and fasting insulin drops noticeably. Energy stabilizes. In four to eight weeks, HOMA-IR
improves significantly. Avon C begins moving. Triglycerides drop. HDL rises,
which are all good stuff. In three to six months, meaningful reversal of insulin resistance can
take place. And some people come off the medication entirely under medical supervision
because your body wants to heal. It is designed to heal. You just have to stop doing the things
that basically prevents that healing. One thing that undoes everything though, and I want to
leave you with this, you can do everything right. Fast, walk, sleep, eat clean, take berberine,
whatever. One thing will undo all of it, all of it. Going back to processed carbohydrates and
fructose the next day. Not because one bad meal destroys you, but because, because of it, what it
does that meal to your mindset. The people who reverse insulin resistance permanently are not
the ones who had the most willpower. They are the ones who understood the mechanism deeply enough
that they stopped wanting the thing that was hurting them, no matter how delicious it was.
So when you understand that a can of soda is directly flooding your liver with fructose,
building fat inside your liver, impairing the organ that regulates the blood sugar, basically
you stop seeing it as a treat. You see it as what it is. When you understand that a bowl of white
rice spikes your blood sugar faster than table sugar, it triggers an insulin response that pushes
your cells further into resistance. You stop calling it a healthy carb, right? You see it as
what it is. The knowledge is the intervention, not just for today, for every meal after this as well.
