☕ Your morning coffee may be doing more than waking you up… it could be quietly raising your blood sugar before you even take your first bite of food.
Most people think glucose spikes only happen after eating carbs or sugar. But what if your black coffee alone is enough to send your glucose monitor soaring?
In this eye-opening video, we will explains the hidden connection between caffeine, cortisol, adrenaline, insulin resistance, and blood sugar spikes — especially in the morning.
You’ll learn why: 🔹 Coffee can trigger your “fight or flight” hormones 🔹 Adrenaline causes your liver to dump glucose into the bloodstream 🔹 Caffeine can temporarily reduce insulin sensitivity 🔹 Morning cortisol levels already put your body in a glucose-raising state 🔹 People with prediabetes or type 2 diabetes may react even more strongly to caffeine
We will also breaks down real scientific studies showing how caffeine affected blood sugar levels in people with diabetes — and why your CGM readings may suddenly make sense.
But this isn’t about quitting coffee.
You’ll also discover practical strategies to reduce glucose spikes WITHOUT giving up your favorite morning ritual, including: ✅ Best times to drink coffee ✅ What to eat before caffeine ✅ How fasting changes the effect ✅ Smart ways to stabilize blood sugar naturally ✅ Common mistakes people make every morning
If you’ve ever wondered: • “Why is my blood sugar high when I haven’t eaten?” • “Does black coffee spike insulin?” • “Why does my CGM rise after coffee?” • “Is caffeine bad for diabetes or prediabetes?”
…this video is for you.
Watch until the end to learn how to keep your coffee AND improve your glucose control at the same time.
👇 Tell us in the comments: Have you ever noticed a blood sugar spike after coffee?
You wake up, you haven't eaten a single thing, and your blood sugar is already climbing.
No breakfast, no juice, no snacks, just coffee. And your glucose monitor is going crazy,
especially if you're already cesium, right? So you're not imagining it, coffee is doing that,
right? And I'm going to explain exactly why, and more importantly, how to fix it without giving
up your coffee. Obviously Dawn Phenomenon is a problem, and a lot of people may have it without
the coffee, but coffee just exaggerates the problem a lot more. Because I know you're not
giving it up, right? The coffee? More than likely not. My patients never do. But I'll give you some
tips. So as you know, I'm Dr. Ergen, you're a Necronologist, so let's get into it. So here's
coffee is actually doing to you. So coffee triggers your adrenal glands to release
adrenaline. That is a fight or flight. So your body thinks something exciting or dangerous
is happening. So it dumps glucose into your bloodstream for quick energy. But here's the
problem. Adrenaline also blocks insulin from doing its job. So now you have rising blood sugar
and a blocked insulin. That is a double hit before 8am. And there's more. Caffeine blocks a molecule
in your body called adenosine. Adenosine plays a big role in how much insulin your pancreas
produces. Block it and insulin output drops. So blood sugar climbs higher, right? So one study
gave people with type 2 diabetes 250 milligrams of caffeine, roughly two cups of coffee with
breakfast and lunch. And their blood sugar ran easy, 10% higher all day compared to caffeine
days. And the biggest spike is obviously in the morning after first drinking it. Not a little
higher, 10% is a big number. Now, here's what makes mornings especially brutal. Your body,
like I said, already naturally spikes the cortisol and adrenaline when you wake up,
which we call cortisol awakening response. So coffee on top of that, you're basically
pouring gasoline on a fire that was already burning. So should you quit coffee? Absolutely
not. Here's what you should actually do. Number one fix I would say, stop using Robusta beans.
Most people have no idea that there are two types of coffee beans, Arabica and Robusta, right?
Robusta has twice the caffeine of Arabica, twice. And guess what is stuffed inside most cheap
grocery store blends and a lot of espresso? Robusta. So switch to 100% Arabica. It is labeled
right on the back. This one change right there alone, cuts your caffeine load significantly
while keeping the taste you love, just switching that type. Now, if your espresso blend does not
say 100% Arabica, it probably is not. Fix number two, go darker. Dark roast coffee contains less
caffeine than light roast when measured by the scoop. And here's why. Dark roasting expands the
The bigger the beans, the fever fit in your scoop. Less caffeine per cup. It is not a dramatic
difference, but every bit counts. Plus dark roast tastes pretty good. Now, number three fix or third
fix is cold brew. That's your best friend. Cold brew contains 30% less caffeine than regular
drip coffee. You make it by soaking coarse grounds in room temperature in the water overnight,
obviously, straining it and storing it in the fridge for two weeks. Very good. So you don't
have to make coffee every morning. It is low acid, very smooth and easy on your stomach.
So people who try almost always stick with that. So why not give it a shot? Fix number four for you
is make the Americano trick. Basically work for you. Trick is already there. So order or make a
single shot espresso, which is only 50 to 64 milligrams of caffeine, and then add four to
five ounces of hot water. So a splash of cream. That's it. You have a full mug of coffee for a
Most people cannot even tell the difference in a blind taste test.
Fix number five, brew it short. A longer brewing time equals more caffeine extracted, period.
Espresso is brewed fast, despite what people think it is actually lower in caffeine per serving
than drip coffee. So slow drip coffee sits in contact with the water the longest and
pulls the most caffeine out. So if you are using a drip machine, shorten the brew or reduce your
grounds slightly. Fix number six, walk after you drink it. This one is free, right? It requires
zero changes to your coffee routine. Take your coffee and go for a 15 to 20 minute walk. Your
muscles will absorb the blood sugar directly. No insulin is needed. So the adrenaline spike from
coffee actually becomes useful when your muscles are moving. So you are working with your biology
instead of against it. This alone flattens that morning glucose spike significantly.
Now fix number seven, eat protein first. If you're going to sit and drink your coffee,
I would say eat something high in protein, such as eggs, Greek yogurt, cottage cheese.
This protein slows glucose absorption and blunts the insulin resistance effect from caffeine.
A high fat, high protein meal changes everything about how your body handles that early caffeine
hit. Bottom line, coffee doesn't have to be your enemy. You just need to be smarter about that
the bean that you're using, the way you're brewing it, and what you're doing right after you drink it.
So arabica beans, dark roast, cold brew, walk after. Eat protein and stack those five things
and your morning blood sugar will look completely different within a week. Dr. Ahmed Ergin,
now please go make a better cup of coffee for me and maybe one day we'll drink it together.
See me in Port Samuel City, Florida in my practice. Talk to you later.
