Sugar vs. Cocaine: Which Is Worse for Your Brain? – Dr. Berg fast clip

Did you know you can eliminate brain fog and improve cognitive function if you quit sugar? Discover the surprising connection between sugar and brain health and the amazing benefits of cutting out sugar. WHY SUGAR IS MORE HARMFUL THAN YOU THINK:

Sugar creates similar effects to cocaine and heroin in certain parts of the brain. In one study, if given a choice, a lab rat will go after sugar instead of cocaine! Sugar can alter your hormones and put you in a state of anxiety. It can even cause a mild form of dementia, leading to forgetfulness and memory loss. Sugar affects the hippocampus, which controls memory. The brain can run on glucose, but too much glucose can eventually hinder absorption. You only need one teaspoon of sugar in your blood at one time, but people consume much more than that! Excess sugar is stored as fat. Over time, high sugar consumption can lead to insulin resistance, depriving the brain cells of the energy they need.

People often consume way more sugar than they know in beverages like juice or due to hidden sugar in the form of starch. A low-carb diet creates the most benefits for your health. It can reverse diabetes in 10 weeks! You’re no longer feeding your brain glucose when you’re on a low-carb diet. A low-carb diet forces the body to mobilize ketones to feed your brain. Once you quit sugar, you’ll notice an improved mood, better concentration and attention, a better ability to learn, improved memory, and brain fog will be gone. Cutting carbs and quitting sugar will leave many people hungry, unsatisfied, and craving certain foods. The solution is to increase protein! Sufficient protein and fat can help eliminate cravings and decrease the desire to snack. There are also plenty of healthy substitutions that can make it easier to quit sugar. You do not need to consume sugar to maintain healthy blood sugar levels. Your liver can create sugar from other food sources.

63 and have been low carb for a year and a half now. Lost 50 pounds and in the best shape of my life. Not on any meds. Energy all day long with clear thinking. Stopped eating processed foods, seed oils and sugar. I found the real fountain of youth. – Countryboy62
One additional layer worth noting is how advanced glycation end products (AGEs)—formed when excess sugar binds to proteins—can contribute to neuroinflammation and accelerate brain aging. The hippocampus, which is sensitive to both oxidative stress and insulin resistance, suffers early in this process. This is why managing blood sugar isn’t just about diabetes—it’s about preserving long-term cognitive health. – Dr. H
Excellent breakdown. The connection between excessive sugar intake and cognitive decline is more profound than many realize. The effects on the hippocampus, memory, and even mood regulation are well-documented, especially in the context of insulin resistance. Reducing added sugars—especially hidden sugars in starches—is a key step toward improving focus, emotional balance, and long-term brain health.

Keep teaching this, Eric, as people need it drummed into them – Education on Nutrition is so important – Next to it is exercise and a happy, happy outlook, on life even when things go wrong don’t grab that ice bun go for a walk in mother nature and breath in the fresh air – it’s all free and you will feel brilliant if you don’t well perhaps your addiction to sugar get help !!! – David Freeman
I stopped eating sugar 2 years ago. I was not diabetic or obese at all. What I didn’t know is the issue with Starch (which you find in patatos and bread, even with whole bread). So in fact these foods still created glucose. Nobody made it clear to me. I now reduced Potatoes to the minimum. The other big food issue is bread, since a few months I switched to Desem bread. Desem It is fermented yeast. To be honest I enjoy eating more than before. I don’t miss anything. Since I’m a post cancer patient, I found out that glucose love cancer cells. – The Vorst
I grew up drinking those Pepsi and Coca Cola sodas in glass bottles, ngl, that stuff is ambrosia on a hot day. It’s a struggle but I have reduced my intake significantly. Sugar is a tough habit to break. Great topic, Dr. Berg. – Athonite
sugar addict since childhood, 4 yrs ago I would bring home ice cream , I would have a bowl and go back and have another bowl until the whole carton was gone. It was like I couldn’t control myself. Now I only use stevia and monk fruit, cook all my own food, and my A1c is 5.6 with no meds. – Kathy B
I was able to kick sugar out of my coffee, quit sodas and sugary drinks, and snacks from Hostess, but I’m having a hard time with breads & flour tortillas. I know there’s the ability to make healthier options, but I don’t have the resources – Veronike V
