WARNING: High Blood Sugar Shrinks Your Brain (2024 research)

YES! - I Want Healthy Blood Sugar

Recent research shows that your brain can actually “thin out” and start to “dissolve” as you age!

Specifically, overweight people with diabetes see the cortex (your brain) shrivel up in the regions responsible for everything you need for your day-to-day function, including the parts that control memory, movement, visual information processing, and even going to the bathroom.

Scientists have discovered the cause of this “tissue paper shrinkage”, is excess blood sugar, which can rush through your brain and rot out everything it touches.

Overweight diabetics have the highest “brain shrinkage”. However, pre-diabetics and most people who tend to have higher blood sugar levels, are also negatively affected and thus, will have faster “brain shrinkage” as they age.

In another article, I mentioned that Alzheimer’s is now classified as type 3 diabetes. Adding more evidence that high blood sugar negatively affects your brain function.

Now, the good news is that you can reverse this and at the very least, definitely slow the progression of any brain shrinkage due to high blood sugar levels.

Here are 3 simple steps:

Diet For Blood Sugar

You need to reduce or eliminate all sugars, including fruits. Also lower your total carbohydrate intake – such as bread, pasta, rice, grains, etc. Stick to “low glycemic” index carbs – such as legumes, yams, and lots of vegetables.

Add healthy fats into your diet – such as raw nuts, avocados, macadamia nut oil, seeds, coconut oil, and fish oil.

Increase your fiber intake, which helps prevent blood sugar spikes.


You need to move daily. Exercise improves your insulin sensitivity.

And the more muscle you have, the better your body will utilize glucose and sugar and thus, support healthy blood sugar levels.

Try to lift weights 3x weekly so you can gain or maintain your muscle mass. And go for a walk as often as you can.

Herbs & Vitamins For Blood Sugar

There are a handful of supplements that are shown to help support healthy blood sugar and improve insulin sensitivity.

By improving your blood sugar levels, not only will your brain cognition improve, but you’ll also dramatically SLOW down the aging process.

Another benefit of lower blood sugar levels is lower body fat, especially stubborn belly fat.
