ZOE Science & Nutrition · How to eat sugar without gaining weight (crush your cravings and end energy crashes) | Prof Tim Spector & Prof Sarah Berry · 23 Jul 2026 podcast

But we just didn't think at that point, oh, what was I doing three hours before?

And this is why it's important that we understand the science.

Well, I don't think we should view mental health as being very different to just another organ in the body.

The brain is there.

The brain sucks up 20, 25% of our energy and

it's only 5% of our weight.

So it's the most energy-hungry organ in the body.

So it's super sensitive to what it's getting as its energy source.

And if you deprive it

You know, you give it too much or too little, that will stress the system.

But we do know that when you're having repeated really high sugar spikes in the blood, that stimulates the immune system to create inflammation, which is just sort of dialing up the thermostat on your immune system.

And that then travels from your gut to your brain via the vagus nerve.

And you've got immune cells in your brain, and they will pick that up, this inflammation.

And that has been shown to be associated with a whole range of mental and brain disorders, everything from slight cognitive loss, Alzheimer's, to depression, and even schizophrenia.

we know that the way glucose is controlled is very much linked to our immune system and that's linked to all these kinds of diseases.

And they all come back to controlling those key systems in our body and making sugars and glucose a really key factor.

That's correct, yes.

Lots of data now linking not only type 2 diabetes with Alzheimer's, giving you a three or four times risk over a lifetime, but also diabetes.

poor diet related to sugar intake, sodas, free sugars, increasing risk of these as well in observational studies, but still there's a lot of them.

So it does start to make sense once you start understanding the mechanisms that your brain is very sensitive and that by changing the environment of the immune system, you will change
