Why is it so difficult to give up sugar?

Again, I always think this is a trifactor when it comes to sugar addiction.

And that is biology and physiology is number one.

Two, it's societal.

And three, it's now the chemical components to what we're eating a lot of.

But if we start with the reason why it's really hard to stop sugar, there was a very famous experiment research study done by the University of Bordeaux in 2007.

And that was on rats who were given sugar water.

So what other hacks or what other tips have you got for people of where, what they can do? What sorts of things should they be eating?
