Example: If you really want to eat some sugar. 

Let's say, a cookie, a donut, or whatever. 

The best time to eat that sugar so that you have maximum dopamine, from it, maximum pleasure and less impact on your body is going to be after a meal as dessert. 

You want to always avoid eating sugar on an empty stomach and always avoid eating sugar in the morning. 

So breakfast should be savory. Okay, in the morning, nothing sweet. 

Because if you have to eat them in the morning as you digest that sugar, they turn into glucose molecules and these arrive your bloodstream really  quickly and caused what's called a glucose spike. 

So blood sugar spike. And then about 90 minutes later Lewis, your glucose levels are going to drop, feel a crash. And now it's 10 a.m., 11 a.m, and all of a sudden you feel more cravings for sweet foods you like. 

I need a cookie, I need some chocolate, I need a snack, then you spike again. And then you spike again. And then all day you are a roller coaster you feel addicted to sugar.
