well this morning i actually skipped breakfast and uh you know one of the things is you know it turns out that things like carb restriction and intermittent fasting and all these things that people are recommending they're they're pretty effective at losing weight and the carb restriction in particular is a very very helpful because it removes not only sugar but it reduces the amount of starch you're eating and remember the starch can be converted
to fructose. So it turns out that that is a major mechanism of protection. So if you want to lose weight, you know, carb restriction, intermittent fasting are great ways to go. But there's also, you know, what we learned from this is there are a lot of nuances. For example, it's possible to eat cake and not eat and not activate the biologic switch. And the reason is that the way fructose works
to fructose. So it turns out that that is a major mechanism of protection. So if you want to lose weight, you know, carb restriction, intermittent fasting are great ways to go.

But there's also, you know, what we learned from this is there are a lot of nuances. For example, it's possible to eat cake and not eat and not activate the biologic switch. And the reason is that the way fructose works
is it's the concentration that hits the liver. When the fructose concentration in the liver is high, that's when the switch activates. So for example, if I did not want to activate this switch, I could eat a piece of cake. If I could eat a piece of cake slowly, like over a couple of hours, then it wouldn't activate the switch. Now the trouble is, of course,
is it's the concentration that hits the liver. When the fructose concentration in the liver is high, that's when the switch activates.

Now the trouble is, of course,
that our desire to eat the cake outbeats our logic where we know that it's not good. It's just like a soft drink. It's hard to tell a person to just sip a soft drink over two hours or over an hour. Everyone will drink it very quickly and that's the problem. But the truth is when you understand the science, you can actually figure things out. So for example, if you drink water

if you drink more water, you can block the effects of salty foods. So we did this. We took people, we gave them salty soup, and we could show that immediately their blood pressure went up and they activated this switch. We could prove it, that they activated the switch. But if we gave the salty soup with water,

the salt concentration did not go up in their blood, they did not trigger that enzyme, and they did not develop an increase in blood pressure, nor did they activate the switch.

So what we call low glycemic carbs don't activate the switch. So vegetables and all those things, they're very good, even though they contain carbs. So you don't have to carb restrict completely. It turns out that it's certain carbs. It's really only four or five. Sugar. and high fructose corn syrup, I put them together. And then the other big ones are bread, rice, potatoes, and cereal.

And those are the main ones that tend to raise glucose in our blood and activate this switch where the glucose gets converted to fructose.
