It really is there to try to shift the calories we're eating from instant energy to stored energy.

It turns out that our bodies, we have a sort of a shield in our intestine where we inactivate the first four or five grams of fructose that we eat. So it turns out that natural fruits have only small amounts of fructose. And although it's really sweet to taste, we kind of inactivate the fructose in our gut so that we don't actually get a big load of fructose to our liver where everything happens.

And so a natural fruit does not give you enough fructose to activate the switch. Now, if you drank fruit juice, now you're going to get a large load of fructose and you're going to activate the switch. There's another reason too, natural fruits have a lot of fiber.

and they also have vitamin c and other things and it turns out that the fiber slows the absorption and the vitamin c actually helps neutralize the effects of the fructose

When you give animals the exact same number of calories, the weight gain is still a little bit greater with sugar, but there's a major effect, which is that the other metabolic effects of the switch, which is to become insulin resistant and diabetic and develop fatty liver, that still occurs even with controlling, even if you put them on a diet restriction.

So if you put animals on a caloric restriction, so they're eating less than normal, but they get a high sugar diet, they're still gonna become diabetic. They're still gonna get fatty liver. They're still gonna get hypertension. So those things are not driven by the excess calories. Only the weight gain is really driven by the excess calories. You know, that's what drives the weight gain.

But all the other things, you can be skinny and diabetic if you put an animal on a caloric restriction with a high sugar diet.
