So about 120 grams of the 160 grams is used by the brain. The rest is used by other areas of our body. Now, of course, if you're an athlete, for example, if you're a swimmer and you swim, let's say a double practice, and that that adds up to, let's say, ten k, then obviously you need many more grams of sugar. So those individuals need about 500, 600 grams of sugar. And so what we see is if gluconeogenesis did not actually take place inside our body, the individual would only be able to actually survive for a little longer than a day, because once the preserves of these sugars actually runs out, our cells have no way of creating new sugar molecules from these non sugar components. And in that case, we essentially die.
