Researchers fed overweight volunteers an extra thousand calories of sugary snacks daily in addition to their regular food consumption.19 This sounds like a lot, but it only means ingesting an extra two small bags of candy, a glass of juice, and two cans of Coca-Cola per day. After three weeks, body weight increased by a relatively insignificant 2 percent. However, liver fat increased by a whopping 27 percent, caused by an identical increase in the rate of DNL. This fatty liver was far from benign, as blood markers of liver damage increased by a similar 30 percent.
