How intermittent fasting changes liver enzymes and helps prevent disease: Research on mice reveals surprising impact on fat metabolism -- ScienceDaily

"For the first time we showed that HNF4-(alpha) is inhibited during intermittent fasting. This has downstream consequences, such as lowering the abundance of blood proteins in inflammation or affecting bile synthesis. This helps explain some of the previously known facts about intermittent fasting," Dr Larance said. The researchers also found that every-other-day-fasting -- where no food was consumed on alternate days -- changed the metabolism of fatty acids in the liver, knowledge that could be applied to improvements in glucose tolerance and the regulation of diabetes.
