The Claim
In the liver of male C57BL/6 mice, 16-hour daily intermittent fasting for four months is associated with upregulation of proteins involved in fatty acid oxidation, ketogenesis, and glycan degradation, and downregulation of proteins involved in steroid hormone synthesis and cholesterol metabolism.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In male C57BL/6 mice, daily 16-hour fasting for four months increases liver proteins that break down fats for energy and decreases proteins that build steroids and cholesterol.
See the scientific wording
In the liver of male C57BL/6 mice, 16-hour daily intermittent fasting for four months is associated with upregulation of proteins involved in fatty acid oxidation, ketogenesis, and glycan degradation, and downregulation of proteins involved in steroid hormone synthesis and cholesterol metabolism, indicating a tissue-specific shift toward energy mobilization and away from anabolic processes.
When the liver runs out of stored sugar during daily fasting, it switches from building cholesterol and hormones to burning fat and making ketones for energy. This change happens because the liver starts breaking down fat from body stores, turns it into ketones, and stops making cholesterol and steroid hormones. At the same time, the liver reduces protein breakdown to protect itself, while other tissues like muscle and brain use the ketones and break down their own proteins to survive.
What the research says
1 studyWhen male mice fast for 16 hours every day for four months, their livers start making more proteins that burn fat and make ketones for energy, and fewer proteins that build cholesterol and hormones — like switching from building things to using up stored fuel.
