The Claim
In skeletal muscle of male C57BL/6 mice, 16-hour daily intermittent fasting for four months is associated with upregulation of proteins involved in pyruvate metabolism, fatty acid biosynthesis, and AMPK signaling, and downregulation of proteins involved in oxidative phosphorylation and thermogenesis.
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 subjected to 16-hour daily fasting for four months, skeletal muscle shows increased levels of proteins related to pyruvate metabolism, fatty acid production, and AMPK signaling, and decreased levels of proteins involved in oxidative energy production and heat generation.
See the scientific wording
In skeletal muscle of male C57BL/6 mice, 16-hour daily intermittent fasting for four months is associated with upregulation of proteins involved in pyruvate metabolism, fatty acid biosynthesis, and AMPK signaling, and downregulation of proteins involved in oxidative phosphorylation and thermogenesis, suggesting a shift toward energy conservation and lipid-based fuel utilization.
When food is not available for 16 hours each day, the body runs low on sugar and starts using fat for energy instead. Muscles stop burning sugar with oxygen and make more proteins that store and break down fat. A key energy sensor turns on and tells the cell to save energy by turning off heat production and reducing the activity of the power plants inside cells. This lets the muscle survive longer without food by using fat as fuel and not wasting energy.
What the research says
1 studyIn male mice that fasted 16 hours a day for four months, their muscles changed to use fat for fuel instead of burning sugar with oxygen, and they made more proteins that help store fat and save energy — just like the claim says.
