The Claim
During brief starvation in healthy men, decreased insulin levels drive the adaptation of peripheral tissue metabolism by promoting amino acid mobilization from skeletal muscle to support gluconeogenesis.
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 healthy men undergoing short-term fasting, lower insulin levels cause amino acids to be released from muscle tissue to produce glucose.
See the scientific wording
The adaptation of peripheral tissue metabolism during brief starvation in healthy men is primarily driven by decreased insulin levels, which promotes amino acid mobilization from skeletal muscle to support gluconeogenesis.
When food is not eaten, insulin levels drop, which tells muscle tissue to break down its proteins into amino acids. These amino acids flow into the blood and go to the liver, where they are turned into glucose to keep blood sugar stable.
What the research says
1 studyStudy: Effects of brief starvation on muscle amino acid metabolism in nonobese man.
When people don’t eat for about 2.5 days, their muscles start releasing more amino acids to help make glucose, and this study shows that the main reason is because the hormone insulin drops — not because of other signals.
