The Claim
In animals subjected to total starvation or a carbohydrate-poor diet followed by carbohydrate refeeding, liver glycogen levels rapidly increase to supernormal values ranging from 424 to 624 mmol glucosyl units per kg wet liver tissue.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When animals are deprived of food or carbohydrates and then given carbohydrates again, their liver stores a large amount of glycogen, reaching levels between 424 and 624 mmol glucosyl units per kg of liver tissue.
See the scientific wording
In animals subjected to total starvation or a carbohydrate-poor diet followed by carbohydrate refeeding, liver glycogen levels rapidly increased to supernormal values ranging from 424 to 624 mmol glucosyl units per kg wet liver tissue, indicating a robust capacity for glycogen resynthesis following prolonged carbohydrate deprivation.
When carbs return after a long period without them, the pancreas releases a lot of insulin. This insulin tells liver cells to take in glucose from the blood and turn it into glycogen storage molecules at maximum speed. The liver fills up with more glycogen than normal because the system is reset to store as much as possible after being empty.
What the research says
1 studyWhen people went without food or carbs for a while and then ate carbs again, their livers stored way more energy (glycogen) than normal — exactly what the claim says. The study measured this and found the same numbers.
