The Claim
In male C57BL/6 mice subjected to 16-hour daily fasting for four months, intermittent fasting is associated with a 2- to 3-fold increase in blood ketone levels, a significant reduction in fasting blood glucose and HbA1c, and decreased serum cholesterol.
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 undergoing 16-hour daily fasting for four months, blood ketone levels increase two- to threefold, fasting blood glucose and HbA1c decrease significantly, and serum cholesterol levels decline.
See the scientific wording
In male C57BL/6 mice subjected to 16-hour daily fasting for four months, intermittent fasting is associated with a 2- to 3-fold increase in blood ketone levels, a significant reduction in fasting blood glucose and HbA1c, and decreased serum cholesterol, indicating enhanced metabolic flexibility and improved systemic energy regulation.
When food is absent for 16 hours each day, the body runs out of stored sugar and starts breaking down fat for energy. The liver turns fat into ketones, which replace sugar as the main fuel for the brain and muscles. This lowers blood sugar and cholesterol because the body stops relying on sugar and starts using fat instead.
What the research says
1 studyWhen male mice fast for 16 hours every day for four months, their bodies start burning fat instead of sugar, which makes ketones go up two to three times and lowers their blood sugar and cholesterol — just like the claim says.
