The Claim
In female rats subjected to 12 weeks of treadmill endurance training with energy restriction, a high-cholesterol diet does not significantly alter serum progesterone levels compared to a low-cholesterol diet, while serum estradiol and leptin levels are significantly altered.
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 female rats undergoing endurance exercise and reduced calorie intake, eating a diet high in cholesterol does not change progesterone levels in the blood, but it does change estradiol and leptin levels.
See the scientific wording
In female rats undergoing 12 weeks of treadmill endurance training with energy restriction, a high-cholesterol diet does not significantly alter serum progesterone levels compared to a low-cholesterol diet, despite significant changes in estradiol and leptin, suggesting differential hormonal sensitivity to dietary cholesterol.
When female rats train hard and eat less, their fat cells make less leptin, which allows more of a hormone called estradiol to be made from cholesterol. Progesterone levels stay the same because its production does not depend on the same cholesterol pathway under these conditions.
What the research says
1 studyWhen female rats exercise and eat less, giving them more cholesterol makes one hormone (estradiol) go up but doesn’t change another (progesterone), showing they react differently to cholesterol.
