The Claim
Fasting plasma leptin concentrations decrease significantly during short-term alternate-day fasting and continuous energy restriction compared to an energy-balanced diet in middle-aged overweight men, while fasting glucose and insulin levels remain unchanged.
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 middle-aged overweight men, fasting leptin levels drop during short-term alternate-day fasting and continuous calorie restriction compared to a balanced diet, but fasting glucose and insulin levels do not change.
See the scientific wording
Fasting plasma leptin concentrations decrease significantly during short-term alternate-day fasting and continuous energy restriction compared to an energy-balanced diet in middle-aged overweight men, while fasting glucose and insulin levels remain unchanged.
When the body stores less fat due to eating fewer calories, fat cells send out less of a hormone called leptin. This happens even when blood sugar and insulin levels stay the same because the body is not using glucose or insulin differently — only the fat cells are signaling less because they have less fuel inside them.
What the research says
1 studyIn overweight middle-aged men, both intermittent fasting and daily calorie cutting lowered a fat-regulating hormone called leptin, but didn’t change blood sugar or insulin levels over 10 days — just like the claim says.
