The Claim
In female C57BL/6J mice, continuous access to a high-caloric diet in addition to standard chow induces leptin resistance within two weeks and causes significant increases in body mass, demonstrating that dietary pattern directly influences hormonal regulation of energy balance.
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.
Female C57BL/6J mice fed a high-calorie diet alongside regular food develop leptin resistance and gain weight within two weeks, showing that diet directly alters hormonal control of energy balance.
See the scientific wording
In female C57BL/6J mice, continuous access to a high-caloric diet in addition to standard chow induces leptin resistance within two weeks, accompanied by significant increases in body mass, demonstrating that dietary pattern directly influences hormonal regulation of energy balance in a diet-induced obesity-prone strain.
Eating a high-calorie diet causes fat tissue to grow and release more leptin, but the brain stops responding to this signal. Without leptin's control, hunger signals in the brain stay active, so the animal keeps eating and stores more fat, leading to rapid weight gain.
What the research says
1 studyStudy: Effects of periodic intake of a high-caloric diet on body mass and leptin resistance.
When mice that are prone to obesity are given junk food along with their normal food, their bodies stop responding to a hormone called leptin that normally tells them to stop eating — and they quickly gain weight. This happened within two weeks, just like the claim said.
