The Claim
A 15-day very low-calorie diet in obese women results in a reduction in resting metabolic rate that is statistically significant and greater than the reduction expected from weight loss alone, indicating a physiological adaptation to energy restriction.
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.
After 15 days of a very low-calorie diet, obese women experience a drop in resting metabolic rate that is larger than what would be predicted by the amount of weight lost, showing a measurable physiological adjustment to reduced energy intake.
See the scientific wording
The reduction in resting metabolic rate following a 15-day very low-calorie diet in obese women is statistically significant and exceeds what would be expected from weight loss alone, suggesting a physiological adaptation to energy restriction.
When calorie intake drops sharply, the body reduces the amount of active thyroid hormone in the blood, which slows down the energy-burning activity of cells in organs like the liver and muscles, causing the body to burn fewer calories at rest.
What the research says
1 studyStudy: Resting Metabolic Rate, Body Composition and Thyroid Hormones
After eating very few calories for two weeks, the women’s bodies burned fewer calories at rest than expected just from losing weight — meaning their bodies slowed down on purpose to save energy.
