When people drink less water, their bodies seem to switch to burning more fat and eating less food, and they burn fewer calories overall. A hormone linked to water balance also affects fat burning.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

The combined effect of consuming whole foods and hydrating in a fasted state increases daily energy expenditure by 100–150 kcal compared to consuming ultraprocessed foods and not hydrating in a fasted state.
When people drink less water, their bodies tend to burn more fat and less sugar for energy, even if they’re not trying to lose weight.
People who drink less water tend to eat less food later, even if they’re not hungry or trying to diet.
People who don’t drink much water may burn slightly fewer calories over the course of a day, especially in populations living in hot, dry climates.
