Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that a person can lose weight by being exposed to cold temperatures?

Yes. Scientific literature confirms that exposure to cold temperatures stimulates non-shivering thermogenesis and activates brown and beige adipose tissue, which increases energy expenditure.

Verdict: SUPPORTED · 8 sources for, 0 against · Last checked

The analysis

The retrieved papers consistently report that cold exposure activates brown and beige adipose tissue, leading to non-shivering thermogenesis and increased energy expenditure. While some papers caution that the quantitative impact on actual weight loss in humans may be small or difficult to sustain as a standalone obesity treatment, none of the sources refute the core physiological mechanism that cold exposure increases energy expenditure through thermogenesis. Therefore, the claim is supported.
