Spending a full day in very hot or very cold rooms doesn’t make people eat more or less food overall, even though their bodies react to the temperature.
Scientific Claim
Twenty-four-hour passive heat exposure at 32°C and cold exposure at 16°C do not significantly alter total daily energy intake in healthy, young, active men compared to a thermoneutral condition at 24°C, despite inducing measurable physiological and behavioral changes.
Original Statement
“Contrary to the literature, total EI was not modified by cold or heat exposure (P = 0·120).”

Assessment Explanation
The study is a well-controlled RCT with randomization and direct measurement of energy intake. The null result is statistically reported and appropriately stated without overinterpretation.
Evidence from Studies
Supporting (1)
Twenty four-hour passive heat and cold exposures did not modify energy intake and appetite but strongly modify food reward
Even though being too hot or too cold made people want different kinds of food, they still ate about the same amount overall—so their total calories didn’t change.
