Seasonal changes in 24-h and basal energy expenditures in rural Gambian men as measured in a respiration chamber.

Adaptation of 24-h energy expenditure (24-h EE) to seasonal variations in food availability was studied, by using a respiration chamber, in 18 rural Gambian men on three occasions: period 1 ― at the end of the rainy season, which is characterized by low food availability: period 2 ― during the nutritionally favorable dry season: and period 3 ― at the onset of the following rainy season.
