I know that this will be an unpopular post, but…
When body temperatures are low, we burn more fuel to stay warm. When we’re hot, we tend to eat less. Our climate-controlled lives today may be one reason we’re gaining weight.
Climate control is cited as one of “Ten Putative Contributors to the Obesity Epidemic.”
Between 1970 and 2000, the average internal home temperature in the United Kingdom has increased from 13◦ C (55 Fahrenheit) to 18◦ C (64 Fahrenheit) (EHCS, 2000). Perceptions of thermal comfort in the United States have also increased, with the thermal standard for winter comfort increasing from 18◦ C (64 Fahrenheit) in 1923 to 24.6◦ C in 1986 (76 Fahrenheit) (Space Heating Technology Atlas 2004).
Rather than raising the thermostat so much, wear a sweater indoors this winter. Save some fuel $$ and burn a few more calories!
