The thermic effect of food is a reference to the increase in metabolic rate (the rate at which your body burns calories) that occurs after ingestion of food. When you eat food, your body must expend some energy (calories) to digest, absorb, and store the nutrients in the food you've eaten. Therefore, as a result of the thermic effect of food, by consuming calories you actually increase the rate at which your body burns calories.
A calorie is defined as the amount of heat energy needed to raise the temperature of one gram of water by 1°C (1.8°F).
Researchers from the University of Rochester's Center for RNA Biology have identified a new way to potentially slow the fast-growing cells that characterize all types of cancer. The findings, reported in the journal Science, are a long way from being applied in people but they could be the basis of a treatment option in the future.
