What Foods Can Keep You Warm?

Food has a significant effect on body temperature. This is evident during a period of fasting when body temperature can drop substantially. This is because during periods of food deprivation, the body will reduce its oxidation of food to preserve … Continue reading

The Thermic Effect of Food

The thermic effects of food refers to the heat produced when food is oxidised. This heat effect can be significant and is a contributor to the overall metabolic rate. When food is eaten it is digested and the component parts … Continue reading

Does Palatable Food Stimulate Thermogenesis?

Thermogenesis is the generation of heat from food energy. One particular type of thermogenesis is diet induced thermogenesis (DIT). Diet induced thermogenesis, sometimes referred to as the thermic effect of food (TEF), is the generation of heat directly as a … Continue reading

Circadian Variations in Thermogenesis

Consumption of food results in a significant increase in metabolic activity. This activity relates the energy required to absorb, metabolise, store and excrete food components. Such thermogenesis is called the thermic effects of food (TEF), and it can contribute significantly … Continue reading
