Eat Regularly for Correct Body weight

The causes of obesity are complex and not fully understood. A number of factors have been investigated and there is a great deal of evidence to suggest that dissociation from normal eating patterns and food intake are a significant contributor … Continue reading

Does Drinking Water Increase Metabolic Rate?

Water is an essential component of human health, and studies suggest that water consumption, in its pure form, is decreasing as other beverages become cheaper and more widely available. Water is required by cells in order to maintain the aqueous … 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

The Thermogenic Effects of Green Tea

Tea is a decoction of the Camellia sinensis leaf. Tea comes in a number of different forms including green tea, oolong tea and black tea, with the degree of fermentation during processing determining the final product. Fermentation can alter the … Continue reading

More on Dietary Thermogenesis

The thermic effect of food and the thermic effect of exercise are often overlooked when energy balance is considered. Obesity is considered by many to be a simple balance between energy consumed and energy expended, but this does not take … Continue reading

Calorie Counting: More Holes

Calorie counting relies on the energy balance equation to explain body weight changes. Proponents of calorie counting claim that the change in body weight experienced by an individual is related solely to the amount of physical activity they perform, in … Continue reading

Resting Metabolic Rate Increases With Body Weight

The resting metabolic rate (RMR) is the energy expended by the body at rest with the individual sitting or lying. In other words it is the energy required for normal metabolic and homeostatic regulation. The basal metabolic rate is similar … Continue reading

Smoking and Body Weight

Both smoking and obesity increase the risk of mortality. However, smoking is inversely related to body weight. This suggests that something about the act of smoking, or its associated behaviour may prevent weight gain. While smoking is bad for the … Continue reading

Thermic Effect of Food: Glucose Versus Fructose

The thermic effect of food (TEF) is defined as the energy used in the digestion, absorption, transport, metabolism and storage of macronutrients following a meal. This energy can be measured as a rise in body temperature. The thermic effect of … Continue reading
