Metabolism                     Home       Ask your question about weight loss

Metabolism is the rate at which the human body uses energy to support all basic function required to sustain life like breathing, and additional activities like exercise and also for digestive activities. It consists of 3 parts - the basal metabolism or resting metabolism, the thermal effect of food and physical activities.

The basal metabolic rate (BMR) is the reason why some people remain thin despite even if they do not exercise. The basal metabolic rate depends on a number of factors and can be increased. More information on basal metabolic rate and how to increase it

The thermal effect of food is the energy used by the body parts like the stomach and intestine to absorb nutrients from the food we eat. This accounts for approximate 10% of the total metabolism. When on diet, the food intake is less, so energy consumed by this process reduces.

Physical activities include exercise, housework and recreational activities. Increasing physical activities and controlling your diet, is the safest way to lose weight. Approximate Calories consumption per minute for  some common activities are specified in the table below:
