A Complete Guide To Understand Your Metabolism

What is metabolism? Metabolism is the term used to describe all the chemical reactions happening in our body, that keeps us alive. Metabolism can be broadly classified into two categories: Catabolism and Anabolism. Catabolism breaks larger molecules into simpler ones, whereas anabolism does the opposite i.e it builds complex molecules from simpler ones. These processes require energy thus, metabolism is the rate at which our body burns calories. 

Total Daily Energy Expenditure (TDEE) is the number of calories our body burns in a day with exercise included. TDEE comprises of the following:

  • Basal metabolic rate
  • The thermogenic effect of food 
  • Exercise activity thermogenesis
  • Non-exercise activity thermogenesis

BASAL METABOLIC RATE  

We require energy even at rest. The basic functioning of the body like breathing, circulating blood, cell production requires energy. The amount of energy expended by the body to function at rest is called the basal metabolic rate (BMR). BMR varies largely amongst people belonging to different genders, health condition, age groups, heights, and weights.

THERMOGENIC EFFECT OF FOOD (TEF) 

Though we don’t realize, activities like chewing, digestion and absorption of nutrients, uses energy too. This is known as the Thermogenic Effect of Food. The higher the energy content the food has, the higher the TEF.

EXERCISE ACTIVITY THERMOGENESIS

These are calories our body burns via exercise we do intentionally. It’s a well-established fact that exercise burns more calories. Doing any form of exercise, be it Zumba, cycling, or running not only help in weight reduction, but it also helps in maintaining weight too.

NON-EXERCISE ACTIVITY THERMOGENESIS

It’s the energy that’s expended by our body to go about our daily lives, apart from sleeping, eating, and exercising. It involves activities like walking, climbing stairs, cleaning, etc. Incorporating activity into daily life can be an easy way to burn some more calories. These include activities such as, getting off a stop earlier on the bus or doing the dishes by hand rather than the dishwasher or gardening.

These 4 components (BMR+TEF+EAT+NEAT) together make up our Total Daily Energy Expenditure (TDEE). Our TDEE compared to what we eat determines whether calories in equals to calories out making our weight stay the same, increase or reduce. You may not be able to control your BMR or TEF but you can control your EAT, NEAT and of course, the calories you consume too.

 You can monitor how many calories you intake and burn through walking in the smart health and fitness app “Health Click Away”. Additionally, “Health Click Away” gives you an insight into how much of the individual macronutrients you have consumed per day. Tracking food has never this easy!! 

Let’s channel our focus on the things that we can take control and reach our health goals.
