The Science Behind Weight Loss- Know More!

Hello All!!!

Everyone talks about weight loss but what about the science behind it? You want to know the process of weight loss? So let me explain the basics. In a nutshell, weight loss happens when you burn more calories than you consume. Hop on to find more.


how many calories

People talk about counting calories for weight loss but have you ever wondered what they are? Calorie is a unit that measures energy derived from what we consume. The human body requires this energy to work properly. When there is an excess of energy or calories, the body stores it for later use. The stored calories are converted into fat.


Metabolism is defined as follows:

It is a process by which your body converts what you eat and drink into energy. During this complex biochemical process, calories in food and beverages are combined with oxygen to release the energy your body needs to function.

The number of calories needed by your body to perform the basic functions is called the Basal Metabolic Rate (BMR) or metabolism. Many people blame their slow metabolism for their weight gain. The fitness world is always in search of ways to boost metabolism! Coming back to from where we started, when you burn all the calories consumed you don’t give the body a chance to store it. Thus, reduces the chances of piling on kilos.

Determining the Basal Metabolic Rate

You must be wondering what determines basal metabolic rate. An individual’s BMR depends upon several factors like height, size of the body, body composition, gender and age. You can determine your BMR by multiplying your weight in pounds with 10. There are two other factors that contribute to your calorie need and they are food processing and physical activity.

how to lose weight

In order to lose weight one has to reverse the energy balance. One has to use more energy than consumed and create an energy deficit. An energy deficit can be created by reducing the intake of calories and increasing the physical activity. Most females need around 1200 to 1500 calories a day to do the basic tasks. So, your diet should be such that it provides you with at least these many calories. Here nutritionists do the trick, they recommend a diet plan that limits the intake of calories without compromising on the nutrients so that the body remains healthy. You should also work out every day. When you consume fewer calories than you use, your workout will burn the calories stored as fat in the body.

Factors that adversely affect weight loss

The above explanation may seem logical to you but there are certain factors that hamper the loss of weight and they are as follows:

Eating less

People usually ignore this. When you don’t consume sufficient calories your body begins fretting. So, whenever you eat food, the body starts storing it as fat thinking that you may not give it any food in the future! The same happens when there is a long gap between meals or when you are taking meals infrequently.

Way out: The way out is to eat smaller meals more frequently during the day. Most health experts recommend 6 small meals a day.


Lack of rest and stress affect the body’s energy consumption. You need proper relaxation and sleep. When you overuse your body, you are not giving it time to repair itself.

Way out: The way out is to start meditating and finding inner peace. You also need 8 hours of sound sleep to feel fresh and rejuvenated.

Hormonal imbalance

Hormonal imbalance can hamper your weight loss goals. Most women gain kilos when they are growing up or during menopause.

Way out: The way out is visiting the doctor asap!

Though there are genetic factors too that affect weight gain and weight loss in individuals, we are not getting into that! Otherwise, you can lose weight by exercising regularly, eating right and sleeping properly.

Hope this post has been helpful in clearing up your doubts!
