Exercising is a great way to be healthy and maintain your weight. It makes our body flexible, improves our metabolism and also helps with stress and depression. Many people suggests exercising for weight loss, but the question is if it is really an essential to loose weight?
We have been conditioned to believe that exercise is an essential ingredient to loose weight but according to science, it might not be that important of a factor to loose some pounds. A very uncommon fact about exercising is that it amounts to a very small calorie expenditure of your daily life. Obesity researcher Alexxai Kravitz suggests that there are three main components of calorie expenditure : 1) basal metabolic rate, or the energy used for basic functioning when the body is at rest; 2) the energy used to break down food; and 3) the energy used in physical activity.
According to Kravitz, basal metabolic rate amounts to about 70% of energy expenditure and we have no control over the same. Energy spent in digesting food amounts to about 10%. All of this included, it leaves only about 20% room for physical exercise along with daily activities like walking, carrying weight,etc. What I am trying to imply is that food we consume actually amounts to 100% of calories/energy that goes inside our body while exercising only amount to about 10-30% of expenditure. This basically shows that erasing all the fat on your tummy is not as dependable on exercise as your gym membership shows.
It is difficult to create a calorie-deficit only through exercising. To explain it in easier words, “If a hypothetical 90-kg man added 60 minutes of medium-intensity running four days per week while keeping his calorie intake the same, and he did this for 30 days, he’d lose 3 kgs.” And to compensate the exercise, if the man adds food and rest in his daily routine his weight loss will be even less significant. So for an overweight person to loose weight solely by exercise, it will take him a lot of time to reach his goal.
Studies say that generally people who exercise may consume more than on a daily basis believing they lost a lot of calories or simply because they were hungrier. “You work hard on that machine for an hour, and that work can be erased with five minutes of eating afterward,” Hall explained. It is suggested that reducing calorie intake and replacing high calorie food with low calorie ones are more helpful on your way to effective weight loss. Exercising boosts weight loss in other subtle ways but depending wholly on it may not be the best idea. We need to change the way we look at exercising, it is immensely helpful for preventing diseases and living a healthier life but it may not be the best way to lose weight. Also, it has been said many times that exercise helps in building muscles, more than losing weight. In order to lose weight there should be a balance of physical activity and calorie intake.
