One of the top New Year resolutions every January is to lose weight. While people may leave behind a number of things on their journey from one year to another, what they do carry forward, are those extra kilos.
In a content published in CNN, Alexxai Kravitz, a researcher at the National Institute of Diabetes and Digestive and Kidney Diseases, marked out that there are three major components to energy expenditure.
They consist of the basal metabolic rate, diet-induced thermogenesis (breaking down food) and physical activity.
As per to Kravitz, for most people, basal metabolic rate records for 60 percent to 80 percent of full energy expenditure.
About 10 percent of the calories are burned while digesting the food one eats, which means approximately 10 percent to 30 percent are lost by physical activity.
Kravitz said, “An important distinction here is that this number includes all physical activity: walking around, typing, fidgeting and formal exercise.” He added, “So if the total energy expenditure from physical activity is 10% to 30%, exercise is a subset of that number.”
Further added, “The average person — professional athletes excluded — burns 5% to 15% of their daily calories through exercise,” he said. “It’s nothing, but it’s not nearly equal to food intake, which accounts for 100% of the energy intake of the body.”
As per to calculation carried out by Harvard Medical School, one could quickly undo the calories burnt in 30 minutes of running could be effectively canceled out with just a piece of cake or mixed drinks.
The completion by the author is that if one has to lose weight, it is better off not exercise out and just simply eating less.
