You use energy no matter what you’re doing, even when sleeping. That is called Basal Metabolic Rate.
Metabolism comprises the processes that the body needs to function. Basal metabolic rate is the amount of energy per unit time that a person needs to keep the body functioning at rest. Some of those processes are breathing, blood circulation, controlling body temperature, cell growth, brain and nerve function, and contraction of muscles. Basal metabolic rate (BMR) affects the rate that a person burns calories and ultimately whether that individual maintains, gains, or loses weight. The basal metabolic rate accounts for about 60 to 75% of the daily calorie expenditure by individuals. (wikipedia)
And we can improve our BMR!!!
2 lbs (1 kg) of muscles needs 28 kcals for their maintenance, and same amount of fat needs 7 times less then that.
So if we make our body composition more muscular we can slightly improve our energy expenditure while we are resting.
And that we can accomplish with strength training and good nutrition.
