How we burn calories

How we burn calories
We always wonder how we increase weight even with a bite of a cheese burger and your friend finished a big chicken pizza and didn't gain even a gram of weight. Well, the answer belongs to our metabolism.
Metabolism means your body's conversion of what you consume and drink into either energy or stored fat. Our metabolism alters as we grow older, studies reveal that after 30 it tends to decelerate which makes weight loss a difficult task then.
But the good news is we can still effort to boost our metabolism at whatever age we're at!
How do we burn calories?
Each ones calorie demand for weight maintenance differs from the other. Metabolism rides on three factors, these are really the ones we can change and play with to rise our metabolism.
Resting metabolic rate
We are burning calories even when we are going in a bus, watching TV, sitting in front of the computer and still while sleeping; the reason is that our body demands energy to carry out these functions. The number of calories the body utilizes while resting is called resting metabolic rate, which accounts to 65-75 % of calories we use daily.
It is seen that men burn off more calories than women, weighty or fat people burn more calories than slimmer ones - even though they remain heavier, and younger people burn more calories than oldies. Our body's resting metabolic rate descents by 10% after the age of 30. The reason behind this is as we age more muscle is replaced with fat, which directs to age - related decline.
Physical activity
Our body in motion burns some 15 to 30 % of your daily calories. This physical action can be in the form of exercise like running, in the gym, skipping, they can also be general regular activities like cooking, walking upstairs, fighting with your siblings or even fidgeting in a crowded train.
Processing of food
At last the rest of the 5 to 10 % of our calories is burned while digesting, absorbing, transporting and storing what we eat. The energy needed for this process is referred to as the thermic effect of food.
