All our body has been compared to a machine and how it works. So, one of the basic underlying principles applied here is ‘that energy can be neither created nor destroyed, it can only be converted’. With this in mind, we have to see how this can be applied to food intake, physical activity and body stores of fat or breakdown of body fat.
Energy conversion thermodynamics
* Food –> Physical activity –> Energy output
* Food –> No physical activity –> Body fat deposit
* Body fat –> Only physical activity –> Energy output and reduction of body fat
In terms of food:
* One masala dosa –> One hour of walking at 3mph. –> 200 Kcals utilised
* One masala dosa –> No physical activity –> 200 Kcals deposited as one ounce of body fat
* One ounce of body fat –> only physical activity –> 200 Kcals out put and fat reduction
How does your eating excess of different foods convert to body fat
It is generally believed that 3500 Kcals from food, in excess of our energy necessities, converts to 1lb. of body fat deposits. You will be interested to see how different foods contribute to this. In an attempt to increase our awareness of association among physical activity and energy intake, and to discourage overeating, just have a look at the table which presents the body weight-gain equivalents of selected foods. For example, it shows that one 200ml. bottle of cola beverage taken in surplus of daily requirements of energy, causes a weight gain of 1lb. (500g) in 33 days. Just one piece of mysore pak further per day will help you to weigh 1lb. more in 10 days flat!
However, body weight gain and its composition look on factors such as gender, age, physical activity, diet and initial weight. Hence, these figures are average and do not represent actual or closing values. Nevertheless, weight gain equivalent tables will be useful in increasing our awareness of the weight that can be gained by eating comparatively small portions of food above our daily requirements. So, young folks, while I do not want to divest you of the fun of eating, in your youth, it will be good to identify for yourselves, how your ‘time pass’ canteen hours can extra to your future weight!!
