Introduction: Our sedentary lifestyles have made us prone to obesity and other lifestyle induced diseases. To add salt to the injury, we tend to grab anything which is available. This is because of our fast paced lives we are left with little time to prepare healthy food and eat it leisurely. Thus, we tend to eat fast foods or junk foods such as burgers, pizzas and hot dogs etc. These food items are fried in oil having high cholesterol content and we add calorie rich items like bacon and meat to them, forming a dangerous combination.

Our body requires a certain amount of calories in order to maintain the various body processes, physical movement and the activities that we may indulge in throughout the day. Every individual performs different set of activities every day and needs different amount of calories. For example some one who has to perform physical labor would need to consume a larger number of calories than someone who travels with the help of a vehicle and has to do computer based work which requires long sitting hours.
