The human body can be compared to an engine, which works on the principle of burning fuel and producing energy. Same is the case with our bodies, which need fuel to perform the various metabolic reactions. The food we consume everyday provides energy in the form of calories for all these reactions. The rate of these metabolic reactions and amoun6ts of calories consumed depends upon the rate at which a human body performs various physical activities. Thus the calorie needs of each individual are different and depend upon his or her lifestyle.
Calories are a way to measure energy and are an important factor for controlling the body weight. Intake of less than required amounts of calories lead to weight loss whereas intake of more than the required amounts of calories leads to a gain in body weight.
Significance of calories
Most food nutrition charts mention the calorie content of every food it suggests people to consume. The food nutrition chart mentions the intake of food in every meal according to its calorific value and the amount of physical activities generally performed by most people at different times of the day. For e.g. according to the food nutrition chart the calorie intake of all people irrespective of their age should be highest in the morning. This is because most people begin their daily chores and ought to be physically active at this time of the day. So according to the food nutrition chart, breakfast is the most calorific foods, which are capable of providing energy for these activities. Another important thing to be known is that most people try to skip meals particularly their breakfast. This is extremely harmful to the health and should be certainly avoided.
Lunch is another important meal of the day. According to the chart consume pulses, vegetables and fruits at this time of the day. Last but not the least is the dinner. Dinner time is time when you have finished all your physical activities and you are just about to sleep. Sleeping is an activity in which you consume the least amount of calories. So, keep your dinners as light as possible. Intake of raw vegetables in form of salads is the best way to keep your calorie intake low. So make sure you include a plate of salad in your diet. Another important thing to remember is that finish your dinner two hours before you sleep. This will help to metabolize the consumed food well before you sleep.
