There would not have been a single day in your life from adulthood that has passed without thinking about food. Yet how many of us have thought sensibly about food and given the reasonable attention it deserves? This in itself is quite fascinating, considering the fact that we cannot survive without food. Either way, you deserve a pat on the shoulder, as you have decided to put on some weight. To get a better understanding of the chemistry of weight gain, let’s take a look at the fine details related to calories, energy, body mass index, and similar parameters.

The energy that a given food can release during metabolism is measured in calories per gram.

One calorie (cal) is defined as the amount of heat required to raise the temperature of 1 kg of water to 1 degree Celsius. Nutritionists measure the energy content of food in kilocalories (1 kcal = 1000 cal) and calories. Typically, an adult requires 1200-1800 calories a day to maintain basic life processes, and an additional 50-150% of this amount to meet the energy needs of physical activities. In other words, the calories consumed also differ according to the activities.

A person who sleeps spends 50 to 75 cal / h. A person who does other activities such as swimming, playing basketball or shoveling can consume ten times more, or even more. One pound (0.45 kg) of body fat is roughly equivalent to 3,500 calories of stored dietary energy. Calorie consumption increases in direct proportion to body weight. Your body gains or loses weight depending on a simple formula. If you consume more energy through food than your body actually burns, you are likely to gain body weight. Therefore, this main rule ensures that you should consume more calories than you expend in work, exercise, and bodily activities.

I would like to say from my experience that there is a Basic Principle of Nutrition that is universally true. In its simplest form, the basic Health equation can be written as Health = Nutrition + Calories. There is no shortage of information on health and nutrition. In fact, it is this abundance of literature that often perplexes one as to how healthy people could make good nutrition, and how much deviation from ideal nutrition we could afford.
Remember, KNOWLEDGE is essential during the weight gain process.
