Aspects of Nutrition and Weight

People’s body weight is affected by both genetic and environmental factors. Scientists now know of 14 genes that increase the risk of gaining weight (University of Virginia Health System, 2021). In addition, family history may be a factor potentially affecting people’s weight. Children and grandchildren of obese people are more likely to suffer from uncontrolled weight gain. At the same time, excessive thinness can also be explained by genetics. Environmental factors that influence weight include where a person lives and works, eating habits, and country of residence (Australian Government Department of Health, 2021). Living in a metropolis can change one’s eating habits — it is cheaper and quicker to buy fast food than to prepare healthy meals at home. In addition, stress is a significant factor in weight gain. This is due to the production of cortisol, which keeps the body on high alert for trouble and requires storing as much energy as possible.

Among the factors that affect personnel productivity, the most significant influence is nutrition. If workers cannot eat properly, their efficiency is low, and the company suffers losses because of it. When people work hard, they need the extra energy support provided by fats, carbohydrates, and protein. Among carbohydrates, one of the most important is glucose — it affects brain nutrition and energy supply to other cells in the body. Protein speeds recovery suppresses appetite and provides amino acids, which the body uses as an energy source. Fats are an essential part of every diet; they positively affect circulatory system function, support the immune system, and improve thought processes. Following the principles of a healthy diet, as well as regular moderate exercise, can have a positive effect on a person’s performance.
