This is true because athletes’ bodies demand a lot of energy and body-building foods than people of sedentary lifestyles. During one hour of hard training an athlete may expend 30% of his or her total 24-hour energy output, therefore they require foods high in carbohydrates. They also need to replace certain elements in their body through diets such as potassium, and magnesium that are lost in significant amounts in the sweat. Athletes also need foods high in protein. Proteins are degraded and amino acids are oxidized during physical exercise. Proteins are also retained during muscle building training hence athletes have bigger muscles.
The requirement of nutrition is different in a sedentary and athletic lifestyle. This is because athletes perform more vigorous exercises and require a high amount of energy. People who are indulged in a sedentary lifestyle have very less physical activity and require fewer amounts of protein and carbs in their diet.
Further Explanation:
To stay fit, an individual is required to eathealthily and indulge in the daily routine of exercise. A healthy diet mainly helps in providing the energy to perform physical activity without getting tired. Iron, vitamins, protein, fluid, carbohydrate, and minerals should be included in the diet to maintain energy in the body.
An athlete needs a high amount of carbs to store energy in the form of glycogen. They also require enough amounts of proteins to maintain muscles. Also, add unsaturated fat in their diet and drink a lot of water to avoid dehydration. On the other hand, in sedentary life requirement of nutrition is different because they indulge in very less physical activity. They mainly involved in activities such as watching TV, reading books and playing video games by lying down and sitting. It is not referred to as a healthy lifestyle because it develops many health issues.

Companies can refuse to pay women workers who are new to the company the same wage as male workers who have been there for a number of years.
Explanation;
The gender pay gap or gender wage gap is the average difference between the remuneration for men and women who are working. Women are generally paid less than men. There are two distinct numbers regarding the pay gap: unadjusted versus adjusted pay gap.
The gender pay gap can be a problem from a public policy perspective even when the reason for the gap is entirely voluntary, because it reduces economic output and means that women are more likely to be dependent upon welfare payments, especially in old age.
