serg [7]3 years ago

Answer:

Exercise

Explanation:

Cognitive impairment is the condition where a person has difficulty in recalling or remembering things. They also find it difficult to perform daily tasks and make decisions. They are not able to concentrate hence also have trouble learning new things. Cognitive impairment can be present genetically although it is observed almost in a large number of ageing people.

Exercise has been proven to help in cases of mild to severe cognitive impairment. In an experiment it was proven that 6 months of aerobic exercise reversed cognitive impairment symptoms in ageing people. It particularly benefits people carrying the APOE4 gene variant responsible for making people susceptible to Alzheimer's.

In addition to loss of muscle mass, which is a symptom of inadequate calorie intake?
astraxan [27]

In addition to loss of muscle mass, inadequate calorie intake can lead to loss of bone density and an increased risk of fatigue, illness, injuries and poor recovery.

<h3>Why is it important to consume adequate calories?</h3>
  • When your consumption of calories is not adequate, your body will not get all the necessary nutrients.
  • It slows down the metabolism so as to conserve energy
  • Calorie restriction can lead to reduce in leptin, a hormone that regulates appetite.
  • Lower levels of leptin can lead to increase in hunger thus a person overeats. This results in increase in body weight.
  • Low-calorie dieting increases stress and results in the release of the stress hormone (cortisol).
  • Due to response to stress, the body conserves energy and the metabolism slows to combat the risk of starvation.
  • Therefore, it is important to consume appropriate amount of calories and nutrients.
