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.
