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.
