Metabolism describes the many chemical reactions that take place in the body and play a role in our overall health. Although the word is often used in the context of calorie burning, metabolism also controls factors such as body temperature, energy levels and the digestive system. It is therefore crucial that your metabolism is well regulated.
Symptoms of an accelerated metabolism include a feeling of restlessness, heat, difficulty concentrating, a tendency for softer stools and potential weight loss. On the other hand, symptoms of a slowed metabolism can include feeling cold, tiredness, fatigue and changes in the condition of your skin, hair and nails.
