Diet and exersize

  • A balanced diet includes everything needed to keep the body healthy.
  • Different people need different amounts of energy, because the metabolic rate varies between people
  • Metabolic rate: The rate at which reactions take place in your body.
  • If energy taken in < the energy used, the person will lose mass.
  • The more exersize you do, the more food you need
  • If the diet is unbalanced, the person can become malnourished
