Diet and Exercise

  • A healthy diest has the right balance of food types.
  • Carbohydrates, fats and proteins are used by the body to realease energy and build cells.
  • Mineral ions and vitamins are needed for the body to keep healthy.
  • If the diet is unbalanced, a person will become malnourished.
  • If you exercise, the body uses more energy. Exercise increases the metabolic rate, so chemical reactions in cells work faster.
  • The proportion of body fat and inherited factors can also affect the metabolic rate.

Weight Problems

  • It is important to get the energy balance correct for good health.
  • If the energy you take in equals the energy that you use then your mass will stay the same. Eating too much can often lead to becoming overweight or obese.
  • Long-term obesity can lead to othe health issues such as type 2 diabetes (high blood sugar).
  • This kind of problem can be reduced by eating less carbohydrates and doing more exercise.
  • It is also possible to become unhealthy by eating too little food. It may become hard to walk and people who eat too little may suffer from deficiency disease due to a lack of vitamins or minerals.
