Diet and Exercise

Diet and Execise:

  • Regular exercise and a balanced diet are needed to keep the body healthy. 
  • Too little food leads to a person being underweight and prone to certain types of illness, while too much food and not enough exercise leads to a person being overweight and other types of ill health.

A mixture of different types of food in the correct amounts is needed to maintain health.

The main food groups are carbohydratesfats and proteins.

Keeping Healthy

Diet and Exercise:

  • Regular exercise and a balanced diet are needed to keep the body healthy. Too little food leads to a person being underweight and prone to certain types of illness, while too much food and not enough exercise leads to a person being overweight and other types of ill health. 
  • The main food groups are: carbohydrates;  a source of energy for life processes (potatoes, pasta, bread bananas) fats; makes cell membranes and insulates the body and proteins; for growth and repair-building cells (meat, fish, eggs and cheese).
  • If someone’s diet consists of food with a lower energy content than the amount of energy their body uses, the person will lose body mass.
  • Respiration is a chemical reaction that allows cells to release energy from food. The metabolic rate is the speed at which such chemical reactions take place in the body and varies because of several factors, including age, gender and inherited factors.Metabolic rate is also affected by the: proportion of muscle to fat in the body and the amount of exercise and other physical activity.The metabolic rate increases as we exercise and stays high for a while afterwards. People who exercise regularly are usually healthier than people who don't.
