1.2 Weight Problems

• If you take in more energy than you use = excess stored as fat.
• If you take in less energy than you use = decrease of BMI  

• Eating a too much food = overweight or obese.
• Eating too little food = underweight or anorexic
• (Both forms of malnourishment.)

Problems

Obesity can lead to serious health problems:

• Arthritis
• Type 2 diabetes (High blood sugar levels which are hard to control)
• High blood pressure
• Heart disease 
• Obese people are more likely to die young. 

Anorexia can lead to health problems:

• Menstrual cycle stopping
• Tiredness
• Weak bones
• Deficiency disease           

Losing Weight

• Reduce amount of energy you have, by cutting back the amount of food you eat. (Cut down on energy rich foods)
• Increase the amount of energy you use, by doing more exercise.
• The best is to do both - reduce your energy intake and exercise more. 

 You need some body fat to cushion your internal organs.
