What is an example of pseudo science?

Pseudo (false) science is a term used when scientific terms and expressions are used to confuse unsuspecting "marks" to buy or use a product or service. This is a process used since the middle ages when imposing Words from the religious ceremonies such as hoc est enim corpus became hocus-pocus to convince the ignorant that real magi was going on.Examples today would include:

• most popular diet plans which melt off fat
  
• palm reading an Astrology
  
• creationism
  
• non-traditional medical methods relying on herbs, auras, mystic vibrations and psychic powers
