  • 7. GENETICS
    • Genes controlling appetite and metabolism effect chances
    • Studies with identical twins have shown 77% childhood obesity is inherited
    • FTO gene study concluded that heterozygous 30% and homozygous 70% chances of increased risk of obesity
    • More genes being discovered that increase obesity chances
    • “ thrifty genotype hypothesis”
    • -same genes that helped our ancestors survive famines are challenged by food being plentiful year round.
  • 8.
    • 50 chromosomal locations are relevant to obesity
    • Genetic factors play a role but to fully develop a lot of caloric intake must occur
