Does the month you are born in have anything to do with BMI?

  • A new study reveals that people conceived in colder months tend to have a lower body mass index (BMI) and less internal fat than those conceived in warmer months.
  • The research, published in Nature Metabolism, suggests that weather conditions during conception may influence a person's physiology throughout their life.
  • Brown adipose tissue, which generates heat, is more active in individuals conceived during colder seasons, leading to higher energy expenditure and lower fat storage.
  • This association between conception season and brown adipose tissue activity is primarily attributed to lower outdoor temperatures and greater daily temperature fluctuations during the fertilization period.
  • Further research with diverse populations is needed to explore the underlying mechanisms and the influence of diet and other environmental factors.
