Around 100 genes linked to fat storage have been identified and published in the Nature journal, by a team including Swedish scientists.
But a connection does not mean the genes “cause” people to become overweight. Genetics often provides an altered context, which interacts with people’s circumstances to create a tendency towards certain outcomes.
Certain genes linked to appetite and habit forming seem to be closely connected to BMI.
This study is a far expanded version of a DNA test from 2010.
