The time of year when a person is conceived may affect their likelihood of developing obesity later in life, according to Popular Science.
Research shows that people born in June, July, or August—conceived in the autumn and winter—tend to have a higher risk of being overweight. Conversely, those born in September – conceived in December – are less likely to struggle with obesity.
Scientists speculate that cold temperatures at the time of conception may trigger specific genes in men related to metabolism and fat storage, which could then be passed on to the child.
However, experts emphasize that this research is still in its early stages.
Diet, physical activity, and lifestyle choices have a much greater influence on obesity risk than the month of conception.
