A follow-up study on the impact of fathers' diet on offspring found that men-to-be fathers were more likely to develop obesity if they became obese due to overeating before the next generation  This probability had little to do with the mother's weight, while when the father-to-be was starved and experienced the threat of hunger, his children were more likely to develop cardiovascular disease
If the child's father suffers from cardiovascular disease, the child's chances of getting the disease in adulthood will be greatly increased
 As a result, the study suggests that the diet of fathers-to-be affects the health of their offspring
