Response: The usual eating pattern of most people in modern societies is breakfast, lunch, dinner plus a snack(s) every day. Animals used for most biomedical research – rats and mice – are usually fed ‘ad libitum’ (food is always available for them to eat). During the past 25 years, myself and the many scientists who trained in my laboratory discovered that when rats or mice are fed intermittently such that they have no food every other day or eat only during a 4-6 hour time period each day, their overall health improves in many ways. Animals on such intermittent fasting (IF) regimens exhibit signs of slowed aging and they live much longer than those fed ad libitum.
The editors of the New England Journal of Medicine invited me and Rafa de Cabo (a former postdoc in my laboratory at the National Institute on Aging) to write this review article for two main reasons. First, there have been a sufficient number of studies demonstrating the health benefits of IF in humans and knowledge of the underlying mechanisms to justify a review article. Second, many physicians are being asked about IF by their patients and the physicians are not privy as to if they should recommend IF and how to prescribe specific IF eating patterns and follow-up to increase the likelihood that the patient will be successful in changing their eating pattern.

Response: We found that many children who were planning to travel internationally were eligible for MMR vaccination prior to departure but often did not receive it - especially if they were aged 6 months to 6 years. That is because most children do not routinely receive their first dose of MMR till 12-15 months of age and their second dose of MMR till 4-6 years of age. However, ACIP recommendations are different for children who are traveling internationally. The risk of being infected with measles is much higher outside of the US, so it is recommended that children older than 1 year have had 2 MMR vaccinations and that children 6-12 months receive 1 MMR vaccination prior to travel. MMR vaccination is a safe and effective way to greatly reduce the risk of measles infection.
