Of the forty* men who have been elected to the office of U.S. president, the average weight of U.S. presidents has been approximately 189lbs (86kg). The weight range has been between 122lbs (55kg) and 332lbs (151kg), meaning that the heaviest president, William Howard Taft, was almost three times as heavy as the lightest president, James Madison (who was also the shortest president). Although Taft weighed over 300lbs during his presidency in 1909, he did implement a fitness and dietary regimen in the 1920s, that helped him lose almost 100lbs (45kg) before his death due to cardiovascular disease in 1930. Increase over time The tallest ever president, Abraham Lincoln (who was 6'4"), actually weighed less than the presidential average, and also less than the average adult male in the U.S. in 2018. It is important to note that the average weight of U.S. males has gradually increased in the past two decades, with some studies suggesting that it may have even increased by 15lbs (7kg) since the 1980s. The presidential averages have also increased over time, as the first ten elected presidents had an average weight of 171lbs (78kg), while the average weight of the ten most recent is 194lbs (88kg). Recent presidents In recent years, the heaviest president has been Donald Trump, who weighed 237lbs (108kg) during his first term in office; however medical reports published in June 2020 show that he gained 7lbs (3kg) during this term. There was also controversy in 2018, when it appeared that Trump's official height had been increased from 6'2" to 6'3", which many speculated was done to prevent him from being categorized as "obese" (according to his BMI). In the past half century, George H. W. Bush and Bill Clinton were the only other presidents to have weighed more than the presidential average, although both men were also 6'2" (188cm) tall. President Joe Biden weighs below the presidential average, at 177lbs (81kg).

United States US: Prevalence of Underweight: Weight for Age: Male: % of Children Under 5 data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s United States – Table US.World Bank.WDI: Health Statistics. Prevalence of underweight, male, is the percentage of boys under age 5 whose weight for age is more than two standard deviations below the median for the international reference population ages 0-59 months. The data are based on the WHO's new child growth standards released in 2006.; ; World Health Organization, Global Database on Child Growth and Malnutrition. Country-level data are unadjusted data from national surveys, and thus may not be comparable across countries.; Linear mixed-effect model estimates; Undernourished children have lower resistance to infection and are more likely to die from common childhood ailments such as diarrheal diseases and respiratory infections. Frequent illness saps the nutritional status of those who survive, locking them into a vicious cycle of recurring sickness and faltering growth (UNICEF, www.childinfo.org). Estimates of child malnutrition, based on prevalence of underweight and stunting, are from national survey data. The proportion of underweight children is the most common malnutrition indicator. Being even mildly underweight increases the risk of death and inhibits cognitive development in children. And it perpetuates the problem across generations, as malnourished women are more likely to have low-birth-weight babies. Stunting, or being below median height for age, is often used as a proxy for multifaceted deprivation and as an indicator of long-term changes in malnutrition.
