I was interested to learn that America has had several "portly" presidents and that the country appears to be more propserous under these generously proportioned commanders-in-chief.
President William McKinley was no "lean-and-mean" president and put the United States on the gold standard.
Likewise, Howard Taft was on the heavy side, tipping the scales at over 300 pounds. During his tenure as president, the United States was both prosperous and peaceful.
Theodore Roosevelt had a hefty build. His presidency coincided with America's prestige and reputation reaching a high point around the globe.
One might speculate that a well-fed president made for a well-fed nation.
