Elite runners (800m, and up) or race walkers (20K, 50K), please take this diet survey from top sports nutrition researchers. You'll learn for yourselves, and help others learn too: 
"It is possible that a different message, one encouraging physical fitness, may do more to improve individual and population health than continuing to advise weight loss when that message is increasingly ignored." Edward Livingston, MD, JAMA issue Obesity 
"At least marathon runners can rejoice ... reductions in mortality and CVD risk began to plateau at 1250 minutes/week of moderate-intensity physical activity, but no adverse effects were observed in the 9000 participants who reported >2500 minutes/week"
RIP Terry Laughlin, master swim coach & founder of Total Immersion Swimming. He mixed art, science, Zen, and had an insatiable curiosity.
@LdnPacers Thanks for the wonderful memories. Amby Burfoot
