The checkup for the 71-year-old president would not include a psychiatric evaluation, Sanders earlier told reporters.
"Media reports about my eating and sleeping habits, as well as my own admission during the campaign that I could lose a few pounds, can only contribute to the concern".

The association suggests players walk the golf course instead of renting a golf cart. Bill Clinton, despite a weight problem, could run at an 8-minute-mile pace. George W. Bush traded running for mountain biking to preserve his knees. He is also the heaviest president in at least a generation and consumes a diet heavy with Big Macs, Filet-O-Fish sandwiches, fried chicken, pizza, well-done steak and two rounds of dessert.
