Lots of veggies, lean proteins, and whole grains are on the menu

Team USA is comprised of athletes across a wide range of ages and dietary needs. Some, like alpine skier Resi Stiegler, have special dietary concerns like celiac disease.

Others try to go for the protein and leave the veggies. But Chef Chacosky has strategies of her own for dealing with veggie avoidance.

"I've learned to outsmart them a little bit and make sure I've got vegetables in everything, so they have to eat it anyway," Chef Chacosky told Mic.

Some athletes don't count calories at all, preferring instead to stick to general rules like not eating lots of refined sugar and getting plenty of lean protein and vegetables into their diets. Both Stiegler and fellow alpine skier and two-time gold medalist Ted Ligety told ABC News that this is their nutritional approach rather than rigorous calorie counting.

"We definitely try to eat more food than less food. I try to eat really healthy, a high-protein diet with lots of vegetables," Ligety said.
