Just in case you were wondering, Olympic swimmers eat A LOT of food.

Conventional wisdom dictates that you shouldn’t eat half an hour before you go swimming. But what if you’re an Olympian and you need energy to swim really, really fast?

And what of the old adage, ‘you are what you eat’? Are our swimmers munching on gold medallists of old? Seriously, has anyone seen Kieren Perkins lately?

We’re fairly certain Mack Horton wasn’t chomping on the bones of the former champ before he won the 400m freestyle, but it does beg the question: WHAT ARE THESE PEOPLE EATING?

All pretty excited to be getting our Olympic uniform! #roadtorio #oneteam

Short answer: CARBS. Slightly less-short answer: A LOT OF CARBS (and a bit of protein).

After winning gold last night, America’s Michael Phelps reportedly indulged in just under half a kilo of pasta, which is around four times what an ordinary person might eat at dinner — or, I guess, twice what an ordinary person with a hangover might swallow.

As for Horton, well, it appears yesterday he smashed six times the cereal I managed on my Monday morning.

Basically, it’s important for athletes to replenish all the energy they’re burning in the pool.

It’s a bit more complex than that though, according to Dr Helen O’Connor, a sports dietitian who was in charge of the nutrition kiosk at the 2000 Sydney Olympics.

“An athlete’s fuelling strategy plays just as much of a part as their overall strategy,” Dr O’Connor told Mamamia when we spoke with her last week.

“What they eat, when they eat, both food and fluid as well as lifestyle considerations (such as getting enough sleep and beating stress) play a part.”

“Generally they’ll consume around 1600 through to five or six thousand calories daily, depending on the size of the athletes.”

While it varies across sports, Olympians will often taper their eating habits as they taper their training habits in the lead up to their events.

Some also supplement their diets with vitamins, protein powders and gels.

But what are they eating solids-wise?

Well, normal healthy stuff… with a little bit of junk on the side. They’ve earned it.

“It’s healthy eating. Fresh produce, fresh fruit and vegetables, lean meats like chicken. Carbs and protein are important for recovery,” Dr O’Connor explained.

“So depending on the type of training, bread, rice and pasta would be eaten in the few days leading up to the event.”
