Paving the road to the games for most Olympic athletes are a stunning quantity of foods rich in proteins and carbohydrates. These food help keep the athletes trim and often slim as seen on TV.
Turkish javelin thrower Fatih Avan says that he is mindful of what he puts in his stomach while training for the 2012 Olympic Games in London.
Advertisement"I may have become an elite athlete with my good performances but I can only be a great athlete if I can win an Olympic medal," the Daily Mail quoted him as saying.
The 23-year-old complements his rigorous training schedule with a nutritional program which gives him a daily intake of 3,500 calories - mostly derived from protein.
"A good diet is essential for power. A correct and consistent diet proves its value in my training," he said.
Taekwondo fighter Bahri Tanrikulu is a three-times world champion and an Olympic silver medalist. The 32-year-old has his heart set on a gold medal at the London Olympics that will kick off on July 27.
He supplements his 3,000-calorie daily diet with legal ergogenics - performance enhancing supplements - and multivitamins.
"If I did not take these supplements, I would have to eat several kilos of meat, and dozens of pieces of fruit to meet my daily protein and vitamin requirement," Tanrikulu said.
"If I had to obtain the calories my body needs through natural foods, I would have to spend all my time eating instead of training," he said.
Nur Tatar is also preparing to compete for Turkey in the Games. This is her first Olympic event in taekwondo, and she is on a strict diet to shed several pounds to reach the exact weight category in which she will fight.
To accomplish her goal, the 22-year-old has reduced her daily calorie intake to mere 1,500 calories.
World champion weightlifter Mete Binay, aged 27, fuels up on a whopping 3,500 calories a day. He drinks at least two glasses of milk a day, and his diet is largely composed of red meat.
Binay indulges in sweet desserts and takes care never to miss a full breakfast. The weightlifter is also fond of organic food. Shortly before competition, he too starts supplementing his diet with ergogenic aids and vitamins.
Wrestler Elif Jale Yesilirmak, 26, adheres to a 3,000 calories-a-day diet, but her dietary program has a twist.
"Instead of red meat, I generally eat salmon," she said.
"I believe fish is more healthy and nutritional. And also lots of water. I drink a minimum of five liters (more than a gallon) of water every day," Yesilirmak said.
Merve Aydin, 22, is an 800-metre athlete who will run at the Olympics for the first time. Her daily intake is 3,000 calories. Although she is rigorously training for the Games, she remains guarded on the outcome.
"It is more important for me to realize my true potential and limitations. And do the best I can. I work hard and keep a careful diet," Aydin said.
