With Britain set to go sporting mad as the Olympic Games approach, we show you some tasty and nutritious ways to eat like Team GB.

By Diana Pilkington During the Beijing Olympics, rumour had it that US champion swimmer Michael Phelps consumed a whopping 12,000 calories a day.

He has since dismissed this story as "all a myth", dashing the hopes of would-be gluttons everywhere, but athletes of his calibre nonetheless need more food than the average person to fuel their tough regimes.

Alex Popple, a performance nutritionist at the English Institute of Sport, is working with the British Olympic swimmers as the 2012 Games approach.

He explains: "We try and make their diet match their energy requirements and protein needs. Their diet is generally higher in carbohydrate compared to the average person because they're expending a lot more energy on a daily basis.

"They deplete their stores of muscle glycogen during training, and eating more carbohydrate will help replenish them more quickly.

"It's ultimately about allowing the athletes to come back and train as hard as they can in every session so they can get long-term gains in performance."

With this in mind, swimmers in training will eat three or four main meals a day, with recovery shakes and snacks to top up their energy levels in between.

Calorie-wise, they tend to consume about double that of the average person - which means around 5,000 a day for men and 4,000 for women.

Main meals should include complex carbohydrates - the starchier carbs like potato that are rich in other nutrients - and a high-quality protein source. Think chicken fillets or prime cuts of beef rather than sausages or pork pies.

"Protein provides the building blocks to allow the muscles to adapt to the training so they become faster, stronger and fitter. Every time athletes train they damage the muscle, so the protein helps the body repair it," says Popple.

He also advises the swimmers to include one or two servings of fruit or vegetables per meal so they can stock up on essential vitamins and minerals.

As elite athletes follow strict timetables and can have limited financial resources, meals that can be cooked and eaten in under an hour and cost less than £5 to make are also a winner. And if it tastes good, so much the better.

"Athletes are humans with preferences and dislikes," says Popple. "We try and make sure the recipes we suggest meet all the performance nutrition essentials and requirements, but that they are also tasty. If not, you won't get a lot of athletes who want to eat it."

Day in the diet Although all athletes' needs are different, here's a snapshot of what a performance swimmer might eat during a typical day of training...

6am: A medium-sized breakfast of cereal or toast before training.

7am-9am: Sports drinks to hydrate during the early-morning training session, and a recovery shake of protein and carbs afterwards.

10am: A second, more substantial breakfast, such as scrambled eggs, toast and beans and a fruit salad with yoghurt. Then they may sleep for a few hours to help the body recover.

1pm: A lunch of pasta, cous cous, rice or potato with salad and a high-quality protein such as chicken.

3pm: Some swimmers will have a high-carbohydrate snack to fuel up for the evening training session, such as bananas, bagels, toast with jam or cereal bars.

4pm-6pm: Sports drinks during training and another recovery shake afterwards to prevent hungry athletes from over-feeding when they get home.

7pm: An evening meal combining complex carbs and a different protein source from that eaten at lunch - perhaps a red meat to boost the athlete's iron intake.

9pm: Some swimmers will have a supper of cereal or toast. Nutritionists encourage them to have a milk-based meal that will help the body recover during sleep.

What the athletes like to eat...

:: Matt Holland, water polo goalkeeper, says: "Half an hour before and after training is when we've been told to eat our sweet stuff, so after training I'll have a chocolate bar. That's my sweet and I don't have it at any other time of the day."

:: Louisa Sawers, Kayak 4 canoe sprinter, says: "I do a lot of baking so I enjoy experimenting with new recipes. I think it's just keeping track of what you're eating and knowing what works for your body. You've got to have treats. Chocolate's mine. Every girl has got to have chocolate."

:: Yamile Aldama, triple jumper, says: "I like seafood and a lot of salad. I eat everything. I like ice cream which is my guilty pleasure but I eat healthily. I don't believe in diets but you have to eat sensibly."
