Whatever they eat in the Atkins household it is clearly working. With three World Cups between them brother Darren and sister Caroline are used to a diet of success. The Atkins diet.
Darren has a chance to add to that tally on Sunday when England take on New Zealand in the final of the World Rugby U20 Championship.
A member of last year’s winning World Rugby U20 Championship squad, he was called into the squad late but made a significant impact in the semi-final against South Africa, having also played as a replacement against Australia.
His sister Caroline, who played cricket for England women, won both the ODI and Twenty20 World Cups in 2009.
She was also member of the side which retained the Ashes on tour in Australia in 2008, and as Atkins explains competitiveness runs right through his family.
“To be able to match her tally would be amazing,” said Atkins. “To have four World Cups in the family would be unbelievable.
“We have an organisation system in the family so that if anyone slips up, they fall down the ranking system.
“My eldest brother played football at a high level, my middle brother played rugby at national league level and my other sister swam when she was younger.”
Atkins had been planning to go on holiday this week before unfortunate injuries to Sam Aspland-Robinson and Max Wright meant he had to shelve his trip and head out to Georgia.
The Bath wing now stands on the verge of a second world title.
“It's an amazing opportunity,” said Atkins. “I obviously got a medal last year but didn’t play in the final so to play on Sunday would be incredible.”
He made his senior debut for Bath against Bristol earlier this season and is delighted to be back involved with U20s.
“I’m just trying to take it all in, enjoy the experience and do as well as possible,” he added.
England take on New Zealand looking to seal their fourth World Rugby U20 Championship title in five years.
They have reached the final without five players who are with the senior squad in Argentina, while they have also lost another five to injury while in Georgia.
England are also looking to make history by winning the Six Nations Grand Slam and World Rugby U20 Championship in the same season.
Atkins hopes he can be a part of that history and match his sister's tally of double World Cup glory.
