Birmingham boxer Frankie Gavin insists his much-publicised struggle to boil down to the 60kg lightweight limit will not affect his chances of adding Olympic gold to the world title he already owns.

The 22-year-old from Yardley is currently completing preparations at the British team's holding camp in Macao along with the seven other members of the successful boxing squad.

Gavin insisted: "I'm feeling good and I'm sure I'm going to make the weight okay. Obviously it's been a struggle but as long as I'm sensible and continue to do the right things I'll be fine."

Gavin has been campaigning at the higher light-welterweight limit throughout this season with the telling exception of last November's world championships in Chicago, when he became the first ever British fighter to claim the title.

He hopes the more relaxed schedule at the Olympics - boxing on alternate days as opposed to consecutively - will enable him to live up to his billing as the pre-tournament favourite for gold.

Gavin said: "It felt a lot worse before Chicago because I hadn't made the weight all year and I didn't think I could do it. I was surviving mostly on fluids and energy bars and it was very tough.

"After my fights I'd have to train then I'd go to bed without eating. It was difficult but I came through it and if I did it in Chicago and still won, there's no reason I can't do the same at the Olympics."

Gavin has worked closely with Ricky Hatton's nutritionist Kerry Kayes in recent months and will have an army of dieticians monitoring his progress when he arrives in Beijing on the day of the opening ceremony.

He hopes his regime will dispel fears that the chances of one of Britain's brightest gold medal chances in Beijing could be scuppered by the scales rather than any lack of ability on his part.

"It's natural to have doubts before a big competition and that's nothing new for me," added Gavin.  "But as soon as I start that walk to the ring, things change. At that point I always know I'm going to come out on top."

Gavin is not set to make his Beijing bow until the third day of competition, with middleweight James Degale and light-heavyweight Tony Jeffries first up on the opening Saturday.

The entirely unseeded and potentially crucial draw for the boxing competition is set to take place in central Beijing on August 8, prior to the commencement of the programme at the Workers' Gymnasium.
