The diet is on track for New Zealand Olympic weightlifter Richard Patterson, who competes today in the 77kg class in Beijing.
Patterson says the strict controls put in place by his coach are paying off.
He came in at 81 kilos and had to lose four kilos. He's now sitting at 79 and is hoping to lose another kilo then will dehydrate the last kilo.
Patterson, who is competing at his first Olympics, says the athletes easily lose a kilo overnight in the humidity.
His fellow weightlifter Mark Spooner came fifth in his 69kg heat on Monday, which wasn't good enough to progress.
