She weighed more than 100kg when the photo was taken four and a-half years ago, but now she has shed 37.4kg both she and her husband Daryl could fit into her wedding dress and zip it up, Mrs Adam (39) said yesterday.
To overcome Max's photo confusion, they had decided to sit for a family portrait, Mrs Adam said.
Mrs Adam, who has been a Weight Watchers leader since last year and leads two sessions a week and helps out for another two, won the national award in the staff category.
She and fellow Dunedin award winners, who had a combined weight-loss of 140kg, had not been in the same sessions, but all praised the input of their leader in common, Norma Renfree, who was unable to join them for a celebratory photo yesterday as she is in Taranaki helping out with a new grandchild.
All agreed weight loss had allowed them to lead much fuller and more enjoyable lives.
Mrs Adam said it was great to be able to do things such as go on a slide with Max without fear of it breaking.
Mary-Anne Kirkness (30), who lost 47.4kg, agreed, recalling trying to go down a dinosaur slide when only one buttock would fit.
She has kept at her healthy weight for two years and won the lifetime member category.
She has also managed not to gain weight as a result of giving up smoking, with Ms Renfree's help.
Part of her success was due to not denying herself foods such as fish and chips, but eating them only in moderation.
Otago Polytechnic lecturer Michael Greaves (31), who won the men's slimmer of the year category with a weight loss of 28.4kg, said the loss enabled him to start paying attention to the things he did, instead of worrying about the way he looked.
He had tried to lose weight several times, but it was a photo of himself that was the trigger to his involvement with Weight Watchers.
Potter Dawn Palmer (62), who won the senior category, said the 26.7kg loss had turned her health around.
Everyday movements such as walking and getting in and out of the car had been a trial, but now she was no longer on medication and could even load her kiln without hurting herself.
All four agreed the hardest thing to do was to ask for help and that ongoing support was vital.
Mr Greaves said it was also important to keep perspective, accepting there would be bad weeks, but not giving up because of them.
