"All the sugars that I was eating were found in perceived healthy foods, so low-fat yogurts, and muesli bars, and cereals, and fruit juices, sports drinks... These kind of things that often parents would give their kids thinking they're doing the right thing."
Except within just three weeks, Gameau's doctor told him he had already begun to develop fatty liver disease - the most severe of outcomes of which is liver failure. The physician also branded his level of mental functioning "unstable".
According to News.com.au, Gameau consumed 40 teaspoons of sugar a day on average - slightly more of that of the average teenager worldwide.
The World Health Organization (WHO) indicates that a healthy adult should aim to include no more than 25grams of sugar a day, or six teaspoons.
Far from the giant Big Mac burger of Spurlock's final meal, Gameau's last dish of the project was more akin to that of a child's school lunchbox - a jam sandwich, fruit juice, a biscuit bar and a handful of snacks.
"The last meal was for all the people out there, especially parents, who are led to believe they are doing the right and healthy thing for their children," he said.
"They are making an effort yet are horribly let down by the lack of integrity in marketing and packaging strategies."
However, he went on to explain that findings of his experiment didn't suggest we needed to cut sugar completely from our diets, but rather be more aware of where it has been added.
"Sugar's now in 80 per cent of the processed food we're eating," he said. "If we can remove that, that's the first step towards making a change."
As well as the immediate health effects of consuming excess sugar, links between sugar and a higher risk of developing cardiovascular disease - one of the leading causes of death in the UK - and type 2 diabetes also exist.
That Sugar Film, which also features appearances from Stephen Fry and model Isabel Lucas, will be released in Australia in February 2015.
