Adding more sugar beyond the "bliss point" leads to a significant drop in desirability.įollowing the experiment, he returned to his previous diet, and the ill effects were largely and quickly reversed. The viewers are introduced to the " bliss point", a term coined in the 1960s which applies here to the amount of sugar you can add to a food to make it optimally desirable. It is suggested that artificial sweeteners may be no better. Interviews with experts attribute this change to the high level of sugar he was ingesting, and in particular suggest that fructose may be the main culprit. The sugar diet was selected such that his calorie intake was not increased from his normal diet. As a result, Gameau gained weight, grew lethargic, and developed fatty liver disease.


The film follows Gameau's experiment on himself, changing from his normal diet containing no refined sugar to a 'health-conscious' diet low in fat but high in sugar, equivalent to 160 grams (40 tsp) of sugar per day.
