Is sugar really the culprit of the obesity epidemic?
However, there is level I evidence that fructose is not uniquely obesogenic, and Robertson’s analysis of Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) data has major flaws.
Two systematic reviews of the evidence investigating the effect of fructose on weight have been recently published.
The first investigated the effect of consuming 46–176g of pure added fructose a day on weight and determined that no significant effects are seen when adults consume <100g (24 teaspoons) per day. Consuming >100g a day of pure added fructose on top of a normal diet may lead to a modest rise in body weight of 0.44kg a week, most likely due to the extra kilojoules.1
The most recent review found consuming <104g of fructose had no statistically significant effect on body weight (-0.14kg) in ideal-weight
