Brian Sheldon, a social worker from the University of Exeter, in England, suggests this loss of interest can be attributed, at least in part, to the fact that early experiments produced little evidence of positive outcomes.
Although the ultimate outcomesof the low-fat and low-carbohydrate diets in the experiments were the same, in that people lost similar amounts of weight over the course of a whole year, this is unlikely to deter the hordes of Atkins aficionados who swear by the diet.
