Twelve clinical trials with follow-up ≥12 months were used for the assessment. When comparing the popular diet vs. usual care, Weight Watchers was consistently more effective at reducing weight. In the head-to head trials, Weight Watchers, Zone, and Atkins helped participants achieve modest and similar long-term weight loss. When reviewing 24 month data, weight lost with Weight Watchers and Atkins was partially regained over time. The authors conclude that when it comes to popular diets, given the amount of conflicting and insufficient data, it is difficult to pinpoint which diet is most beneficial.
