We also examined different patterns of weight change among registry participants followed over time. We were particularly interested in evaluating whether participants who gained weight between baseline and year 1 were able to recover over the subsequent year. We found that few people (11%) recovered from even minor lapses of 1–2 kg. Similarly, magnitude of weight regain at year 1 was the strongest predictor of outcome from year 0 to 2. Participants who gained the most weight at year 1 were the least likely to re-lose weight the following year, both when “recovery” was defined as a return to baseline weight or as re-losing at least 50% of the year 1 gain.
