Many people believe that weight lost quickly is quickly regained. But a new randomised trial has found no long-term difference in weight regain among people who lost pounds slowly and those who did so quickly.

Australian researchers randomly assigned 200 obese people to one of two groups. The first followed a severely calorie-restricted diet for 12 weeks, the second a moderately restricted diet over 36 weeks. The study is online in Lancet Diabetes & Endocrinology.

The researchers then placed all those who lost at least 12.5 per cent of their weight 51 of the gradual weight losers and 76 of the rapid losers on a weight maintenance diet. After three years on the maintenance diet, there was no significant difference in the amounts of weight regained: 71.2 per cent was regained on average by the gradual losers, versus 70.5 per cent by the rapid losers.
