In a study of the weight loss rate, researchers found that the time taken by people to lose weight does not have any significant influence on the successful maintenance of the new weight. The participants were studied over a span of 3 years, during which they regained certain percentage of the lost weight irrespective of how long they took to lose it. The study was carried out by a team of researchers from Australia, and the lead author of the report was Joseph Proietto.
The researchers say that the study reveals the need for the revision of the current guidelines that advise slow weight loss for sustainable result. Instead, improvement of the methods for maintenance of weight-loss has to be the focus. Obesity or overweight is perceived as a behavioral issue by many, and the belief that steady and gradual achievement of weight-loss is more sustainable seems to have originated from that perception. Indeed, habits change slowly and the more graduated the process is the greater it sustainability is. However, obesity is caused not just because of inappropriate lifestyle, it is significantly genetic too.
Scientific evidence does not back the claim that slow weight loss makes maintenance of weight more sustainable, according to Proietto. Irrespective of how the weight is lost, individuals generally have difficulty in maintaining the new weight as many of them regain much of it.
A trial was chalked out by Proietto to test the influence of the weight-loss rate on sustainability. The study was divided into 2 parts – weight loss and weight maintenance. There were 2 weight-loss programs – rapid and gradual. The study was carried out on two hundred obese adults equally divided into the 2 weight-loss programs. The 1st part lasted for 36 weeks. In the 2nd phase of the research, the participants were provided with individualized diet plans and instructed to consult a dietician after every twelve weeks.
The researchers found that 81% of the participants, who were on the quick weight-loss program, achieved the target-weight in comparison to only 50% of their counterparts. In the 2nd phase of the research, most of the participants from both the groups regained around 71% of the lost weight. Thus, it was concluded that the time required to lose weight had no significant influence on the maintenance of the new weight.
The study made some other significant revelations. Only about 15% of the people may actually be able to lose their weight as well as maintain it with the help of exercise and diet. The exercise that is needed to maintain the weight post weight loss is extremely tough to be incorporated into the contemporary lifestyle. Pharmacotherapy may be a considerable option for those who are regaining weight despite rigorous effort. However, there is no strong evidence to establish that pharmacotherapy does offer sustainable success. The weight-loss rate did not affect appetite and hunger of the participants either.
Proietto said that appetite suppression may be considered after successful achievement of weight-loss, none of the many effective medicines have been properly tested.
