Long term maintenance of weight loss with non-surgical interventions in obese adults: systematic review and meta-analyses of randomised controlled trials

BMJ 2014; 348 doi: https://doi.org/10.1136/bmj.g2646 (Published 14 May 2014) Cite this as: BMJ 2014;348:g2646

All rapid responses

Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles or when it is brought to our attention that a response spreads misinformation.

From March 2022, the word limit for rapid responses will be 600 words not including references and author details. We will no longer post responses that exceed this limit.

The word limit for letters selected from posted responses remains 300 words.

Re: Long term maintenance of weight loss with non-surgical interventions in obese adults: systematic review and meta-analyses of randomised controlled trials

Dear Editor
The article compares the role of physical activity and diet restriction combined as weight loss interventions. It wrongly assumes that physical activity is linked to weight loss. This is not strongly proven by any of the published literature. There are studies which only show mild association and for the short term. There is no long term impact of physical activity with weight loss. Weight gain is because of mainly over consumption of unhealthy food. It is not because of a lack of a physical activity. Physical activity recommendation is basically for "physical fitness" rather than prevention or treatment of weight gain.

The present systematic review did not appear to evaluate blood lipids profiles or cardiovascular parameters. An important consideration that appears to be downplayed and excluded.

Dear Editors,

If more hypnotherapy interventions for weight loss were included in this systematic review, lasting beneficial results on weight loss maintenance would appear far more evident. [1][2][3][4][5]
