Firstly, the paper is not a gospel or oracle of truth. The papers is is based on extrapolations from evidence of other studies. It is not the presentation of dogmatic facts but more of a discussion paper.
Researchers behind the paper, published in the BMJ late on Wednesday, analysed data from more than 9,000 people from 37 studies that examined the effects of ceasing the drugs. On average, the participants took the medicines for 39 weeks and provided follow-up data for 32. The scientists extrapolated from the studies to forecast what would have happened after a further lapse of time.
The scientists acknowledged limitations in their work including that almost a third of the trials they surveyed had a high risk of bias. The populations in the drug and behavioural treatment programmes might have differed in potentially important ways, such as the degree of obesity and incidence of comorbidities, they added.
All diets tend to work, as long as people are on them and this includes when using WLI. Most people can successfully diet, the problems occur when they stop. Therefore it doesn't take a genius to surmmise that the same will be true for those on WLI. Much more recognition needs to be given to what the co-author of the paper said:
“Obesity is a chronic relapsing condition and it’s very clear that . . . some sort of intervention needs to continue if we’re going to sustain the benefits of these treatments.”
I hope that these articles, instead of encouraging all the ranting frothers to bang on about how fatties are lazy, greedy and bound to fail will actually stimulate more understanding of the problem of the epidemic of obesity we are facing and its multi-causal factors and how best we can deploy WLI and medications to tackle the issues - along with all the other things we should be doing too.
