WEIGHT TO GO: A nasal de­vice which im­pairs abil­ity to smell could help obese peo­ple lose weight, re­searchers have claimed. The soft sil­i­cone con­trap­tion is in­serted in­side the nos­trils, en­abling users to con­tinue breath­ing but caus­ing air to by­pass the ol­fac­tory. The de­vice, named NozNoz, was found to aid weight loss in obese peo­ple un­der the age of 50, ac­cord­ing to a pi­lot study pre­sented at the Euro­pean Congress on Obe­sity in Vi­enna, Aus­tria. A pi­lot study found that those who used the de­vice ev­ery day for five to 12 hours lost an av­er­age of 8.3kg in 12 weeks, com­pared with 4.3kg in the placebo group. Mean­while, un­der 50s who used it for more than eight hours a day lost on av­er­age 10.1kg dur­ing the trial. This may be be­cause abil­ity to smell de­clines with age, typ­i­cally from the age of 50, the re­searchers said. PREVENT CANCER: Drink wa­ter and avoid sug­ary drinks to help prevent cancer, lead­ing sci­en­tists have urged. The call comes as part of a string of rec­om­men­da­tions on health and life­style choices, dubbed a “blue­print to beat cancer”, pub­lished by the World Cancer Re­search Fund (WCRF). Pre­vent­ing obe­sity forms a sig­nif­i­cant part of the ad­vice, with be­ing over­weight likely to over­take smok­ing as the “num­ber one risk fac­tor for cancer” within decades, the or­gan­i­sa­tion warned. There is now strong ev­i­dence ex­ces­sive weight is the cause of at least 12 can­cers, five more than when the last WCRF rec­om­men­da­tions were pub­lished in 2007, the au­thors said. For the first time sep­a­rate rec­om­men­da­tions have been in­cluded on lim­it­ing con­sump­tion of soft drinks — urg­ing peo­ple to “drink mostly wa­ter and unsweet­ened drinks” — and pro­cessed foods. Peo­ple should re­duce their con­sump­tion of fast food and those high in fat, starches and su­gars to help con­trol calo­rie in­take, it states. The num­ber of new cases of cancer is ex­pected to rise by 58% to 24 mil­lion glob­ally by 2035. Around 40% of can­cers are es­ti­mated to be pre­ventable, the au­thors said.
