A high-pro­tein diet can aid fat loss by pre­serv­ing lean mus­cle mass and in­creas­ing sati­ety. But new re­search1 sug­gests there may be a down­side. The study com­pared di­eters con­sum­ing 0.8g of pro­tein per kg body weight (.75g is the rec­om­mended daily al­lowance in the UK) with those con­sum­ing 1.2g/ kg. Both groups shed con­sid­er­able amounts of weight and the high­er­pro­tein group did in­deed lose a lit­tle less lean body mass. How­ever, they ex­pe­ri­enced no im­prove­ment in in­sulin sensitivity – key in the pre­ven­tion of di­a­betes and other meta­bolic dis­eases – while those on the lower pro­tein in­take gained im­prove­ments of 25-30 per cent.
