Most modern nutrition advice is gibberish, mostly because a lot of it arises from poorly done studies. In this randomized trial (a rarity in nutrition research), Australian scientists randomly assigned middle-middle aged and late middle aged men to a fad diet (5-2) and to just cutting overall calorie intake daily. The cut calories group did better in short-term weight loss and body composition improvement. Big surprise.

The study has no long-term implications. It lasted only six months, measured no health endpoints, and, obviously, had no discernible impact on mortality, which is the endpoint that concerns most of us. If you do nothing other than the 8 ideas I outlined recently in my essay for Whole Life Challenge, you’ll get your New Year off to a terrific health start…and, if you care to, you can use those steps to cut calories, too. At the end of the day, it’s all up to you.

The Telegraph: 5:2 diet no better than cutting calories, study finds.
