Dr Michael Mosley's unusual diet switch for lower weight and better heart health

In the 1970s and 1980s we were all told to avoid certain foods, but Dr Mosley has made the switch back thanks to recent science

Health and fitness guru Dr Michael Mosley says one diet change he has made himself that sounds like it shouldn't work actually helps guard against a condition linked to obesity and diabetes, as well as reducing the risk of strokes and heart attacks.

The creator of the Fast800 diet says he has made the switch back to full-fat milk and full-fat yoghurt, as well as butter, after years of avoiding them in a bid to stay healthy. Writing in the Daily Mail, Dr Mosley said full-fat dairy fell out of fashion with people trying to stay fit in the 1970s when we were told it would block arteries and cause weight gain.

The diet guru says that full-fat cheese is a nutrition "powerhouse" and that some healthy fatty foods have been demonised.
