There are articles about this latest diet by Mosley in The Times and The Radio Times. His long-term maintenance strategy is that the dieters should be eating 3/4 of what they are before they began the 800 calories regime, preferably sticking to Mediterranean diet principles.

I am surprised he said he lost weight and reversed his type 2 with his Fadt800 diet as back in 2012 he said he had done this with his 5:2 version of intermittent fasting.
