There seems to be a lot of negativity on here. As others have said, this seems to be the Newcastle Diet which has gradually become established as one way to potentially reverse T2, This should be welcomed as a good thing if people can be encouraged to loose a lot of weight quickly. There are good words written about moving to a sustainable diet after the end of the initial phase. Again standard Newcastle Diet. Why not watch to see how well this works, and cheer the participants on? I am assuming that once this gets under way it will shine a spotlight on how successful different ways of eating are at keeping the weight off and maintaining metabolic health. At which point LCHF might get a chance to shine. However other eating approaches are also available and if they work, great! This forum generally loves LCHF but please remember that it isn't the only way, and it doesn't make all other approaches wrong.
