both produced by the same guy, virtually same calories, same process as in total food replacement.
although CD has more flavours, and different options - i.e total food replacement and food included.
sounds like an ideal alternative to LT at first, but when i moved over, i found the better flavours and the option to eat too much temptation, and found it harder to follow! weird i know.
But with LT - there is no option, there fore no temptation, and the stuff tastes so vile you dont want anything after it! lol
after 14 weeks on LT I thought cd would be a walk in the park, but it was harder for me, some find it better, depends on your will power and resolve really.
good luck and well done on wk 1
