It's been on the news recently as a chap by the name of Michael Mosley has used the method to lose a stone in five weeks for a Horizon documentary. That in itself is a massive achievement. Losing a stone would be enough to notice a difference and would be a great motivator to keep going to reach your target weight.
A strong word of warning, to anyone reading this, particularly those that are pregnant or diabetic, please seek medical advice before trying the fasting diet. Michael was monitored by a medical team while he was doing this. Proper tests have yet to provide proof that a fasting diet is beneficial in any way.
