Fasting diets are silly. Your body just gets all confused. Just adjust your diet bit by bit and do more exercise (sometimes hard in a hot and humid climate I know). Most of us could do with cutting carbs more than anything (rice, bread, pasta ... and .... beer). Don't get too carried away though, you might get run over by a jeepney tomorrow.
(I go to the gym regularly and keep reasonably fit, I want to stay fit to stay mobile for longer in my life, I'm not quite 50 yet though).
