We all know that crash diets are unhealthy - but - what is the most weight you have lost during a 'crash diet' and over what time scale?
How long did you sustain it, how much did you lose and how much have you since put back on?
This is just out of interest, given the number of sites that pop up promising quick results - just wanted to know if anyone actually tried and managed to get to their goal and then sustain their new weight.
