I did the Tony Ferguson and lost 18kilo's in 5mths in the later end of 2007 ... but have since put on 10kilo's in the past 12mths ... mainly due to a lot of stress ... but i think i would have still put some on as having liquid breakfast & lunch is just simply NOT a normal way to eat ... and i was so dying to sink my teeth into any solid

After doing that for 5mths now when ever someone mentions diet shakes to me i instantly feel nauseous

I think doing it to lose no more than 10kilo's might be ok BUT i found getting past the first couple of months i developed a feeling of Guilt whenever i felt like wanting to eat something solid that wasn't in the form of liquid even if it were healthy solid food
