Metabolic diet - any good??

[DorsetLass]

I have just started some personal training and the girl I'm working with reccomends the metabolic diet. She does full body/diet analysis for you, then plans first few weeks (charging approx £90). Reluctant to shell out any more cash, but stuggeling to rid final post baby stone (nearly three years on!!). Any one tried it? Any good or just another fad??
