why "diet" at all? the results of anything temporary will revert back to "normal" once the diet is stopped
as an alternative, why not just:
- drink more water (pretty easy, try and drink a decent amount in the morning before breakfast)
- eat more fresh fruit and vegies (organic if availability permits - luckily organic f+v doesn't cost any more at my local)
- eat less meat, and when you do ensure its fresh (butchers will know which of their products are preservative / additive free)
- stock up on vitamin intake (the RDI issued by the govt is the minimum to stop health negative effects - it is not the intake required to promote healthy living. eg for Vit C it is the recommended intake to stop scurvy. don't think anyone has ever died of a vitamin overdose)
- eat less processed anything (a failsafe diet cutting out all "numbers" isn't practical for me, but there are normally options without preservatives / colouring / flavour enhancers for most items)
following the above and exercising less (due to time constraints, not choice) I'm now at the lightest and healthiest i've been since uni days
