hi karen!
i've been seeing a nutritionist for the last year (i was feeling very tired). she hads changed the way i eat. i used to grab food on the run_ breadsticks, a quick yogurt, an apple_ and that would be lunch.
she basically has increased my protein intake, lessened the number of carbs i consume and has changed the ones i do eat to whole grain and complex carbs (no white bread, white rice, etc). she also believes in frequent small meals/ snacks. this way, you never feel starved!
we normally cook lowfat, low salt meals at home anyway, so it was not such a big adjustment.
i think her "diet" or way of life is very similar to sugar busters and the zone combined.
maybe your best bet is to look into a book as a guide and use that?
i would be happy to fax you or mail any info/ sheets i have on this diet. you must remember though, it is tapered to my personal likes and dislikes.
i wish you the best of luck. please let us know how you do.
be well, sylvia
