Here some nice little story about the attitude of docs to low carb:
I've always had borderline high blood-pressure and although not VERY active last summer I walked to work every day (20 minutes one way), but ate 'normal' veggy food and A LOT of sugar stuff.
Then I twisted my ankle and was barely able to walk for about 8 weeks.
Decided to try to eat some more protein and cut down on the carbs.
Went to the doc to get a check up on my ankle and the bloodpressure.
Which was FINE for the first time in a long while.
Told the doc about the low carb and she flipped and said: 'only excercise will reduce bloodpressure'. I only pointed to my busted ankle and my crutches....
