I started the diet for the same reason as I've suspected for quite some time that my hypertension issue was somehow metabolic related. Without any meds my BP runs about 200/120. The only med I can take right now that does anything only gets it down to the 170/100 area. Three weeks into Paleo, it was down to about 118/84. In that time I lost only 7 lbs., which only represents a little over 2% of my total body weight but my well intended but clueless doctor insisted that the weight loss is why my BP dropped so sharply. I reminded him that my blood pressure problems started when I was fit and thin and in my early 20s and that the reason I thought my BP went down so quickly and sharply this time was because of the reduction in carbs. He scoffed at that but not wanting to argue he just said, "Well, whatever you are doing is working so just keep doing it."
When is the medical community going to get their collective brain wrapped around the fact that our crappy modern diet is killing us? I guess there's no money in that though and as they say, "follow the money."
