In 2011, when I ate vegan and worked out at the gym 5 days a week, my blood pressure was averaging 140/90 with spikes as high as 150/100. Keep in mind I was only 187 pounds, 6' tall, and 32 years old. The doctor wanted to put me on blood pressure meds but I refused. In December, I started trying the paleo diet and noticed my blood pressure dropped to 125/78 in a couple weeks. So in January, I bought an Omrom BP monitor to record my daily blood pressure readings while eating 100% paleo. As you can see in the graph I posted from Facebook, I now average around 110/68. I still work out 5 days a week and now I'm actually gaining muscle after losing an initial 20lbs off my gut from Jan - April.
