What would cause my resting heart rate to rise over time?

Hi everyone,

Over the last month, I've lost ~8 lbs (1000 cal deficit.) Over the last week, I decided to increase my protein intake. Perhaps this is the cause to my increased resting heart rate? Should I be worried about this? I already have an appointment with my doctor for a physical, just to make sure things are all okay with my bloodwork.

Thanks for your reply. I ran a very hilly 10k on Sat (great cow harbor). Made the mistake of running another 10k on Sunday. The increase in the resting heart rate helped me avoid the mistake of keep running. Down to 56 today. Will start back up on Monday.
