I am doing the lchf diet and have been increasing my runs everyday to the point that I run about 2 hours plus daily at a 9 minute / km pace. I noticed that my heart rate was a bit elevated in daily runs and that although I was eating close to no carbs daily my weight loss stalled and was even beginning to creep slowly up.
I heard from one of Jimmy Moore's podcast that there are some research that show that over exercising might even slow down or lessen the basal or resting metabolic rate. How true is this ?
