I have been doing the Atkins program since the beginning of January with only limited success (only 10 pounds lost in 3 months)! So, I decided to go on the "fat fast" described to overcome metabolic resistance. I ended the 4 day "fast" last night and started back on the Induction phase this morning. Now I'm experiencing heart palpitations which are causing me to cough and feel a little nauseated. I've had 2 episodes so far. Has anyone else experienced these problems?
