Hi. I am wondering if there is any risk to the heart when on the ChatDoctor diet. I have been taking ChatDoctor drops for 3 days and woke up this morning with a pounding heart. Could this be because of the ChatDoctor diet?  If so, is it the drops themselves, or the restricted calories that could be causing my heart to pound? I am healthy, 46, and would like to lose 30 lbs.
Chat Doctor diet is typically just 500 to 800 calories a day. As you are restricting your calories body may get deprived of regular electrolytes which body is taking, hence BP may fall and cause palpitation(tachycardia)_as you are taking only 800 calories, I may be possible that long fasting hours during night decreases your blood sugar levels and causes palpitation. Measure your fasting blood sugar next time you feel palpitation.
