For example, in one study published in the International Journal of Sports Physiology and Performance , when bodybuilders prepared for competition by lowering their body fat, their heart rate dropped to 27 beats per minute. Too-low heart rates, called bradycardia, can lead to dizziness, passing out, and cardiac arrest. Meanwhile, other electrolyte imbalances due to too-low of a body-fat percentage, not to mention caloric intake, can lead to “cardiac arrhythmias and sudden cardiac death," he says.
