Effects on Functions of Heart

According to a research by the Weill Cornell Medical College, rapid weight loss puts the heart in danger by increasing the risk of heart attacks. Here’s how the heart’s functions are affected by rapid weight loss.

  • A strict workout regimen may disrupt heart’s primary function of pumping blood and oxygen throughout the body. In a quest to lose weight quickly, the heart may not be able to adjust to the changes introduced impromptu.
  • When you stick to a low calorie diet, the body may not get sufficient amount of nutrition. If the body fails to utilise and convert proteins into energy because of a strict weight-loss regimen needed for its functioning, the human heart could be severely damaged.

  • With a change in weight, the blood pressure and heart rate also change. The changes may make one experience irregular heart rhythms, which could lead to heart failure.
  • Anorexia nervosa is an eating disorder that may occur as a result of a low calorie diet.  Limiting calorie consumption to the point of starvation raises the risk of heart diseases considerably. Reports by the University of Maryland Medical Center suggest that long-term complications of anorexia include high or low blood pressure, irregular heartbeats and a possible heart attack.
  • Crash diets for quick weight loss may be fatal as they are likely to lead one to death from heart arrhythmias or irregular heartbeat. This happens when liquid formulas for weight loss fail to provide adequate nutrients to the body.

It is important to consider one’s heart rate when opting for weight loss products as doing so will keep one fit to exercise and burn the calories required for weight loss. If you are opting for a rapid weight loss program, it is important that you get your heart rate regularly and closely monitored by a doctor before, during and after the weight loss program. Should there be no hurry in losing weight, it is safe to opt for a slow but steady weight loss program. Besides, following a healthy weight loss program keeps the side-effects at bay.

The American Heart Association suggests weight loss for both cardiovascular health and aesthetics with a healthy diet (including plenty of fresh fruits/vegetables, whole grains and fat-free or low-fat dairy products) along with moderate physical activity.
