A: Diet and fitness are important considerations. Recent studies have shown that efforts to control weight and improve fitness can reduce the triggers of atrial fibrillation (AFib), and the duration of AFib episodes once they occur.
Studies in a group of patients with a body mass index higher than 30 who underwent a structured weight-loss and fitness program have seen a very significant benefit with a loss of about 10 percent of body weight.
With respect to specific dietary advice, reducing sugar intake is important as diabetes and obesity are significant risk factors for AFib.
There is no evidence from well-controlled clinical trials supporting the use of dietary supplements as effective treatments for AFib.
