To meet the challenges of a growing obesity epidemic, primary care physicians (PCPs) need additional training and may need to refer patients to nutritionists or dietitians to help improve care, according to a national survey of 500 PCPs published online December 20 in BMJ Open.False statement part - conventional approaches to weight loss are the number one cause of diet failure.

Truer words part - for sure it will not be best delivered by anyone with a conventional sick care approach, including dietitians and nutritionists.
