Maybe Dr. Atkins was right: a big new study says a low-carb—high fat, high protein diet—is better for us. We’ll look at what that means.
Latest headlines in the unending stream of advice from science on your diet: ditch the carbs, grab the fats and protein. Years ago, fat was the taboo. People fled to carbohydrates. And boom went the obesity. A new study in the Annals of Internal Medicine now reports that people who avoid carbs and eat more fat and protein end up with better heart health and lower cardiovascular risk. Even when it’s saturated fat. If that makes you want to grab a juicy rib-eye steak, it’s not that simple. But refined carbohydrates are getting the boot again. This hour On Point: protein and fat versus carbs, again.

From Tom's Reading List
Annals of Internal Medicine: Effects of Low-Carbohydrate and Low-Fat Diets: A Randomized Trial — "Low-carbohydrate diets are popular for weight loss, but their cardiovascular effects have not been well-studied, particularly in diverse populations. A low-carbohydrate diet [can be] more effective for weight loss and cardiovascular risk factor reduction than a low-fat diet. Restricting carbohydrate may be an option for persons seeking to lose weight and reduce cardiovascular risk factors."
New York Times: A Call for a Low-Carb Diet That Embraces Fat -- "Diets low in carbohydrates and higher in fat and protein have been commonly used for weight loss since Dr. Robert Atkins popularized the approach in the 1970s. Among the longstanding criticisms is that these diets cause people to lose weight in the form of water instead of body fat, and thatcholesterol and other heart disease risk factors climb because dieters invariably raise their intake of saturated fat by eating more meat and dairy."
USA Today: Low-carb diets: Studies differ on whether they are best — "Low fat or low carb, Atkins or Ornish, Jenny Craig or Weight Watchers – which diet is best for weight loss? Two new studies offer ammunition for those who say the popular low-carb approach is superior and for those who say all diets are pretty much the same."
