A study published in the March issue of the American Journal of Clinical Nutrition has challenged what we have been following for decades that saturated fats are bad for our hearts. The study found inadequate evidence linking saturated fat intake to cardiovascular disease or coronary heart disease.

The famous Atkins Diet has been refurbished with a motive to make it easier to understand and maintain. "The New Atkins for a New You", allow dieters to eat more vegetables than the old version did. But the diet's core concept that carbohydrates, not saturated fat, are what make us fat stays intact.

The new book, written by Eric Westman, Stephen Phinney and Jeff Volek, directs dieters through four phases, from "Induction" through "Lifetime Maintenance". Westman says that the Induction phase allows dieters to eat some vegetables: leafy, fiber-filled and unstarchy ones such as cauliflower and spinach.

The new Atkins also advises to include more fruits, grains and legumes to the diet.

Atkins also encourages sodium consumption. Westman explains, "If you don't have a salt-sensitive condition like heart failure, salt in the diet is not restricted on Atkins".

It has been seen that people who follow Atkins had improvements in cardio metabolic risk factors such as triglycerides, good cholesterol, blood pressure, blood sugar.
