Low-Carb Diet Linked to Lower Blood Pressure Both low-fat plan and Atkins-style regimen lead to weight loss By M.

(Flickr) (Newser) – Besides leading to weight loss, a low-carbohydrate diet helps lower blood pressure, according to a new study. Research subjects randomly assigned to a low-carb regimen lost about as much weight as patients following a low-fat plan and taking a weight-loss drug—the generic version of the medication marketed as Alli—but showed a significant improvement in blood pressure readings. "Weight loss was similar but substantial in both groups we studied, but blood pressure improved more in the low-carb dieters," says the lead researcher. "It's important to know you can try a diet instead of medication and get the same weight loss results with fewer costs and potentially fewer side effects."
