The Claim

A 6.1% reduction in body fat mass in obese adults achieved through the use of Prolibra™ whey protein during a 12-week calorie-restricted diet exceeds the 5% threshold associated with reduced risk of obesity-related diseases such as type 2 diabetes and hypertension.

In plain English

Obese adults who used Prolibra™ whey protein while following a calorie-restricted diet for 12 weeks lost 6.1% of their body fat, which is more than the 5% reduction linked to lower risk of type 2 diabetes and hypertension.

A 6.1% reduction in body fat mass achieved by obese adults using Prolibra™ whey protein during a 12-week calorie-restricted diet exceeds the 5% threshold associated with reduced risk of obesity-related diseases such as type 2 diabetes and hypertension.

Why this might work

When a person eats this special whey protein, it releases a high amount of leucine, which tells muscle cells to build more protein and stop breaking down. At the same time, it lowers insulin and cortisol in the blood, which stops fat cells from storing more fat and starts breaking down existing fat. The calcium in the whey also helps fat cells release fat and reduces how much fat the body absorbs from food. Together, this causes more fat to be lost while keeping muscle intact.

1 study

  1. Study: A whey-protein supplement increases fat loss and spares lean muscle in obese subjects: a randomized human clinical study

    The study found that people who took this special whey protein while dieting lost 6.1% of their body fat, and the researchers say that losing more than 5% of body fat is known to lower the risk of diseases like diabetes and high blood pressure — so yes, this amount of fat loss is enough to help.
