What did GNC Study?
At GNC, research informs everything we do – so you get the real results you’re looking for. What most people don’t know is that GNC has invested in clinical research on several of its top-selling products to demonstrate their effectiveness.
In this article, we’ll do a deep dive into one of GNC’s clinical studies where a ready-to-drink meal replacement was put to the test. Total Lean® Lean Shake™ 25 Ready-To-Drink contains 25 g of protein, plus more than 20 essential vitamins and minerals you would find in a typical meal! Passionate about the health and wellness of their customers, GNC’s researchers were interested in learning the impact their meal replacement formula would have on body weight, when used as part of a weight loss journey.
What Was The Objective of The Study?
The primary goal of this study was to determine the effectiveness of GNC’s Total Lean® Lean Shake™ 25 formula on body weight. Secondary objectives of the study were to evaluate the effects on body composition, including body fat, waist and hip circumference, and blood lipid levels. Researchers believed their meal replacement formula would aid in the loss of body fat while preserving lean muscle.
Who Were The Study Participants?
109 overweight and obese males and females between 21 and 55 years of age. Volunteers had a Body Mass Index (BMI) of no less than 25 and no greater than 39.9.
What Was The Study Design?
GNC chose a randomized, controlled, parallel group study. Volunteers in both groups followed a 1500 calorie per day meal plan and were randomly assigned to one of two groups:
- Group 1: Received two Total Lean® Lean Shake™ 25 meal replacements daily in place of breakfast and lunch. They were encouraged to consume a healthy dinner that fit into their meal plan.
- Group 2: Did not receive a meal replacement
Participants were instructed to walk for a minimum of 30 minutes at least three times per week. Vital signs, height, weight, body composition, blood chemistry and lipid profiles were collected at six points throughout the duration of the 12-week study.
What were the results of the study?
Researchers found that over a period of 12 weeks, the group receiving the Total Lean Shake® formula lost nearly 2 times the weight (-7.6 lbs) when compared to the group following the 1500 calorie diet alone (-3.9 lbs). The meal replacement group also saw a larger reduction in body mass index (-1.2 km/m2) vs diet alone (0.6 km/m2).
What does this mean?
As revolutionaries in the field, GNC put it’s ready-to-drink meal replacement formula to the test, something competitors rarely do. The results of this study mean that not only is Lean Shake 25TM RTD delicious and packed with high quality protein, but when used as part of healthy diet and exercise regimen, it can help you lose more weight than just trying to cut calories alone.
