How the MET-Rx Original Meal Replacement Changed the Protein Game

It’s not often that a product comes along that is versatile enough to support a wide range of individual goals: including for those looking to just take off a few pounds and get leaner, to the athlete living in the weight-room looking to pack on muscle and strength, or anyone simply looking for a high quality nutrition drink for breakfast or in between meals. But of all the great products MET-Rx has to offer, nothing else quite fits the bill like our Original Meal Replacement. 

The History of the Original Meal Replacement

Not many protein products on the market can say they’ve been around long enough to have a history. But when it comes to the “Original” Meal Replacement (OMR), this truly is the product that started it all.  Originally developed in the 90’s, the “White Box” meal replacement (as it’s also referred to) was a game changer when it came to high protein nutrition. White Box was first developed by a Physician looking to provide a product to his patients that could meet their high metabolic needs for protein. Early studies in the 90’s demonstrated that White Box was an effective strategy to maintain lean muscle in those with elevated requirements1,2.

As the study of protein nutrition evolved, it become clear that almost anyone looking to get into shape can benefit from a high protein nutrition plan.  Gone are the days when high-carbohydrate, processed foods like pasta and bread were hailed as the cornerstones of healthy diets. In fact, a review article by the Journal of the International Society of Sports Nutrition credited a high protein intake to being the common theme that leads to success on certain plans including low-carb diets3.

The OMR Protein Difference

Our formula revolutionized the concept that not all proteins are the same, and can have synergistic benefits when combined together in precise ratios. While the formula has been updated over the years, White Box still contains both fast and slow acting proteins in a blend we call Metamyosyn. Whey protein is considered a “fast” protein because it digests quickly to provide your muscles with important amino acids right when you need them. Casein digests much slower over the course of several hours. This helps to not only keep you feeling full but also supplies muscles with a steady stream of the nutrients they need to recover from exercise and get stronger. The main protein used in OMR is milk protein, which is naturally comprised of both whey and casein.

When to Take

If you are starting to suffer from bar fatigue and looking for a creamy beverage alternative, then Original Meal Replacement is a perfect go-to.  While the OMR is less calories than our Big 100 Bars, you can mix with nutritious ingredients such as almond butter or low fat milk to create a more satisfying meal replacement for breakfast or lunch that still packs the same nutrient-dense punch. Or if you are looking for something lighter than the bars – simply mix with water and low calorie berries for a healthy treat. 

OMR also makes the perfect post-exercise recovery beverage. Whey protein will help your muscles start recovering right away while the slower digesting proteins provide extended support well after your workout is finished. In fact, a recent study found that after hard training involving upper and lower body weight-lifting, consuming 40 grams of protein was more effective in stimulating muscle building than 20g4. While the Original Meal Replacement is just a tad under 40g protein, simply adding some nut butters or milk to your blender will make up the difference.

And remember you don’t have to be lifting heavy weights to reap the benefits of the Original Meal Replacement. Quality protein combined with the right balance of carbohydrates, plus essential vitamins and minerals, is always a good choice for any active lifestyle.
