If you're a serious bodybuilder, you know that protein is an essential dietary component of your efforts to trim excess fat. Protein, after all, supports muscle tissue, which, in turn, burns fat as energy. And protein intake is much less likely, metabolically speaking, to be stored as fat than carb intake. When it comes to refining and maximizing body composition, protein is the way to go.

Here's the conundrum, however. As a serious bodybuilder, you're probably already consuming plenty of protein already. Simply consuming more protein probably isn't going to help you shed those last few pounds of stubborn excess body fat. Taking a higher-quality whey protein isolate (with its zero or extremely low carb content) instead of a lower-quality whey concentrate will certainly help. Hopefully though, you're already taking a superior, precision-targeted, growth-factor-rich protein like the industry's gold standard, NytroWhey Ultra Elite.

But when excess fat loss is the order of the day, it's time to raise your game even further. Fortunately, cutting-edge protein science has you covered with a new kind of unique fat-loss protein. Vectron by ProSource contains an elite fractionated protein matrix called Prolibra, a specialized bioactive peptide technology (along with a special mineral complex) designed specifically to target essential mechanisms of body composition and improve your ratio of lean muscle mass to fat. Indeed, clinical documentation supporting this capacity is quite exciting. Before we get there, though, let's talk about protein and fat loss.

Protein and Fat Loss
Research has shown higher protein intakes can promote weight loss with a greater percentage of the lost weight coming from body fat. (1-3). Typically this favorable change in body composition following a high protein diet stems from two occurrences:

1) The consumption of protein results in the greatest thermogenic effect compared to the other macronutrients; essentially meaning it takes more energy (burns more calories) to digest protein compared to fats and carbs.

2) Consuming protein aids in the maintenance of lean muscle mass, which is an active tissue and requires energy to maintain, as it is always repairing and remodeling itself in a state of constant turnover.  

Therefore a high protein diet combined with a resistance training program can oftentimes be a successful strategy for weight loss as they both promote increases in lean muscle mass.

How Much Protein Is Enough?
In order to reap the benefits of a high protein diet you must obviously eat more protein! However, it doesn't necessarily mean that you should consume an extra 20 chicken breasts throughout the day hoping to lose body fat. What it means, is that a higher proportion (or approximately 25-40%) of your daily calories should be coming from protein. The US recommended daily allowance (RDA) is 0.8 grams per kilogram per day (g/kg/d), however research has indicated that active individuals may have higher protein needs, somewhere in the ballpark of 1.2 to 2.0 g/kg/d (5,6). So if you are a 220 lb. active individual, your protein needs would be somewhere in the range of 120 to 200 grams of high-quality protein per day.  

Vectron is a Powerful Fat-Loss Tool
Now let's take it one step further and look at what happens when research scientists combine a superior quality protein with an advanced formula that specifically targets the improvement of the ratio of lean mass to fat. ProSource has combined the benefits of a protein supplement with cutting edge technology in a new product: Vectron.  Vectron isn't just any ordinary protein supplement as it contains a unique fractionated protein complex called Prolibra which is specifically designed to positively alter one's body composition with the help of a clinically proven fat-loss, muscle-supporting protein matrix.

Prolibra is an independently tested whey-derived ingredient designed to enhance the fat burning effects of a protein supplement while maximizing gains in lean body mass. An independently conducted university study found a 5.81% reduction in body fat mass after supplementing with Prolibra compared to only a 2.29% reduction in the placebo group. A similar study found a 2x greater increase in lean muscle mass with 79% of the weight loss coming from body fat compared to the control group with only 51% of the weight lost coming from body fat after 12 weeks of whey protein (Prolibra) supplementation (1).  

Results of this study also suggested that Prolibra consumption may help reduce the glycemic response after a meal which can further enhance fat loss over time.  Specifically, the study indicated that consumption of Prolibra, as found in Vectron, resulted in a reduction of 37.8 glycemic index (GI) units which can help control appetite, maintain energy levels and improve insulin sensitivity; not to mention keep you in fat burning mode longer!

But Won't Extra Protein
Just Turn Into Fat?

To the general population, a protein intake of 2.0 g/kg/d may sound high, however this and even higher intakes are common practice for strength and power athletes, specifically bodybuilders. Some people have the assumption that extra protein will just get converted into fat, leading to undesirable changes in body composition. However, research suggests that even a high-calorie diet with a protein intake as high as 4.4 g/kg/d for 8 weeks (approximately 440 grams of protein per day for a 220 lb. individual!) did not result in any significant changes in body composition compared to a control group consuming 1.8 g/kg/d (7).  The 4.4 g/kg/d of protein came about to be approximately 45% of their total caloric intake for the day.

A similar study had subjects consume a high calorie diet. However, in this case the additional calories came from high-carbohydrate, sugary foods which led to an increase in body fat (8). The moral of the story is that if you are going to be consuming excess calories, select high protein / low-carbohydrate foods, and you will be less likely to experience any increases in body fat.

A high protein diet can not only help add pounds of lean muscle during a mass gaining phase, it can also help you maintain your hard earned muscle during a cutting phase or even promote favorable changes in body composition over time.  Maintaining lean muscle during weight loss will help you balance your calorie expenditure and prevent a drop in metabolic rate which can help keep those pounds off and prevent yo-yo dieting.  

An even better strategy when targeting fat loss is to add a specialized fat-loss protein like Vectron to your regimen in order to support efforts to lose body fat while maintaining lean muscle mass. Vectron is an invaluable asset for optimal changes in body composition!
