How Does Our PrimaForce KetoShake Stack Up Against Low-Cal Competitors?

 

Consumption of convenience foods has been on the rise for decades1, with more and more Americans embracing an alternative to hours spent in the kitchen. Sure, everybody loves good home-cooked meals, but simply can’t fit them into their schedules every day. Instead, restaurants and manufacturers stepped in to offer drive-thrus, heat-and-eat meals, and other grab-and-go fare. It didn’t take long for these quick eats to be implicated as major contributors to society’s growing waistlines and climbing rates of metabolic disease. With pressure from consumers’ increasing concern (obsession?) with health, food companies turned their attention to making more nutritious products that were still quick and tasty.

Enter, the “healthy shake.”

Whether it comes in a carton, a can, or as a powder that you blend into liquid, meal replacement drinks (MRP) have evolved as a staple in the health and wellness sphere. Not only are these shakes a market success, but they also appear to be pretty effective aids to certain health goals. A meta-analysis of six different studies found that individuals swapping out one meal a day with a liquid MRP achieved and maintained health improvements better than those following a calorically-equivalent regular-food diet.2 Simply put, MRPs help us stick to our nutrition goals by offering a ready-to-consume food when we may otherwise grab a bag of chips, candy bar, or skip eating altogether. However, a glaring caveat exists when considering the contents and quality of various shakes – not all MRPs are created equal.

Problems arise when simply comparing a product’s calorie count, or falling victim to common macronutrient myths (i.e. the fat-free craze of the ’80s). What’s actually in that MRP shake makes a huge difference. The energy you’re getting, or not getting, from a bar or a shake ultimately boils down to the amount of carbs, protein, and fat contained inside. We can turn any of those three macronutrients into usable biochemical fuel, known as ATP. However, the body’s physiological response to each macronutrient is very different, and this has important implications for how satiated, energized and focused we feel after consuming a meal or a snack.3

Sure, the quality of ingredients definitely matters as well, which is why PrimaForce KetoShakes contain well-sourced oils, grass-fed whey, and no artificial sweeteners, coloring, or flavors. But even when simply looking through a metabolic lens, one can see how the macro profile of PrimaForce KetoShakes stack up against competitors to help you fuel your best.

The conventional “low-cal” shake

The typical American approach to health and wellness has long looked to calories as the sole driver of weight change. As a result, many companies push meal-replacements with low-calorie claims, but little regard for the nutritional quality of the calories they provide. A majority of these MRPs are packed with refined carbohydrates, thickeners, and artificial sweeteners, but barely any fat or protein to satisfy hunger and provide a balanced meal. Think about how many times you’ve chugged that “healthy shake” just to end up starving an hour later. It was most likely high in carbs and nothing else. Beyond anecdotal evidence, scientific research indicates that fat and protein tend to have a more satiating effect than carbohydrates.4

Furthermore, a more satisfying shake can help you actually stick to your health and wellness goals in the long term. Researchers have also observed higher drop-out rates in study groups forced to restrict fat intake compared to those on a prescribed low-carb, ketogenic diet.5

At a judicious 160 calories, PrimaForce KetoShakes fall right in step with a lot of the products you’d find on supermarket shelves or in nutritional supplement stores. But unlike others, PrimaForce KetoShakes are meticulously formulated with 13 grams of fat, 7 grams of protein, and 4 net carbs to keep you feeling energized and to stave off hunger until your next meal. No empty calories here.
