Buying Guide: Best Keto Protein Powder
With the rise of the ketogenic and Paleo diets, protein powder has become a staple in many people’s diets. It can be used in smoothies and shakes or simply added to water for an easy protein boost. These days, there are many different types of protein powder on the market today, and not all are created equal. So how do you find the right supplements for your dietary needs? How can you be sure that your protein powder will not kick you out of ketosis? Don’t worry! In this handy buying guide, we’ll discuss what to look for in a keto protein powder, so you can make an informed choice.
How To Choose Quality Keto Protein Powder?
Ingredients
As with any supplement, it’s important to choose a high-quality product that contains ingredients that are both healthy and effective. Before settling on a product, scan for artificial sweeteners, preservatives, additives, or other potentially unnecessary ingredients that are not in line with your ketogenic diet goals. Look for powders made from quality, natural sources such as grass-fed beef and free-range eggs for the best results!
Protein content
The amount and quality of protein in the powder should be one of your top considerations when purchasing. Be sure to check the label and select a product that contains a high amount of quality protein (ideally, at least 15-20 grams per serving). This will ensure you are getting enough protein to meet your needs and maintain your ketogenic diet.
Carb status
To stay within ketosis, you must go with a product that keeps net carbs lower than 5 grams per serving. Most keto-friendly powders contain minimal amounts of carbs, but some may be higher than others, so check the nutrition label before purchasing.
Sweeteners
You should also check is whether your keto protein powder contains any sweeteners. Most low-carb diets recommend avoiding artificial sweeteners like sucralose or acesulfame potassium because they can be harmful to your health. If you’re looking for something to add just a hint of sweetness without changing the flavor of your shake, try monk fruit extract or xylitol; both are great for anyone with sensitivities to other artificial sweeteners, and they won’t mess up your blood sugar levels. If you want something more intense, there’s always stevia that can add a nice flavor to your otherwise bland drink.
Flavor
While most people don’t mind eating bland food while they’re on a keto diet, others don’t like it at all. Most unflavored protein powders work great as a base to add your favorite flavors, but if you’re after something with a bit more flavor kick, opt for one that comes in coconut cream pie, vanilla, or chocolate flavor.
Taste
The taste of your protein powder is another important factor to consider when choosing one. Most people prefer powders that have a mild, neutral flavor that blends well with other ingredients in their smoothies or shakes. You also want to avoid ones that are overly sweet or bitter, as these can ruin the taste of your drink.
