What is the Best Keto Protein Powder?

While on the keto diet, there are specific dietary restrictions put in place to encourage ketosis. Ketosis is a metabolic state where the body burns fat rather than glucose for energy. Keto dieters examine net carbs and total carbohydrate content in foods and must limit consumption to encourage the body to enter the state of ketosis to encourage benefits like fat loss. 

Incorporating a low-carb protein powder, such as a plant-based protein or other protein powders like whey, is helpful in encouraging the maintenance of lean muscle mass and fat loss during body recomposition efforts. 

Final Thoughts

If you’re following the keto diet and looking for low-carb protein powders to fuel your health and fitness journey, you’ve come to the right place!

Throughout this article, we’ve listed the best keto protein powder supplements. We’ve analyzed the quality of ingredients, flavor, taste, and pricing of each product, so you don’t need to. Each product on this list empowers intricate formulas and nutrient-rich ingredients designed to empower the utmost benefits in muscle recovery, maintenance, and growth while empowering progress in fat loss journeys with low-carb, high-protein powered supplements. 

FAQs

Can I drink a protein shake while in ketosis?

Consuming protein supplements like powder is entirely acceptable while in ketosis. It is vital to meet your daily protein needs to fuel your body and maintain lean body mass properly. Many individuals choose to enter a keto diet to encourage fat loss, so incorporating an effective combination of resistance training and protein in one’s diet can appropriately promote the maintenance of lean muscle mass during body recomposition efforts. 

Can too much protein ruin ketosis?

While on a low-carb diet like the keto, protein needs must be met, but they may need to be adjusted compared to a non-keto diet. To explain better, protein consumption must be moderate while on the keto diet, as too much can break or prevent ketosis. Many popular ketogenic resources recommend standard keto dieters consume 70-80% fat, 10-20% protein, and 5-10% carbohydrates. 

Does MCT powder help ketosis?

Consumption of healthy fats while on the keto diet is vital as this is the main contributor of calories in the diet, making up 70-80% of a standard keto diet. MCT powder or oil can be a healthy contributor to the keto diet as it provides a fat-based energy source while on a low-carb diet.
