However, enjoying and using them well requires know-how and experimentation. Let’s go over some of the ways you can use low-carb proteins to enhance your health and diet:
1. Choose a Powder That Matches Your Dietary Needs and Goals
If you are following a keto diet, avoiding plant-based proteins is best. Why? They contain higher net carbs than animal-based proteins. One way you can go about it is by looking for supplements with ingredients that support ketosis, like MCT oil.

2. Experiment With Recipes and Flavors and Choose What You Like
Most of the time, supplements have a bland or chalky taste, but low-carb sweeteners or fruits can help improve the taste. For example, you can make a vanilla blend smoothie by mixing the low-carb vanilla powder with spinach, frozen berries, and unsweetened almond milk.
3. Time Your Protein Intake According to Activity Level
When you’re between meals or on the go, you can use low-carb protein powder as a post-workout or even pre-workout supplement. For example, a protein shake before or after a workout can fuel your muscles and speed recovery.
Low-carb protein supplements can add versatility and convenience to your diet without a lot of sugar or carbs. They can come in handy in achieving your nutritional needs, aiding fitness goals, and satisfying your taste buds.
