Low Carb Green Protein Smoothie

Can you have greens on keto?

Green vegetables will be an important part of your diet, no matter which you choose. Keto, Whole30, low-carb and more feature greens as a centerpiece.

Vegetables do have some carbs, but they are so low you can easily maintain a diet of under 50 grams per day with a diet packed with fresh vegetables.

This low-carb green smoothie recipe is a quick and easy way to get all of those healthy greens into your meal plan.

The avocado provides a lot of healthy fats and the leafy green spinach has a serving of fiber.

Will low carb green smoothies spike my blood sugar?

Many ingredients suggested for smoothies, like fruits, have a high glycemic index. This means they will spike your blood sugar and insulin levels almost immediately. This is the exact opposite of what you are striving for on a low-carb diet.

The best way to reduce this effect is to add a mixture of protein, fiber, and fat to the smoothie. The combination of protein powder and the healthy fats in avocados makes this green smoothie recipe low carb and easy on your blood sugar.

In addition, I prefer coconut milk in my smoothies. Not only does it create the creamiest smoothie ever, but it adds more healthy fats and is very low in carbs.

Are protein smoothies good for weight loss?

Protein is absolutely necessary, whether you are trying to lose weight or not. But when you are being conscious of your eating habits, it becomes even more important.

Getting enough protein will increase your metabolism and reduce your appetite. As a result, it encourages your body to burn excess fat.

Smoothies are an easy way to add more protein to your daily diet. An extra spoonful of protein powder in this green smoothie recipe bumps up the nutrition and will leave you feeling full for a long time.

What’s good in a low carb green smoothie?

I love this healthy smoothie recipe just the way it is, but here are some other low carb ingredients you may want to add to your green protein smoothie.

  • Kale
  • Microgreens
  • Almond milk
  • Flax seed
  • Chia seed
  • Fresh or frozen berries
  • Kiwi fruit
  • Nut butter
  • Flavored extracts, such as mint, vanilla, or almond
  • Peanut butter powder

How do you keep a smoothie fresh?

The best time to consume this smoothie is directly after making it. Everything is still fresh, cold, and well combined.

However, if you want to drink it later, a protein smoothie can be stored in the refrigerator for 24 hours. Store it in an airtight container, not your blender. Fill the container to the very top to keep any air out. Otherwise, the smoothie can pick up odors from nearby foods.
