10 Best Keto Protein Powder Reviews

Top 10 Keto Protein Powders

Optimum Nutrition’s Platinum Hydro Whey is a premium source of protein that keeps you carb count down while delivering pure amino acids that are broken down to get into the muscles faster. The thing that makes Platinum so special is that the proteins have been hydrolyzed. That means that they’re broken down into their constituent parts. This dramatically speeds up the absorption into the bloodstream and delivery to the muscle cells.

Most protein powders will give you a blend of protein types that feature a bit of the more expensive proteins and a lot of the less expensive ones. But with Platinum, 100 percent of the protein is hydrolyzed. That makes the product a little more expensive than some of the competition, but it also gives it the very best quality.

Hydro whey protein is the most digestible form of whey protein for human consumption. It is partially pre-digested for better absorption, with the protein molecules being split into smaller compounds called peptides.

With Platinum, you get just two grams of carbs per serve, along with 30 grams of protein. That makes this a superior protein choice for followers of the keto lifestyle. It’s noticeably more expensive than lesser quality offerings, but if you’re after the best keto protein powder, you need look no further!

Naked Whey have staked out a position as a supplier of protein powder that comes from only 100 percent grass fed cows. The milk that is used is also non-GMO and denatured. That ticks a lot of boxes built it does not lead to a top quality protein for muscle building. The type of protein here is what protein concentrate – it is miles away from the likes of the hydrolyzed whey used in Optimum Nutrition Platinum Hydro Whey.

Naked Whey is a low carb protein powder with just 3 grams per serving. It’s also got a low calorie count at just 120 calories which is great if your trying to strip off body fat. The protein is kept as pure as possible, very easy to digest so that it can be utilized immediately after your workout for muscle growth and repair. However, because the protein is whey concentrate, the fat lactose and cholesterol has not been removed. This gives it a relatively low protein purity score. It also means that people who are lactose intolerant are going to have problems with this powder.

This powder will keep you in keto and is probably going to be just fine if you’re not lactose intolerant.

  • Only uses grass fed cows
  • Low carb
  • Low calorie
  • Only uses whey concentrate
  • No good is lactose intolerant
  • Expensive

Optimum Nutrition 100% Whey is a blend of three types of protein to provide fast, slow and medium acting amino acid release.

Importance of Protein Powder in Ketogenic Diet

Protein is the building block of muscle. So, if you are intent on either building or maintaining a decent amount of muscle on your body, you need to taking in quality protein. If you work out, you need it even more. This is as true when you’re doing keto as it is at any other time.

You especially need protein after your workout, when you muscles have been broken down from your training. The protein in your shake is the fastest way to get amino acids into the muscle fiber so that it can rebuild and re-strengthen.

Benefits of Protein Powder for Weight Loss

keto diet weight lossThere are two key benefits of protein when it comes to weight loss. The first is that protein is the most thermogenic of the macronutrients. That means that it takes more energy in the form of calories to digest protein than it does for carbs and fats.

The other benefit is that protein fills you up more than carbs and fats. After you’ve had a protein meal you won’t feel the need to snack between meals. That will help you to keep your daily calorie count down.

When and How to take Protein Powder when on a Keto Diet

When on a keto diet, you should limit your protein powder intake to your post workout recovery time. This is the time when your body is craving amino acids to start the repair and recovery process.

Take a single scoop of powder with water. Don’t add fruit or milk or you’ll be adding extra carbs to the mix.
