How Much Protein Should You Have in a Ketogenic Diet?

There are several factors that determine how much protein you should be consuming on a daily basis. The main two factors are your body weight and your activity level. People who are physically more active require more protein than those who don’t move around as much. A few other factors include gender and age, but those don’t matter as much as the two mentioned previously. Eating the right amount of protein is important in preserving and building muscle mass, however, too much protein can possibly put you out of ketosis. That is why out top recommended ketogenic protein powder only has 10g of protein.

General Rule of Thumb:

A very general rule is to multiply your weight by 0.6 – 1.0 and that is how much protein you should eat in one day. For example, if you weigh 180 lbs, your daily protein intake should be anywhere from 108-180 grams. This is quite a large range and you should aim to be somewhere in the middle daily. Multiplying your weight by 0.75 – 0.8 should give you a good estimate. It is important to stay in this range and not go over because you could potentially go out of ketosis. Remember to consider all other factors of you diet when calculate how much protein you are taking daily and not just the low carb protein powder.

Dr. Anthony Gustin, who is the founder of Perfect Keto, says that the number 1 mistake that people make about ketosis is not tracking the amount of protein. Eating too much protein can easily kick you out of ketosis, which defeats the entire purpose of the diet.

Final Thoughts

As we mentioned above, it is very important to stay within your limits of the amount of daily protein intake. This is why our #1 recommendation for low carb protein powder is Perfect Keto Protein Powder. Yes, it is a little pricier, BUT it does provide all of the value that you are paying for. It contains protein, collagen, and mct oil powder and is the BEST all-in-one ketogenic protein powder solution.
