Keto Calculator

So,what is a Keto Calculator?

So, you are thinking about getting started on the ketogenic diet? If so, then one of the first steps is to use this Keto Calculator to determine the macros that are specific to your body and your goals. This is a highly individualized macro calculator and for that reason the results will be tailored to you and only you!

Before we begin, what is a macro?

To begin with, macronutrients (or macros) are very important to the ketogenic diet. Macronutrients are fats, protein, and carbohydrates, and they are indeed the major building blocks of the foods we eat. In short, the ketogenic diet all boils down to eating foods that have the right macronutrient composition.

Another key point is that all three of these nutrients have different effects on ketosis from their digestion and have consequent effects on blood glucose and hormones.

  • Fats are 90% ketogenic and 10% anti-ketogenic. This is because of the small amount of glucose that is released in the conversion of triglycerides.
  • Proteins are typically ranked at 45% ketogenic and 58% anti-ketogenic. This is due to the fact insulin levels rise from over half of the ingested protein being converted to glucose.
  • Carbohydrates are of course 100% anti-ketogenic. Reason being, they raise both blood glucose and insulin.

So, how do you calculate your macros?

To begin with, cutting carbs and upping fats is the quickest way to induce ketosis. Because of that, a good starting point is a limit of 5% of your daily intake to carbs which is equal to 20 grams per day. Overall, most people do just fine counting net grams of carbs (Total Carbs – Dietary Fiber = Net Carbs) and staying under 50 total grams of carbs per day.

With that said, it is important to note that those who are insulin-resistant, Type-2 Diabetic (unless they are taking insulin), and/or have metabolic damage from years of dieting and/or eating disorders (a slow metabolism) will have a lower carbohydrate tolerance and should stay at 20 TOTAL grams of carbs per day. Therefore, carbs will make up about 5% of their daily intake.

Next, you need to determine your lean body mass and set protein goals accordingly. With this in mind, protein should be about 20-25% of their daily intake, typically between 0.6-0.8 grams of protein per pound of lean body weight. However, anything below 0.6 grams can cause a loss in muscle, and we do not want that!

Finally, and most important, is fats. Specifically, we want the total daily caloric intake to be about 70-80% fat.

As can be seen, macronutrient goals vary greatly from person to person. So, it takes a bit of experimenting to get it exactly right, and the body’s needs change over time and at different seasons of life.

What do you need to know prior to using this Keto Calculator?

To begin with, you need to know you current percentage of body fat. Note, that he Keto Calculator is defaulted to 25% body fat, so specifically be sure to change that. This is because the Keto Calculator uses your lean weight (total weight minus body fat) to calculate your macronutrients. You can use a smart scale or you can also use a body fat caliper to get this percentage. Or, instead, you can just use this handy online tool to calculate it:

Knowing macronutrient numbers (protein, fats, carbs) and your daily calories is important for your success in weight loss goals! Generally, you want to keep below 20 grams of net carbs to stay in ketosis, but how about your fat and protein? For this reason, you can use this Keto Calculator to find out exactly what your daily calorie intake and macronutrient breakdown should be.

Undoubtedly, keto is not one size fits all. Specifically, take the time to dial in your personal macros in a way that benefits you the most. Basically, carbs are a daily max, protein is a goal to reach, and fat is to satisfy. Of course, the macro calculation above is meant to be a good starting place. However, optimal macros will likely vary based on your own trial and error.
