Keto Macronutrients (aka Keto Macros)
This keto calculator will help you determine keto macronutrients to target for your unique body composition and energy needs.
When it comes to the nutritional composition of our food, macronutrients are the components that provide energy to the body.
In other words, macronutrients–aka “macros”–give us the fuel we need in the form of calories.
This fuel is used to support our activities.
In excess, the fuel is stored as energy in the form of body fat.
In a deficit, the fuel is taken from our energy stores (aka body fat).
The good old calories in, calories out concept! Energy balance applies to keto diets too.
The three macronutrient groups are carbohydrates, fat, and protein. Per gram, each macronutrient group provides different amounts of energy (calories).
- Carbohydrates yield 4 calories per gram
- Proteins yield 4 calories per gram
- Fats yield 9 calories per gram
Calories on Keto
Calculating your macros helps you to partition your planned calorie intake in a strategic way to support both ketosis and your goals.
The body’s energy needs, or total daily energy expenditure (TDEE), can be estimated using a formula to determine metabolic rate and accounting for activity levels.
The Mifflin-St. Jeor formula is used in the keto calculator for women. It has been demonstrated to be the most reasonably accurate formula for resting metabolic rate of the female body at different weights (from healthy weight to severely obese).
In other words, the formula used in the calculator will provide a fairly realistic ballpark estimation of calorie needs for women of all shapes and sizes.
Keto for Body Composition
Relying exclusively on the calories in, calories out equation can be problematic because it is not optimized for body composition or metabolism.
For example, eating adequate amounts of protein is necessary to maintain lean body mass. The tool above will calculate your macros using lean mass to guide your protein intake goal.
How Many Grams of Protein Are Needed Keto?
Protein needs on a ketogenic diet are between 0.6g and 1.0g protein per pound of lean body mass. To ensure dieters target adequate protein intake, the calculator defaults to a minimum of 0.8g/lb protein for sedentary individuals and 1.0g/lb for those who exercise.
These protein goals help to meet the increased protein requirements dieters experience due to calorie deficit, physical activity, and reliance on gluconeogenesis during nutritional ketosis. Protein intake also helps dieters increase satiety, helping to maintain a calorie deficit over time.
Getting enough protein is critical to protecting your precious, metabolically active tissue–your muscle! If your goal is to drop the extra pounds you are carrying, think fat loss rather than weight loss.
Your muscle is kind of like a calorie-burning furnace that keeps your metabolism running at top speed. If the number on your scale is dropping from muscle loss instead of fat loss, your metabolism is plummeting right along with it.
Shift your priorities and mindset:
Lean > Skinny
Body Composition > Weight
Fat Loss > Weight Loss
The last thing you want is to go on a weight-loss mission and lose lean mass in the process. The resulting lower metabolic rate can make it difficult to maintain any weight loss. Measuring body fat percentage is a more helpful metric to track progress than weight.
Keto Macronutrient Ratios for Fat Loss
Ketogenic diets are low carb, high-fat diets. As such, fat will be the primary fuel source. But these keto macronutrient ratios can be misleading to the casual dieter.
The “high fat” macronutrient can be satisfied with food on your plate or from your body. Love handles, double chins, and muffin tops can all contribute to this macronutrient group.
When weight loss is a goal, your keto macros will have a lower fat content than when maintaining weight to accommodate the necessary calorie deficit.
Fat is the most energy-dense macronutrient. Which often means the high-fat foods frequently associated with a keto diet (oils, butter, cheese, etc.) are often loaded with calories in relatively small amounts.
Measuring your dietary fats out with a digital scale or volumetric tools can be helpful to prevent accidental overeating. Just because a food is “keto” doesn’t mean you can eat unlimited amounts of it without affecting your results.
How Many Carbs on Keto?
Most keto dieters aim between 20 to 30g net carbs per day. However, the amount of carbs you can eat on a keto diet is highly individual.
Each person has their own carbohydrate tolerance that allows them to maintain ketosis. Some dieters may be able to tolerate up to 100 grams of daily total carbs without affecting nutritional ketosis, while others have more success with 50g total. When coming from whole foods, roughly half of that carb count will be fiber.
It’s important to note the difference between total carbs and net carbs. Though fiber is classified as a carbohydrate in the nutrition world, it does not directly impact ketosis or metabolism. For this reason, we do not need to avoid or limit fiber on a keto diet–which is excellent news because fiber is part of a healthy diet for a variety of reasons.
According to the World Health Organization, we should aim to get a minimum of 25g fiber per day.
In the context of keto, we can discount fiber from the total carb count and still ensure adequate fiber intake. Hence, where the term “net carbs” comes into play.
How to Calculate Carbs for Keto:
Net Carbs = Total Carbs – Fiber
Is there a minimum amount of carbs I need on keto?
Aside from adequate fiber intake, there is not a minimum required amount of carbohydrate intake for the human body. So technically, zero is the minimum.
The body has its own built-in mechanism for producing carbohydrates when needed. This process is called gluconeogenesis, which helps fuel glucose-dependent cells and maintain blood sugar when in ketosis.
The keto calculator sets the total carbs at 50g daily by default for a standard keto diet, assuming half are fiber (25g) to yield a net carb count of 25g. You can adjust the total carb values to suit your individual needs.
The calculator also provides options for other keto dieting strategies, including targeted keto (TKD) and cyclical keto (CKD). For those who opt for carb cycling, high carb days, or pre-workout carbs. These alternate dieting strategies are discussed at length in the book Keto: A Woman’s Guide.
Macronutrient Calculator: How to Calculate Macros for Keto
To manually calculate macros for keto, there is a simple process to follow taking the above considerations into mind.
- Determine Total Daily Energy Expenditure (TDEE)
- Mifflin-St. Jeor for RMR
- Appropriate Activity Multipliers
- Determine Protein Needs
- Lean Body Mass
- Activity Levels
- Set Carb Limit
- Carb Tolerance
- Fiber Goal
- Determine Amount of Dietary Fat for Energy
- Fat Loss
- Weight Maintenance
On a standard keto diet, the carb and protein macros in grams will typically remain fixed, while the fat macro is variable and based on planned body composition goals. Fat grams will be lower in a calorie deficit and higher during weight maintenance.
To illustrate, consider a woman with a 2200 calorie energy expenditure, 100-pound lean body mass, and exercises daily.
|Nutrient||20% Calorie Deficit||Weight Maintenance (No Deficit)|
|Protein||100g (400 calories)||100g (400 calories)|
|Carbs||50g (200 calories)||50g (200 calories)|
|Fat||129g (1160 calories)||178g (1600 calories)|
Calculating keto macronutrients in grams allows us to count calories simultaneously without doing any extra work. This is one of the primary reasons keto macro ratios in percentages don’t hold much meaning in the context of fat loss and body composition.
Macro Grams > Macro Percentages
You don’t drop protein and carbs lower and lower to fit some magical ketogenic ratio when you need to create a calorie deficit… you lower the fat.
For women who are looking to improve body composition and lose fat, please take this to heart: ketones are a product of fat-burning, not the cause.
