What are macros?
Macronutrients are carbs, fat, and protein. Micronutrients are vitamins and minerals.
- Carbohydrates - are simple sugars and starches. All digestible carbohydrates will raise your blood sugars and trigger an insulin demand, trigger hunger and affect mood, mental clarity, skin, inflammation to name just a few. There are no essential carbohydrates.
- Protein - supplies our body with essential amino acids which are the building blocks for muscle growth.
- Fats - provide the essential fatty acids that our body and brain needs. Choose healthy fats with minimal processing.
What is keto?
Generally, a keto diet is considered to be:
- less than 20g net carbohydrates per day
- high in healthy fats
- moderate to high protein (1.5 - 2.5 g/kg of lean body mass). In imperial units, that’s 0.7 - 1.4 g/lbs of lean body mass)
By lowering your carbs to this level, it will put your body into a metabolic state called nutritional ketosis. This state of nutritional ketosis is what allows your body to become extremely efficient at burning fat.
You become a fat burner, not a sugar burner.

How to estimate body fat
To use the macro calculator, you need to estimate your body fat. These pictures are easy to use so you can estimate your %.
Why is body shape important?
Should you restrict your carbs even if you are slim? Your body composition, where you store your fat, is a crucial factor.
Those who carry excess weight mainly around the tummy are more likely to be insulin resistant. Apple shape (band of tummy fat) should be more aware of their carb intake compared with pear-shaped (mainly bottom-heavy).
So if you have always had skinny legs but notice a tummy starting to appear, then watch your carbs as it is this visceral (tummy) fat that is more dangerous to your internal organs.
How to set your own carb/fat/protein goals
The keto calculator will help you set your carb limits, your protein targets and your fat limits. You might also want to look at the keto food pyramid so you have an idea of how to build your meals and snacks.
- Carbs - set your limit. 20g is keto, 50g is low-carb, 100g is moderate low-carb
- Protein - is a target. The amount required by each individual will vary depending on your level of activity
- Fat - is a limit. It is a myth that a keto diet should be based on high excessive amounts of fat. The calculator will show you the MAXIMUM fat each day.
How much protein is too much?
Too little protein and your appetite will not be stable, too much and this may create a weight-loss stall. But for most, increasing protein allows them to lower their carbs and fat.
Protein is satiating, protein is required for our essential amino acids. Choose quality protein sources.
