What is Resting Metabolic Rate or RMR?

Basal metabolic rate definition

RMR is the rate at which your body burns energy when it is resting (its only activities under these circumstances is breathing, blood circulation and brain activity).

It comprises the energy used by your body to keep your body alive at rest. This covers the cellular activity (respiration, normal functioning) and maintaining body temperature within its correct ranges.

Keto Macros Calculator

What are macros in Keto dieting?

A Ketogenic Diet is a very low carbohydrate, moderate protein and high fat diet. It will also include a caloric deficit if your goal is to lose weight.

The exact mix of protein, fats and carbs plus your daily caloric intake are the "macros" of your diet.

How does this Keto calculator work?

The calculator takes your gender, height, weight and age to calculate how much energy your body requires in a resting state, then it adds your level of physical activity to define your energy requirements.

It subtracts the energy deficit you want to adopt (less energy energy intake is the key of all weight loss diets). And then based on the recommended protein requirements based on your level of activity and the amount of carbohydrates that you plan to ingest daily, it defines the mix of protein, carbs and fats for your diet.
