BMI: Calculate your Body Mass Index
BMI is an index that relates to a person's height and weight and serves as an indicator of that person's body weight.

BMI of less than 18.5
Normal weight
BMI is 18.5 to 24.9
Overweight
BMI is 25 to 29.9
Obese
BMI is 30 or more
Basal Metabolic Rate Calculator
Calculate your Basal Metabolic Rate or BMR also called Resting Metabolic Rate or RMR, with our online calculator tool. Learn how to use it as a starting point for your weight loss program.
Go to the calculator:
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
Our calculator will help you work out the basic macros for your Ketogenic Diet.
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 make up 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 intake is the key to all weight-loss diets). And then based on the recommended protein requirements based on your level of activity and the mass of carbohydrates that you plan to ingest daily, it defines the mix of protein, carbs, and fats for your diet.

You can improve your life quality by shedding a few pounds.
