Our nutrition and macronutrient ratio calculator makes working out your perfect diet plan much easier!

Knowing what calories and macros you should be eating lets you concentrate on the more important task of hitting those recommended nutrition targets and getting that dream body!

Once you’re into the calculator, simply fill in the form and it will calculate your caloric intake, protein requirements and macronutrient ratios, which will be emailed to you for safekeeping. These values should provide you with a great starting point for your nutrition plan!

Before You Start

Before you can use the nutrition calculator you need to work out two things:

  • Your Body Type
  • Your Body Fat Percentage

These both have a big impact on your nutrition targets, so it’s important you spent a couple of minutes working these out if you’re serious about getting head-turning results.

Work Out Your Body Fat Percentage

The easiest way to work out your body fat percentage is to estimate it using the diagrams below — do the best you can and be realistic.

Avoid using bathroom scales that tell you your body fat percentage – these can be wildly inaccurate and estimating by looking is almost always better!

If you are lucky enough to have access to a body composition scanner then that’s the best and most accurate method to use. However, these are expensive and usually only available to scientists, students and top athletes.Nutrition Calculator - Male and Female Body Fat Percentage Diagram

Work Out Your Body Type

We are all naturally different and have our individual strengths and weaknesses.

This calculator accounts for variation between individuals and doesn’t just lump you into a standard diet plan like most do (which is a MASSIVE mistake!). The key thing to remember is that whatever your body type, you can see amazing results with the right nutrition plan!
