How to Measure Body Fat Percentage

Learn how to measure body fat percentage and why measuring fat loss is significantly more important than weight loss to overall health.

How to Measure Body Fat Percentage

Fat Loss versus weight loss

The fitness and nutrition industry has detrimentally affected the health and wellness of society over the years by the constant focus on weight loss instead of fat loss and irresponsibly neglecting to clarify that they are not one and the same.

Your overall weight, or body composition, is made up of total body fat and lean body mass (everything other than fat).

Body Composition (Total Weight) = Body Fat + Lean Body Mass

As muscle weighs more than fat, someone could be leaning up by replacing visceral, disease-inducing fat with healthy, calorie-burning muscle mass and weigh the same as they did before. #ditchthescale

Someone could lose calorie-burning, structure-supporting, disease-preventing lean muscle mass and lose weight. #ditchthescale

A woman could weigh “just right” and rock washboard abs but struggle with hormonal imbalances because she doesn’t have enough body fat. #ditchthescale

A muscular man could be at a healthy body fat percentage, but due to a number on the scale be considered overweight. #ditchthescale

Here is a real life example of the absurdity of a number on the scale as it relates to wellness or overall health.

In case you are new around here, that is Zach. [The big one. Not the little one.]

My man.

Who is clearly not “overweight”.

The point is this.

Weight, or body composition, is multi-factorial, and fat loss is very poorly reflected by a number on the scale.

Sooooooooo. . . .

. . . around these parts we are all about fat loss as it relates to body composition change which includes lean body mass or muscle.

Body Composition (Total Weight) = Body Fat + Lean Body Mass

Calculating lean body mass is sometimes necessary for medicine, but more often than not it is used by bodybuilders or those specifically interested in muscle hypertrophy as this number can be used to isolate total muscle mass.

Generally when we talk about body composition we are talking about body fat percentage.

HOW TO MEASURE BODY FAT PERCENTAGE

Measuring Body fat percentage

This begs the question that if body fat percentage is more reflective of our overall health than a number on the scale, then how do we measure our body fat percentage?

There are many different ways, but the simplest is to use a body fat caliper. On Amazon HERE.

There are two methods – a 3 point site method or a 7 point site method. The 3 point method is the easiest.

Male measurement sites:

• Chest: diagonal fold half the distance between anterior axillary line and the nipple.
• Abdominal: vertical fold 2cm to the right of the navel.
• Thigh: midpoint of the anterior side of the upper leg between the patella and top of thigh.

Female measurement sites:

• Tricep: vertical fold at the midpoint of the posterior side of tricep between shoulder and elbow with arm relaxed at the side.
• Suprailiac: diagonal fold parallel and superior to the iliac crest.
• Thigh: midpoint of the anterior side of the upper leg between the patella and top of the thigh.

The video above gives an excellent demonstration of how to measure all 7 sites, but just watch how to measure the 3 sites and then you can enter your measurements into this calculator.

Once you have your body fat percentage find yourself on my body composition spectrum below.

body composition spectrum

Let me be very clear that this spectrum is not a gospel truth, but more so it is my assessment of the habits generally true of people at these points on the spectrum based on 15 years of medicine and a lifelong pursuit of wellness.

Stick around because we are going to break down this chart as it relates to weight loss, yoyo dieting, the coveted 6-pack, sustainable fat loss, and ultimately, the pursuit of living well.
