Principle of FETT-FREI Program

The Fett-Frei program is based on the principal that it is not important how much you weigh, but rather on the composition of your body mass. For example, an 185 cm man weighing 100kg with a high percentage of muscle and lower percentage of fat, will look leaner and be healthier than a woman with “normal” measurements but with less muscle and a higher proportion of fat. On the other hand, if she can have the same weight but a high percentage of muscle and lower percentage of fat mass, she can be perfectly healthy.

 

What is a normal weight?

The BMI (Body Mass Index) is a measurement of a person’s body weight in relation to their height. Since 1832, a person’s BMI number has been used by medical professionals to determine a person’s Adipose classification. Currently, the WHO standard for a normal Adipose classification is between 18.5 and 24.9, although 20 years ago a measure between 18 to 22 was considered a normal rating.

Body mass index is calculated as:
BMI = m(kg)/l2 (m2)

m is the mass of a person in kilograms
l is the person’s height in meters.

For example:
if a man is 80kg and is 185 cm tall,
his BMI = 80kg/(1.85m x 1.85m) = 23.4;

if a woman is 65kg and 170cm tall,
her BMI = 65kg/(1.7m x 1.7m) = 22

The BMI is only an approximate value, because it does not consider either a person’s build or gender, nor the composition of the body measurements between fat and muscular tissue. BMI also does not describe a person’s appearance.

If we look at the picture, we can see that both people have the same BMI (same weight and same height) even though they look completely different. Hence, BMI cannot tell us how a person looks like.

BMI does not describe a person’s appearance.

 

 

 

 

Measurement of the waist and hip (Hip/Waist Ratio)

The waist to hip ratio helps us understand where a person’s fat deposits sit. This can be calculated by: circumference of waist/circumference of hips, where the waist is measured at navel height and the hips measured at the widest point. Ideally, this ratio should be 1.0 for men and 0.85 for women. Belly-stressed predominance (apple type) indicates a much higher risk of heart-related illnesses, as fat deposits in the belly reduce space in the body and stress the internal organs.

BIA Measurement Method (Bio-impedance Analysis)

Nowadays all modern nutritional methods do not describe your body composition and health condition based on your body weight, but by analysing the structure and composition of  body tissues. Changes in body weight can be due to changes in water, muscle or fat masses. One of the most popular methods in calculating percentage of fat tissue on a body is called the BIA method.

The whole procedure is simple, painless and safe. It has already been used for many years in clinical medicine: endocrinology (metabolic syndrome, diabetes), nutrition, geriatrics, sports medicine, and others. BIA measurement lasts 5 min and gives you the complete picture of your body composition: quantity of water, muscle mass, fat mass, and most importantly it can tell the quality of your cells – whether they are nutrient enough.
