The Charles Poliquin BioSignature Modulation Method

Sam O'Sullivan has recently become one of a selected Health professionals in Wales to become a Charles Poliquin Biosignature Practitioner.

Biotyping is gaining popularity amongst healthcare professionals, personal trainers and Nutritional Therapists.Its a principle whereby nutrition recommendations are individualised to suit metabolism and biochemical individuality to help boost Fat loss and improve health.

Charles Poliquin developed his form of biotyping whilst working with athletes, gaining data from blood, urine and saliva tests. Ift focuses on specific body fat reduction through hormone balance. Poliquin believes that fat accumulates in specific body areas because certain hormones are too high, too low or just out of balance and this belief is based on 20 years of his own data. There is research to suggest that higher body fat levels disrupt hormones causing diseases such as diabetes, heart disease and cancer and there is also evidence to support assertions of hormones causing regional fat distribution. 

The BioSignature Method is designed to offer a new alternative to fat loss, offering faster fat loss and scientific spot reduction.

The Method relates to the relationship between body fat stores and hormonal profiles, and the methodology to improve site specific body composition. The BioSignature method brings together the best principles of naturopathy, functional medicine and exercise science to bring about a revolutionary new method of achieving fat loss and optimal health.

How Does The BioSignature Method Work?

There are 12 major body fat sites that can be quickly and accurately tested by a pair of quality skin calipers and a qualified technician. These sites include the cheek, chin, pectoral region, triceps, umbilical, supra iliac, subscapular, mid axillary, quadriceps, hamstrings, knee and calf. Although there are many other methods to test body fat, such as underwater weighing and electrical impedance, Poliquin believes that body fat testing with skin calipers is the best method to be used for Biosignature Modulation because it can determine precisely the amount of fat in each of the major fat-testing sites where other testing methods only tell you your percent body fat.

Hormones BioSignature Looks At:


Skin Fold




Excessive fat gain in belly region, disrupted sleep pattern


Suprailliac, Subscrapular

Excessive fat gain in love handles and on the upper back


Quadraceps, Hamstrings

Excessive fat gain in hips and legs


Pectoral, Tricep

Androgen imbalance, accumulated fat in chest area for men

Growth Hormone

Knee, Calf

Reflects sleep patterns and overall fat loss



Function of thyroid, accumulated fat 8 inches below armpit


Measurements from each site are then compared to the triceps reading and this identifies which areas of the body have excessive levels of fat relative to the other 11 body fat sites. Some people may have excessive fat in just one area, while others may have several problem areas. Most clients will already have a good idea of what their problem areas are and an experienced practitioner in Biosignature Modulation can often make an accurate visual determination of the problem, but the calipers are quick, easy and reliable.

The BioSignature Method can help you develop a programme based on your unique biological signature. This means faster results and fewer supplements than is possible with the industry’s typically more random and haphazard approach.

The BioSignature Method For Fat Loss & Muscle Gain

This method claims that you can be helped physically, mentally and intellectually. Whilst you can become leaner on this program, it is hoped you will improve more holistically, becoming leaner, healthier, stronger and energised. This method tries to treat people as people instead of having a straightforward one-fits-all approach making it far more successful and much more likely to produce quicker outcomes across a broad selection of the population.

By becoming a Poliquin™ BioSignature Practitioner allows us to offer our clients a well-rounded approach to fat loss by utilizing nutrition and supplementation. It offers results you can see- fast!
