Maintaining a healthy weight involves both art and science

When it comes to weight loss, one size doesn't fit all. Your metabolism and dietary needs are influenced by a number of factors including:

  • how your body uses insulin to optimise your blood sugar and energy levels
  • how your thyroid function regulates your energy expenditure
  • how well your liver metabolises fat

Issues with your body's metabolic pathways can not only sabotage your weight loss goals but can also contribute to a broader range of chronic health issues. The Healthy Weight Check combines insights from these blood markers with a teleconsult with our clinical nutritionist to design a custom nutrition plan to suit your body's specific needs. As featured in the Daily Mail.

What we test

Metabolic

Insulin resistance can lead to difficulty losing weight, distinct abdominal fat, fatigue, bloating and sugar cravings. Identifying insulin resistance early and committing to lifestyle changes can ultimately help the progression to diabetes.

This blood test measures:

If you have diabetes your body doesn't process glucose effectively.

A hormone produced by the pancreas that helps to control blood glucose levels and plays a role in controlling the levels of carbohydrates and fats stored in the body.

The HOMA score is a standard measure of insulin resistance, It is calculated as follows: (Blood Glucose X Fasting Insulin) / 22.5.

The main storage form of fatty acids in the body. Elevated triglyceride levels may contribute to hardening of the arteries, and increase the risk of heart disease or stroke.

Thyroid Function

Your thyroid gland produces hormones that regulate growth and energy expenditure. Thyroid disorders are quite common, and many people don’t have any symptoms at all. This thyroid test screens for the thyroid hormones that play a key role in regulating the body’s metabolism.

This thyroid test measures:

Communicates with the thyroid gland to produce T3 and T4 which regulate metabolic functions. High TSH thyroid test levels indicates an underactive thyroid, and low levels an overactive thyroid.

Measures the thyroxine that is freely circulating and able to regulate metabolism. High FT4 thyroid test levels indicate an overactive thyroid, and low levels an underactive thyroid.

Measures the triiodothyronine that is freely circulating. High FT3 thyroid test levels indicate an overactive thyroid, and low levels an underactive thyroid.

Liver Function

Your liver processes drugs and alcohol, filters toxic chemicals, stores vitamins and minerals, and makes bile, proteins and enzymes. This liver function test examines enzymes and other markers for evidence of damage to your liver cells or a blockage near your liver which can impair its function.

This liver function test measures:

Bilirubin tests are use to screen for or to detect and monitor liver disorders or haemolytic anaemia.

Alkaline phosphatase (ALP) is an enzyme located mainly in the liver and the bones. High levels can indicate liver disease.

Aspartate aminotransferase (AST) is an enzyme created mainly by the liver and the heart. High levels can indicate damage to your liver caused by alcohol, drugs or hepatitis.

Alanine aminotransferase (ALT) is an enzyme mainly produced by the liver. A good indicator of liver damage caused by alcohol, drugs or hepatitis.

Gamma-glutamyl transferase (GGT) is a liver enzyme which can be used to diagnose alcohol abuse as it is typically raised in long term drinkers.

Albumin is a protein which keeps fluid from leaking out of blood vessels, nourishes tissues, and carries hormones, vitamins, drugs, and ions like calcium throughout the body. Albumin is made in the liver and is sensitive to liver damage.

A measure of all of the proteins in the plasma portion of your blood. Proteins are important building blocks of all cells and tissues - they are important for body growth and health.

Inflammation

The hsCRP test is a highly sensitive quantification of CRP, a protein released into the blood by the liver during inflammation, and has been associated with the presence of heart disease.

This blood test measures:

A high-sensitivity C-reactive protein (hs-CRP) test measures low levels of CRP and may be used to help evaluate an individual for risk of cardiovascular disease

Test instructions

Fast from all food and drink (other than water) for at least 8 hours, and no more than 12 hours prior to your test.
