Weight Loss

This page briefly explains that Food Intolerance is different from Allergy and looks at the connection with Weight Loss.

Excess Weight and IgG Food Intolerances

Obesity is a chronic disease which is characterized by severe excess weight and a pathologically increased body fat percentage.

Body mass index (BMI) is a simple index of weight-for-height that is commonly used to classify excess weight and obesity in adults and children. The BMI is calculated by a person’s weight in kilograms divided by the square of their height in meters (kg/mg2).

BMI Definitions


  • BMI >25 kg/m2 = Overweight
  • BMI >30 kg/m2 = Obese
  • BMI > 35 kg/m2 = Morbid Obese

To understand a complete picture of a person’s health one must always take into consideration whether the weight gain negatively impacts on the health of the person.

Excess weight/fat gain can be very stressful for the body pathologically and often can create a psychological burden for the people affected.

If a person is obese or overweight, this means that he or she is carrying excess body fat. The balance between calories-in and calories-out differs for each person. Factors that might affect your weight include your genetic makeup, overeating, monotonous diet, excess carbohydrate and fat intake, and not being physically active.

With obesity, systemic low-grade inflammatory activities are found.

The relationship between obesity and IgG

An IgG food allergy may intensify such inflammatory processes by the production of messenger proteins like TNF-alpha. (a messenger substance which blocks the receptors for insulin). This action impedes the cell’s energy supply. The blood sugar present in the blood cannot be transported into the cell for energy. The liver transforms the blood sugar into fatty acids which are then deposited into the fat cells.

The blockage of the insulin receptors results in more insulin being released and therefore increases the insulin concentration which inhibits the reconversion of fatty acids into blood sugar.

Energy consumption decreases as the individual cells have less energy at their disposal, cell activity is reduced, the basal metabolic rate slows down and the quantity of calories used at rest diminishes.

The identification of foodstuffs that may trigger inflammatory conditions could offer a good possibility to exert a positive influence on the inflammation process through a corresponding change in diet.

IgG seems to be the best indicator for identifying a food as being pro-inflammatory. Every time a food comes in contact with a corresponding IgG antibody, an inflammatory response is launched.

The relationship between obesity and IgG – what some studies have shown

Studies have shown that an IgG guided diet has a positive effect on weight loss and stabilisation of glucose metabolism.

For example, the study “IgG antibodies against food antigens are correlated with inflammation and intima media thickness in obese juveniles” Wilders-Truschnig et al. ECED published online 2007; DOI 10.1055/s-2007-993165 showed a significant correlation between obesity, elevated IgG antibodies and inflammation. Thus, elevated IgG levels for food could be involved in the development of excess weight.


At Perth Allergy Clinic we offer IgG (type 111) testing, through well reputed European laboratories.

Once we receive your test results, our Nutritionists and Allergy Advisors will assemble a dietary food plan based on your results. We will also compile for you a range of easy to cook recipes. The food plan and recipes are regularly rotated so as to keep the choices simple and interesting.

In addition to our IgG testing we offer our Vitality, Longevity and Healthy Ageing (VLA) weight loss program.

The VLA report briefly provides:-

  • Body composition
  • Accurate measurement of BMI
  • Identifies excess fat tissue to target
  • Identifies quantity of muscle mass
  • Identifies quality of muscle mass
  • Indicates your level of toxicity
  • Cellular health (vitality of your cells)
  • Biological age (your cellular age)
  • Intra/Extra cellular fluid balance

From this analysis we can target the progress of your weight/fat loss whilst preserving and building healthy muscle mass and cellular health vitality.
