MLB Outfielder took the Alcat Test and visited the Cell Science Systems Laboratory.

“I took the test and immediately told myself that if this is right and this is right for me I will do this by the book. I had a severe reaction to hazelnut and then some moderate reactions to some other foods, cut those foods out, cut all sugar out for a month and immediately lost thirty five pounds.”

Cliff Floyd


“I am 6-weeks into the elimination and rotation diet and the results have been nothing short of a miracle! I have lost 13 pounds, my skin is clearing up, I sleep well, digest well, feel strong and have a lot of energy. I realize now that I have had food intolerances all of my adult life – I am only sorry that it has taken this many years to finally get to the cause of my health problems. If I had only known that good health was really so simple to achieve. Thank you, Alcat!”

Laura from Kansas



“At 220 pounds I had been diagnosed with Osteoarthritis, Adult Onset Asthma, and High Blood Pressure. I was Border Line Diabetic and had Pitted Edema in my legs to the extent I wore support hose for 5.

My ailments were only out numbered by the medications I took for them. I started trying to lose weight.

Without much support or direction, I tried several nationally advertised well known diet plans. I would lose a little and gain even more. After approximately 3 years of this yo-yo I had gained an additional 32 pounds, and was now at my top weight of 252 pounds. Then I found the Alcat Test through a book I was reading. Unlike the “diet plans” I had seen before, the Alcat Test spoke of food sensitivity and a medical reason why my body was not responding to a healthy diet.

After taking the Alcat Test, I found my most severe food sensitivities were some of the healthiest foods I ate, and I ate them on a daily basis. (Lettuce, tomatoes, green peppers, onions, and lemons, to name a few). When I started the Alcat Test rotation diet I was sure this was something that could change my life. When I eliminated the foods I was intolerant to I started losing weight almost immediately, an amazing 15 pounds the first 2 weeks. In the following 11 weeks I lost an additional 70 pounds. After approximately 10 days I was able to stop taking all six prescription medications. I lost an incredible 16 inches on my waist line; and went from a 3XL shirt to a medium.

The Alcat Test is absolutely amazing.”

Metabolic Conditions

Inflammatory signals play a role in all metabolic disorders. They mediate the immune response and the activation of the innate immune system. Neutrophils (the main group of white blood cells) secrete their biochemical contents to fight damaging particles, after which they perish scavenger cells (phagocytes) eat the cell debris for removal. If this is an ongoing process a lot of energy is directed into the immune system.


The Alcat Test helps to identify dietary triggers of Inflammation.


Weight Gain and Obesity

It’s true that we gain weight when we eat more than we burn off.  Many factors can impact the , “burning off” part of the equation.  Chronic inflammation is one of them.


Weight gain can also be caused by hypothyroidism, food sensitivity (as mentioned) Cushing’s syndrome, organ disease, prescription drug use (e.g. antidepressants) anxiety, blood sugar imbalance, essential fatty acid deficiency or lack of sleep. Many people respond to stress or depression by eating excessively. Reactions to foods are not always immediate. They may be delayed by several hours, possibly even one or two days. Common signs include;bloating and swelling in the hands, feet, ankles, abdomen, skin and around the eyes. Much of the weight gained is fluid retention caused by inflammation and the release of certain hormones. In addition, there is fermentation of foods, particularly carbohydrates, in the intestines which can result in a swollen distended belly and gas production. Inflammation associated with food sensitivities can lead to weight gain and obesity 1, 2.


According to the WHO a BMI (body mass index) equal to or more than 25 is considered overweight.  A BMI equal to or more than 30 is considered obese 3. Obesity can lead to pathological, chronic disorders like diabetes, cardiovascular conditions and cancer 3. The WHO suggests that in 2008 more than 1.4 billion adults were overweight and of these over 200 million adults were obese 3. Obesity is a preventable condition according to the WHO.

…Healthy weight loss!

The inability to achieve and maintain a healthy weight might be silent inflammation (chronic low-level inflammation) 4.  BMI is based only on the size in relation to weight, but does not consider the real “body composition”, including abdominal or peripheral fat accumulation (fat around organs).  Hence, measurement of BMI without measurement of body composition, may be misleading.  It is possible to not be overweight but to be over fat.

What causes overweight?

How much does the lean, fat-free body part weigh, and how much does the fat? A person can be overweight without a high body fat percentage. The overweight may come from muscle mass. When it is placed in relation to the fat percentage, muscle mass is denser and therefore weighs more. A person who is not “fat-overweight” is not under the same disease risks, such as a “fat-overweight”. On the other hand, people may have a too high fat content but “ideal weight” according to the BMI. This condition is called normal weight obesity. Consequently, the risk of disease and inflammation is higher, even though they fall within the ideal weight category.

Thus the fat proportion plays the biggest health role, regardless of the weight. Too much muscle mass pose no health risks. In contrast to the widespread opinion that fat is stored in the form of a wobbly mass as excess calories, it is metabolically active tissue 5. Leptins are hormones which are produced in fat cells 5. They send signals to the brain that you are sated. But if excessive fat is accumulated – particularly in the abdominal and peripheral area – adipose tissue then becomes an important endocrine tissue and sends inflammatory biochemicals 5. These inflammatory mediators cause low grade systemic inflammation in “fat-obese” people even though weight is normal according to the BMI!

Several studies of the Alcat Test show characteristic weight loss going along with the Alcat program. A study performed with 27 obese patients shows an average weight loss from 91.37 ± 10.56 kg to 74.6 ± 6.76 kg after following the Alcat Test results and rotational diet for 12 weeks (Akmal et al., 2009- find below).

The Alcat Test program provides an excellent basis for a sustainable weight loss and weight management. The program enables a diet that helps to prevent unwanted cellular defense responses to food particles. The Alcat Test is not a diet, but is a basis for enabling intelligent and profound dietary modification.


Metabolic Syndrome

Also known as Reavan syndrome or Syndrome X, the Metabolic syndrome is not a disease but combines multiple symptoms: obesity, fat metabolic disorder (dyslipidemia), elevated blood pressure, and insulin resistance. It is also associated with several additional conditions like sleep apnea, male hypogonadism and polycystic ovary syndrome 6. The widely accepted cause of the metabolic syndrome is diet and lifestyle related. . It starts with overweight or obesity which leads to insulin resistance. Insulin in turn controls blood sugar levels. High levels of insulin may cause insulin resistence and later, type II diabetes.  (The inflammatory mediators produced by immune cells, particularly, TNF alpha and IL-6, are known to block insulin receptors.)

Diabetes mellitus

Diabetes mellitus is a group of chronic metabolic disorders, which can cause severe long-term conditions such as cardiovascular disease (heart disease and stroke) and kidney failure 7, 8. Diabetes is of two types: type I diabetes (decreased production of insulin), type II diabetes (insulin resistance) and gestational diabetes (pregnant women with high blood glucose levels) 9. In all cases, the blood sugar level can no longer be solely regulated by the body and is therefore abnormally increased. It is estimated that approximately 347 million people worldwide suffer from diabetes 9.

Cardiovascular disease (CVD) and conditions


Arteriosclerosis is a condition in which plaque builds up inside the arteries with local inflammatory processes 10. Consequently the arteries become clogged, which limits the transport of oxygen-containing blood to the organs. It can lead to CVD. e.g. heart attack and stroke. The plaque can consist of fat, cholesterol and other components in the bloodInflammation plays a major role in turning cholesterol into plaque.

Cardiovascular diseases

CVD includes pathologic conditions affecting the heart and blood vessels like coronary and rheumatic heart disease or peripheral arterial disease and deep vein thrombosis (blood clots) 11. CVDs represent the number one cause of death worldwide 11, 12. Main risk factors include unhealthy diet, lack of physical exercise, smoking, and excessive use of alcohol 11.


Test recommendations for weight management, metabolic and cardiovascular conditions

What test?



Alcat Test

for food intolerance & chemical sensitivity


PreviMedica Program



Validation studies show that the Alcat Test can have very positive effects on gastrointestinal disorders:


  • Alcat Test diet modification can identify food,  chemical or environmental triggers


  • Alcat Test diet may help to restore or prevent leaky gut syndrome by identifying/eliminating potential inflammation causing dietary triggers


  • Immune system can recover and strengthen

Methyltetrahydrofolate Reductase Genetic Mutations

  • Heart & Brain Health: MTHFR mutation can be associated with metabolic or neurological health conditions


  • Determine or prevent cardiovascular risk assessment
Adrenal Stress Profile Stress can cause inflammation and thus cause IBS.


  • Checking the circadian secreted levels of cortisol and DHEA can be a window into how well the body is managing this critical component of chronic illness.
Telomere length test
  • The length of telomeres give good information if there might be a degenerative process
  • Prevention of too fast aging
Vitamin D
  • Vitamin D deficiency might promote metabolic or gastrointestinal disorders, especially IBS and even colon cancer, LINK to Vit D recommended Pathogenesis because of study back-up


Effectiveness and validation of the Alcat Test

Beginning in 1988, and carrying through to the present, several clinical studies have been performed to evaluate the effectiveness of the Alcat Test. Some of which were “double-blinded*” to see how well the test results correlate with actually eating the food.


A valid test for food intolerance should show the effect of food substances on those cells of the immune system which are associated with the inflammatory process.


(Note to us: it would be good to link to references that link neutrophil activation to certain disease conditions, LINK to Alcat Test immunology section?).








If the test results are valid there should be in a concordance with symptoms (e.g., gastrointestinal complaints), and correlate with double blind oral exposure.


(*Double-blind studies: To obtain an unbiased outcome the study must be carried out in double blind fashion wherein neither the doctor (investigator) nor test subject knows whether the food they are re-introducing has been indicated by the blood test as being either positive or negative. The test results are evaluated to see if they correlate with this, the, “gold standard” – a double blind oral challenge. This is a rigorous and time consuming protocol that yields an objective evaluation of both the sensitivity and the specificity of the test.)


Why is that important?


This is important because you want the test to correctly identify reaction provoking substances; but, you also do not want the test to show false positives. The first parameter is called, “sensitivity”. The second is called, “specificity”. A false positive would cause you to needlessly eliminate a safe food.


Scientists have shown that in patients with irritable bowel syndrome, atopic eczema, allergic rhinitis or migraine the Alcat Test can detect those foods that cause the above symptoms. The Alcat Test has shown high correlation with double-blind oral challenges: 83.4% with foods  and 96% with food additives.
