|Many of these foods contain supposed allergens and have thus to be eliminated from your diet... is it any wonder that this triggers weight loss? Hardly...|
82 patients (24 male, 58 female) were included in the study. The mean age was 42.04±11.81 (18-65 years). All of them were "unable to lose weight", i.e. patients who said of themselves that they couldn’t lose weight by diet programs and who had a positive reaction to at least one nutrient in food intolerance test and a BMI value ≥ 25kg/m² - in other words: the subjects were the average Internet bullet-in board dwellers searching for the "magic key" to weight loss.
This is obviously an important fact, because it increases the significance of the study for said group of subjects. Whether the results are significant for anyone else, though, is questionable, since patients who had no food reaction in food intolerance test were excluded from the study. The same goes for subjects who had chronic diseases like diabetes mellitus, coronary heart disease, renal diseases, etc., or individuals who use(d) weight loss drugs and who had allergy to any drug or food and who overuse medications or have pure menstrual migraine or headache that associated a disorder.
No health benefits from "eliminating" foods: Interestingly, the food intolerance elimination diet failed to do what its proponents say it's actually doing: Improve the subjects health. With the exception of a statistically significant decrease in triglyceride levels, there was no improvement in health markers (fasting blood glucose, A1C, total cholesterol, HDL-cholesterol, LDL-cholesterol, AST, and ALT) the scientists didn't observe in the control group, too.As you can see in Figure 1, this particular group of subjects saw significant benefits from following a diet that did not allow the subjects to consume any of the foods to which they showed an IgG response in the previously conducted food intolerance test for 6 months. Otherwise, the diets of the elimination diet (ED) and control diet were personalized diets with "identical" (according to the size, weight, physical activity, dietary habits and socioeconomic status) energy content.
