Diagnosing and treating additional health problems in autistic children or adults, beyond their own autism troubles, is always a challenge under first of parent responsibility. This paper reports on the success of nutrition-based therapeutic approaches for improving the health and solving digestive troubles of a communicating-impaired and initially overweight patient. Symptoms include frequent burping, and diagnoses revealed hiatal hernia and stomach ulcers. Two different diet plans have been successively applied over one year. Each half-year diet impact has been home-monitored by measuring the body-mass data and index. Details on nutrition, supplement and drug intakes, as well as any observations were daily recorded. The first halfyear diet was based on gastroesophageal reflux preventing recommendations, whereas the 2nd diet plan was elaborated from the metabolic typing and gluten intolerance information. Normal body mass index (BMI) values (20-25) were reached during the 1st phase, which was marked by an increase in the intake of food supplement and a reduction in the frequency of drug intakes, especially from the 4th month. After one-year of nutrition-based therapy, the patient health has been generally improved, and the hiatal hernia and ulcer problems have disappeared. A database containing all information recorded throughout the diet plans was created. During the patient body-mass loss, the muscle part increased whereas the fat part dropped. Such fat mass loss observed over the 1st 4 months was possibly correlated to the intake frequency diminution of proton pump inhibitor, acting against the gastric acid secretion. During last 6-months of strict nutrition therapy, the body mass remained stable.

The patient was an adult man with autistic spectra with the following main data recorded in January 2015: 19 years old, 1.74 m height, BMI around 29.8. Starting June 2015, the patient was diagnosed with several pathologies such as, digestive illness, including hiatal hernia, stomach ulcer, and also vitamin-D deficiency.

Dietary Approaches

Diet plans were subdivided into 2 parts. The 1st phase was applied for a 6-month period. It was a combination of dietary therapy (diet and supplementation) with pharmacotherapy (PPI and antacids) in order to heal frequent burping, hiatal hernia, and ulcer. Generally, meals consumed were enriched with fruits and vegetables, and widely diversified with protein, fat and carbohydrate sources. The diet was also based on low-sugar and low-fat meals. Fried and high-fat foods, soda and chocolates, as well as foods known to induce acid reflux such as tomatoes and citrus were avoided.

The 2nd phase starting from the 2ndhalf-year was constituted by gluten and egg free-based foods, combined with a defined diet protocol, carefully applied after a metabolic typing assessment by survey analysis (Metabolic Healing Company, USA).

Recording Data Elaboration

All data such as meals, diet, snacks, supplements, medicines as well as activities were daily recorded in a database created with Microsoft excel. Any other observations noticed during the study period were also recorded in the excel sheet.

Body Data Measurements

All the data, including the body mass (kg), fat, fluid (water) and muscle proportions (%), bone mass (kg), as well as the daily energy requirement (Kcal) were measured monthly using glass body analysis scale (PW 5644 FA, AEG, Germany). The principle of the device consists in measuring the electric impedance within the human body. The device records a pulse electric signal through the body via feet contact, and then measures 6 body data, namely total mass, fat percentage, water percentage as well as bone and muscle masses. The method is based on the bioelectric impedance analysis (BIA) by using appropriate population, age or pathology-specific BIA equations and established procedures.15The BMI, which corresponds to the personʼs mass in kilograms divided by the square of their height in meter, is automatically calculated and listed with the body data. All measurements were consistently recorded at the same time, just after waking up and with an empty stomach.

Results and Discussion

Diet Plans

First diet plan: The first diet period includes dietary therapy and supplements in combination with pharmacotherapy (Figure 1). The dietary therapy is based on both restriction in some food categories and diversification in main nutriment sources. Diet restrictions concern all well-known foods that induce acid reflux such as, fried and high-fat foods, soda, chocolate, coffee, tomatoes and citrus fruits. Nutriment sources target certain fruit and


Changes of self-reported condition during 4 days are shown in figures (Figures 1 and 2). Slight headache was a complaint of about one third women, and the prevalence increased toward 3rd day, but it decreased thereafter to only 10% in females. Hungry was highly recognized among males, but high prevalence was only 2 days. Feeling of coldness was common complaint of women, and it improved only 15%. GI tract distress was rather stationary around 20%. Vivid feeling and activity increased toward the end of fasting. In males increase of vivid feeling was remarkable at day 4 and day 6. Active feeling and vivid mood were significantly associated with skin condition.

Hungry, GI distress and feeling of emesis were significantly associated with fat, muscle weight reduction and decreased BMI. General condition, sleepy feeling, fatigue, depressive feeling, headache, cold feeling, GI distress and hunger were varyingly interrelated. Structure Equation Model by AMOS showed that a significant multiple effects of body fat rate, obesity, body weight, muscle volume and systolic blood pressure at day 2 and day 3 was recognized to those at day 4 (Figure 3).

Subject symptoms, such as skin condition, hungry, cold feeling, GI distress and headache 1 month later was significantly influenced by those of day 2 (Figure 4).

Symptoms, mood and body changes interacted and became better in later days.

vegetable-enriched meals, associated with protein, fat, and carbohydrate categories with high diversity, including grains, meat, dairy products, fish, and snacks in different proportions. Food supplements are constituted by vitamins D/A/E and omega-3 in pure or/and formulated oil forms, as well as magnesium and multi-enzyme complex. The pharmacotherapy includes mainly treatments with a proton pump inhibitor (pantaprazole), antacids (sodium alginate, magaldratum, etc.), and an antihistamine.

Such a therapy combination using diet and drugs has been followed based on practitioner and gastroenterology recommendations, but also by considering the patient overweight and his deficiency in micronutrients. A database containing all daily details of meals, supplements, drugs, physical and brain activities, as well as any observed effects, recorded in a homemade form (example given in additional files), is available. Such data allow us to follow and evaluate the diet plan impact while ensuring a good traceability.

Figure 2 shows the supplement and drug intake global frequencies over this first plan phase. The diagram represents the frequency distribution or count of all supplements consumed in number times per month, compared to that of drugs over the first half-year of diet plan.

During the 1st 4 months, the drug intake frequency is slightly increased while that of supplement is quite unchanged. For the following 2 months, the drug intake is gradually reduced whereas the supplement consumption is clearly increased. Such adjustments have been attempted based on the observation of the whole therapy impact on the crisis frequency and digestive trouble persistence. The diminution of drug intake concerns mainly the PPI, which is often prescribed as the most potent inhibitors of gastric acid secretion for the treatment of gastroesophageal reflux disease. However, digestion processes involving gastric enzymes, especially in the stomach, also need certain acidity for a better digestibility. Additional supplements include mainly the intake of multi-enzyme complex in order to improve digestion, and multivitamin/amino acid/magnesium mixture for helping to maintain normal muscle and nerve function.

On the other hand, some food intolerance and allergies

have been suspected. After a series of food allergy and intolerance tests, which were recommended by a nutrition expert, the patient’s intolerence to gluten and egg, but not in soya and cow’s milk proteins, has been revealed. Therefore, the 2nd diet plan strictly constituted by gluten and egg free-based foods has been started.

Second diet plan: Food and supplement categories consumed for the second phase of nutrition therapy are listed in Table 1. This second diet plan is constituted by diets and supplements without drugs. Moreover, a metabolic typing assessment has been carried out under the control of private metabolism experts. This approach aims at identifying individual metabolic requirements based on a testing questionnaire (physical, diet, psychological traits) established since 38 years of research and development by William L. Wolcott.16 It also considers the input of thousands of practitioners and hundreds of thousands of users world-wide. After the metabolic typing identification as balanced and mixed oxidizer dominance, a diet plan targeting the utilization of optimal foods for reaching recommended nutrition ratios 45% carbohydrate, 35% protein, and 20% fat was started. In theory, the balanced and mixed oxidizer dominance metabolism reaction type in the patient corresponds to the combination of 2 homeostatic system regulations, named autonomic nervous system (ANS) and oxidative system (OS). The ANS is in relation to the speeding (sympathetic) and slowing (parasympathetic) heart rates. Thus, the term balanced dominant is used for people whose organs and glands are balanced between sym-

pathetic and parasympathetic influences. The OS corresponds to the conversion rate of nutrients to energy within body’s cells, and influences in particular dietary requirements. Therefore, a nutrition plan combining various food categories as listed in Table 1 has been followed while observing the digestion trouble evolution and any improvement. The goal was to make adjustments for reaching the best diets tailored to the patient.


Figure 3 shows the body data changes over one year under 2 diet plans. Body-mass data were monthly measured to monitor the effect of the whole nutrition therapeutic approach, including 2 successive diet plans. Body data correspond to body mass, fat, fluid (water) and muscle proportions and bone mass, as well as the daily energy requirement (Kcal). The latter corresponds to the amount of energy that the body requires per day during complete rest, that is, while sleeping where the body temperature is almost unchanged, and on an empty stomach. All data obtained with the home-model impendence meter (PW5644FA, AEG) for this investigation were comparable with those measured at the general practitioner using a professional device BIOZM2. Only a difference around 1% was observed, for instance, with the body fluid data. As indicator, standard errors between the results obtained with home-model and professional devices were around 1% with the body water percentage and less than 5% for the body-fat percentage. It is to be noticed that, except the body mass in absolute value, the other body data monitored during our investigation were analyzed in terms of relative data changes over one year.

It appears that: (1) the body-mass decreases from 80.2 kg to 72.3 kg during the 1st half-year, before reaching a stable value around 67 kg after the second diet plan; (2) the body fat follows the same trend with a sharp decrease for the first diet plan, and remains constant after 9 months of nutrition therapy; (3) there is a gain in the cumulated body water and muscle mass; and (4) the bone mass was unchanged over one year, indicating trends toward good health features.

The decrease of the body mass and fat with the increase of muscle mass during the first 4 months of nutrition-based therapy is naturally correlated to a diet containing all recommended foods characterized by fruit and vegetable-enriched and varied foods, but also with restricting diet without soda, chocolates, onions, etc. It may be due to the combination of different effective dietary strategies for reducing mass such as lower fat, higher protein, and lower glycaemic index diets.17 The fact that the body fat decreases while the muscle mass increases is coherent to the effective diet strategy for mass loss.

However, the diminution of body fat compared to that of the PPI intake frequency is striking as shown in Figure 4. Both indicators decrease in similar proportions over the 4 months of the 1st diet plan. By searching in the literature, it has been reported that omeprazole and other PPIs delay gastric emptying,18,19 which induces postprandial fullness, dyspeptic symptoms, gastrointestinal bacterial overgrowth, and subsequent mass loss.20 On the contrary, long-term treatment of PPI is rather associated in general trend with mass gain in patients with gastro-oesophagus reflux disease.21

Subsequently, the PPI intake was stopped in the beginning of the 2nd half-year after which the eructation symptoms were diminished.

Figure 5 shows the changes in the BMI and energy requirement over one year under the 2 diet programs. The BMI value reaches the normal zone (20-25) after 3 months of the first diet plan while continuing to decrease down to 22.5. This value remains practically unchanged after 7-8 months of nutrition therapy. The energy requirement follows the same trait for reaching also a constant value close to 1700 kcal.

It appears that both BMI and body data for the patient age and height stabilized at normal values after 6-months of nu-

trition-based home-made therapeutic approaches. Also, according to the baryta-based radiography examination of oesophagusstomach- duodenum, hiatal hernia disappeared after one year of nutrition therapy. The frequency of crisis is also reduced from 5 per month in the first half-year to 3 during the second half-year with sometimes one crisis per month. Such a success may be simply explained by reaching the so-called “optimum nutritional balance” with selected foods and diet for the patient. If the first diet plan enables his weight loss for reaching a normal BMI by specific restriction and diversification in foods, the second one rather allows his BMI to be stable by optimizing his nutrition, thanks to the metabolic type results. In addition, the elimination of gluten and eggs from the second diet plan certainly contributes to the improvement of his digestive health by avoiding allergies and food intolerance.




This investigation shows the success of nutrition-based therapeutic approaches for solving autistic digestive troubles. Two successive diet plans allow us to treat the patient overweight, reaching after four months a normal BMI value that remains stable over one year. The general health of the patient is improved as his crisis frequency is reduced, and the related digestive disorders especially shown by the presence of hiatal hernia, and ulcer are solved. Such a communicating-limited patient management is a real challenge, but also very enriching experiences for his family surroundings, as well as sustainable by the database establishment after recording all information throughout the diet plans. An obvious perspective would be to process such data by computational routes to access in easier and faster manners any request information for similar or other cases. In purely scientific and medical viewpoints, our approach will restart the debate on the mechanism of gastric acid secretion inhibitors (proton pump inhibitor) on the fat mass loss, which would be favorable for fighting overweight and obesity.
