Abstract
Nesfatin concentrations are positively correlated with beta cell function. However, it is unclear whether diet composition mediates this relationship. We recruited 27 overweight individuals who practiced Orthodox fasting (OF), a subset of the Mediterranean diet (MedDiet), for 7 weeks. Fourteen overweight people who practiced 16:8 time-restricted eating served as control group. Anthropometric parameters, biochemical data and adipokine levels were evaluated at baseline and after the end of the diet period (7 weeks from baseline). Subsequently, participants were asked to return to their usual eating plans, and an additional evaluation was performed 5 weeks after the end of the research diets (12 weeks from baseline). We observed a significant and negative correlation between HOMA-B and nesfatin values at 12 weeks, only in the OF group (r = -0.455, p = 0.01). In conclusion, returning to normal eating habits after 7 weeks of strict adherence to MedDiet affects the homeostatic balance between insulin secretion and nesfatin.

A Mediterranean Eating Pattern Combining Energy and Time-Restricted Eating Improves Vaspin and Omentin Concentrations Compared to Intermittent Fasting in Overweight Individuals.

Abstract
Athonian Orthodox fasting (AOF) is characterized by energy- and time-restricted eating (TRE) and is based on the Mediterranean diet. We aimed to investigate the impact of AOF compared to another TRE model on vaspin, omentin, nesfatin, and visfatin levels. We included 25 individuals (mean age 50.3 ± 8.6 years, 24% men) who practiced AOF and abstained from animal products, with the exception of seafood and fish. This group adopted a 12 h eating interval (08.00 to 20.00). In total, 12 participants (mean age 47.7 ± 8.7 years, 33.3% men) who practiced 16:8 TRE (eating from 09:00 to 17:00) and were allowed to consume meat served as the controls. Anthropometric and dietary data and adipokine levels were prospectively collected at three time points: at baseline, after the end of the diets (7 weeks), and 5 weeks after the participants returned to their typical eating habits (12 weeks from baseline). Vaspin levels decreased [795.8 (422.1-1299.4) (baseline) vs. 402.7 (203.8-818.9) (7 weeks) pg/mL, p = 0.002] and omentin levels increased [568.5 (437.7-1196.5) (baseline) vs. 659.0 (555.7-1810.8) (12 weeks) pg/mL, p = 0.001] in the AOF group, while none of the analyzed adipokines changed significantly in the TRE group. The variations observed in vaspin and omentin concentrations in the AOF group were independent of age, sex, changes in anthropometry and fat intake. In conclusion, AOF can significantly reduce vaspin and increase omentin, whose levels are known to increase and decrease, respectively, in obesity and type 2 diabetes. The implications of these findings for cardiometabolic health warrant further investigation.

Abstract
We prospectively assessed changes in free 25-hydroxyvitamin D [25(OH)D] and vitamin D binding protein (VDBP) among overweight adults who followed a pescatarian Orthodox intermittent fasting regimen (n = 59) and controls who followed a low-fat 12:12 diet (n = 46). Total and free 25(OH)D, parathyroid hormone, VDBP, anthropometric data, and amino acid intake were evaluated in both groups at three time points: at baseline, 7 weeks after diet implementation, and 5 weeks after participants returned to their usual eating habits (12 weeks from baseline). An increase in amino acid intake between baseline and 12 weeks was independently correlated with higher free 25(OH)D values at 12 weeks for both groups. Our findings suggest that diet can affect free 25(OH)D concentrations, through variations in amino acid intake, independently of exposure to sunlight, providing novel mechanistic insights into the future planning of vitamin D supplementation strategies. However, this hypothesis needs to be tested in larger studies.

Abstract
We aimed to evaluate sex differences in changes of lipid profiles in a cohort of metabolically healthy adults following Orthodox fasting (OF), as well as to assess a potential role of vitamin D status in mediating these variations. 45 individuals (24 premenopausal females, 53.3 %) with mean age 48.3 ± 9.1 years and mean Body Mass Index 28.7 ± 5.8 kg/m2 were prospectively followed for 12 weeks. Anthropometry, dietary and biochemical data regarding serum lipids, and vitamin D status were collected at baseline, 7 weeks after the implementation of OF, and 5 weeks after fasters returned to their standard dietary habits (12 weeks from baseline). According to 25-hydroxy-vitamin D [25(OH)D] measurements, participants were divided into two groups: those with concentrations above and below the median of values. Females with 25(OH)D concentrations below the median manifested a non-significant reduction by approximately 15 % in total and low-density lipoprotein cholesterol during the fasting period, followed by a significant increase 5 weeks after OF cessation (170.7 vs. 197.5 and 99.6 vs. 121.0 mg/dl respectively, p < 0.001). In contrast, males with 25(OH)D levels below the median demonstrated an inverse, non-significant trend of increase in lipid concentrations during the whole study period. Our findings suggest strikingly different inter-gender lipid responses to a dietary model of low-fat, mediated by vitamin D status. Further studies are necessary to reveal the underlying mechanisms and assess the importance of these differences with respect to cardiovascular health and the benefit of vitamin D supplementation strategies.

Abstract
The exact mechanisms mediating the metabolic effects of Orthodox fasting remain unclear. Plasma adiponectin, biochemical and anthropometrical data were evaluated in 55 Orthodox fasters (OF) and 42 time-restricted eating controls (all women, mean age 47.8 years) at three time points: baseline, end of the dietary intervention (7 weeks) and 5 weeks after participants returned to their typical dietary habits (12 weeks from baseline). In the OF group, there was an increase in adiponectin values at 12 weeks compared with baseline (9815.99 vs 8983.52 mg/ml, p = 0.02) and a reduction in body fat mass between baseline and 12 weeks (35.44 vs 32.17%, p = 0.004) and between 7 and 12 weeks (35.33 vs 32.17%, p = 0.003). In the same group, an inverse correlation between adiponectin and waist circumference values was observed over the entire study period. Our results provide novel evidence that Orthodox fasting has favourable metabolic effects related to improved adiponectin concentrations.

Abstract
A hypocaloric diet, based on Orthodox fasting (OF) was followed by 29 overweight adults. A low-calorie, 16/8, time restricted eating (TRE) pattern was followed by 16 age- and weight-matched participants. Anthropometric, lipid, glycaemic and inflammation markers were assessed at baseline, at the end of the intervention (7 weeks from baseline) and 6 weeks after the cessation of diets (13 weeks from baseline). There was a trend of weight loss in both groups, which was evident at week 7 (TRE: -2.1 ± 1.0; OF: -2.0 ± 0.5 kg, p < 0.001 from baseline) and remained significant at week 13 (TRE: -2.9 ± 0.7; OF: -2.6 ± 0.3 kg, p < 0.001 from baseline). In the OF group, lipid concentrations declined at week 7 compared with baseline, increasing at week 13 compared with week 7. Our findings suggest that OF promotes a decrease in lipid concentrations, which however, is not evident 6 weeks after its end.

Abstract
For seven weeks, 37 overweight adults followed a hypocaloric diet based on Orthodox Fasting (OF). A hypocaloric, time restricted eating (TRE) plan (eating between 08:00 to 16:00 h, water fasting from 16:00 to 08:00 h) was followed by 23 Body Mass Index (BMI)-matched participants. Anthropometric, glycaemic and inflammation markers and serum lipids were assessed before and after the diets. Both OF and TRE groups demonstrated reductions in BMI (28.54 ± 5.45 vs 27.20 ± 5.10 kg/m2, p < 0.001 and 26.40 ± 4.11 vs 25.81 ± 3.78 kg/m2 p = 0.001, respectively). Following the intervention, the OF group presented lower concentrations of total and low-density lipoprotein-cholesterol, compared with the pre-fasting values (178.40 ± 34.14 vs 197.17 ± 34.30 mg/dl, p < 0.001 and 105.89 ± 28.08 vs 122.37 ± 29.70 mg/dl, p < 0.001, respectively). Neither group manifested significant differences in glycaemic and inflammatory parameters. Our findings suggest that OF has superior lipid lowering effects than the TRE pattern.

Abstract
The effect of a mixture of scopolamine and hyoscyamine (98:2) on developing chick embryos was investigated. The embryos were exposed at 2 stages of development to various doses of this mixture via yolk sac injection. This resulted in deaths at different stages of prenatal development, as well as various malformations and reduction deformities. These findings suggest that the studied mixture has a teratogenic effect when injected into the yolk sac of developing chick embryos.
