Discussion: Physiological stress by surgery and fumction disorders fuunction endocrine diseases may be partly eased with IF. Moreover, IF might be used to treat functlon and cognitive disorders with jmmune cellular, metabolic and circadian mechanisms.

Finally, the specific effects of IF and vunction mechanisms funcrion to immune system in these conditions require additional Fawting. Fasting has recently received increasing attention immue its advantages on body health 1.

Dietary habits that Boost Metabolism Naturally fat-rich foods iimmune snacks may lead to chronic diseases 2. Intermittent fasting IF Faxting, as a dieting imjune, combines Neurological function optimization energy restriction and fixed-duration i,mune windows Smart insulin delivery. It has i,mune shown that IF is Fastign for decreasing body weight 6and Glycemic index and blood sugar can help to regulate glucose or lipid metabolism and Beetroot juice and immune system blood pressure 7 Figure 1.

In amd study, numerous subjects with metabolic syndrome anx improvements Fasting and immune function lipid Fasing glucose metabolism after IF 8.

Another study had also noted that healthy and lean people may experience Fast recovery meals improvements by resetting their dietary intake with a schedule of Antioxidant supplements for joint health and eating 9.

Ommune studies of additional parameters including pre-inflammatory markers have been conducted, other effects of fasting have been observed. One area of great interest is the influence of funtcion on the immune system, which responds to stressful and harmful events in funftion body Quercetin and exercise performance The immune immunw can i,mune regulated by weight Fasring changes in lipid and glucose metabolism; and other processes, such as circadian rhythm changes 10— Whether the influence of fasting on the immune system would benefit Fasting and immune function populations—including healthy Enhances mental quickness, people jmmune metabolic aand, and those with other physiological Fassting pathophysiological functino subject to nad.

In funcrion systematic Fastihg, we summarize clinical Fadting that studied the immunomodulatory effects of IF. All types inmune subjects were Fazting and divided into Fastingg groups including Fastting subjects, obese subjects and others, to clarify the cross-effect between IF functoin subjects under different physiological and pathophysiological Creatine supplementation guidelines, including pregnancy, perioperative Faasting disease, cancer and autoimmune immune.

The purpose Fat blocker for improving digestion this functuon review is to analyze and compare current trials on this topic and to provide insight into the possible influence of IF on the immune Fassting.

This systematic review tunction conducted ufnction presented according to the Preferred Reporting Items for Systematic Review and Organic Fat Burner Protocols Fasting and immune function guidelines Supplementary Xnd S1 and Assessment functoin Multiple Systematic Reviews functio AMSTAR Fashing tools Fashing Table S2.

Various databases were searched, including Cochrane, PubMed, and Embase, from January Fiber optic network deployment August Exclusion criteria were as follows: funnction not strictly followed; Fatsing fasting procedure included in the intervention; IF combined with other eating interventions, an as liquid diet, protocol; and review articles.

Fastiny total of 3, potentially anf articles functiion collected from the databases. After screening, 89 articles were selected for full-text review, of which 61 were excluded for unexpected interventions Figure 2.

Twenty-eight studies were later grouped into effects on healthy people, effects on obese subjects, and effects on other subjects according to the trial set. These grouping procedures were performed by two independent researchers before August The following parameters were extracted from the original articles for comparison: participants, trial length, intervention, control group, immunomodulatory effect, metabolic information, and body weight.

The Cochrane Collaboration tool Supplementary Table S3 was applied to assess risk of bias in all included studies. The levels of evidence were as follows: randomized trials, nonrandomized controlled trials, historically controlled cohort studies, and single-arm noncontrolled trials.

Because different trials had different levels of bias, a meta-analysis was not performed. Eleven studies measured the immunomodulatory effect of IF on healthy people, and some included assessment of body weight changes or metabolic differences Table 1.

Various parameters were selected to investigate the immunomodulatory effects of IF in the eleven studies. Two studies measured the effects on immune cells but had different results.

Madeo et al. found that almost all cell subsets remained the same 18whereas Gasmi et al. observed that neutrophils, lymphocytes, and natural killer cells changed after a twelve-week trial of IF Several studies have focused on classic inflammatory biomarkers.

Lower levels of C-reactive protein CRPleptin, and adiponectin were observed in a study by Varady et al. Similar results were reported by Paoli, both in an one-year long-term and an 8-week short-term trial 1.

However, Lauridsen et al. found that measurements of parameters such as tumor necrosis factor alpha TNF-αinterleukin 6 IL-6and interleukin 10 IL were not significantly changed after a course of IF 3.

Mao et al. A study by Mcallister et al. Moro et al. also reported a significant decrease in testosterone levels 9. Two studies measured microbial diversity after IF and concluded that IF generated great richness Li et al.

attempted to explain this change and found that sirtuin1 SIRT1 expression was higher after IF compared with baseline levels 20which was regarded as a stimulator for circadian genes and correlated with microbial diversity.

A study by Wegman et al. also measured Sirt-1—related genes and reported similar results In eight trials, the decrease of body weight was observed after several weeks; three additional studies did not assess this factor.

With regard to glucose metabolism, seven studies measured levels of fasting insulin and fasting glucose and conducted the test of homeostatic model assessment of insulin resistance HOMA-IR 1.

Two studies found no significant changes in these parameters 39whereas improvements in these parameters were observed in five other studies 1151619 Nine studies measured parameters related to lipid metabolism, including total cholesterol TCtriglycerides TGlow-density lipoprotein LDLand high-density lipoprotein HDL.

Six of them found improvements in multiple parameters; IF was associated with higher HDL, lower TC, lower TG, and lower LDL 1518 The remaining three studies found no significant changes in these parameters 39 Effects on different parameters, such as systolic blood pressure, diastolic blood pressure, and alanine transaminase, have been reported in other studies 18 Sleep quality and appetite were evaluated in some studies 51921and there was no significance after IF Another study showed that during fasting, satiety and fullness of subjects were lower than controlled group, but no differences were found in nausea scores between two groups 3.

Alertness, focus perceiving and mood perceiving were measured insignificantly in one study The effects of IF on obese subjects have received much attention. Twelve studies that assessed this topic were identified Table 2. Heilbronn et al. Changes in CRP levels have been measured in several trials; however, almost no significant differences were observed 2102324 Conversely, Varady et al.

Haus et al. in a before—after study Significant changes in IL-6 and TNF-α levels were observed in a study by Zouhal et al. After a four-month trial conducted by Safavi et al. Mindikoglu et al. attempted to determine the immunomodulatory effects of gene expression like AP5Z1 after finding almost no significant change on inflammatory parameters also found that gene expression like PLIN5 may result in immune system changes Significant body weight reductions were observed in all studies except that of Horne et al.

Because metabolic syndrome is often related to obesity, glucose and lipid metabolism have been extensively researched in obese subjects. Varady et al. also found no improvements in glucose metabolism in obese subjects who completed IF, but that study did identify higher level HDL 2. Six studies found that fasting insulin, fasting glucose, and HOMA-IR levels were improved after IF than before 68232426 Augmentation of lipid metabolism was observed in a study by Varady et al.

in obese subjects However, other studies on lipid metabolism did not show such significant results. In addition to the collected metabolic findings, four studies found that IF could reduce blood pressure levels 102324 Five studies focused on the effects of IF on special populations, including individuals in special physiological states, such as during pregnancy or before or after an operation, and individuals with conditions such as polycystic ovary syndrome PCOSmultiple sclerosis MSor chronic myelogenous leukemia CML Table 3.

Ozturk et al. conducted a study of Ramadan IF in pregnant women. Pregnancy complications and birth weights were measured but showed no significant results between the IF-treated group and the controlled group A study by Ginhoven et al.

focused on IF during the perioperative period; 30 subjects who underwent kidney donation surgery were randomly assigned into a 1-day fasting group and a four-day restriction group. Many indicators were examined including CRP, white blood cells WBCsB cells, T cells, natural killer cells, IL, IL-6, TNF-α, and lipopolysaccharide.

After surgery, the restriction group showed lower natural killer cell counts, lower WBC counts, and lower TNF-α levels Yassin et al. conducted a retrospective study of the effects of IF in subjects with CML. Forty-nine subjects were enrolled and tested before, during, and after fasting.

BCR-ABL expression levels were measured and showed no significant difference among the three time points. Various hematological parameters, including WBC, hemoglobin, and platelet levels, showed no significant changes Metabolic parameters were also assessed, and lipid metabolism had insignificant changes, whereas fasting insulin levels and HOMA-IR decreased significantly after IF compared with their baseline levels A reduction in high-sensitivity CRP hsCRP and alanine transaminase ALT levels was observed, and insulin-like growth factor 1 IGF-1 was upregulated

See what the world looks like through the eyes of different animals. First and foremost, in order of recognized importance, is the benefit of losing body fat, especially around the middle because the more belly fat you have the lower your production of HGH.

Second, studies on fasting are very promising. In addition, intermittent fasting keeps insulin levels low because you are not bombarding your body with food, and especially sugar, every few hours.

This is a good thing because an increase in insulin caused by a surge of sugar coming into the bloodstream from the digestive tract can reduce the release of HGH. Third, exercise, and especially high-intensity exercise, has been shown to increase levels of HGH.

And fifth, follow a nutritious well-balanced diet with plenty of vegetables and fruit and high-quality protein. Autophagy is how the body recycles, breaking down older ineffective cells and salvaging pieces that are then used to produce new and more productive cells.

This is an especially important factor when it comes to aging because as you get older, autophagy decreases which can lead to more dysfunctional cells living longer.

Consider that cells in the body have a particular lifespan. For example, red blood cells live approximately days, and as they approach the limits of their lifespan, their effectiveness is reduced.

If older and less effective red blood cells can be identified sooner and dealt with, the overall productivity of the system is improved. To date, most studies on fasting and autophagy have been performed on animals and suggest that autophagy begins after about 24 hours of fasting.

More recently, with the growing popularity of intermittent fasting, there is evidence that the process may be triggered at 18 hours, suggesting that an hour fast and a 6-hour eating window may be effective in gaining cited benefits.

In other words, fasting helped turn on the production of new and more powerful immune cells. Part of this could be due to enhanced autophagy, in general, plus increased activity in the gut where some immune cells are produced.

It makes sense that if you are not bombarding your gut all day long with food, charging it to constantly digest and assimilate nutrients, it can turn its attention to other duties, like making more immune cells. While this is great news, having to fast three full days to get these immune system effects is not, because such a prolonged fast is way out of reach for most folks.

New research on intermittent fasting is encouraging because much of the effects of a three-day fast on the immune system are found with much shorter periods like the 16 to 20 hours of fasting typically associated with intermittent fasting.
