NCT07140289
This study aims to assess the effect of using Glucagon-like peptide-1 receptor agonists (GLP-1) receptor agonists on gastric emptying on surgical patients and whether specific guidelines need to be established for these patients. GLP-1 receptor agonists are mainly used for the treatment and mitigation of obesity and metabolic syndromes. One of their mechanisms of action is by delaying gastric emptying, hence increasing satiety. However, patients need to abstain from eating for a set amount of time before surgery to reduce the risk of aspiration. Hence patients who use GLP-1 receptor agonists may need more time to abstain eating (nil-per-os). In this study we aim to assess how much time is sufficient before surgery in these specific population of patients.

This study aims to evaluate the efficiency of intermittent enteral nutrition versus continuous enteral nutrition to prevent from organ failures for patients at the acute phase of sepsis shock with mechanical ventilation in ICU.
NCT07001358
The body's systems are deeply connected, but they are often studied separately. A recent large-scale citizen-science project on women's health, called Isala, discovered a group of gut-related bacteria present in the vaginal microbiome. This finding supports the idea that gut and vaginal bacteria interact closely, a connection known as the gut-vagina axis. However, it remains unclear whether changes in gut bacteria influence the vaginal microbiome. This discovery led to an exploration of how diet affects both the gut and vaginal microbiomes. In the gut, bacteria rely on carbohydrates from food, while in the vagina, bacteria feed on glycogen, a sugar stored in the vaginal lining. This glycogen is broken down into smaller sugars, which beneficial Lactobacillus bacteria use for fermentation. Since starch is a major source of these sugars, researchers suspect that a starch-rich diet may support Lactobacillus growth, which in turn promotes vaginal health. To test this hypothesis, the Rufaida Project was launched. Ramadan is characterised by a fasting period of approximately one month during which participants abstain from eating between sunrise and sunset. Ramadan provides a unique opportunity to study how fasting affects the microbiome under controlled conditions. In this study, 50 Muslim women will be asked to provide vaginal and stool samples at eight predetermined time points-before, during, and after Ramadan. These samples will be analysed using 16S rRNA amplicon sequencing to determine bacterial composition. Comparative analysis will be conducted between samples across different time points and anatomical sites. The objective is to understand how fasting and dietary changes influence the gut and vaginal microbiomes, and whether gut bacteria play a role in shaping vaginal health. Additionally, participants will complete weekly health questionnaires. An additional study group of up to 300 Muslim women will complete weekly questionnaires without providing biological samples. This research could improve understanding of the links between diet, gut health, and vaginal health, potentially leading to new strategies for enhancing women's well-being through nutrition.
NCT06299020
In primary adrenal insufficiency, there is an increased risk of hypoglycaemia and dehydration. These risks have been little studied particularly during intermittent fasting. The present study aimed to assess these risks in a prospective study of 30 subjects with primary adrenal insufficiency. Patients will undergo a clinical examination, blood sampling and continuous glucose monitoring for fourteen days (one week of fasting and one week of non-fasting).
NCT06804044
The goal of this clinical trial is to learn if dietary interventions works to improve anthropometric measures in women with PCOS. The main questions it aims to answer are: * Does intermittent fasting (IF) cause loss of body weight, fat and muscle mass? * Can IF be considered more effective to medical and standart nutrition therapy (SDT)? * What dietary problems do participants have when having IF diet? Participants will: * Follow IF, SDT, or no intervention for 8 weeks. * Visit the clinic once every 2 weeks for check ups with a total of 5 visits for intervention groups IF and STD, visit at the beginning, second week and at the end for control group * Keep dietary records
NCT05760339
The purpose of this study is to investigate whether time-restricted feeding, a form of intermittent fasting, before surgery improves insulin resistance around the time of surgery, compared to carbohydrate drinks and standard fasting before surgery.
NCT05136313
Obesity-related cardiometabolic diseases are now a leading cause of death worldwide. These diseases result from a dysfunctional adipose tissue (AT) that induces inflammation, insulin resistance and altered endocrine function. However, not all obese people develop metabolic complications, which has given rise to the concept of "metabolically healthy obesity" (MHO). Recent evidence suggests that intermittent fasting methods, in particular time-restricted eating (TRE) may be effective in improving cardiometabolic health, independently of weight loss, and this could be particularly effective in MUO subjects. The investigators hypothesize that in young male adults TRE is a more effective/beneficial approach in MUO than in MHO due to the weight loss-independent improvement in their inflammatory and metabolic derangements. To this aim, a 16-week 8h TRE intervention study will be performed in MHO and MUO subjects, assessing anthropometric, endocrine, and other outcomes.

Type 2 diabetes (T2D) mellitus is a challenge for health care systems as the numbers increases constantly. In 2014, 422 million people had been living with diabetes worldwide. The absolute numbers of people with prediabetes have also grown substantially over 25 years worldwide. In Germany, about 10% of the population has T2D and another 21 % of the population has prediabetes.Overall, 16% of all deaths in Germany are attributable to type 2 diabetes. Macro- and microvascular complications of diabetes imply a significant threat for the patients and are already present in the prediabetic state. Short term and long term complications, the burden of treatment, and reduced quality of life are major burdens of the disease. Accumulating data indicate that currently recommended therapeutic diet regimens in patients with obesity and diabetes are not sustainable on the long term. Novel concepts are therefore urgently needed. T2D occurs when insulin secretion from pancreatic beta-cells cannot sufficiently be increased to compensate for insulin resistance. Causes of beta-cell dysfunction are heterogeneous. In addition, the most important determinants of diabetes remission are the extend of weight loss and restoration of beta-cell function. In the course of diabetes progression, the inability to recover insulin secretion might identify the state of no return to normal glucose tolerance. It is therefore crucial to improve insulin secretion in treatment and prevention of diabetes. Up to now lifestyle intervention trials in prediabetes or pharmacological intervention trials in diabetes did not show improvement of insulin secretion after intervention. However, one recent small human trial shows that intermittent fasting (early time restricted fasting) is able to improve insulin secretion.Currently, there are no trials that examine the effect of intermittent fasting in individuals with a broad range of impaired glucose metabolism (from prediabetes to diabetes). Recently novel subtypes of diabetes and prediabetes with high risk for the early manifestation of diabetes complications have been identified. Currently, prevention strategies for this high risk individuals have not been examined yet. We will study for the first time the effectiveness of 4 weeks intermittent fasting on changes in insulin secretion capacity in subphenotypes of diabetes and in prediabetes.
NCT05678426
The goal of this clinical study is to learn about disease-risk and age-associated changes in DNA methylation patterns associated with disease risk or age in healthy women aged 30-60 in response to health-promoting lifestyle intervention (intermittent fasting or smoking cessation). The main questions the study aims to answer are: * Are the scores of DNA methylation in epigenetic signatures associated with age, women's cancer risk, or risk exposure reduced after 6 months of lifestyle intervention compared to baseline? * What are the dynamics of DNA methylation changes during or following intervention, and do differences in changes between different sample types exist? * Which other biomarkers of health and disease, including metabolic changes, microbiome, clinical, mental, or inflammatory parameters, are altered following intervention? The investigators also aim to explore whether DNA methylation changes are associated with changes in other biomarkers mentioned above. Participants will be allocated to intermittent fasting or smoking cessation based on inclusion criteria. Intermittent fasting encompasses a 16:8 intermittent fasting schedule. Food intake is limited to an 8 h window per day with fasting for the remaining 16 h. Within the intermittent fasting study, participants are randomised to receive a ketogenic supplement (medium-chain triglyceride fibre) or not. Participants in the smoking cessation study will be guided to stop smoking. All participants will receive 1:1 personal coaching throughout the study, and will be provided with an optional exercise programme. All participants will also receive nutritional advice from a professional dietician throughout the study. Participants are invited to donate samples every 2 months for 6 months. Researchers will compare signatures at the start and after 6 months of intervention. Within the intermittent fasting group, researchers will compare effects in individuals that received the ketogenic supplement to those that did not.

Obesity presents a substantial economic burden in Jordan. Binge eating disorder (BED) and food addiction (FA) are the most common eating disorders associated with obesity. BED and FA most therapeutic approach is cognitive-behavioral therapy. Dopamine (DA) and serotonin (5HT) the major neurotransmitter responsible for FA and BED. Daily calorie restriction (CR) and intermittent calorie restriction (ICR) are two forms of diet therapy that can help weight loss. Prolong fasting increases lipolysis and elevates ketones bodies' levels in the brain led to a significant increase in the DA and 5HT. No prior human research has examined the effect of ICR (model 8:16) on DA and 5HT levels and weight reduction on obese with BED and FA. Therefore, A Randomized, controlled trial of 6 weeks follow-up will be used. A sample of 100 obese women will be selected to be randomly assigned to daily CR or ICR, or control group without FA or BED for a period of 6 weeks. Participants will be undergoing nutrition assessment, Anthropometrics assessment, food Addiction assessment (YFAS), binge eating assessment (BEDS-7), and hormonal level (DA\&5HT) at baseline and after 6 weeks. The investigators anticipated that CR and ICR (model8:16) will significantly induce DA\&5HT level changes and that ICR (model8:16) will be significantly more effective than CR in reducing BED \& FA.

This randomized controlled clinical trial will assess the impact of intermittent fasting on the incidence of gestational DM in obese pregnant women in 3rd trimester and its effect on maternal and neonatal outcomes.
NCT04404413
The objective of this study is to compare the body composition and physical performance effects of HIIT, with or without intermittent fasting intervention in active women. Fourteen active normal weight women aged 18-35 participated in the study. The effects of 2x8 weeks without (HIIT) or with (HIIT+IF) intermittent fasting caloric restriction (20% reduction in weekly energy intake) on body composition and performance (Hand-grip strength, Counter movement jump, Wingate Anaerobic 30 s Cycling Test), were compared. There were two weeks in between both phases when they did not perform the scheduled activity, so as not to alter the experimental phase.
