What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores whether an 8-week routine of fasting for 14+ hours nightly (known as Prolonged Nightly Fasting) can reduce pain and improve mood, sleep, and inflammation in people with fibromyalgia. Participants will be divided into two groups: one will follow the fasting routine, while the other will watch short health education videos weekly. Women diagnosed with fibromyalgia who own a smartphone might be a good fit for this study.

As an unphased study, this trial offers participants the chance to contribute to innovative research that could lead to new insights and potential treatments for fibromyalgia.

Do I have to stop taking my current medications for the trial?

The trial requires that you stop taking melatonin or any immunosuppressant medications (like steroids) if you are currently using them.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that prolonged nightly fasting (PNF) might be safe for people with fibromyalgia. One study during Ramadan, a month of fasting, reported no serious side effects. Another study found that patients with fibromyalgia experienced no major problems while fasting in a hospital. These findings suggest that PNF might be well-tolerated by those with fibromyalgia. However, as this is an early trial, further research is needed to confirm these results. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Prolonged Nightly Fasting (PNF) is unique because it explores a dietary approach rather than relying on medications like antidepressants or anticonvulsants, which are common treatments for fibromyalgia. Unlike these standard treatments, PNF involves fasting for 14 or more hours each night, which may help reduce inflammation and improve pain management by giving the body a longer rest period to reset. Researchers are excited about this method because it could offer a non-pharmaceutical option with potentially fewer side effects, providing a new avenue for managing fibromyalgia symptoms.

What evidence suggests that this trial's treatments could be effective for fibromyalgia?

This trial will compare Prolonged Nightly Fasting (PNF) with a Health Education Control (HEC) for fibromyalgia. Research has shown that longer periods without food at night might improve symptoms for people with fibromyalgia. Studies have found that skipping meals or fasting can relieve symptoms. In one study, patients reported no serious side effects from fasting, suggesting it is safe. While more research is needed, these early findings suggest that fasting at night could help improve pain and mood in fibromyalgia patients. ^{1 2 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Prolonged Nightly Fasting

Trial Overview

The study tests if not eating for an extended time each night (Prolonged Nightly Fasting) for 8 weeks can help reduce pain and improve mood and sleep in people with fibromyalgia. Half of the participants will follow this fasting routine while the other half will receive health education as a control.

How Is the Trial Designed?

Group I: Prolonged Nightly Fasting (PNF) Experimental Treatment 1 Intervention

Participants will engage in the PNF (14+ hours a night of fasting and no calorie containing food or beverages) for 8 weeks.

Group II: Health Education Control (HEC) Active Control 1 Intervention

Participants in HEC group will receive weekly 15-minute videos (once weekly) focused on non-diet/non-fasting health educational content for 8 weeks.

Published Research Related to This Trial

In an 8-week study with 59 obese participants, alternate day fasting (ADF) led to a significant weight loss of 4.2%, while only a small percentage reported mild adverse effects like constipation and dizziness.

ADF was associated with improvements in eating disorder symptoms, including a decrease in depression and binge eating, suggesting that it may have beneficial effects on body image and eating behaviors.

A study is being conducted to explore the effects of alternate day fasting (ADF) on healthy non-obese individuals, involving 90 participants, with some having followed ADF for at least 6 months and others starting ADF for 4 weeks.

The research aims to assess various health parameters, including metabolic and cardiovascular effects, using advanced techniques like echocardiography and glucose monitoring, to better understand the physiological impacts of ADF.

Fasting therapy, a well-established treatment in Europe, has shown significant benefits for chronic diseases, particularly rheumatic diseases, and is supported by updated guidelines from an expert panel.

Recent studies suggest that fasting may also help with other conditions like metabolic diseases, pain syndromes, and chronic inflammation, but it must be conducted under the supervision of trained healthcare professionals to ensure safety and effectiveness.

Intermittent fasting, including methods like the 5:2 diet and time-restricted feeding, shows similar weight loss efficacy to standard daily calorie restriction, but many fasting models do not involve strict fasting cycles or complete fasting.

Longer fasting durations, particularly those extending beyond 16 hours, may enhance benefits like fat loss and improved insulin sensitivity, suggesting that the physiological effects of fasting could be more pronounced with sustained fasting periods.

A pilot study involving 48 patients with fibromyalgia found that a multimodal Integrative Medicine (IM) approach, which included fasting therapy, led to significant short-term improvements in fibromyalgia symptoms compared to a conventional rheumatology (CM) approach after 2 weeks.

While the IM approach showed benefits in reducing symptoms like pain and anxiety initially, these effects diminished after 12 weeks, suggesting that while IM may be effective in the short term, further research is needed to evaluate its long-term efficacy.

Intermittent fasting (IF) has been shown to result in weight loss ranging from 0.8% to 13.0% of baseline weight across 27 trials, with no serious adverse events reported, indicating it is a safe option for treating obesity.

When compared to traditional calorie-restricted diets, IF produced equivalent weight loss results, and it also improved glycemic control in patients with type 2 diabetes, suggesting its potential effectiveness in managing obesity and related metabolic issues.

Intermittent fasting, involving 12 to 16 hours of energy intake restriction, shows promising health benefits that could be particularly useful in managing chronic pain, as suggested by a literature review of various studies.

The review highlights the physiological effects of intermittent fasting and its potential mechanisms for alleviating chronic pain, indicating a need for further research to explore its clinical applications.

Women with fibromyalgia (FM) exhibited significantly higher rates of emotional eating and concerns about eating, shape, and weight compared to healthy controls, indicating a potential link between FM and disordered eating behaviors.

In the FM group, higher hunger levels were associated with lower serum levels of brain-derived neurotrophic factor (BDNF) and higher levels of S100 calcium-binding protein B (S100B), suggesting that these biomarkers may play a role in the altered hunger and satiety perceptions in FM.

Medically supervised modified fasting (200-500 kcal/day) for 7 to 21 days has shown efficacy in treating rheumatic diseases and chronic pain, with participants often experiencing improved mood and alertness.

Fasting may enhance mood and reduce pain through increased brain levels of serotonin, opioids, and endocannabinoids, along with neuroendocrine activation, suggesting it could be a valuable adjunctive therapy for chronic pain patients.

In a study of 22 women with fibromyalgia, a Mediterranean diet enriched with tryptophan and magnesium significantly reduced symptoms of anxiety, mood disturbances, eating disorders, and dissatisfaction with body image after 16 weeks.

Despite the positive effects on psychological variables, the enriched diet did not lead to improvements in sleep quality, indicating that while it may help with mental health, it may not address all aspects of fibromyalgia symptoms.

Dietary interventions, such as hypocaloric, raw vegetarian, and low FODMAPs diets, show promise in improving pain and functional outcomes in patients with fibromyalgia, with 5 out of 7 studies reporting positive results.

Despite these promising findings, the overall quality of the studies is low, indicating a need for better-designed research to conclusively determine the effects of dietary interventions on fibromyalgia symptoms.
