Time Restricted Eating for Bipolar Depression
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether time-restricted eating (TRE) can alleviate symptoms of bipolar disorder, particularly mood disruptions. Participants will be divided into two groups: one will follow TRE by eating within a 10-hour window each day, while the other will receive nutritional counseling. The goal is to determine if TRE serves as a practical and beneficial addition to standard bipolar treatments. The trial may suit individuals diagnosed with bipolar I or II disorder who are currently experiencing depression. As an unphased trial, it provides a unique opportunity to investigate innovative approaches to managing bipolar disorder symptoms.
Do I have to stop taking my current medications for the trial?
The trial does not specify whether you need to stop taking your current medications. However, you cannot participate if you are taking stimulant medications or hypoglycemia-inducing medications.
What prior data suggests that time restricted eating is safe for individuals with bipolar disorder?
Research has shown that time-restricted eating (TRE) is generally safe and popular. In other studies, participants have tried eating within 6 to 10-hour windows, and most find it easy to follow. Although specific studies on TRE for mood disorders like bipolar disorder are lacking, it has been tested in other health areas with positive safety outcomes. TRE alters only the timing of meals, not the content, avoiding new medications or complex treatments. This simplicity makes it a promising and low-risk option to try alongside usual treatments.12345
Why are researchers excited about this trial?
Researchers are excited about time-restricted eating (TRE) for bipolar depression because it offers a novel approach that differs from traditional treatments like mood stabilizers and psychotherapy. Unlike these standard options, TRE focuses on when you eat, not just what you eat or how it's treated medically. By limiting food intake to a specific 10-hour window each day, TRE may help regulate biological rhythms and mood stability without altering medication regimens. This method is non-invasive and could offer an additional tool alongside existing treatments to improve quality of life for individuals with bipolar depression.
What evidence suggests that time restricted eating might be an effective treatment for bipolar depression?
This trial will compare time-restricted eating (TRE) with eating ad libitum for individuals with bipolar depression. Studies have shown that TRE can improve mood and reduce mood swings in people with bipolar disorder. Research suggests that TRE might help by stabilizing daily routines, which are often disrupted in those with bipolar disorder. One study found that TRE led to significant improvements in tiredness and physical health. Although specific studies on mood disorders are still underway, these early findings indicate that TRE could be a promising way to support overall well-being in bipolar disorder.12346

What Are the Treatments Tested in This Trial?
Interventions
- Time restricted eating
Trial Overview
The study compares two approaches: time-restricted eating (eating all meals within a chosen 10-hour window each day) versus regular nutritional counselling. Both groups continue their usual care for bipolar disorder over an 8-week period.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
In addition to the nutritional counselling and continuing treatment as usual outlined in Group 1, this group will be provided time restricted eating instruction. The experimental group will be instructed to select a consistent 10-h eating window between 06:00 and 19:00 for all days of the week to consume all food and beverages (except water) for the duration of the 8-week intervention. Adherence to the intervention will be monitored weekly through phone check-ins with the research assistant. At 4-weeks, the study dietician will have a 1-hour check in with participants to review progress and adherence to TRE and to address any difficulties the participants may be facing.
Participants randomized to this group will be offered nutritional counselling from a registered dietician. They will also receive a check-in from the registered dietician at week 4. They will also continue to receive treatment as usual. Treatment as usual includes pharmacological treatment options such as mood stabilizers and/or atypical antipsychotics, and psychological treatments such as psychotherapy. No current treatments will be stopped to participate in the study. We will record changes made to the doses of medications during the trial. No new treatments will be started for the duration of the trial, including pharmacological and psychological treatments
