(Online Study) Healthy Lifestyles for Bipolar Disorder
(HL Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how two different healthy eating plans—time-restricted eating and the Mediterranean diet—affect people with bipolar disorder who are already on medication. Researchers aim to determine how these diets influence mood symptoms and overall quality of life. Participants will track their eating, sleep, and mood for two weeks, then follow one of the diets for eight weeks. This trial suits individuals with bipolar I or II disorder who have sleep concerns and are currently stable on their medication. As an unphased trial, it offers a unique opportunity to contribute to understanding how diet can improve life quality for those with bipolar disorder.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but it does require that your mood-stabilizing medication regimen has been stable for at least one month. Some medications that are contraindicated (not recommended) for fasting, like clozapine and certain diabetes medications, may affect eligibility.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that both the Mediterranean diet and time-restricted eating (TRE) are safe and easy to follow. Studies have found that the Mediterranean diet, which emphasizes fruits, vegetables, whole grains, and healthy fats, can improve heart health and lower the risk of some cancers.
Time-restricted eating, which involves eating only during certain hours each day, is also generally safe. It can enhance metabolism and mood, and many people find it easy to maintain.
Overall, both diets have been studied and found to be safe with positive health benefits. Participants in these studies did not report major issues, making them promising options to consider.12345Why are researchers excited about this trial?
Researchers are excited about exploring healthy lifestyle changes like the Mediterranean diet and Time Restricted Eating (TRE) for managing bipolar disorder because they offer a non-pharmacological approach that could complement existing treatments like mood stabilizers and antipsychotics. Unlike the standard medications, which focus on altering brain chemistry, these lifestyle interventions aim to improve overall well-being through natural methods. The Mediterranean diet emphasizes nutrient-rich foods that support brain health, while TRE encourages better eating habits by limiting eating hours, potentially stabilizing mood and energy levels. Together, they represent a promising shift towards holistic management of bipolar disorder, which could enhance quality of life without the side effects often associated with medication.
What evidence suggests that this trial's treatments could be effective for bipolar disorder?
This trial will compare the Mediterranean diet and Time-Restricted Eating (TRE) as interventions for bipolar disorder. Research has shown that the Mediterranean diet, which participants in this trial may follow, can help reduce symptoms of mood disorders, such as bipolar disorder. This diet includes plenty of fruits, vegetables, whole grains, and lean proteins, and it can improve mental health by reducing depression and anxiety. It is also linked to a better overall quality of life.
Time-restricted eating (TRE), another intervention in this trial, involves consuming all meals within a specific 10-hour window each day. Early evidence suggests that TRE can benefit mood and metabolic health. Studies indicate that TRE can help regulate the body's internal clock, which might improve mood stability for people with bipolar disorder. Both the Mediterranean diet and TRE offer promising ways to manage symptoms alongside medication.12678Who Is on the Research Team?

Experimental Treatment
Active Control
Participants will receive an intro to TRE and then throughout 8 weeks they will receive brief online psychoeducation several times per week with optional weekly coaching sessions. TRE involves restricting the window of eating to 10 hours/ day, most typically by avoiding eating in the first 1-2 hours after awakening and in the 2-4 before sleep. Those with an eating window \> 14 hours will be asked to restrict their eating to 12 hours in the first week, then 10 hours in week 2. To select the period, investigators will ask Ss to review baseline logs to consider sleep, eating, family meals and social commitment schedules, and any special energy demands, such as exercise. During the eating window, no restrictions are placed on the type or quantity of food consumed. The investigators will instruct participants to follow their habitual diet within their 10-hour eating window and to aim to consume the same number of calories per day as they did at baseline.
Participants will receive a several page introduction to the mediterranean diet, and then will receive support throughout the 8 week intervention to follow this food plan, including brief online psychoeducation that will be sent several times per week, and optional weekly coaching sessions. The mediterranean diet is a plan for healthy eating based on how people eat in the mediterranean region. Individuals will be encouraged to consume vegetables (6 servings/day), fruits (2-4 servings/day), whole grains (daily), legumes (3-4 times per week), nuts (.5 oz per day), and oily fish (2 servings/week). Participants will be encouraged to choose lean meats and other sources of protein over red meat and processed meats. Sweets, refined cereals, alcohol, and wine or alcohol will be labelled as extras, and participants will be encouraged to limit consumption of extras.
