New Bipolar Disorder Research Study: Join Today!

We have just launched the largest study ever conducted on how dietary interventions, when added to medication, might help sleep issues for people with bipolar disorder.

Our goal is to understand not only if the intervention helps, but also a very broad range of the ways in which it may help, including when it helps and when it does not help. We’re looking for people who will help us understand this important set of goals, by sharing their experiences with us through a very broad range of questions, as they try on one of our dietary interventions. This study will involve many, many different questions because we sincerely want to deeply understand each person’s experience during this study. 

This study will compare the benefits of two approaches to eating: Time-Restricted Eating and the Mediterranean Diet. Neither food plan is meant to be a diet or a treatment. In this study, we ask you to consume the same amount of food that you normally would and to continue your regular medical care for bipolar disorder. We would assign you to one of these food plans.

There are two versions of this study: a local version, and an international version. Those who live close to Berkeley, CA who might be willing to periodically visit a a locally convenient lab to get blood work done might participate in the local study, while those further from the Bay Area might participate in our entirely-remote international study.

Time-Restricted Eating with Bipolar Disorder

Time restricted eating involves restricting eating to 10 hours per day. To make that happen, people typically avoid eating in the first hour after they wake up and avoid eating in the couple hours before they go to sleep. To do this, you’d need a standard schedule that works well for you, and we’d work with you to determine that window.

TRE has been shown to improve sleep and circadian rhythms, and we would like to understand if it similarly has this benefit in symptoms of bipolar disorder.

The Mediterranean Diet with Bipolar Disorder

The Mediterranean Diet is one of the best studied ways to eat healthfully. It is based on the typical diet in the 16 countries surrounding the Mediterranean sea, and it involves eating more fruit, vegetables, whole grains and legumes, and using olive oil in place of less healthy fats.

This diet has shown to be significantly beneficial for people with heart disease, diabetes, and a number of other health conditions.

We would like to understand if the Mediterranean Diet also has benefits for symptoms of bipolar disorder.

In the study, you would be asked to log your regular eating habits for 2 weeks, while we share tips about healthy sleep and goal-setting with you. Then, we would assign you to follow either Time-Restricted Eating or the Mediterranean Diet. At this point, we would share initial instructions and tips to follow your food plan, and you would continue to receive more tips about healthy eating and sleep throughout the 8 weeks of following the plan. Throughout this time, we’d have you log your food daily, in order to see how the food plans are working for you. Multiple times throughout the study, we’d also ask you to take paid surveys or interviews so we can track how things are going.

This study has officially launched. We sincerely hope you’ll be interested in working with us. If you are interested in participating in this study, please fill out the following survey:
