Key Symptoms Addressed

Bipolar depression, energy impairment, and anhedonia

My Top Three Strategies

Nutritional ketosis, sleep, and light.

T
H

Therapeutic

As a researcher, I can recommend participating in a clinical trial as one excellent way to try ketogenic therapy - you'll get lots of support from a psychiatrist and dietitian, and you'll have the opportunity to contribute to scientific understanding of the condition. Therapeutic ketosis is very different to the popular versions of the ketogenic diet you can find online, and this is best done with the proper support. There are now many clinical trials taking place worldwide, you can find these listed on the Metabolic Mind website. We will begin recruitment for an RCT in the UK in 2026, please do get in touch if you would like to learn more about the trial.

I

Integration

A few things I have found helpful in maintaining ketosis:C8 MCT oil (occasionally as needed), ketone salts, intermittent fasting (one meal a day). 10k steps per day has also been very helpful in controlling my blood glucose.

N

Nutritional

  • I tend to eat more animal-based fats on a ketogenic diet, which I find work best for me personally in terms of satiety and maintaining ketosis. But there are many variations like vegetarian and vegan versions of the ketogenic diet, which also achieve ketosis.
  • I generally feel best when I fast until dinner and eat one meal for dinner. This allows me to get into higher levels of ketosis. I listen to how my body feels each day and will add in breakfast and/or lunch as needed.

K

Ketosis

  • Ketosis is not the result of a "fad diet” as you will sometimes hear online, it's an ancient biological state which has been around for millions of years across diverse forms of life. It's been an essential state of human physiology for survival, allowing humans to tap into fat resources when carbohydrates are scarce. Humans can store around 25000 calories from carbohydrate as glycogen and well in excess of 100,000 as fat. So ketosis is really an essential mode of human metabolism.
  • What's fascinating about ketosis as someone living with bipolar, is the effects it has on the brain: reducing hyperexcitability, reducing glutamate levels (an excitatory neurotransmitter and neurometabolite), fighting inflammation and ameliorating seizures in epilepsy. Several important medications for bipolar were originally developed for epilepsy, and we are just beginning to learn about the broad range of effects ketosis has on the brain in bipolar disorder. Our pilot study showed significantly reduced glutamate levels in bipolar patients after a 6-8 week ketogenic diet.

S

Sleep

Your circadian and metabolic systems are ancient survival systems that are very closely linked. And the mechanisms underpinning these play central roles in bipolar disorder. I think that bipolar depression is, in part, an example of physiology being locked into a broken energy-conservation and survival mode. I try to give my body clear signals that it needs to activate metabolism and restore normal energy. I do this by getting bright sunlight in the morning, which signals to my circadian system to tune up metabolism (20 mins of sun exposure walking part of the way to work). Getting to sleep before 11pm at the latest also greatly helps to synchronise circadian rhythms. I reduce artificial light at night (particularly blue light) which has been shown to be associated with bipolar disorder and use incandescent bulbs or candles where possible. And I occasionally use a bright light in the early afternoon in winter.

M

Move

  • Living with bipolar type 2, I find that my body needs very clear signals to increase my metabolic function to the right level and avoid depression. One of these signals is exercise. I do a 20 minute run or longer walk outside in the sunlight most mornings and I can feel a benefit for several hours afterward.
  • I like weight-lifting as I find it very calming and having more muscle mass acts as a metabolic sink for glucose in the body. Although intense exercise can temporarily spoke glucose and reduce ketones, I find that this only lasts a short amount of time and I feel better than I would have done when my glucose comes back down.

A

Avoid

Living with bipolar disorder, I need to give my brain every advantage possible to be resilient. I rarely consume alcohol and I feel best when I don't drink at all.

R

Rebuild

I think if you're stable with bipolar, life should be an exciting and meaningful journey. You have unique and valuable perspectives on the world, many bipolar people are very creative and have a naturally compassionate nature. You have unique contributions to make in the world, and there are so many examples of bipolar people who have done so before. I recommend engaging with any activities which help you reach a flow-state, this is what peak healthy brain function feels like to me. After having a malfunctioning brain for so long, I enjoy the journey of seeing what it can do when functioning well. I like writing cinematic music with my wife (we write under the name "Ex Makina") and writing scientific papers on topics I'm fascinated by.

T

Track

  • I found it very useful when beginning a ketogenic diet to track ketone and glucose levels daily. This gave me an intuitive feel for what factors affected my ketone levels the most. As I learned this, I began to track less often having learnt what works and what doesn't. Personally, a higher range of 1.5 - 2 mmol/L has been more helpful for reducing my symptoms.
  • I also think having a food diary is quite helpful. I use an app called MyFitness Pal to log what I eat. I've recently started working with a personal trainer and it's really helpful to have an accountability partner who you can share your food diary with.
  • I use an Oura ring for sleep tracking. Studies show that bipolar sleep is often fragmented, you don’t always progress smoothly through the sleep stages from light to deep and back, but rather the bipolar person jumps between these. Using a tracker can help you to see this and take sleep hygeine measure to improve your sleep quality.
