The ketogenic diet is not necessarily ideal for TBI. If you want the MCT's that are part of the ketogenic diet, consume unprocessed coconut oil. The ketogenic diet is high in Medium Chain Triglyceride that provide a good source of ketone production. Those who have improper processing of Long Chain Triglycerides / blood glucose will benefit from MCT's. If there is not a problem metabolizing LCT's / glucose, the ketone diet is overkill.

You will not find that magic pill for your concussion. It will take a discipline to reduce stress in your life. Looking for that magic pill is too stressful. Researching every possible treatment, most that have limited application, is likely raising your stress level so you do not get a chance to get the quiet rest you need. Wait for the top notch doctors that you have access to as they offer slow ways to improve.

Your job already has far more stress than your brain needs at this point.

Learn to use work-arounds to get your day done without the stress. It will pay big rewards.

If you are attempting to avoid fats, it may be a problem. You brain needs animal fats. The fats in most chicken are based on diets that are not natural. Corn fed beef has un-natural fats. If you can find grass fed beef, it will be the best for you. We used to pay extra for a natural chicken from a Colorado Farm at the butcher shop. Race Street likely has the natural fed chicken. Maybe even Trader Joe's. Don't cook the fat out of it. Or save the drippings and make a nice gravy or broth.

My best to you.
