I second Ty Glander suggestion about Keto and Intermittent fasting. But make sure you are doing it right, eat whole, nutrient dense foods, (liver, etc.) Don't be afraid to eat animal fats. Your brain is made of fat(cholesterol), and you are what you eat. Also, a lot of people are not getting enough fat soluble vitamins, A,D,K,E, and supplements are not usually effective at supplying them. Also, look into mineral supplementation, modern agriculture is really good at depleting the soil and producing sub par food. Honestly, its not gonna work overnight and it is hard work figuring out how to implement it and fit it in with your life. I spent years trying this or that, spending who knows how much money on supplements and fancy products and they at best helped a little, but mostly there was no noticeable difference, or they had side effects. It wasn't until I started doing keto/carnivore/ intermittent fasting, that my health started to make improvements. So, check it out for yourself, everyone is different and changing your life style is hard.

Also, watch some videos on insulin resistance
I would also check out Dr. Ken Berry:

And Thomas Delauer, and Ben Azadi puts out some good information, though it is a bit heavy on the marketing:
