Diet for stupid humans and carnivorous animals. Not a smart choice.

@Livinlife @DelilahJones33 @girlwithsmiles Still don't know how to post links but excellent article on Healthline 'Ketosis vs. Ketoacidosis: What you should know' a medically reviewed article by Marjorie Hecht. A keto diet is not dangerous, especially with all the readily available supplements to compensate for anything you might be missing while on this diet and you can do keto without eating a lot of bacon and other high saturated fat foods! Yes this low carb diet creates ketones for energy but that is not the same as ketoacidosis which is a potentially fatal disease common with Type 1 diabetics. It is not hard on your kidneys unless you already have compromised kidney function. That myth about high protein diets blowing up your kidneys just won't go away... It's great for short term fat loss but long term is very difficult to sustain and is anti-anabolic. It can, at least at first, cause some amazingly powerful food cravings until your body adjusts to this new diet. Once you've reached your fat loss goals you can lower your fat intake and add fresh fruits and vegetables and maybe whole grains for some carbs. I have read a ketogenic diet high in fat can help epileptics but I have focused on the fat loss aspects of this diet. There were some more articles on Healthline about epilepsy and ketogenic diets.

I'm not sure what the keto diet actually is. Could you explain it to me? When I hear the name keto diet, it makes me think of ketoacidosis which is not good for you. So I must be understanding it wrong

My wife was on this for awhile; I don't think she mentioned any mood benefits. It was part of an intense workout regimen at a gym aimed at weight loss. She had to switch to something less strident due to difficulties with her back so neither the workout regime or the keto diet got a full run. Fortunately she has lost the desired weight and kept it off so clearly the keto + intense workout approach is not the only way. From her research I think she'd agree that keto is not a long term diet, and should be done under some degree of professional supervision.

I've already posted on this elsewhere. I think it's great short term. Long term be careful of kidney damage. It also sounds as if you may have been having ill effects from some foods. Perhaps if you introduce things one at a time you can work out what it was? My friend's husband felt much better after giving up gluten and so may be a small part of your diet causing the issues, not all of it. All the best.
