I am a patient on this site-but I have a master's in nutrition. We don't recommend keto diet to people (kids with seizures are an exception)-all the protein is hard on the kidneys, all the fat is hard on the liver and it can also increase the cholesterol.

That being said, some have found it very helpful for weight loss without the effects I have mentioned-over time, the risk increases of said effects.

If you're looking at diet for weight loss, Mediterranean diet is wonderful for that. Mediterranean diet can help a variety of things-diabetes, cholesterol, it's even been shown to help depression.

Best of luck to you!
