Hello and thank you for such an informative site.
A low carb diet/lifestyle is so opposite to the things we have been taught. I am grateful for the clear descriptions of the physiology of how and why LC works.
I am 10 days in (and have lost 7 pounds) on my LC diet with a goal of losing 40 pounds. Once I got past the first 3 days of transition it has been easy.
It has been a pleasure reading the posts and I am sure it will be a source of reassurance as I progress.
Thanks again
J

My pleasure.

When your body is in the state of ketosis does it have any negative effects on the kidney and liver or any other organs?

No, not if it’s normal ketosis such as that produced by fasting or a low-carb diet.

I do agree that this discussion belongs elsewhere. But I don’t need it. It’s just that Sandi Penn tried to turn it into a religious one and I couldn’t help but react. Using the phrase ‘those of us who know’ is arrogant. Guess that’s what triggered me. Sorry.

“I do not believe we evolved. The body is a wonderfully designed machine. It�s no wonder then, to those of us who know there IS a God, that ketosis exists.” (Sandi Penn)

Ketosis exists in ALL creatures’ bodies that have a brain, heart, liver and blood–it is NOT a strictly human condition. That said, this discussion belongs elsewhere…Andre.(Mr. War, disease and human suffering)

War, disease and human suffering are terrible. It’s no wonder then, to those of us who suffered disease or the loss of loved ones, know that there is either no god at all or a god that is vicious and cynical. Let’s face it; we are on our own. Nobody other than us look after us. The universe is a very hostile environment, never meant for life. Life on earth is a happy accident. Unintended, but great. Just enjoy the ride.

Hello Dr, Is there a calculation that i can use to see how many calories i need to create a calorie deficit so stored fat is used for energy? Thanks for your time There are many calorie counters on the web. Here's one that looks pretty good. Just give it the info it asks for and calculate. Reduce calories from there.

hi dr

Again just wanted to say thanks for this post, I have read it all,
I just wanted to know, is high fat needed to enter ketosis?? For
Example eating a low/ no carb diet with average fat?? Or is more
Dierty fat needed?
Also if I did calorie cycling, would that stop my metabolisming
Dropping on low calorie & low carb together??

Thanks again

Tundet

A lowered carb intake (or fasting) is what it takes to get into ketosis. If you eat a ton of fat along with a lot of carb, you won’t get into ketosis. The restriction of carbs is more important than the amount of fat.

Dr. Eades,

Very good post. But I am having trouble with the ketosis Math.

If an average person requires about 200 grams of glucose per day to meet all his needs. And if, after ketosis, this requirement drops to 130g grams of glucose per day. We can conclude that the ketones replace 70 grams of carbohydrate (or 280 calories) per day. Is that correct?

That’s pretty much correct.
