Dr. Ted Naiman: Ketosis and a diet rich in protein

10,805 views Add as favorite
How does an increased protein intake on low carb work with still being in ketosis – and what does the latest research have to say about it?

A highly debated topic at the moment and one of the high-protein diet promoters is Dr. Ted Naiman. In this presentation from the 2018 Low Carb Cruise, he talks about the basis of his standpoint: that the amount of protein consumed impacts energy intake.

    So the old Atkins or new Atkins is keto with higher protein. I’ve lost 65+ pounds over 4 years doing low carb. I’m 73 and feel the low carb works for me.

    Ok, you can eat bunch of protein and stay in ketosis, but do you know that glucose is not the only thing in the body?
    Excess methionine depletes essential methylation nutrients that are used up for recycling of toxic homocysteine.
    Excess leucine which acts like oxidant, suppress mTOR and rises IGF-1. May lead to liver and brain damage.
    Also studies show that protein restriction equals most benefits of calorie restriction and fasting. It can extend lifespan of fruitflies up to 67% and rats up to 40%.
    Protein need to be balanced with methylation nutrients.

    What I got from Dr Rosedale who was one of the very first lowcarb proponents is that proteins speed aging. Like FC mentions. So while it helps limit your calorie intake now it also limits your life. Didn't yet watch the interview and wonder if he is aware of this little known fact from ageing research.

    I have cut down on meat a lot and am eating a lot of veggies. Been going on for two weeks. And am feeling a lot stronger and flexible. Oil and fat intake is still high.

    To much protein for dinner caused me to have delayed glucose levels. My levels increased throughout the day. After 17 hours of intermittent fasting it would finally go down. Not sure why it happens. But when I eat closer to 60 grams of protein my glucose levels didn't go as high during the day.

    Great article! Protein should always be the focus when going low carb or keto, especially for weight loss specifically.
