    So would his theory confirm that cow belching does not contribute to climate change because it is new carbon not old like in fossil fuels?

      Agree, people who sing in the climate change chorus, will be abhorred to know they're emitting CO2.

    13:05 "I am a physicist" then you should know that E=mc^2 says that matter can be converted into energy.

  • Dan Hutchinson
    Dan Hutchinson 16 days ago

    Keto is a low Carbohydrate diet..you had it right the first time and then began saying low Protein....and from what I've just heard 21 minutes in, Is no, you don't know anything about Keto. Your liver is on the right side of your body FYI, not the left side.....The liver breaks down acetone to chemicals that are not harmful. The body uses these chemical to make glucose (sugar) and fats that make energy for normal body functions. The breakdown of sugar for energy makes carbon dioxide that leaves your body in the air you breathe out. These are normal processes in the body. Your body can not make Acetone in huge quantities....You really should stick to talking about subjects you know something about......Now I feel that I can not believe ANYTHING you have said and I have wasted 21 minutes (plus 4 for this comment) of my life....

    What a wonderful speaker. Excellent topic of great interest to all of us (I think). Personally? I have discovered that we cannot "kickback", relax, sleep, and wait for the weight to disappear. Weight loss takes MOVEMENT (bodies in motion are how to stay thin and fit:-)

  • Melons1054

    I worked in healthcare. People overeat because they are legitimately hungry and food is available. The only thing I've seen that works is when someone experienced liver damage. The circulating liver enzymes caused anorexia. If we could mimic that, the brain would shut down the appetite.

    To make this easier for me to remember I think I'll call eating less dieting...
    And the moving more, um, I'll call exercise...
    And maybe I'll call the keep breathing part living...

    So the breakthrough discovery is that dieting, and exercise and apparently living equals weight loss...
    *Mind blown*

    Just FYI, at 20:45 (and again at 20:58 ) I think he had a slip of the tongue and meant to say low carb diet not low protein diet.

    This is why I get slightly irritated at magazines etc that overcomplicates the idea of weigh loss with the millions of different diets and methods. It really is as simple as "calories in, calories out", just eat less (and better foods) and move more (not really important what kind of exercises you do, just move). If you consume more energy than you get rid of you will gain weigh, and vice versa for losing weigh.

  • Ja3 sk3adik
    Ja3 sk3adik 27 days ago

    It's interesting but I think it is more complex than eat less move more. I have hypothyroidism, I naturally eat less but even when I move more i still gain weight and as a result will have to be very particular of what I eat.
