Doctor's Note

The reference to phytonutrients altering gut flora was an allusion to yesterday's video-of-the-day Tipping Firmicutes to Bacteroidetes. Not only is fiber also calorie-free, but one might think of it in the same snowcone "negative calorie" light, given the fermentation of fiber in our bowel into anti-obesity compounds (as well as anti-inflammatory, anti-cancer compounds). On Monday we'll continue with the obesity prevention theme with Diet vs. Exercise for Weight Loss, one of the videos I featured in my full 2012 presentation Uprooting the Leading Causes of Death.For some context, please check out my associated blog posts: The Ice Diet and Schoolchildren Should Drink More WaterIf you haven't yet, you can subscribe to my videos for free by clicking here.

    A strange hypothesis re: burning calories: 
    Wear a chilled shoulder ice wrap. Hypothetically speaking, by lowering the temperature of brown/”beige” fatty tissue located between our scapulae, one may be able to increase activity of this fatty tissue, which is brownish in color due to a high # of mitochondria. The mitochondria in these fat cells switch into high gear and burn calories to generate heat to help maintain core temperature stability.

    Uhhhh, i’ll just go out for a run instead…

      The first two times i go ice fishing i get chilled, hypothermic and unhappy.  By the third week, I feel excited, my heartbeat throbs in my fingers and toes and I become strangely invincible for many hours on the ice.  its the same every year.  Somehow, exposure turns on the brown fat and then you can litterally jump naked into ice water and like it!

        Fascinating!

    I have read that, in longevity studies on mice, a cooler body temperature induced by cooler air temperatures is an independent factor in extended lifespan. This is separate from lower body temperature that results from calorie restriction. Maybe cold drinks would have the same effect? Would make for an interesting study on mice or some other lab animal.

    I’m 55 and stopped eating meat and adopted a plant-based diet when i was 17…..thanks to this site, i’ve even stopped eating small fish, as i really did notice the difference in inflammation, which i suffer from due to back problems….i’m almost vegan but cannot declare myself as one because i still once in a while consume ghee, honey, goat and sheep cheese, and wear wool…
    i am at optimum weight. i do drink water before a meal.
    being (almost) vegan and at optimum weight, i don’t see  the need to drink or eat “ice” to burn calories, as i need all the calories i consume! Chinese medicine and nutrition warn us against eating too hot or too cold…
    Perhaps this “ice diet” would only be beneficial for those who are over-weight!

    Humans should eat what they are genetically adapted to eat.  Eskimos should eat meat and fat while Indians in the jungle should eat more plant based foods.  But guess what?  The Indians also hunt.  When you compare the SAD American diet to Vegan diets of course people are going to be slimmer.  This isn’t science.  This is picking and choosing information that support a hypothesis rather then looking for evidence that contradicts it.  Sooooo common with so called ‘nutritional science’.  Read Biochemical Individuality by Roger Williams, PhD who by the way discovered pantothenic acid.  Until you start to apply natural selection, geological and biome differences and nutritional anthropology your all going to be like a chicken with your head cut off.  TIME FOR SOME BASIC LOGIC IN MEDICINE AND NUTRITION!!!!!!!!!!!!!!!!!!!!!

      You realy think Eskimos are geneticaly adapted to eat meat? How long will it take to adapt to S.A.D.?

    The Concentration camp diet: people eating air tend to be thinner then people on the Ice Diet!  Man I’m on to something lol.

    Isn’t the reason that drinking water 20-30 minutes before a meal makes you less hungry and less likely to eat as much is because most of the time when you are “hungry” you are actually just dehydrated? Thus when you are dehydrated you think you are hungry because our bodies extract the water out of whatever food we eat. Is this not the reason drinking more water shrinks your waist line?
