    His comments about climate change are incorrect (burning fossil fuels does release carbon dioxide into the atmosphere which results in climate change) but the other stuff is correct.

    He should have just stuck to the Chemistry stuff. Ketoacidosis is not the same thing as being in nutritional ketosis. I'll give him a pass on the rest of the incorrect information he stated because this video was posted in 2013 and they didn't have as much info back then :)

      Infact it doesn't work xD
      Eating correctly is much more important than eating less.
      If you eat raw food it's harder to digest and it takes more calories too, which means eating raw food is better if you wanna lose weight.
      There is plenty of things to take into account.
      Eat less and move more is generally speaking correct, but there is hundreds of more important factors that would make eating less and moving more just painful activity with no good results

    Great video; however, what he gains in chemical understanding, he lacks in nutritional understanding. "Eat less, move more, and breath" is not all you have to do to lose weight -- at least not if you want to lose weight and be healthy. Having said that, I learned something and loved the video.

  • Nunya Bizness

    At 20:46, I think he meant to say "low carbohydrate, high protein," instead of "low protein." A ketogenic diet is low carbohydrate, not low protein. HTH.

    • Andy ARGON
      Andy ARGON Day ago

      I was thinking the same thing. I lost 30 lbs on the keto diet I felt great the first 2 weeks. I actually started feeling a bit negative after that then again I was cutting out almost all carbs. I would like to know more on the effects of ketosis to the body.

      yes but no. the equation is true but only applies to matter in very abstract physics. Therefore, for normal use conservation of mass is adequate, but conservation of energy would be more adequate.

    This is very interesting to me. As a side story, my family and I recently visited the Colorado Rockies (11,000+ ft.).
    Now the 1st day of the trip was spent at around 6000 feet. and I was surprised that I had forgot about the lack of oxygen I might encounter at high elevations, being from Fa.
    It had been 20+ years since I had been in Colorado and the one thing I forgot about was elevation and the breathing issues.
    But luckily my wife had a phone call with a friend who lived in the state, and she suggested we drink a lot of water.... (H20), which provided the extra oxygen we were missing... and it worked.
    No more breathing issues. Thanks and Great TED!

    we all know we have to eat less and move more to create a calorie deficit ....knowing where it goes is irrelevant ....it dosent help you to actually do it knowing what the chemical reactions are ,its something the dieter does not need to know ....however what they do need is a way to make it easier and keep satiateed whilst dropping calories and increasing exercise .....weight loss is and always will be simple but it aint easy

      I am just a pharmacy student, and this is very general information. I encourage you to seek out registered dietitians (nutritionists are not registered, so I recommend dietitians) and other health care professionals.

    • Daian Moi
      Daian Moi 26 days ago

      He talks about the carbs and sugar plants make. Try to start by limiting those.
      Rice, bread, starchy veggies like potatoes. Limit yourself for example to 1 cup of cooked rice each meal or maximum 2 pieces of bread or tortillas. Speak to a healthcare professional for more details.
      Practice checking the sugar content of everything. The American Heart Association (AHA) recommends for most American women, a maximum of 6 teaspoons or 30 grams of sugar. For men, about 9 teaspoons or 45 grams max. That means no more Starbucks frappuccinos!
      And don't forget the #1 best thing you can do for your health: exercise! Weight/muscle training will grow your muscles and increase your metabolism, so you will lose weight faster. Aerobic exercise (or exercise that raises your heart rate) is very good for your heart, so be sure to do some of this too.

    The masses on the periodic table are not the masses of 1 atom but of 1 mole of atoms (6.02 x 10^23 atoms) of that particular element. (Avogadro's number)

    • Saras Raman
      Saras Raman 29 days ago

      At time 13:35 it is stated that the weight of a single atom of Carbon = 12.01 grams. I cannot place 1 single atom of Carbon on a scale and measure 12.01 grams. You say it very well when you state: If you take 6,022*10^23 particles of Hydrogen particles you'll get 1 mol of it but also 1g of Hydrogen. So 4g of Helium = 1mol Helium = 6,022*10^23 Helium particles. Thanks for clarifying.

    • M'Baku & T'Challa
      M'Baku & T'Challa 29 days ago

      Ehmm... no? No they are not? The numbers stand for the atomic mass of the particular element, which defined as 1/12* the weight of an Carbon atom. Avogadro's constant was picked so, that if you take k amount of Carbon atoms you'll get 1g of it. They found out how much an Hydrogen atom weights and divided 1g/(1,66*10^(-27) kg/particle) = 6,022*10^23 particles. => If you take 6,022*10^23 particles of Hydrogen particles you'll get 1 mol of it but also 1g of Hydrogen. So 4g of Helium = 1mol Helium = 6,022*10^23 Helium particles. Then the Molar Mass was created, which describes how grams you get from 1 mol of a substance. So for example if you want 1g of water you need (2*1u + 1*16u) * 6,022*10^23 = 18u *6,022*10^23 = 18 mol. So the molar mass of water is 1g/18mol, which again is the amount of substance I have to take to get 1g of it. It just so happens that the molar mass is equivalent to the atomic mass, since we defined that 1 mol of Hydrogen weights exactly 1g.
