    I stand corrected. But there is some correlation between oxidizing and heat, right? Do it in baby steps, I'm really not getting it. I thought oils with low smoke points also broke down/oxidized at lower temps. Thanks in advance for any additional info.

    Smoke points follow the impurities in the oil. A virgin oil will have a much lower smoke point than a refined oil. Example: expeller-pressed coconut oil has a very high smoke point, but virgin coconut oil has a very low smoke point. Same thing goes with olive oil. From the list you posted:

    Olive oil Extra virgin 375F
    Olive oil Virgin 391F
    Olive oil Pomace 460F
    Olive oil Extra light 468F


    The more purified the oil, the more resistant it is to smoking. However, in terms of oxidation, the polyphenols in the virgin oils are antioxidants. The more you refine it down, the more antioxidants you lose and the more damaged the oil becomes with heat. Extra virgin olive oil will smoke almost 100 degrees before extra light, but it is far more oxidation resistant.

    Consider this: distilled water DOES NOT BOIL. You can heat it up to 300 degrees and it'll just sit there. Then, throw one drop of tap water in it AND IT WILL EXPLODE. That is because you are introducing impurities into the mix, which allows the boiling. FYI - never do this, you will potentially create severe burns from a massive explosion.

    I don't really think it has much to do with the fat itself. The polyunsaturated oils tend to have higher smoke points because they tend to be more refined. When do you see virgin, cold-pressed soybean oil? I've never seen it, but good quality olive oil and coconut oil are everywhere. Refined olive oil is just a smoke-resistant as refined soybean oil, but it'll be more oxidation-resistant thanks to the much lower PUFA content. Out of the two, which would I buy? Neither.

    Don't put your trust in anyone on this forum, including me. You are the key to your own success.

    Got it. Thank you. That clears stuff up.

    And not to worry - I won't do the distilled water experiment. I'll take your word on it.

    Distilled water boils. So does double-distilled & deionized "laboratory" water in sterile, dust-free, impurity-free containers. I do it every day. It boils like crazy.

Overconsuming fat doesn't speed your metabolism up any faster.

    If you sit on your ass and pound soda all day, as long as you're not consuming it alongside a fat source, it isn't going to be efficiently fattening. When you consume it alongside a greasy cheeseburger and fries, NOW you have a recipe for massive fat gain because your adipose tissue will suck up all that dietary fat and you won't burn any because you'll be burning the sugars from the soda preferrentially.

    Eating a diet high in protein and carbohydrate but with no fat isn't an efficiently fattening diet until you throw dietary fat in the mix. It happens to be that fattening foods are high in fat AND carbs - french fries, brownies, cake, cookies, doughnuts and chicken alfredo pasta all contain as much fat as they do carbs, so you burn the carbs and store the fat. It would be very difficult to get fat eating a diet of soda and pixie stix in the absence of all dietary fat. The average male has to consume something like 700g of carbohydrate a day before de novo lipogenesis (conversion of carbs to fat) is significant in the absence of dietary fat.

    But how likely is it you'll consume 20 cans of Coke a day and zero fat?
    Ok--- LOVE all your knowledge Choco... so so interesting. I'm still trying to take this post in. Since I was VLCing for so long and had a bad experience I am trying to figure out how to eat now. I want to be healthy, no doubt, but I also don't want to gain any weight now that I am adding carbs back in. I love routine and structure even down to what I eat so I need to figure out my new eating plan.

    After reading this post above - I'm figuring it out a little easier. Would you critique my idea of a healthy eating plan that will keep my weight in check?


    BREAKFAST: eggs and meat (bacon, sausage or my favorite-- chorizo sausage)

    DURING DAY: fruit and/or sweet potato

    DINNER: salad with tons of veggies and cheese


    This would be my eating plan except for Friday nights and Sundays. Please let me know how it looks to you.

    Thanks a million!!!

    That's it! I'm never believing anything I read on this board again!

    The water becomes super-heated because there are no particulates on which the gas bubbles can percolate. Once you introduce particulates from impure tap water, yeah, it explodes. So does throwing a fork or spoon into it. Or moving the container violently. There are youtube videos you can watch. Don't try this at home.

    Always use a boiling stick or chips when boiling water in the lab.

    I'm not sure if an oil smoking is the same process though. Water boiling is just a phase transition, but I think when an oil smokes, it's actually burning? I mean, it's not like the oil is vaporizing.

    Me? Carbs and no fat? Not likely. I've got half a beef tongue in the fridge with my name on it.

    And really I'm never going to do an experiment where explosion is the punchline. I've googled, and it looks like distilled water boils at about the same temp as tap water. Is that correct?

    The boiling point for water is 100 degrees Celcius. This is true for all kinds of H2O. However, distilled water can become superheated, as I explained above. Superheating - Wikipedia, the free encyclopedia

    There are also Youtube videos you can watch of people heating up water in the microwave. The water would not be boiling, but once they throw a fork into it, it will explode (not a literal explosion with fire, but the water will fly out of the container). For a while, you'd hear things in the news about people who were heating up water in the microwave, then they take it out, and either because they shook the container while removing it or because they subsequently placed a tea bag in it, the water flies into their face and they get burned.
