    But would you rather have 2KG of lead dropped on your head or 2KG of feathers?

    Just like weight calories are calories, but eating 1000 calories of lettuce vs 1000 calories of peanut butter is a big difference. Lettuce has fibre, is filling and the volume of lettuce you have to eat for that many calories is insane.... In comparison it is less than 200mg of peanut butter.

    If I only ate 1000 calories of lettuce I would be extremely malnourished...

    You would be better off with 1000 calories of apple pie or Bacon cheeseburgers.

    Indeed...

    Not much of this makes sense but the one that I have to challenge is the notion that lettuce is filling?

    These extreme comparisons are so unhelpful. No one eats only one kind of food - and has to choose between lettuce and peanut butter, why can't a person eat both? Why always a false dilemma?

    How dare you introduce common sense to this line of thinking...

    I logged 5900 g of romaine lettuce, and it was actually surprisingly well rounded. Lower on fat than I would want (although 1000 cal will do that), but not bad for protein on that low a cal diet, and with that much, all 9 amino acids were covered.

    But who can eat 13 lbs of romaine lettuce? It's absurd, and not healthy for the reasons monodiets are generally not a good idea. And possibly that that insane amount would have other bad effects, of course.

    (Only spinach is better, nutritionally and in terms of amount, but again over 9 and a half lbs would be a struggle, and a completely insane and stupid diet that would no doubt leave you feeling poorly.)

    I really am curious why people think the lettuce vs. peanut butter comparison is meaningful. Yeah, they are different, but not because one is clearly better on its own (different diets may be better with the addition of one or the other or both, depending), and -- back to the topic -- not because their calories are different or distinct or have special properties depending on where they come from.

    The quantity of vitamin K would also be a concern even for someone with otherwise normal coagulation factors and a relatively sedentary lifestyle.

    The iron, I think, in spinach makes my teeth feel funny if cooked. So no to eating mountains of it.

    What if you got hit on the head with 2KG of spinach? Think of how badly that would hurt because of the iron!

    Would it hurt as much as 2kg of feathers tho'?

    TBH though Id rather get hit by 10 pounds of feathers in a pillowcase than 10 pounds of bowling balls...

    Yes, a calorie is a calorie however I find it far easier to stick to my calorie goal and less likely to crave sugar if I skip the refined carbs and get plenty of my calories from protein and fats. I’m big believer that nutrient rich foods have a satiating effect.

    I guess, for those who are struggling with that one:

    1lb of muscle occupies less volume/space than fat. So it's accurate to state that one cubic meter of muscle is heavier than one cubic meter of fat. But a pound is a pound; a kilogram is a kilogram. If you put a pound of muscle in one pan of a balance scale and a pound of fat in the other, the pans will be even, but the pan with the muscle will hold a smaller amount.

    why?

    it's still 10 pounds. It's just going to be a lot more actual surface area hitting you.
    A sake of 10 pounds of feathers is going to be like pillowcase or larger- vs a bowling ball- that's just you know- 10 pounds.


    it's still going to suck. I'm so confused about why you said this.

    You can have them WEIGH the same- but because one is more DENSE than the other the AMOUNT OF PHYSICAL SPACE they take up will be different in order to get them to balance the scale.

    Although IIRC the difference isn't as dramatic as that image portrays. Don't ask me for sources though because lazy AF.

    Why?

    Because of a lack of understanding of physics.

    The reason a 10 lb pillow seems less threatening than a 10 lb bowling ball is because not all ten pounds of feathers will make simultaneous impact like the bowling ball will.
    Replace the pillowcase with something that will compact the feathers into a tight ball so that the sponginess is lost (meaning that the entire 10 lbs of feathers will make simultaneous impact) and it isn’t fun anymore.

    When you compare getting hit with a ten pound bowling ball to a ten pound pillow, you’re really comparing ten pounds of bowling ball to a couple ounces (if that) of feathers, because that’s all that’s going to make impact at once. The rest of the feathers hit you later.

    It’s like saying I’d rather take ten bites out of a ten pound bowl of lettuce rather than eat an entire jar of peanut butter.
    No duh, it’s because you don’t have to eat it all.

    That actually may shed some light on why people try to compare 1,000 calories of lettuce to 1,000 calories of [insert favorite junk food].
    It’s because they know they ain’t gonna eat no 1,000 calories of lettuce. That, to me, further proves the point that it’s all about how many calories you eat.
    If eating lettuce means you eat fewer calories, that’s why eating lettuce works for you.
    It has nothing to do with the calories in lettuce being better than the calories in Oreos.

    I think in the "getting hit by" scenario- my assumption is the material is compacted into the smallest space possible- so not just ten pounds of feathers in a big garbage bag and good luck letting it waft down and strike you- like putting them in a pillow case- or a grocery bag- smallest container possible. It would super suck.

    I feel like we *may* have jumped the shark a wee bit on the calorie conversation also. LMAO

    Just not 2 kg of peanut butter. Pretty sure that stuff is a nightmare to get out of one's hair.

    But if you used the crunchy PB it would probably be a good exfoliate (and moisturizer) for the face.

    Isn't there an urban legend that peanut butter gets chewing gum out of hair? I think someone made it up to get people to add to the icky hair...
