So, I look at this bottle of lemonaid. 130 calories per 8fl oz.
That seems simple enough. But it's liquid. Why do the calories even metabolize at all? Why do they not simply get pee'd out? I understand with solid food, it's because your body takes the chewed up food, and puts it into your stomach, where it then decomposes.
But the liquid shouldn't even have time to decompose. It's liquid.
Also, I don't understand when you gain the calories. If I eat 3 of these snacks that say 100 calories, which is now 300 calories, do I gain the calories over the next few hours? Or is it delayed a day or two?
Because there will be days when I eat almost NOTHING, and then my scale says I gained 3 lbs. But then there's other days where I feel I ate like a slob, and somehow lost 2 lbs.
So I'm wondering if it's delayed as it decomposes.
Losing weight is hard, but it might be easier if I understood the rules of how this all works.
Also, do farts have weight? Like if I weigh myself, and then after that let out a massive fart, and weigh myself again, would there be any weight difference? Or is it just weightless air that FEELS like you're lighter afterwards?
You broke the code. The calories your body takes in on any given day are by definition like 99% balanced with the calories that go out, no matter what happens. Almost all of what happens to gain or lose weight comes down to what your body decides to do with it, whether to spend it right away and how much to spend at any given time and how much to save. Personally I think this is why intermittent fasting works well: It demonstrates to your body that the food source is 100% predictable on a very set schedule, which means it's probably organized and reliable, which means we don't need to hoard a bunch of extra energy in case one day there is no food.
If the amount going in swings up and down and strong hunger signals get ignored some of the time no matter what, then it's going to decide we're in crisis mode, and ramp way way down on how much energy goes to the organs, general maintenance, building stuff we need, running the brain so you can think and have energy, and instead it's going to just store it all so we can survive. And that's what most people who are trying to lose weight with a specific diet do, and that's why it doesn't work unless you push it all the way to the starvation barrier where your body physically can't expend any less calories, and starts burning the reserves and crossing its fingers. And then, of course, once you start eating again, you gain all the weight back because oh fuck what's going to happen next.
That's not to say you can eat a ton of ice cream every day and just have it be fine. Eating a normal amount of healthy food and exercising will do good for you. But in my opinion if you're trying to lose weight, strictly counting calories doesn't really work because your body can ramp down expenditure of calories way more easily than you can ramp down the intake.
Edit: Oh, also to answer the question: You're suspended in a roughly fart-density atmosphere all the time, so my guess is the weight you lose by farting will be cancelled out by the lower displacement of your new volume without the fart inside you. Basically it's like weighing a balloon: You only get the weight of the plastic, not the air, because the buoyancy of the whole thing cancels out all the weight of the air.
If you were standing on the moon, and farted and then vented the fart out of your space suit, you would lose the weight of the fart, same as weighing a balloon on the moon and getting the weight of the air too because there's no buoyancy to cancel it out.
Edit 2: I guess a balloon is heavier than air, because the air inside it is pressurized and so denser than the air outside, but you get my point I hope.
