It's weird how every time one of these studies comes out, there's always a couple idiots screaming:
Not only doe they always remind me of the Horton Hears a Who, they never fucking learn anything.
They were told something in 6th grade science class and latched on.
Completely ignorant that there'd be a reason that children don't get taught everything and usually only get broad specifics.
I think people who obsess over calorie in calorie out reasoning drastically underestimate how variable the calorie out side can be with factors that aren't exercise. Digestion isn't 100% efficient, some calories are excreted. Small changes in body temperature have large changes in total energy consumption. Sleep quality, time awake, base heart rate and respiration rate, etc. all vary and have impacts on energy usage.
Parroting CICO sounds scientific because it borrows credibility from thermodynamics, but people aren't closed systems and applying laws of thermodynamics takes a lot of nuance in complex systems with a variety of inputs and outputs.
What you are saying is equivalent to saying one kilometre is longer or shorter, depending on what time of day you walk it .
Or maybe they’re saying that walking that kilometer can be easier or harder, depending on whether you’re going uphill or down, and whether there is snow upon the ground
The kilometre doesn’t give a fuck.
No, it doesnt, but walking to school is more than just distance. The effort and time required, the likelihood of success, are affected by other things as well.
Are they wrong? I don't understand. A calorie is a calorie; it doesn't change energy composition. The calorie is just a measurement of energy content in a given product. If it's 15, it's 15. The energy content doesn't change just because you eat it at 2 am. Your body processes the calories differently, not the calorie itself is diffrent. Am I misunderstanding the study?
You're misunderstanding is you think the basal metobalism while asleep is the same as awake...
I'm sure there's lots of other things, but that's what really giving you trouble right now.
It's an incredibly basic part of biology
Why does that matter? If I burn 2000 calories a day, why does it matter if I burn them at a lower rate while asleep? I’m still going to burn more later, no?
Because you use less calories while you sleep, so excess calories are converted to fat...
And it's harder to burn calories of fat than use calories directly.
So eating late in the day leads to new fat forming. If you ate the same earlier, it would be used immediately for fuel
This is all incredibly basic stuff...
This article mentions that one of the factors is that late at night you have fewer hormones suppressing appetite so you would potentially eat more. That makes sense as a reason you would gain weight. It does say that you burn fewer calories at that time too (which might mean you convert more of it to fat at that time, and if you don’t burn those excess calories later you’re going to be stuck with it…)
But I don’t understand what you’re saying. It almost certainly takes more energy to convert calories to fat and then back to usable energy for your body to use… So what? If you eat 2000 calories, turn some of it into fat, and then burn 2000 additional calories later (in addition to the energy spent converting it to fat) you’re technically going to be burning more calories than you’re eating and you will lose weight.
I’m sure there is an effect of when you eat and how that makes you store fat and how that can unintentionally cause you to consume more calories than you think… but what you’re saying doesn’t make sense to me thermodynamically.
Because you think a human body wants to be "healthy" ...
It doesn't, it wants to pack on all the fat it can to survive periods where food isn't plentiful.
We didn't evolve for unlimited cheap calories, our bodies still act like we're living in caves.
Seriously, this is all very very basic stuff, you'll learn a lot more reading about this then asking questions on social media and hoping you not only get the right answer, but explained in a way that makes sense.
BECAUSE THIS IS A HELL OF A LOT MORE COMPLICATED THAN CICO
Something I've been unable to explain in a way you can understand.
I doubt bolded all caps will help, but that's literally my last hailmary.
Go read some actual scientific texts if you want to learn more.
What's that supposed to mean exactly?
Your body loves fat.
It wants as much as possible.
To burn fat, you have to first use everything in your stomach, and then push through "the wall" where you keep exercising after your body says you need to quit.
Then your body will start the process to burn and use fat for energy.
So if you eat a lot at night and convert it to fat as you sleep. It's going to be harder to work off that fat than if you had ate earlier in the day.
