Your body doesn’t prefer to store energy as fat, it prefers to store it as glycogen in the muscle and the liver. Glycogen is like the chequing account and fat is the savings account, you’re body spends from the glycogen fund and if that fund is full it stores the rest for a rainy day.
The money metaphor breaks down because you can’t empty your savings account all at once when you’ve saved up a ton and do a marathon or something. Anywho your body prefers to use glycogen which comes from glucose which is sugar which comes from carbs.
Neat fact; your body likes sugar so much if you don’t have any it will make some. If you exercise hard in the gym or in life and deplete your glycogen your liver will convert protein in a process called glycogenesis. But it won’t do it super well so you won’t really refill your stores and you’ll use up protein that could have gone to building and maintaining muscle fiber. So carbs post-work out is a good thing, in fact the quicker the carb the better, you can have candy and junk food after a work out because the body will grab it and store it as glycogen and doesn’t want to have to work too hard to get it. All those sports drinks and bars and crap? They’re just candy. Candy with extra salt and lightning bolts.
The notion is that one has to fuel up for the day and you don’t. You’re fueled. We all have enough carbs and fat at any given time to do anything that comes up; from an energy stand point we all have enough in the accounts to do about a half marathon right now. And one cookie has enough energy to get you the rest of the way.
Your body send out the alert signal of hunger (well, sugar cravings that we call hunger) all the time because money is being withdrawn from the chequing account in nickels and dimes and your body is one of those freakish cheap skates like oh no if we keep spending like this and we lost our income right now we’d be broke in three and half years! but your fat cells are like chill dude, we’ll pick up the tab if your card gets declined.
More like we’re always chipping in a percent based on VO2 max and ketosis is a thing where fat will pay the whole tab but I want to keep this metaphor accessible.
Anyway this is where we need to goal-split: If your goal is to lose fat you need to deplete your glycogen by working hard, resting long, and not having any carbs. Leave the chequing account empty so it’s filled by the savings account. But by god get your protein otherwise your body will break down your muscles. If you’re an athlete and you got lots of athlete shit to do get carbs immediately after your work out so you’re replenished for your next work out – or your job or parenting or whatever. But mostly working out.
