Our metabolism is like a campfire. When we eat food and drink, it’s sent to the liver to be metabolized and burned away like wood to produce heat (calories). If we hork down too much, like three out of every four people in America, we’re tossing a large amount of wood on a fire that will not get burned. This extra wood is then stacked up in our body as glycogen and fat, and saved for later.
Glycogen is extra carb storage in our liver and muscles. It’s readily accessible and our body’s first choice for fuel when food isn’t around. But glycogen storage is limited. When it runs out, we convert our extra calories into fat, which is stored virtually everywhere in the body–around our organs, in our bloodstream, or packed into our guts, asses, and hips.
When we have an abundant storage of “wood,” things can get out of control. Since our bloodstream is like an interstate system, when it gets too crowded, it doesn’t work efficiently. Too much fat on our freeway can cause traffic jams, car accidents, and jack-knifed 18-wheelers, inhibiting the performance of our daily physiological needs. Over a period of time, this leads to obesity and chronic diseases–like type 2 diabetes, fatty liver, heart disease, and cancer.
So what are the sources of calories?
Carbohydrates, protein, alcohol, and fat can be burned down to produce energy. Carbs and protein give off the least heat, at 4 calories per gram. Alcohol (my favorite) comes in second place at 7 calories per gram. And fat provides the most heat at 9 calories per gram.
Sticking with the campfire example (pun intended), carbs are like kindling. They burn quickly and are a necessity for getting things started when building a fire. They are great breakfast foods.
Protein is like a bundle of wood you buy at the grocery store that costs about $10. It’s good for building your fire and providing a framework. Protein takes longer to burn.
Fat is like that big fat tree stump you put on the fire. It takes forever to start burning, but when it does, it provides fuel for a long time.
Alcohol is like lighter fluid. You might use it if you suck at building a fire from scratch. At first it produces a bright, amazing flame and you think: This fire is awesome. Who needs wood when you got lighter fluid, brah? But the fire, and fun, doesn’t last. The flames usually die off in about 10 seconds and you’re back where you started from.
Drinking alcohol has the same effect. The moment you take a shot, pound a beer, or drink a fancy glass of rosé, the alcohol gets absorbed into your bloodstream and the flame ignites, releasing fun, drunken energy. But the flame burns away, and you soon feel like a burnt out stick.
How much fuel do you need?
Well, it depends. The size of your body, and how much you use it, determines how much wood to toss on your campfire. The smaller you are, or the more inactive you are, the less wood you need. If you’re tall and active, you’ll need more.
Most people follow the 2,000 calorie-a-day standard, but this is an average amount. A small, sedentary female will get fat eating 2,000 daily calories because her campfire is small. But a gigantic, active manbeast will lose weight because his bonfire is ginormous.
Your metabolism is like a campfire. Know how much wood you need to toss on it or you’ll get fat. To find out, google “calorie calculator,” choose one of the millions of calculators, and plug in your information. This knowledge will help ensure your campfire burns bright and incinerates anything you toss into it.
