For highly processed foods, I agree.
But for relatively unprocessed foods, seems completely reasonable to me at first glance. The relative sugar content of, say, an apple, is dependent on all sorts of parameters (sun, water, soil…). The gluten content of wheat, iron content of vegetables, all of these things are variable. The more “natural” a food is, the higher the variability (as opposed to, say, artificial candy — that should be pretty uniform).

We can’t even measure calories accurately, never mind predicting how much your specific body will actually absorb. Maybe we could be more accurate with vitamins and stuff, but I dunno.

The only way to get an accurate reading on calorie count is to burn it. 1 kilocalorie (nutritional calorie) can increase the temperature of 1kg of water by 1 C°

But burning isn’t how your body utilizes the calories. Some things burn just fine yet are entirely useless as a (human) food source, like wood. This complicates things.
For instance, we still don’t know if our bodies can actually use ethanol (drinking alcohol) as a fuel source. Is that vodka shot adding to your daily calorie intake?

Vodka’s back on the menu, boys!

Even more reason there is plenty of science to be discovered. Until then, the rough estimate we have is still proven to work (calories consumed minus calories burned).

Sure, but that is measuring calorie content, not what your body can absorb
eatCasserole@lemmy.world 6 months ago
Exactly, which makes the whole endeavour more of a guessing game than a science.

I mean there’s no way that they’re gonna be able to do metrics for every person since every person is built differently so there has to be a common standard. Or you you saying that certain types of calories are burned the same way for all people?

What? Calorie is a perfectly accurate method of measurement. Just because your body might absorb more or less than the next person doesn’t change the amount of calories in a food.

Measuring calories in food is not accurate. Measuring calories by burning fuel is, but that’s not how we use food.

Lmao so measuring calories in food isn’t accurate cause you don’t consider it food when measured?
That’s gotta be the funniest counter argument I’ve ever heard
