How does the body know how many calories are in the food it just ate?
In: Biology
Well, it doesn’t keep track of the number. But it has a system that tries to extract as much energy from the food you ate, turning the excess energy into fat, and the food that doesn’t get converted into energy, instead gets converted into waste. There isn’t a counter that goes “YOU HAVE EATEN 2000 CALORIES”, but your body is built to take the food you eat and make into the energy you need to live.
