If Idina says she has a “good metabolism,” it most likely means her body efficiently burns the food she eats for energy, rather than easily storing it as fat.

What “good metabolism” usually implies

  • Her body converts calories from food into usable energy efficiently.
  • She may find it easier to maintain her weight because she burns energy at a relatively higher rate.
  • In everyday language, people often mean she can eat without gaining weight quickly, thanks to this efficient energy use.

In multiple homework-style explanations of this exact question, the correct interpretation given is: “Her body efficiently burns the food she eats.”

TL;DR: “Good metabolism” for Idina most likely means her body is good at turning food into energy and burning those calories efficiently, not that she just runs faster or is automatically healthier overall.
