I weighed 200 pounds once. Now I don’t. I weigh around 150. But I have to eat around 1,200-1,400 calories on an average day to maintain this weight. That is not much.
My partner – who is two inches shorter than me and weighs thirty pounds less – eats more food than I do.
For her to reach and then sustain my former 200 pounds, I calculated that she’d have to eat roughly four times as much food as I do now.
For her to reach and sustain my current weight of 150 pounds, she’d have to eat 1.8x as much food as I do. That’s just how much faster her metabolism is.
Life isn’t fair at all, but I am still very glad I lost all that weight.
At a rough guess, she eats 1.2x – 1.4x as much as I do now, and still weighs less without effort. Metabolism bites. Or doesn’t let you bite, as the case may be.
