Agreed. The proof of the claim in the article is effectively that people are different. John and Sarah burn calories differently, which means that calorie-in/calorie-out is wrong! You heard it here here first - soon Harvard will decry calorie counting as a form of white supremacy. Joking aside, the Harvard article is hardly more than clickbait. It appeals to people who refuse to put in the work to maintain an effective diet. They merely need to label what they eat as "whole" and can then eat as much of it as they want.
