As I understand it, assuming we are talking about carbs, fats and proteins, as in their whole-food forms, not as in say a cookie, no, it's easier/quicker for your body to store say fat as fat than carbs as fat, which it will have to transform into fat first. Carbs are also loaded with water and fibers which makes digestion even slower to make this effect even better.

> Carbs and sugar are the culprit behind the obesity epidemic, not meat

Processed food as well as particularly overeating of delicacies like meat, cheese, eggs, fish, and oil and sugar prepared plant-foods, is the mayor culprit, I believe.

Nobody got fat from eating plain potatoes, beans and apples. It's also very hard to overeat on those kinds of foods because of the high water and fiber content. People get fat by eating too much dairy, meat, eggs, and plants prepared in oils, or other highly processed plant-foods, which are easy to overeat on.
