That shows a complete lack of understanding of how our energy systems function. When you lift you are using muscle glycogen. The type of lower rep, heavy lifting most of us do barely touches muscle glycogen reserves. After muscle and liver glycogen are topped off, any extra gets stored in fat cells, just like all extra calories we take in. It generally doesn't take more than 50g of carbs to replenish glycogen lost in a normal training session.

I've had some of my best lifting sessions while having not eaten carbs for 20+ hours.

Edit; even this is a vast oversimplification of how these things work. People just don't get that when you're talking about something this complicated, normal logic just doesn't apply.
