Facilitated diffusion does not use cellular energy.
Since the transportation of molecules occurs through the concentration gradient, it doesn’t use cellular energy for transportation of molecules.
The burn of calories is connected to gender, mass and the age. These characteristics are the similar for both individuals, so you have to look for the outcome of the body fat percentage.
Muscles are an active tissue which suggests that at rest they burn calories in a bigger proportion than fat. So, the male with more muscles will likely burn more calories at rest.
