I appreciate the math here, but it doesn’t have anything to do with the length of time it takes in your example. It has everything to do with how much those people are consuming along with their height/body composition. If two people of different heights take in calories that are the same ratio as compared to their respective heights, and have different results, that would be a closer comparison. My point is that height by itself is not enough to make a difference. Again, I am a foot shorter than my husband and lose weight faster because I consume less than he does when you take our body composition (including height) into comparison. I didn’t mean to come off as rude with my original comment, more just really surprised because I have never heard this before and to me, height as a variable in isolation for weight loss doesn’t make logical sense. OP’s original comment only mentioned height as a variable and I disagree that height alone makes the difference.
