wondering if a person who is 260 pounds "5'11.. vs a person who is 170 "5'8in weight loss.. is it easier for the 260 person to lose more weight in the same amount of time? or do they both have the same chance?

we someone who its 260 pounds should take longer beacse its no healthy to lose to much weight to quick. it you loss it more slowly you have a better chance of keeping it off.
