They used to say that you shouldn't carry a pack that was any more than 20% of your body weight for comfort. I don't think they were talking about base weight, but even at total pack weight I'm sure today's standards are much less. My base weight in summer for a multi day trip is 10% because I weigh 180 and my base weight is 18 pounds. (does not include what I am wearing, consumables or poles). What is your pack/body weight ratio?

180 lbs = 82 kilo
18 lbs = 8.2 kilo

PS. some items weigh the same no matter your body weigh, like a stove and generally speaking a one person tent weighs the same no matter your body wt. so lighter wt. people have a disadvantage. They probably do eat and drink less of course.
