Metabolic Rates and Weight

As we all know, people with relatively fast metabolisms can eat just as much food as people with slower metabolisms, but manage to weigh less, even if they don't exercise. This implies that at rest, a person with a relatively fast metabolism burns energy at a faster rate than someone with a slower metabolism. Doesn't this mean that a person with a faster metabolism uses energy less efficiently? I mean, using more energy to do nothing is certainly less efficient. Perhaps in today's world in which there is an over abundance of food and Humans don't have to hunt, this trait is a good thing because it prevents obesity. However, in ancient times, when Humans had to hunt for food, which made it more scarce, it would have been a bad trait as fatal starvation would be more likely. Anyhow, what do you think of this phenomenon?

I think i'm superior to fat people

I hate when people can eat more than me and weigh 100+ lbs. less. It makes me so jealous.foxhound_fox

I have to eat untill I make myself sick to put on weight.

I have a fast motabolism.

The energy I gain is mosty used for my cells to regenerate and whatnot. I don't exercise like a normal human being should incase for a distaster, but I don't gain weight either.

If I continue this habit, by the time I am 30 when my cell growth rate slows down including everything inside body slows down, I will convert the sugar I eat and convert into fat cells and have a belly. My face would be disgusting and it would look obvious then that I had not lived a healthy life style.

What is interesting is that those who have such wonderful metabolism grow out of it as they age. No all of course, but many come to a point in their lives where their metabolism doesn't keep up and they gain weight. They suddenly don't have the personality to stop eating, so they lose control. Interesting pehnomenon.

I eat constantly and manage to stay underweight. I have no idea how I'll cope when my metabolism changes in later life...

I hate when people can eat only a regular portion of food and yet be able to put on twice as much muscle as me after a workout.sonofsmeagle

This is funny, I'd consider myself to have a high metabolism but one year in and I feel I've packed on a nice amount of muscle without eating to oblivion. I think you just need the right expectations and patience. I speak for myself only though I suppose.

My friend can eat tons and not gain a pound... We all have a friend like that.FlippyMittens

I'm like that. I'm 5'6" and weigh 135 pounds or 9.6 stone.

They work harder and smarter and eat and sleep right. It kills me when people call me gifted but are in the gym looking at women and talking. That said at least you know what the inside of the gym looks like unlike most of the unmotivated obese amphibious bipedal lumps of cow dung walking around.

I don't get the whole fast/slow metabolism thing. You need as many calories as you need for your body to perform its functions. I burn as many calories as the nest guy. I don't just randomly burn 100 extra cals because my body feels like it, to have the calorie used, it needs a reason. They don't just poof into thin air. Now the more muscle you have the more you burn to sustain it, so it makes sense bigger people would need more calories to live, but muscle doesn't just poof into thin air either, you need those amino acids to go help build/ repair broken muscles. People who say they have a slow metabolism just want an excuse in my eyes. Like i said, calories don't just poof, they need to be used, you can't just randomy have calories go away for nothing, it makes no sense. To lose weight you need to use more calories than you consume, easy as that, your metabolic rate is only as high as it needs to be, there is no way it will burn more calories than you need because it just can't, you can't expend energy without using it.
