Well, sort of. A lb of protein has about 1400 calories and that is dry weight.
Since muscle is about 66% water, a lb of muscle is about 500 calories. A lb
of fat is 3500 calories and fat tissue is virtually 100% fat. But you are
right, the metobolic requirements for maintaining a lb of fat tissue is
virtually 0 and just having a lb of muscle requires a certain expenditure of
calories per day. So if you do a little weight work to build muscle mass, even
though the weight lifting does not burn many calories, maintaining the muscle
will.

Well, it depends on how hard you push. Have you looked at the legs on some
cyclists?

That depends on what you mean by "as people think".

In a practical sense cycling burns far more calories the almost any other form
of exercise. Running, in a practical sense, does not burn much because most
runners can not run that long per day without either hurting themselves or
pooping out. Cyclists can cycle for hours per day easy.

The only two exercises that I know of that burn more calories per hour then
cycling are cross country skiing and rowing (where you use your legs, arms and
back muscles). But both of those exercises are sort of less accessible then
cycling.

A Big Mac, Fries and Big Soft Drink has enough calories in it for most people's
entire daily energy budget. That is an extremely high energy mean and as such
it is a terrible example.

I think you are overestimating the benefits of anaerobic exercise but debating
it endlessly would be pointless.

In a functional sense, you are better off doing all three. I can not think of
any form of exercise regime that can not be sabotoged by a poor diet. So diet
is obviously the most important one.

A trained cyclist easily can burn as many calories per hour as a
cross country skier, runner, swimmer, or rower. The VO2max of all
elite aerobic athletes, when adjusted for body size, are identical.

This was covered in a thread several weeks ago.

How do they manage that when they don't recruit as many muscles?

There's no 'sort of' about it. Fat contributes to calorific burn at about
4.5kcal per kg per day. Muscle is about three times as metabolically
expensive as fat. Therefore, if person A is 75kg @10% body fat and person B
is 75kg @20% body fat person A's maintenance calorific expenditure will be
higher than person B's.

Diet is absolutely the most important factor. And most people are lousy at
keeping track of what they actually eat.

Neat. You are sort of like a warm fuzzy version of Lyle!

Er...minus the lesbian contingent and stuff. And I'm not implying you'd do
anything gay, like roller blade. <g>

Oh, it's not that stuff which bothers me. It's the warm and fuzzy bit. I'd
better started dusting off the "********"s.

The short answer: once trained, they all have enough muscle to max
out their aerobic system.

This was covered at length several weeks ago. Maybe google can bring
it up.
