Muscle is very, very tough to build up, that is, to hypertrophy. Unless a person is on a very rigorously designed body building regimen, outside late adolescence for boys, weight gain is almost certainly fat.
That's particularly true for women and older men. It's extraordinarily difficult to gain muscle weight. I'm not talking about getting stronger--muscles normally get stronger without increasing size and weight.
Back in the day (early 80s) the top female bodybuilders--the women winning Miss Olympia--looked like "fitness models" today. In 1985, body builder Cory Everson won Miss Olympia with a body clearly built on steroids (as noted when comparing her 1984 body with her 1985 body--not even a an adolescent boy can build that much muscle that fast). But when she did it, the doors came off and female body builders either decided to use steroids or retired from competition.
Weight loss is primarily a matter of diet.
A 26-mile marathon burns about 2500 calories...that's a Big Mac with super-sized fries and a large Coke. The military prescribes 3,000 calories per day for soldiers who go on patrols every day carrying 90 pounds of gear in Afghanistan and Iraq.
I burn about 130 calories in 30 minutes on my elliptical--a single 12-ounce soda. It's a heck of a lot easier to skip the Coke rather than work out another half hour.
But you have to exercise while dieting to maintain muscle tone and mass.
