"Shape" has really gotten in some good stuff in the past few months. They've added a column called "Weight Loss Q & A" that is terrific. June has a blonde in a pink bikini on the cover - yeah, I know, too-skinny sterotypes, etc. but what's inside is good stuff.
A key item & one we discuss here over & over again (on pg. 102): "it's impossible to fuel an exercise program and meet all your nutritional needs on just 1200-1500 calories a day. 'You can't build muscle if your body is in a state of starvation,' says Miami nutritionist Sheah Rarback, R.D., a spokesperson for the American Dietetic Association."
Also (same page, previous question): "In order to build enough muscle to impact your metabolic rate, you need to lift heavy enough weights that your muscles fatigue after 8-12 repetitions"
So the lighter weights, Tae Bo, etc. WILL tighten things up, which is not the same as stressing the muscle enough for it to grow, OK? Either is good; both are better. But you gotta eat enough! I worked with a trainer once who taught me that I was likeliest to add lean mass when my intake was high enough that I wasn't losing weight; I had to have extra calories around to build new muscle tissue; he told me the goal while losing weight was just to keep the lean mass I had to begin with, then change focus to adding lean mass after I had gotten to goal.
My nasty wake up call recently was finding out that in May i've lost three pounds - but all from lean mass. NOT what I wanted!
Hope this info is helpful!
