It will - but sadly, not by all that much. If you were significantly overweight to begin with, even though you may add a few pounds of lean mass, you still weigh a lot less overall and your maintenance calories will be lower than they were when you were fat.
Are you judging maintenance calories just from weight alone?
Actually, I never do this. I track my intake on fitday and track my weight. If the trend of my weight doesn't fluctuate, I'm eating at maintenance.
Excess adipose just sits there as storage for the body to use if it's not getting enough energy from food. Sure you need to have more calories to maintain body heat through more mass, and there is more blood circulation required but it's not as much as you would think. Every lb of lean mass however requires a specific and significant amount of energy for expanding and contracting, feeding nutrients into, etc. One lb of muscle requires far more kcal support than a lb of fat.
I absolutely agree with you.
Honestly I think we're splitting hairs here.
No, we TOTALLY agree here.
MY point is that if you have someone who is obese, say a 5'7" woman who is 40 lbs overweight - well, let's suppose she starts lifting weights and fixes her diet. Loses the excess fat, packs on a little muscle. Let's say for argument's sake she goes from 105 lbs lean mass, 170 lbs to 115 lbs lean mass, 130 lbs. (Okay, this was me. FINE. Took me four years. )
Now she weighs 130 lbs, and has more muscle on her than she had before. Awesome.
But she only gained 10 lbs of lean mass. She's down 40 lbs net - lost 50 lbs of fat.
If she's lucky, her metabolism is the same at 130 as it was at 170 - but it might have dropped a bit. Mine did, a little. Not much. I'm SURE the lifting helped me NOT DROP it down to nothing, I'm not complaining, trust me!
Now, if we're talking a young man in the same situation, he may have managed to gain three times this much muscle over this time frame. HIS metabolism will be higher when he's leaner.
Make better sense now?
It stimulates your apetite because you are burning calories. When you aren't doing the cardio (like an off day for example) then the only reason you would have an appetite spike is because your body thinks it's going to do some cardio. I think I'm talking in circles.... what I mean is cardio spikes the appetite because it wants fuel for the calories you're burning, not because of a change in your metabolism. Yeah....
Actually,
the activity itself stimulates the appetite.
"The present data suggest that low rather than high-intensity exercise stimulates ghrelin levels independent of exercise duration. "
Translation: low intensity exercise increasing ghrelin is responsible for the increased hunger that ensues. IE jogging makes me freaking HUNGRY LOL!
Carbs do this to me too - but I need them for my lifting and sprinting so I target them around my workouts.
I lift and do HIIT three times a week. I eat about 2300 calories on these days - and about 1400 calories on my non-training days, where I do little or no cardio. I'm actually hungrier on the training days. I blame carbs. <shakes tiny fist in rage>
That plus I was fat for a long time. Fat cells shrink, but sadly they're forever. And they want to be FED. Grrr....
Try HIIT, sprinting, and running (not jogging) running for a straight hour. Did I mention I love you Built?
I'm so glad you love me!
I pretty much ONLY do interval work. Read
my article and you'll see why:
