Kcals & Mass

Hey, Tom, I figure you've got a good answer for this one.

Kcals is strictly a measurement of heat capacity (raising the temp of 1 gram of water 1 degree celsius--I think). So how then, is this equated with the measurement of weight, vis a vis: losing weight? This would seem to imply that all adipose tissue is the same. Or--is it not the same and then this causes the fluctuations we see in weight loss from individual to individual and even within the same person?

On a side note, but possibly related, why do we get plateaus? For the last 2 weeks, I've been stuck at ~272 lbs. Finally broke through 2-days ago and am now at 267. Could this be related to the above issue?

First, the plateau issue:

We plateau when our body hits a point in weight it was at for a while and it reactivates an older paradigm, or set point where our bodies feel comfortable at. Basically, it's saying "Hey, I've been here before and it feels pretty good!", and it hangs there for a bit til you more or less convince it to budge......sounds strange but it's true, you hit homeostasis at the plateaus.

kcals/pound of fat: 3500 kcals burned= 1 Pound of fat

Yeah...I knew this. The problem I'm having is this:
If I'm doing the same activities, I'm burning the same calories. I should continue losing the same weight. It should be like clockwork if a calorie is a calorie is a calorie. Right? But it doesn't happen this way. We occasionally plateau. So, perhaps a calorie isn't always a calorie? Since a calorie is a measurement of energy and not mass, perhaps fat-cells are slightly different from person to person. If they're different person to person, perhaps they're different within the same person and a calorie is sort of just an averaged out value, like the various caolric measures for activities.

What happens is as you lose weight, your body also becomes more efficient in burning those calories as well, so you need to change the equation a bit as far as diet goes.....

Substitute a bit more protein and reduce the fatty intake a bit to restart the ketosis cycle involved in burning fat. Increase the activity a notch as well. The ironic thing is that as you get in better shape, it gets harder to raise the HR high enough to stay in the sustained burn zone of 65-70% Max HR, because you are in better shape!:D The other factor, you hit right on the head, we're all one offs (Custom DNA code), and the tables are truly based off of a statistical average with a fairly high level of correlation (approaching .82), but individuals do respond differently.:)
