Excercise results/calories burned are lower as you become fitter?

Hello,

This is a general question based on what I'm seeing. I seem to be burning less calories as I became more fit and lighter. It makes perfect sense, but I am working a lot harder than I used to. I am wondering if this is a result of the body adapting to a higher level of exercise. Any thoughts?

Roughly 3-4 years ago, I started my (very) long weight loss journey. I was a 5'10", 284 lbs male. I did basic cardio on the elliptical 3-4 times a week for about 30 minutes, and I kept at it for a long time. I am now 182 lbs and I am doing the Insanity programs. If you don't know what that is, it is basically a home workout program that lasts anywhere between 35 min to an hour, 6 times a week. It's pretty crazy (and I highly recommend it).

Early on, I used to be able to burn 500-600 calories in about 45 minutes on the elliptical. Even when I was about 200 lbs that seemed to be the case. I haven't done the elliptical in a while, but I seem to be burning a little less doing a typical 40-45 minutes Insanity workout. That seems a little strange to me considering that I'm too tired to move after Insanity, whereas a long elliptical workout doesn't really drain my energy as much.

I guess I'm just checking to see if this has happened to any of you. As I said, it makes a lot of sense to burn less if I worked out at the same rate, but I'm not, I'm pushing a lot harder than I ever have. Unfortunately I am a very analytical person so numbers matter to me (even though they probably shouldn't)...
 
The amount of calories that you burn is based not only on things like the speed that you move but also on your weight...

If you think about it - someone who is 182 pounds would have to work harder if he was to walk a mile at 3mph if he had to carry something weighing 100 pounds compared with the easy that he would walk the same mile at 3mph if he was not effectively doing some weight lifting as he went...

Now that you have lost weight - you need to work a lot harder to burn the same 500 calories than was the case when you were 102 pounds heavier.

So, wearing something heavy on your back may help burn more calories?
