Why am I not losing weight???

By the way doing doubles of high intensity stuff probably isn't the best plan. At a certain point fatigued muscles don't perform as they should, and even though your HRM may say you're burning X calories, you no longer are, it takes a while, but I could see doubles of P90X reaching that phase.

I did P90X for a round, it was ok, I prefer my own routines, shorter, but harder (similar to insanity, but I do more resistance and less cardio) so I have an understanding of what's involved. I have respect for Tony Horton, for a mass produced DVD he does ok, hate his food plan though. It's not really based on actual science, more on popular quasi-science.

"are you saying you're burning 1800 calories a day with exercise? I find that hard to believe. but then again... "


I could be calculating wrong... but I go to the gym and lift heavy weights for half and hour, no breaks talking to people. Then I walk with incline for half an hour. Go home do 2 p90x, then walk the dogs for an hour. Everyday.

But I have seen the error of my ways. I read the links offered, which all make sense. I need to find the happy medium...

maybe you do, I didn't realize you were doing doubles of P90. But that sounds like overkill. I'm not a big fan of walking by the way. At least not walking for someone who is fit enough for P90X. that's just a personal thing. It's not an indictment on walking. Walking is the thing our bodies do most, thus lots of muscle efficiency, any time your muscles become efficient, they burn less calories doing the same amount of work. It's why people(trainers) recommend changing your exercise routine every 6 to 8 weeks, some call it "muscle confusion" but it's basically just making sure your muscles don't become to efficient at a specific exercise. For instance, instead of walking, try the rowing machine for 15 minutes, I'll bet it'll be a killer workout for you. Do that a couple times a week for 3 or 4 weeks then switch to the stepper, then try a moderate Tabata protocol program on a spin bike for a month (always do tabata on a spin bike, these bastardized programs aren't nearly as good)...etc. (FYI if you like the endorphin rush from P90, you'll LOVE what you get from Tabata, it's a million times harder, and only takes about 15 minutes).

Oh by the way, if you are burning 1800 calories with exercise a day (or even close) then I can say with a high degree of certainty that you're in starvation mode to some degree. You're creating a deficit over 2000 calories a day. I'm still surprised that you aren't losing weight though, that's a little odd to me. I wonder, have you had a lot of colds this year, or viruses (or just felt run down)? One of the first things affected by starvation mode is a compromised immune system.

This entire thread is a perfect example of why I LOVE this site so much!

SHBOss is absolutely correct. You are over doing it and that is not sustainable. Our bodies are amazing biological machines that are very smart. Your body knows it cannot allow the calorie deficit to continue. You have crossed over into starvation mode and your body will continue to conserve until you convince it that you are not really starving. Ease back into it. Like SHBoss said, if you immediately start eating more you will gain a bit back.
