Help me out with TDEE?

sm0113

I am in the process of re evaluating my calorie/nutrient goals because I'm not losing and haven't been for a while... My goal has been to eat 1200 calories + some (if not all) of my exercise calories.
I'm about to start week 3 of jillian michael's body revolution, so on a good day I burn 350+ 6 days a week.
I really need to stay in control of my eating, and I need some help. I found this post about TDEE and I think i'm going to try increasing my calories, even though it makes me nervous...
http://www.myfitnesspal.com/topics/show/512956-tdee-what-is-it-and-why-you-should-not-eat-below-your-bmr?hl=tdee

With the tool that it gave, I got these results:

BMR:1621
TDEE: 2513
TDEE - 20%: 2010

So if I understand this right, it means that I need to eat at least 1621 on days that I don't workout and I eat 2010 on days that I do work out, and I don't eat my exercise calories unless my net is under 1621? So I always want my net to be around 1621?
I don't want to change my goals on my diary until I know that I have my head screwed on straight... Also, any success stories about people who have lost by eating this way and following the TDEE calculator will be much appreciated

Clearly, I'm stepping into muddy water and i'm nervous! But at this point, I'm lacking success and I'm desperate to try something that works!

Thanks

A simple approach would be to eat the 2010 daily. If you were sedentary for a day your TDEE for that day would be about that and on the exercise days you would have a deficit of 500 calories ( ~ 1 lb/week )

Or you could eat a bit less, say 1800, and have a deficit every day but a smaller one one sedentary days.

Depends how you can best control your eating - same every day, or feasting after exercise ?
