Hey Thereupon, that's a really good calorie calculator site. Just for fun, I plugged in my stats and used the Katch-McCardle formula (since I have a pretty good idea of my body fat %). It came up with 2340 calories a day to maintain, which is pretty much what I eat. I've been maintaining, while losing some fat, for 3 months. I'm a big fan of Jillian, and I know everyone is different, but I think 1200 calories just isn't enough food to get an adult through the day. Certainly not if you're doing this program! Eat back enough to at least net your BMR calories.
I've tried four of the recipes from her Fat-Burning Meal Plan, and they are all delicious if time-consuming to prepare. Since I need to eat a lot, it usually takes 1.5 portions to feel like enough food, though.

I agree karint74 - I was baffled when I saw 1200 calories in the meal plan PLUS workouts...! I can't imagine myself being able to stay awake longer than a couple of hours on that! I guess it's difficult to set a target that suits absolutely everyone, but a few more guidelines or some kind of "calorie goal chart" might have helped.... A blanket recommendation of 1200 seems a little silly. It's one of my only gripes with the program so far, but fortunately it's something that can be easily adjusted!

Edit: @Hurley1203 - The "eating back calories" thing confused me, too. That's why I went with the calculator. Since I'm being consistent with the amount of time I exercise per day (which is pretty easy with JMBR - 30 minutes / day), I found it simpler to plug it into the calculator, set my new targets, and forget about measuring my exercise on MFP. Since the amount of calories burned for the exercises in the MFP database are estimates and vary hugely with each person (as do features on exercise equipment, HRMs etc), I decided it was a simpler route for me. (And it appears to be working!)

I saw that about the macros as well. I was a balanced oxidizer, so I adjusted my macros.

Yeah... Love her workouts, but the food plan.... meh. I looked at it once and never looked again.

I was following Jillian's recommendations but was so hungry at night it was starting to become almost counterproductive (like in I was going to binge if I didn't more food). I checked out the thread of MFP about TDEE and figured out everything. Now I am eating TDEE -15% and my macros are 20% carbs, 50% protein, 30% fat. I feel a lot more satisfied and usually keep under my calories when some of my workout calories are used. It's too early to know what the switch is doing but I feel really powerful and strong right now.

Interesting enough, another MFP user posted Jillian's quiz about oxidizer levels and it was right in line with my macros. I think that thread is either on JMBR board or the JM Challenge Board.

I am amazed, I just looked up the fast oxidizer macros and it all totally coincides with what macros I find work with me for weightloss. e.g. http://drlwilson.com/Articles/fast diet.htm maybe there is something to that.....

I love Jillian, but I don't agree with 1200 calories as a blanket caloric intake for everyone, either. I think this program is designed for maximum weight loss and in that case, 1200 may be appropriate, but it isn't for everyone. I am trying to maintain muscle while losing body fat, so I'm eating way above 1200. I suggest everyone look into the "Eat more 2 weigh less" group as they discuss why eating at a deficit doesn't always give you the change on the scale you desire. I was eating 2200 calories during a muscle building program, then dropped to 1700 and lost 2 lbs in 3 weeks.
