Fitbit and MFP

So I was feeling really good about myself Nov 6 (yes I have an exact day).

I have been taking progress pictures since starting mfp in august. I also upgraded my garmin and got a fitbit HR around that time. And I sync all my workouts to mfp with it. Now fitbit will say that I burned EX: 300c during my workout and sometimes mfp takes all those calories, none, or some of them. And adjusts my calories accordingly. My daily intake is set at 1500 plus whatever I have earned back from exercise. Sometimes I eat 1500, sometimes more sometimes less. It all varies. And I think (keyword) at the end of the week, it all balances out. I do eat pretty well and then during the weekend, I will go out to eat.

Since I got my fitbit, I started focusing more on weight training (p90x and weight focused Jillian Michaels videos). And more or less cut out cardio altogether. I started taking measurments too. The scale hasn't really changed but by a few pounds, small increases and decreases in measurements, older clothes fitting- I cant explain it. My body just doesn't feel as lean and cut as it did Nov 6. I feel more bloated now and I'm wondering if maybe I should start listening to mfp calories a little better. My workouts are roughly 3 days a week for 45m to an hour. And I am usually burning a lot according to my fitbit-300-500c a workout. And I'm reaching all heartrate zones for approximately the same amount of time. But my body just doesn't feel the same. This isn't some woman thing, I'm not pregnant or pmsing. I've been noticing for a little over a month that I just don't feel or look the same. It's almost like I'm losing the definition I had in that progress picture awhile ago. I've tried process of elimination and I'm going to try to be as detailed and honest with you guys as I can: My diet is a lot of protein bars and shakes. My work schedule is very weird and I need to adjust my eating schedule for my clients (I'm a caretaker). I try to eat a lot of protein. But sometimes I really just need to heat up that frozen meal which always has a lot of carbs. It seems I have been going over my carb limit a few days a week now...which didn't really happen before. Now frozen meals don't happen often, maybe 2 or 3 days a week and I do try to get the low calorie ones. But even those have a crap ton of carbs. I know frozen meals for me was an issue a few months ago and I thought I had reached a plateau but when I stopped eating them as much and replacing it with whole meals, the scale started moving again and whatnot, so I try to be careful with which ones I eat and how often now. I don't have a set eating schedule. Some days it is 2x a day and a bar in between. Sometimes its 5 small meals a day. There's no order because my job makes it really hard to have order. Regardless, I do try to eat 1500c a day. I portion freaking everything btw! Portion and measure!

It seems with weight training, my body is changing but not the way I would have thought. Like I said, I don't feel as good about my body now. I've lost this lean that I thought I had. You know how in the morning, you feel your smallest? I don't feel that anymore. My body just feels blah all the time. In fact, the only time I feel even kind of good is when I do eat like 1200 calories and don't work out. I don't know. I'm getting to the point that I just want to go back to running and maybe do weight training like once a week. Because I do feel bulky and bloated. But like I said, I have not gained weight according to the scale.

Please help.
