I agree that the TOTM will definitely have that effect on your weight. I can gain 2 lbs overnight during that special time!
As for the feeling really hungry and eating more when you exercise, I was there for a while too. I did a couple things to pull me out of that cycle and benefit more from the exercise.
1.) I would suggest planning out a few snacks for after your workout that are super high in protein and filling (this will help with both muscle recovery and gaining lean muscle mass, which it is my understanding that you are after). When I go to the gym, I have a piece of fruit and a protein bar waiting for me in the car. The sweetness and juiciness of the fruit works for me right after I finish and about 30 minutes later, the protein bar fills me up. I would experiment with a few good recovery type foods and plan on eating them instead of trying to not eat and then eating the wrong things or too much of something.
2.) I mentally prepare for a tough exercise by getting excited about the extra calories I am going to burn. This is a tough one that I learned over time, but works well for me. Basically, I convince myself that I can "eat more later" and never really get to "later." I'm not sure I am explaining myself well....but every time I do a tough workout and want a Big Mac afterwards, I just keep thinking about how much the scale is going to drop because it was an exercise day and keep telling myself not to "waste" all that effort on exercise. I tell myself that I worked hard today and I am not going to ruin it, but I can eat more tomorrow. By the time tomorrow comes around, I no longer feel the need to pig out and (since I weigh myself daily) am usually excited by that morning's weigh in.
3.) Water. Lots and lots of water. When you exercise, you are not always hungry as much as thirsty but your brain doesn't know the difference. I eat my piece of fruit and then "can't" eat again until I drain my water bottle. When I sweat a lot, sometimes I need a PowerAde Zero or zero calorie sports drink as well.
Anyway, it's a process and these are just things that work for me. I hope this helps you find what works for you!
