Finding time

I understand your problem. I am a grad student / TA, and my schedule is packed. I lost about 70 lbs in one year, and need to lose a good bit more. What I was told, and what I use MFP for, is to track calories, rather than exercise. While exercise is great, and I probably would have lost even more if I had been able to exercise consistently, my understanding is that the more important trick is eating at a calorie deficit. So, I focused on that first. I have a mental list of high-protein, and relatively low calorie convenience foods -- like a McDonald's egg mcmuffin (not shilling for them, just what came to mind). I checked a lot of stuff in the freezer section of the grocery store, too. And I stocked up on protein shakes. I started eating at a deficit, combining all of these things. The hardest thing is that these foods are not always very sustaining, but the higher protein the better. I also slowly started adding in a few things that aren't hard, that I learned to cook for myself. And I ate a lot of veggies. I counted them all, but two eggs and a bunch of veggies sauteed with cooking spray is a lot of volume, and so I felt full for quite a while. The thing that I am slowly learning to do now is walk on a treadmill and read. It is taking me a while, and I can't go very fast, but better moving a little than not at all. I am now at a point where I am trying to figure out how to fit more exercise into my daily regimen, in a way that works for me. Saying "I'm going to get up at five every morning and walk three miles!" Nope, not gonna happen. I may say it, but I'm not gonna do it. I need to build up slowly, the way I did with the food.

I work full time and attend university part time.

One of the things that works for me is to incorporate exercise throughout my day ... like climbing stairs, for example. I can usually get 25 flights in each day. And I walk as part of my commute.

Sometimes I feel like long hours studying are driven by fear; at other times I think it's down to the same macho thinking that drives people to work long hours at the office with no evidence that they're getting any more done. In reality, someone who manages their time spent actively learning while actively setting aside time for exercise and other activities is more likely to get good results, imo. If it helps, I am a college lecturer.
