I started training again last January, and I have lost approximately 25 pounds since that time. (I was 235 lbs., but I am down to 210 lbs. - which is the least I have weighed since starting college. Also, I am 6'5" and thickly built; so, 210 is pretty thin for me. I may try to add some muscle weight later this year.) Here is my exercise routine:
Monday - 3 x 10 minutes intense aerobic exercise (rowing, stairs, running) with one to two minute breaks between sets
Tuesday - strength training (circuit training followed by rowing sprints or a 1/2 mile run)
Wednesday - 1 x 30-40 minutes moderate aerobic exercise (rowing or running)
Thursday - strength training (circuit training followed by rowing sprints or a 1/2 mile run)
Friday - open gym (whatever I feel like doing for 30-40 minutes)
Saturday and Sunday - work on my house and yard and play with my children until I am absolutely exhausted and can only motivate myself to play video games
Because I exercise during the day, I typically have only 30-45 minutes to complete my routine, but I have found it to be enough time if you push yourself hard enough.
Monday through Friday, I eat bran cereal with a banana for breakfast, black coffee when I arrive at my office, a protein shake for lunch, a small snack when I get home from work, and whatever I want for dinner (typically with one alcoholic beverage...doctor's orders!). On the weekends, I eat and drink whatever I want...in moderation. I do not drink soda, and the only carbonated beverage I consume is beer. Dark chocolate is my Achilles heel...but since I am not going to live forever, I don't worry about it too much.
