Hey everyone. I'm a fresh n00bian in the world of online weight management, but I'm certainly looking forward to seeing progress. Currently around 224 lbs and about 5' 9" I wish to lose at least 24 pounds by July 10th. Among several other reasons, I'm going to be going to Peru to visit a very good friend of mine and want to impress her

.
While I'm at a loss on the idea of a "good" diet plan, here's what I surmise I'll be doing:
-1250 Daily Calorie Intake
-Two 30 minute running sessions (morning and night)
-1 vigorous weight training session every week (1 hour+)
The reason I'm confining myself so much is that, like many people, I find it hard to find the time to do anything for myself: I'm in college, I work, and I'm in a band. Homework aside, I barely have time to spend with my family and friends.
I would like some feedback from you guys on my plan. Keep in mind, this will only be effective for the next 62 days (until July 10th). After that I'll change the plan around to fit to a long-term lifestyle.
Thanks, in advance.
