Trev, just noticed that you are doing SlimFast. I am aware of the program but haven't done it before myself. Congrats on your loss so far!
Point I am making is in relation first to food, I recommend a isolate whey protein powder. It's maybe about 150 cals when made up and will give you another shake for the day. The reason being that your body needs a high amount of protein to burn fat at a good rate.
Second point is with the exercise. Do you go to the gym? Not sure if you have a membership or anything along those lines i.e. home gym? Cardio is good for all over especially the legs and mid section however if you are going to do weights on the top half you should on the bottom half as well, so not just cardio.
Here are some suggestions, again depending on your current workout routine perhaps try the following: 3 or 4 times a week;
push ups, chest press with a barbell, chin ups, lat pull down, rowing (15 mins)
3 sets of 15
If you have an iphone there is a great app called ifitness with pics and a log/chart for your entries. Also mens health mag (like the women's) have workouts featured each month and really good if you are stuck for variety or something new.
Hope that's helped.
