My questions are:
How much cardiovascular exercise should I be doing?

Secondly, I am taking vitamins and such but what should I be eating? I have put myself on a 2200-2400 calorie diet broken down to 55-60 % carbs, 25-30% protein and 15-20% fat. My goal is to lose the love handles and increase my muscle mass.

First of all, here is a short article I wrote on aerobic training.

This article will give you some fundamental information on the duration and intensity of a good aerobic workout. One quick thing, if you are just starting out only do the minimum recommended amount. This is 3 times per week for 20 minutes per session!

Your diet is solid. You are about 100 steps further than most people are because you have a caloric range in mind, and an approximation of your macronutrient percentages. The total calorie amount is really what is the most important thing for losing weight. If you simply eat less than your body uses on a daily basis, you will create a caloric deficit and you will lose weight. However, I would recommend slightly lower carbohydrates, somewhere in the 40-50% range. This lower amount of carbohydrates simply helps to keep people on their diets. I know this sounds strange, but it is blood sugar level control and stabilization that keeps people away from cravings and ultimately slipping up on their diets.

The 40-30-30 (carb, pro, fat percentages) diets have become quite popular over the last few years, for this very reason. The biggest critics of this diet are the ones that think protein only comes from a huge piece of red meat. Just remember to eat lean sources of protein like chicken, fish, egg whites, low fat dairy products or quality protein powders like Met-Rx or Myoplex. The other remark that critics of this diet say is that it is too high in fat. 30 percent fat in your diet is recommended by many other “mainstream” sources, but the key is to keep your saturated fat levels low. Quality fatty acids that come from fish like salmon, and from nuts, seeds, and fresh oils like Olive, Canola, and Flax are incredibly healthy for your body!

Look for the books “Nutrition Made Simple” by Robert Crayhon and “Fats That Heal, Fats That Kill" by Udo Erasmus. These are excellent sources of information that will break down what I have just explained in a more in-depth way!
