I am tracking my calories in and my calories out.
I am using the Spark People recommended daily calorie intake based on my exercise routine. I then subtract from the number of calories for the day my BMR and the number of calories I burn at the gym. My goal is to achieve a negative net for the week.
The changes to my diet are less motivated by needing to limit calories (when I'm not "dieting" I usually eat about 1600 calories a day anyway), but more to just work towards overall health. More fruits, less caffeine.
I joined a gym and my routine is this: Day 1: 60 minutes on a combination of elliptical and treadmill. Day 2: 60 minutes cardio plus 20 minutes of strength training Day 3: 60 minutes cardio Day 4: Rest Day Repeat
