Simple answer: yes!
However, it’s tough to tell someone exactly what calories to eat no matter if bulking, cutting, or maintaining. But, I mos def think your net cals are WAY too low! 2000 minus your workout bout, say 400 cals = 1600! I calculate an approx maint. cal need of 2400-2500, so you aren’t eating enough food to preserve LBM and you might start drooling at the site of your pet!
Question? Do you have an idea of how many cals you were consuming when you were just maintaining your weight? Since you are increasing your exercise from cardio and lifting, that along will make a significant dent in your calorie needs for the day, so you don’t have to cut back on eating as much as you might think. If you know your maint. cals, simply subtract 500-700 a day by a combination of diet and exercise.
Hopefully you have an idea of your maint. cal needs. If not, I would use this to help find a good starting place. Based on a helpful formula I have found here on T-Nation and my professional training, you take your LBM (151) X as your basic protein needs in grams, X 4 cals per gram = 2400-2500 calories (for a slower metabolism). This is approx your maint. cal needs. If you want to loose a pound per week, subtract 500 cals from this = 1900-2000. This is you calorie net. Therefore, you can do one of three things. 1, eat 1900 cals per day, with no exercise. 2, eat about 2200 per day, burning 300 per workout. Or, eat 2400 per day, but burn 500 cals per workout (or some combination that get’s you a net of 1900-2000 cals). Make sense?
This is only a starting place, but according to this calculation, if you choose #2 or 3, you will be able to eat more calories which will help you avoid losing LBM and starving to death!
BTW, on the T-Dawg diet, try eating closer to 50 grams of carbs in the AM on non-lifting days. On lifting days, 50 in the AM, 50 PWO, but always low-glycemic since your BF is higher.
Hope this helps,
