If losing weight is not your goal (which I'm guessing it isn't judging by your post and the weight you listed), you can skip the fat blasting phase and move on to the second phase. Another potential option would be that if the calorie calculator puts you in between meal plan calorie amounts (IE, say it puts you at 2100), you could start with the fat blaster phase for the high protein and then add the additional calories via carbs, which is actually what I've done before.
Ultimately, remember that the guide is just that--a guide, which uses an average. So if you eat the caloric amount it gives you, and are consistently starving and low on energy, then you can up the calories as needed.
Hope that helps.
