@Dennis. You’re basically on 1600 cals every day for a guy that weighs over 200lbs. That probably explains the dizziness, especially if you’ve been eating like that for a while now. When cutting you have to gradually reduce caloric intake, and even if you did, you might never have needed to go as low as 1600. Also, at such a low calorie level for a guy your size, 170g protein is not enough. You may start to lose muscle. I don’t want to give you a sales pitch, but you should check out my Total Six Pack Abs book for a scientific approach to effective cutting. If you do decide to do that program, take 2 weeks off from cutting and eat at maintenance levels to allow your metabolism to reset first.
