24 years old- 6'2" 217lbs around 12% bf. Im trying to put on some size and calculated my TDEE to be 3,397. I eat 4 meals a day and I know for a fact the two meals that are shakes (oats, egg whites, protein powder, whole milk, olive oil) put me around 3000 cals just from those two shakes. Yet im still not gaining weight. So how much over my TDEE do I need to be going to start moving the scale?
