I am currently taking in 500+ grams a day but my carbs are at 150. I feel if you keep you carbs low and supplement the calories from the lost carbs with protein you have more of a chance to build muscle and loose fat. This is just my opinion and it seems to work for me and a few other guys I know. I came down from a sloppy 255 to 230 and lean with doing very minimal cardio and also no gear. My caloric intake stayed the same but I just lowered carbs and upped protein. ALso I dont get as hungry since I am eating so much. Plus 5 meals are true food and 3 are from shakes. Like I said this is just my opinion and is something I tried and happens to work for me.
