I recommended dropping to 2,000 or 1,800 calories a day to start with. On average, he has been eating around 4,000-6,000k a day. I have tried to stress exactly what you said about it being a lifestyle change. He always responds that he knows, and that he's been super healthy before because he used to wrestle... like 10 years ago. Ah, the glory days of fats.  Ha! Last night he actually made a "protein shake" with his new blender. Broccoli, onions, cabbage, bell peppers, and carrots, blended into a smoothie. Let's just graze past the idea of it being a protein shake. All of those are delicious as actual food on their own, I can't imagine them blended together though, it just sounds gag worthy.
