He could hire a team of doctors/nutritionists/chefs/butlers/trainers/etc., pay them all $1mm a year with their only job being, "keep me on a diet and exercise regimen that guarantees me to lose weight", but he'd rather just cry fat, gold-plated tears.  He needs to get his fucking shit together.  If someone making minimum wage can do it, a billionaire can (or pay people to do as much of it for him as possible).
