What daily caloric intake would you suggest for a sedentary 26 year old at 360 lbs., 5'10" interested in serious weight loss (target 210)?

1800-2000 per day. Divided into 6 feedings a day, but you have to get your bum moving, and every little bit helps.
1000. Wow;you are really in dire straits. You really need to increase the calorie burn more than calorie intake.
