HELP 6 ft 5 -- 470lbs! how many calories to loose weight

Hi my husband is 6 ft 5 - 470lbs , 45 years old sedentry life syle, has already lost 41 lbs and is now stuck and has lowered his calories to 2350 !

I think he needs to more , hes thinks he should eat less.I put his height weight and life style into the calorie tool and it said 3011, i'm confused!

I don't want him to give up, help please

Take a look at this tool, it's the one I use and it explains all the reasoning behind it.  If he adds just a little exercise he can burn even more.  http://www.phord.com/cc/.  Persistence is the name of the game.  Slow and steady is what is maintainable.  Tell him to keep up the hard work.

he has to increase his metabolism ...so he has to increase some form of exercise as to not plateau....good luck
