He has nothing to change, he already stated he has lost 4 pounds in ~4 weeks, at that rate he will be at a somewhat healthy weight in about 20 years. Keep up the good work pal!
On a serious note, dont jump on some fad diet and think that alone will work. A guy I work with has been jumping from fad diet to fad diet for the last 5 years and has not lost a pound, its kind of funny. Go to the hotel gym and walk on the elliptical for 20-30 minutes a day or walk outside if its nice out, every damn day! Go for a hike on weekends, dont just start a thread about hiking, go fucking hike! Clean up your diet and cut out some drinking and you will be off to a good start. Im sure most things you eat are super high in sodium, cut out some of the shit and the sodium and you will most likely loose 5-10 lbs in water weight.
Or dont do anything and just keep SUJOPA'ing daily and be happy .
