1. WAY too much cardio. I suggest he try some HIIT sessions (15mins) maybe 3x week and maybe he could do some
steady state cardio another day.
2.
WEight training. If he isn't doing it, he has to start. Tell him to lift and lift heavy. 3x full body sessions a week may be a good place to start - focus on compound exercises - pullups/chinups, squats, deadlifts etc.
3. Food. No he is not eating often enough and probably not eating enough calories (specifics will be needed for this) Six meals a day, smaller meals, spaced 2-3 hrs apart. Protein with every meal. Good fats - olive oil, fish oil, nuts etc. are not to be feared. At his size of 19stones (266lbs) he should be able to lose weight quite easily at 2660 cals (that 10 per lb of BW) more food, more often, better choices.
4. Tell him to get his a** online himself and get advice from others - if he is really serious about this, he should put in the time and effort necessary.
Thats my 2cents
