Just a thought but remember he started DJ on 4000 calories then he was moved up to 5000 don’t think it was too long after - but I bet he was losing weight on 4000 so why then move him up to 5000 I don’t care how big you are 4000 cals has got to be enough right especially if your eating nutritionally good stuff and veg and fruit easily
eat loads of veg and protein for those cals - I remember being absolutely gobsmacked when he then said he was then on 5000
DJ needs to move away from DW take the mobility he’s gained with him (fair play to him for that) and cut a 1000
cals easily to get some weight off him quickly - I know it’s best to lose weight slowly but for his health he could do with shifting a fair few stone quicker than he has been doing
