This is my 2 pence worth bud plenty of good advice on here.
I'd suggest fasted morning cardio at steady state i.e walking/cycling on a empty stomach in morning before breakfast 30-45 mins. I've always done it and all the lads I train/train with do it ready for shows/contests ect there on a different level but the same principle applies "burn more fat on a empty stomach"
Also have a protien shake in between meals to keep hunger pangs always protien leaves you fuller for longer.
No carbs after 4-5 in evening. Try to have them earlier in day breakfast and lunch.
Try to do as much cardio as possible start off steady state (easy on your body and gets you back into swing of it) then when you feel fitter start interval training to blitz even more fat.
Also if you can join a gym and do weight training workout youl burn more fat shifting iron for 45 mins than you will in a 60min cardio session plus youl burn fat for much longer after lifting weights.
If your 6ft 8" you could be a right unit! I train with a guy your height and he's 21stone but just pure muscle! I myself am just over 6ft1 and 18stone and I'm now cutting down after winter bulking so I'm using the advice I just give you.
Don't want to sound gay but I'd love to train you in my gym I'd get you massive the girls would be fighting over you!
If you want anymore advice or anything feel free to pm me bud. And good luck keep at it and youl reep the rewards.
