Hi Ollie - another Irish one here, far from home too!!!
It really depends on 2 things...your attitude & how much you actually wanna lose weight...
physically you can prepare your body by cutting down carbs & increasing your water intake before starting ...
mentally - thats the hardest part of all...but really think about how much you want this to work????
Coz - if you want it enough - it'll work, you'll turn down food & drinks and, being a bloke you'll be a goal really quickly ...remember its a choice - you are choosing to put food & alcohol on hold - until you get to your goal weight...
All the best - remember all you have to lose - is weight!
