im in a similar position to you,slightly smaller but still close (5ft10, 172lbs).
im looking to be able to fight towards autumn this year at 155lbs, so im looking to lose around 12 lbs, so then i onyl have to cut 5lbs int he run up to fights.
it sounds boring and cliche, but it really is a case of eating less fast food and chocolate/sweets/crisps ect, an eating more vegatables an fruit ect.
altho having sed that,i already ate a fair amount of veg an fruit, but simply cutting down on choc an sweets an fast food has helped me lose a bit of weight.
u dont have to completly stop eating the things u like just dont binge too often. i try to stick to not eating any choc/pastry/crisp/sweet/mac ds takeaways ect in the week.this then allows me to eat pizza or wotever i want (within reason of course)on saturdays an fairly loose diet on sundays. if u dont giv urself chance to enjoy food, u wont stick to the diet for long.gettin a decent and nice tastin protein shake will help wen u get a craving for sumthin sweet (i liek sci-mx diet shake, chocolate cream flavour), an also has all the vitamins and protein u need for recouperating after workouts.
hope this helps a bit!
