Well that's helpful.
I try

Anyway my recommendation would be don't bother buying any weights they won't be worth the outlay, if you can't afford the gym stick to cardio and bodyweight exercises while adding weight using something like a rucksack filled with heavy items.
Watch your portion sizes. Start the day with some good complex carbs and protein such as oats, wholemeal bread, eggs.
Keep your meals clean with plenty of mixed veg especially green veg such as broccoli,kale,spinach etc lean protein so eggs,steak,chicken,fish and a small amount of good carbs brown/basmati rice,brown pasta, cous cous, sweet potato.
Also read this http://forums.overclockers.co.uk/showthread.php?t=17401146 it sets out the basics of a good diet.
Stick to water when possible to drink and if you feel hungry have a drink first as you may well just be thirsty.
The first week or 2 of sticking to a better diet and avoiding all your sugary things will be hard but once you get into a routine it will become much easier and you will feel so much better.
