Being overweight is a common trait these days and there is not enough help out there. Find out how you can shed those pounds and improve yourself from within.
It's your diet. Proper diet is a tricky thing: Too many or too few calories can break you. Try reducing your calories to around 2000-2300 a day and see what happens.
Also, football is great for sprint-fitness but the long slow burn of running, cycling, swimming or similar will likely get your metabolism going a lot better and help you burn those calories more effectively.
As we were discussing yesterday mate, just make a plan, try and stick to it and more importantly keep a record of how you get on. That way you'll see your fitness improve and the loss of weight will come along with it!
