Im 12 stone, and dont have enough time to check how much calories im intaking, id rather do it in set meals & snacks for the week but i dont have a proper nutrition plan and my gym doesn't provide them; so does anyone have any idea how much and what i should eat? thanks for reading.

That is a very broad question bro.You need to know your goals and all.
there are lots of diets listed here on the site

ya if you can tell us what your goals are we might be able to help further but it would be easier for you if you just looked into the nutrition section so you can find a diet that works for you

Hmmmm help with regards to diets are always tough unless when we know your goals and a "ball park figure" (the more precise the better, obviously) of your diet in terms of calories (grams of protein, carbohydrates, and fats), and what you eat at what times with regards to your workout.

Being at 12 "stone" you could either bulk up or cut down depending on your goals, so let us know your goals so that we can help you as much as possible! And answers like "Build muscle and lose fat" are not that clear and effective primarily because the human body is much more efficient at one or the other.
