12 pack down to 6 pack

I'm aiming to turn my beer belly back into its former 6 pack. I hate that I've put weight on, fortunately my new room is up a lot of stairs and the building is halfway up a steep hill. and the college where I work has lots of steps. and already I think the bellys getting smaller. but till its gone I'm still listening to rageing speed horn "Bellies gonna get ya! Bellies gonna get ya! Bellies gonna get ya!".
I'm aiming to:

• Eat less red meat
• Drink less alcohol
• Eat more salad
• Eat more fruit and veg
• fewer fast foods
• more fresh food

If anyone has any recommendations let me know.
